[libvirt] [PATCH 0/2] virsh: allow to specify pci address with attach-interface
by KAMEZAWA Hiroyuki 14 Dec '11

14 Dec '11

Now, at using attach-interface, pci address of the device is determined automatically. This is nice. But in some situation, users may want to specify pci address by hand. For example, when users want to use multifunction pci device, he need to specify pci slot. This patch allows to specify pci address with attach-interface. Then, this kind of script can run to assign multiple nics in a slot. == #!/bin/bash -x DOM=$1 SLOT=$2 NUM=$3 for i in `seq 0 $NUM`; do virsh attach-interface --domain $DOM --type='network' --source=default\ --persistent --model=virtio --address=pci:0000:00:$SLOT:0$i --multifunction; done == Because I moved placement of some functions in virsh.c, diffstat seems big... virsh.c | 948 ++++++++++++++++++++++++++++++++------------------------------ virsh.pod | 4 2 files changed, 495 insertions(+), 457 deletions(-) Thanks, -Kame

[libvirt] [PATCH v3] virsh: Add option to undefine storage with domains
by Peter Krempa 13 Dec '11

13 Dec '11

Add an option for virsh undefine command, to remove associated storage volumes while undefining a domain. This patch alows the user to remove associated (libvirt managed ) storage volumes while undefining a domain. The new option --storage for the undefine command takes a string argument that consists of comma separated list of target or source path of volumes to be undefined. Volumes are removed after the domain has been successfuly undefined, If a volume is not part of a storage pool, the user is warned to remove the volume in question himself. Option --wipe-storage may be specified along with this, that ensures the image is wiped before removing. Option --remove-all-storage enables the user to remove all storage. The name is chosen long as the users shoudl be aware what they're about to do. --- Changes to v2 based on reveiw by Eric: ( http://www.redhat.com/archives/libvir-list/2011-September/msg00481.html ) - First undefine the domain, then undefine volumes - Add option to remove all volumes - Fix typos and strange wordings - Change retur value to failure if some operations on volumes fail. tools/virsh.c | 143 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ tools/virsh.pod | 18 +++++++ 2 files changed, 161 insertions(+), 0 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index d58b827..281ffa9 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -1924,6 +1924,13 @@ static const vshCmdInfo info_undefine[] = { static const vshCmdOptDef opts_undefine[] = { {"domain", VSH_OT_DATA, VSH_OFLAG_REQ, N_("domain name or uuid")}, {"managed-save", VSH_OT_BOOL, 0, N_("remove domain managed state file")}, + {"storage", VSH_OT_DATA, VSH_OFLAG_NONE, + N_("remove associated storage volumes (comma separated list of targets " + "or source paths) (see domblklist)")}, + {"remove-all-storage", VSH_OT_BOOL, 0, + N_("remove all associated storage volumes (use with caution)")}, + {"wipe-storage", VSH_OT_BOOL, VSH_OFLAG_NONE, + N_("wipe data on the removed volumes")}, {"snapshots-metadata", VSH_OT_BOOL, 0, N_("remove all domain snapshot metadata, if inactive")}, {NULL, 0, 0, NULL} @@ -1940,6 +1947,9 @@ cmdUndefine(vshControl *ctl, const vshCmd *cmd) /* User-requested actions. */ bool managed_save = vshCommandOptBool(cmd, "managed-save"); bool snapshots_metadata = vshCommandOptBool(cmd, "snapshots-metadata"); + bool wipe_storage = vshCommandOptBool(cmd, "wipe-storage"); + bool remove_storage = false; + bool remove_all_storage = vshCommandOptBool(cmd, "remove-all-storage"); /* Positive if these items exist. */ int has_managed_save = 0; int has_snapshots_metadata = 0; @@ -1949,6 +1959,22 @@ cmdUndefine(vshControl *ctl, const vshCmd *cmd) bool snapshots_safe = false; int rc = -1; int running; + /* list of volumes to remove along with this domain */ + char *volumes = NULL; + const char *volume; + char *saveptr = NULL; + char *def = NULL; + char *source = NULL; + char *target = NULL; + int i; + + xmlNodePtr *vol_nodes = NULL; + int nvolumes = 0; + xmlXPathContextPtr ctxt = NULL; + xmlDocPtr doc = NULL; + virStorageVolPtr vol = NULL; + bool vol_del_failed = false; + if (managed_save) { flags |= VIR_DOMAIN_UNDEFINE_MANAGED_SAVE; @@ -1965,6 +1991,18 @@ cmdUndefine(vshControl *ctl, const vshCmd *cmd) if (!(dom = vshCommandOptDomain(ctl, cmd, &name))) return false; + /* check if a string that should contain list of volumes to remove is present */ + if (vshCommandOptString(cmd, "storage", (const char **)&volumes) > 0) { + /* caution volumes has to be re-assigned as it would be doulbe freed */ + volumes = vshStrdup(ctl, volumes); + + if (remove_all_storage) { + vshError(ctl, _("Specified both --storage and --remove-all-storage")); + goto cleanup; + } + remove_storage = true; + } + /* Do some flag manipulation.

[libvirt] issues with migrating using copy-storage-all
by Reinier Schoof 13 Dec '11

13 Dec '11

Hi, today I was trying to use the --copy-storage-all feature of virsh migrate, in an attempt to migrate KVM-instances to another storage backend. Doing so, I ran into some trouble: First of all, it turned out the disk image-file has to be present on the receiving end of the migration. When, just to check, this disk image is smaller than the original image, migration suddenly stops (after filling the maximum size of the too small disk image). This is expected behaviour ofcourse. But when I fix the disk image to the right size and start the migration again, the migration fails immediately, the domain is -undefined- and crashes. Qemu log showed: kvm: block.c:2889: bdrv_set_in_use: Assertion `bs->in_use != in_use' failed. 2011-12-09 10:58:16.211: shutting down Is this behaviour known to you guys? Also, when I migrate a domain (10G qcow2 disk image, which is only used for 1GB), the qcow2 image on the receiving end shows 10G for both 'virtual disk' and 'disk size', while this was 10G and 1G respectively on the sending end. Why is the image expanded? Or is this a limitation of the copy-storage-all? How does the copy-storage-all function works for raw disk images? Does it send incremental copies of blocks which are written too since the migration is started? Thanks in advance for your help! Reinier Schoof -- TransIP BV | https://www.transip.nl/

[libvirt] Audit records on suspend/pause
by Marcelo Cerri 13 Dec '11

13 Dec '11

Hi, I'd like to know if libvirt sends an event to audit system when a guest is suspended. I took a look at source code and I noticed that libvirt already have a good support for auditing life cycle events, but I couldn't find any events being sent to audit system when a guest is suspended. Thanks, Marcelo

[libvirt] add a qemu-specific event register API, to passthough the new events come from qemu
by shaohef＠linux.vnet.ibm.com 13 Dec '11

13 Dec '11

From: Shao He Feng <shaohef(a)linux.vnet.ibm.com> Basically, this feature can go along with qemu monitor passthrough. That way, if we use new commands in the monitor that generate new events, we want some way to receive those new events too. In order to test this patch, see the attached python test case. When domains are started, it will be able to catch RESUME events.

Hi .well I am trying to use virtioballon driver on my KVM host . I have assigned 400 MB current memory to my guest The ballon size is 600MB but when I used all the 400MB of guest the RAM of guest is not increasing. I watch the ram usage by running following command #free -m But the guest is only using memory upto 400MB after that the process is killed . I don't see the ballon driver coming into picture.

[libvirt] [PATCH]add a qemu-specific event register API, to passthough the new events come from qemu
by ShaoHe Feng 12 Dec '11

12 Dec '11

Basically, this feature can go along with qemu monitor passthrough. That way, if we use new commands in the monitor that generate new events, we want some way to receive those new events too. In order to test this patch, see the attached python test case. When domains are started, it will be able to catch RESUME events. and the attached 0002-for-testing-the-new-qemu-specific-regiater-API.patch is used to test the c code API. # ./tools/virsh -c qemu:///system virsh # register-event RESUME virsh # start domain Signed-off-by: Shao He Feng <shaohef(a)linux.vnet.ibm.com> --- daemon/libvirtd.h | 12 +- daemon/remote.c | 195 ++++++++++++++++++- include/libvirt/libvirt-qemu.h | 11 + include/libvirt/libvirt.h.in | 17 ++- python/generator.py | 26 ++- python/libvirt-override-virConnect.py | 14 ++- python/libvirt-qemu-override.c | 140 +++++++++++++ python/libvirt-qemu-override.py | 41 ++++ src/conf/domain_event.c | 347 +++++++++++++++++++++++++++++++-- src/conf/domain_event.h | 49 +++++- src/driver.h | 14 ++ src/libvirt-qemu.c | 190 ++++++++++++++++++ src/libvirt_private.syms | 6 + src/libvirt_qemu.syms | 5 + src/qemu/qemu_driver.c | 42 ++++ src/qemu/qemu_monitor.c | 10 + src/qemu/qemu_monitor.h | 8 + src/qemu/qemu_monitor_json.c | 36 ++++ src/qemu/qemu_process.c | 24 +++ src/remote/qemu_protocol.x | 33 +++- src/remote/remote_driver.c | 153 ++++++++++++++- src/remote/remote_protocol.x | 9 +- src/remote_protocol-structs | 5 + 23 files changed, 1353 insertions(+), 34 deletions(-) mode change 100644 => 100755 python/libvirt-override-virConnect.py mode change 100644 => 100755 python/libvirt-override-virStream.py mode change 100644 => 100755 python/libvirt-override.py create mode 100644 python/libvirt-qemu-override.py diff --git a/daemon/libvirtd.h b/daemon/libvirtd.h index c8d3ca2..e3e1c40 100644 --- a/daemon/libvirtd.h +++ b/daemon/libvirtd.h @@ -38,6 +38,16 @@ # endif # include "virnetserverprogram.h" +/* limit the number unknow event of an conncet can register */ +#define VIR_DOMAIN_EVENT_NAME_LAST 512 +struct domainEventNameCallBackStatus { + /* counter the number of unknow event registered */ + int eventNameCallBackCounter;

[libvirt] make uninstall fails

Hey all, I just noticed that make uninstall from the git HEAD fails: rmdir /etc/sasl2/ rmdir: failed to remove `/etc/sasl2/': Directory not empty it's correct that /etc/sasl2 should not be removed, as it has other files in it, so I think this removal should be more targeted, although I haven't investigated what should be removed when uninstalling.

[libvirt] [PATCH] qemu: Disable EOF processing during qemuDomainDestroy
by Jiri Denemark 12 Dec '11

12 Dec '11

When destroying a domain qemuDomainDestroy kills its qemu process and starts a new job, which means it unlocks the domain object and locks it again after some time. Although the object is usually unlocked for a pretty short time, chances are another thread processing an EOF event on qemu monitor is able to lock the object first and does all the cleanup by itself. This leads to wrong shutoff reason and lifecycle event detail and virDomainDestroy API incorrectly reporting failure to destroy an inactive domain.

[libvirt] [PATCH v2 0/4] Interface pools and passthrough mode
by Shradha Shah 12 Dec '11

12 Dec '11

Interface Pools and Passthrough mode: Current Method: The passthrough mode uses a macvtap direct connection to connect each guest to the network. The physical interface to be used is picked from among those listed in <interface> sub elements of the <forward> element. The current specification for <forward> extends to allow 0 or more <interface> sub-elements: Example: <forward mode='passthrough' dev='eth10'/> <interface dev='eth10'/> <interface dev='eth12'/> <interface dev='eth18'/> <interface dev='eth20'/> </forward> However with an ethernet card with 64 VF's or more, the above method gets tedious on the system. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. Proposed Method: The 4 patches provided: i) Introduce a new element 'pf' to implicitly create an interface pool of all the Virtual Functions attached to the specified Physical Function. ii) Modify the networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice API to use the above mentioned interface pool in the passthrough mode. Hence Libvirt will now support both the methods mentioned below: * Explicit interface list. App inputs: <forward mode='passthrough'> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> </forward> libvirt does not change XML * Automatically interface list from PF. App inputs: <forward mode='passthrough'> <pf dev='eth0'/> </forward> libvirt expands XML to be <forward mode='passthrough'> <pf dev='eth0'/> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> </forward> In the above case we need to differentiate between the implicit and explicit interface pool, which can be done by comparing the dumpxml from active and inactive domains. This will need the addition of the flag VIR_NETWORK_XML_INACTIVE to virNetworkGetXMLDesc() as mentioned in a previous suggestion. I will post this as a separate patch series. Shradha Shah (4): Added function pciSysfsFile to enable access to the PCI SYSFS files. Added Function virNetDevGetVirtualFunctions Adding the element pf to network xml.

12 Dec '11

Network disks don't have paths to be resolved or files to be checked for ownership. ee3efc41e6233e625aa03003bf3127319ccd546f checked this for some image label functions, but was partially reverted in a refactor. This finishes adding the check to each security driver's set and restore label methods for images.

[libvirt] Virtio Balloon Dynamic behaviour ??
by Pankaj Rawat 12 Dec '11

12 Dec '11

Hi all, I want to be clear in details regarding Virtio balloon Driver in RHEL 6.1 KVM hypervisor In documentations it is written that Virtio balloon driver allow the guest to expand its memory dynamically . Now I want to know the meaning of dynamically ... Whether it means 1) We can change the memory of guest using libvirt API only i.e by using virsh setmem command at runtime (VERIFIED) 2) Or the guest itself can check that it is running out of memory so it request host for some memory and when the host respond by giving back memory it expands its memory size. Which is automation The 1st option is working fine Now can anyone tell me that memory expantion can be done dynamically(point 2) also DISCLAIMER: ----------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.

[libvirt] (no subject)
by Osier Yang 10 Dec '11

10 Dec '11

Hi, all This is a basic implementation of libvirt Native Linux KVM Tool driver. Note that this is just made with my own interest and spare time, it's not an endorsement/effort by Red Hat, and it isn't supported by Red Hat officially. Basically, the driver is designed as *stateful*, as KVM tool doesn't maintain any info about the guest except a socket which for its own IPC. And it's implemented by using KVM tool binary, which is name "kvm" currently, along with cgroup controllers "cpuacct", and "memory" support. And as one of KVM tool's pricinple is to allow both the non-root and root user to play with. The driver is designed to support root and non-root too, just like QEMU does. Example of the connection URI: virsh -c kvmtool:///system virsh -c kvmtool:///session virsh -c kvmtool+unix:///system virsh -c kvmtool+unix:///session The implementation can support more or less than 15 virsh commands currently, including basic domain cycle operations (define/undefine, start/destroy, suspend/resume, console, setmem, schedinfo, dumpxml, ,autostart, dominfo, etc.) About the domain configuration: * "kernel": must be specified as KVM tool only support boots from the kernel currently (no integration with BIOS app yet). * "disk": only virtio bus is supported, and device type must be 'disk'. * "serial/console": only one console is supported, of type serial or virtio (can extend to support multiple console as long as kvm tool supports, libvirt already supported mutiple console, see upstream commit 0873b688c). * "p9fs": only support specifying the source dir, and mount tag, only type of 'mount' is supported. * "memballoon": only virtio is supported, and there is no way to config the addr. * Multiple "disk" and "p9fs" is supported. * Graphics and network are not supported, will explain below. Please see "[PATCH 7/8]" for an example of the domain config. (which contains all the XMLs supported by current implementation). The problems of Native Linux KVM Tool from libvirt p.o.v: * Some destros package "qemu-kvm" as "kvm", also "kvm" is a long established name for "KVM" itself, so naming the project as "kvm" might be not a good idea. I assume it will be named as "kvmtool" in this implementation, never mind this if you don't like that, it can be updated easily. :-) * It still doesn't have an official package yet, even no "make install". means we have no way to check the dependancy and do the checking when 'configure'. I assume it will be installed as "/usr/bin/kvmtool" in this implementation. This is the main reason which can prevents upstream libvirt accepting the patches I guess. * Lacks of options for user's configuration, such as "-vnc", there is no option for user to configure the properties for the "vnc", such as the port. It hides things, doesn't provide ways to query the properties too, this causes problems for libvirt to add the vnc support, as vnc clients such as virt-manager, virt-viewer, have no way to connect the guest. Even vncviewer can't. * KVM tool manages the network completely itself (with DHCP support?), no way to configure, except specify the modes (user|tap|none). I have not test it yet, but it should need explicit script to setup the network rules(e.g. NAT) for the guest access outside world. Anyway, there is no way for libvirt to control the guest network. * There is a gap about the domain status between KVM tool and libvirt, it's caused by KVM tool unlink()s the guest socket when user exits from console (both text and graphic), but libvirt still think the guest is running. * KVM tool uses $HOME/.kvm_tool as the state dir, and no way to configure, I made a small patch to allow KVM tool accept a ENV variable, which is "KVM_STATE_DIR", it's used across the driver. I made a simple patch against kvm tool to let the whole patches work. See "[PATCH] kvm tools.....". As generally we want the state dir of a driver can be "/var/run/libvirt/kvmtool/..." for root user or "$HOME/.libvirt/kvmtool/run" for non-root user. * kvmtoolGetVersion is just broken now, as what "./kvm version" returns is something like "3.0.rc5.873.gb73216", however, libvirt wants things like "2.6.40.6-0". This might be not a problem as long as KVM tool has a official package. * console connection is implemented by setup ptys in libvirt, stdout/stderr of kvm tool process is redirected to the master pty, and libvirt connects to the slave pty. This works fine now, but it might be better if kvm tool could provide more advanced console mechanisms. Just like QEMU does? * Not much ways existed yet for external apps or user to query the guest informations. But this might be changed soon per KVM tool grows up quickly. * It will be quite desireable if kvm tool could report the capabilities, of which is lacked by QEMU forever (seems so), it causes much pain for upper layer mgmt apps. See the RFC by Daniel Berrange in QEMU list for more details: http://lists.nongnu.org/archive/html/qemu-devel/2010-06/msg00921.html As a conclusion, it seems to me that KVM tool dosesn't consider too much about the interface for upper layer management tools, (generally, upper layer apps will want good interface to set/get), which might be no good for KVM tool future development. Thoughts, and opinions? Thanks.

[libvirt] [PATCH] test: replace deprecated "fedora-13" machine with "pc-0.13"
by Laine Stump 10 Dec '11

10 Dec '11

One of the xml tests in the test suite was created using a now-deprecated qemu machine type ("fedora-13", which was only ever valid for Fedora builds of qemu). Although strictly speaking it's not necessary to replace it with an actual supported qemu machine type (since the xml in question is never actually sent to qemu), this patch changes it to the actually-supported "pc-0.13" just for general tidiness. (Also, on some Fedora builds which contain a special patch to rid the world of "fedora-13", having it mentioned in the test suite will cause make check to fail.) --- .../qemuxml2argv-encrypted-disk.args | 2 +- .../qemuxml2argv-encrypted-disk.xml | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.args b/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.args index 1da0073..c6634fd 100644 --- a/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.args +++ b/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.args @@ -1,5 +1,5 @@ LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin HOME=/root USER=root LOGNAME=root \ -/usr/bin/qemu -S -M fedora-13 -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name \ +/usr/bin/qemu -S -M pc-0.13 -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name \ encryptdisk -uuid 496898a6-e6ff-f7c8-5dc2-3cf410945ee9 -nographic -nodefconfig \ -nodefaults -chardev socket,id=monitor,\ path=//var/lib/libvirt/qemu/encryptdisk.monitor,server,nowait -mon \ diff --git a/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.xml b/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.xml index f5e5d74..fdcf624 100644 --- a/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.xml +++ b/tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.xml @@ -5,7 +5,7 @@ <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> - <type arch='i686' machine='fedora-13'>hvm</type> + <type arch='i686' machine='pc-0.13'>hvm</type> <boot dev='hd'/> </os> <clock offset='utc'/> -- 1.7.7.3

[libvirt] [PATCH] network: don't add iptables rules for externally managed networks
by Laine Stump 10 Dec '11

10 Dec '11

From: Laine Stump <laine(a)redhat.com> This patch addresses https://bugzilla.redhat.com/show_bug.cgi?id=760442 When a network has any forward type other than route, nat or none, the network configuration should be done completely external to libvirt - libvirt only uses these types to allow configuring guests in a manner that isn't tied to a specific host (all the host-specific information, in particular interface names, port profile data, and bandwidth configuration is in the network definition, and the guest configuration only references it). Due to a bug in the bridge network driver, libvirt was adding iptables rules for networks with forward type='bridge' etc. any time libvirtd was restarted while one of these networks was active. This patch eliminates that error by only "reloading" iptables rules if forward type is route, nat, or none. --- src/network/bridge_driver.c | 18 +++++++++++++----- 1 files changed, 13 insertions(+), 5 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 63338a2..44c80e1 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -1470,14 +1470,22 @@ networkReloadIptablesRules(struct network_driver *driver) VIR_INFO("Reloading iptables rules"); for (i = 0 ; i < driver->networks.count ; i++) { - virNetworkObjLock(driver->networks.objs[i]); - if (virNetworkObjIsActive(driver->networks.objs[i])) { - networkRemoveIptablesRules(driver, driver->networks.objs[i]); - if (networkAddIptablesRules(driver, driver->networks.objs[i]) < 0) { + virNetworkObjPtr network = driver->networks.objs[i]; + + virNetworkObjLock(network); + if (virNetworkObjIsActive(network) && + ((network->def->forwardType == VIR_NETWORK_FORWARD_NONE) || + (network->def->forwardType == VIR_NETWORK_FORWARD_NAT) || + (network->def->forwardType == VIR_NETWORK_FORWARD_ROUTE))) { + /* Only the three L3 network types that are configured by libvirt + * need to have iptables rules reloaded. + */ + networkRemoveIptablesRules(driver, network); + if (networkAddIptablesRules(driver, network) < 0) { /* failed to add but already logged */ } } - virNetworkObjUnlock(driver->networks.objs[i]); + virNetworkObjUnlock(network); } } -- 1.7.7.3

[libvirt] [PATCH 0/6] Allow minimal bandwidth guarantee
by Michal Privoznik 09 Dec '11

09 Dec '11

Since 0.9.4 release libvirt supports setting some QoS attributes on virtual bridges and/or virtual interfaces. Average and peak rate, namely. It lacks minimal guaranteed bandwidth aka 'floor' attribute, though. This patch set tries to fill that hole. However, there are some things you want to know before diving into individual patches: 1) Hierarchical shaping The whole magic hidden in here: Classes [1] can have multiple children and form a tree. A class can borrow unused bandwidth from other sibling classes up to its 'ceil'. This is done in kernel, though. Classes does not share any info among interfaces. Therefore we need to group traffic from domain interfaces so it goes over one point (a bridge). It is now obvious why this functionality is limited to VIR_DOMAIN_NET_TYPE_NETWORK only as the other bridged network type (VIR_DOMAIN_NET_TYPE_BRIDGE:) is meant to be not managed or touched by libvirt at all. This patches build that tree of classes. On network startup, a root class with one child class are created. This child is supposed to be catchment for all interfaces which will ever be plugged and don't have any 'floor'. Once we have network prepared, an interface may be plugged in. That means on a domain startup, as we create virtual devices for a domain and plug them into a bridge, we can create separate class for created interface (if it is needed = has 'floor' set). Class are distinguished by u_int16 identifier which: - needs to be unique among one bridge, obviously - we want to keep, and pass on interface unplugging 2) Network status file Because of the class ID I am mentioning above, I found myself in need of saving next free class ID among with network, so it survives daemon reboots. That's what 5th patch does actually. On interface plug event an unique class ID is taken and on successful QoS set it is stored into an interface. Having said that, domain status XML was extended to keep pair <interface alias; class id> 3) Tying interface traffic with class is done via filter [2]. Filters direct packets into a classes during which packet undergoes examination. Such filter is caller classifier. For example, filter classify packets based on their marks, src/dest ip address, port, etc. And here comes another magic trick. But not so nice as the first one. Libvirt does not know anything about guest (interface) ip address(es). The only thing that libvirt knows for sure is MAC address. But for some reason, filters refuse to use ebtables marks even if iptables marks works well. Filters, however does not support classifying by MAC address. Well, not directly. u32 filter can match any part of a packet at any offset. Offset 0 is start of IP header. And offsets can be negative :) 1: http://tldp.org/HOWTO/Traffic-Control-HOWTO/components.html#c-class 2: http://tldp.org/HOWTO/Traffic-Control-HOWTO/components.html#c-filter Michal Privoznik (6): bandwidth: add new 'floor' attribute bandwidth: Create hierarchical shaping classes bandwidth: Create (un)plug functions bandwidth: Create network (un)plug functions network: Create status files domain: Keep assigned class_id in domstatus XML daemon/libvirtd.c | 3 + docs/formatdomain.html.in | 21 +++- docs/schemas/networkcommon.rng | 5 + po/POTFILES.in | 1 + src/conf/domain_conf.c | 10 +- src/conf/domain_conf.h | 1 + src/conf/netdev_bandwidth_conf.c | 81 +++++++++++--- src/conf/netdev_bandwidth_conf.h | 3 +- src/conf/network_conf.c | 220 ++++++++++++++++++++++++++++++++------ src/conf/network_conf.h | 9 ++ src/libvirt_network.syms | 2 + src/libvirt_private.syms | 2 + src/lxc/lxc_driver.c | 3 +- src/network/bridge_driver.c | 109 +++++++++++++++++-- src/network/bridge_driver.h | 7 ++ src/qemu/qemu_command.c | 20 +++- src/qemu/qemu_domain.c | 66 +++++++++++- src/qemu/qemu_process.c | 12 ++ src/util/virnetdevbandwidth.c | 205 ++++++++++++++++++++++++++++++++++-- src/util/virnetdevbandwidth.h | 19 +++- src/util/virnetdevmacvlan.c | 2 +- 21 files changed, 710 insertions(+), 91 deletions(-) -- 1.7.3.4

[libvirt] FYI: SpecVirt results using libvirt + KVM
by Daniel P. Berrange 09 Dec '11

09 Dec '11

Some folks may be aware of the SpecVirt benchmark, where KVM is giving the competition something to worry about :-) http://www.spec.org/virt_sc2010/results/ >From the POV of libvirt uses though, there has been one annoyance with the previously submitted results though, in that they have been invoking the KVM command line directly. This has made it harder for people who are deploying KVM using libvirt to replicate the optimal configurations. I'm pleased to be able to point out that the latest result published for KVM by IBM has in fact been done using libvirt! You can clearly see how the guests are being configured with libvirt and the results demonstrate that using libvirt to manage KVM does not involve sacrificing any of the performance that KVM offers: http://www.spec.org/virt_sc2010/results/res2011q4/ This can only continue to get better as our communities work together to add more performance related features to both libvirt and KVM :-) Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|

[libvirt] [RFC] BlockJob: Support sync/async virDomainBlockJobAbort
by Adam Litke 09 Dec '11

09 Dec '11

Qemu has changed the semantics of the "block_job_cancel" API. Originally, the operation was synchronous (ie. upon command completion, the operation was guaranteed to be completely stopped). With the new semantics, a "block_job_cancel" merely requests that the operation be cancelled and an event is triggered once the cancellation request has been honored. To adopt the new semantics while preserving compatibility I propose the following updates to the virDomainBlockJob API: A new block job event type VIR_DOMAIN_BLOCK_JOB_CANCELLED will be recognized by libvirt. Regardless of the flags used with virDomainBlockJobAbort, this event will be raised whenever it is received from qemu. This event indicates that a block job has been successfully cancelled. A new extension flag VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC will be added to the virDomainBlockJobAbort API. When enabled, this function will operate asynchronously (ie, it can return before the job has actually been cancelled). When the API is used in this mode, it is the responsibility of the caller to wait for a VIR_DOMAIN_BLOCK_JOB_CANCELLED event or poll via the virDomainGetBlockJobInfo API to check the cancellation status. Without the VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC flag, libvirt will internally poll using qemu's "query-block-jobs" API and will not return until the operation has been completed. API users are advised that this operation is unbounded and further interaction with the domain during this period may block. This patch implements the new event type, the API flag, and the polling. The main outstanding issue is whether we should bound the amount of time we will wait for cancellation and return an error. Comments on this proposal?

[libvirt] [PATCH] nwfilter: cleanup return codes in nwfilter subsystem
by Stefan Berger 09 Dec '11

09 Dec '11

This patch cleans up return codes in the nwfilter subsystem. Some functions in nwfilter_conf.c (validators and formatters) are keeping their bool return for now and I am converting their return code to true/false. All other functions now return -1 on failure and 0 on success. [I searched for all occurences of ' 1;' and checked all 'if ' and adapted where needed. After that I did a grep for 'NWFilter' in the source tree.] --- src/conf/nwfilter_conf.c | 127 ++++++------- src/conf/nwfilter_params.c | 22 +- src/nwfilter/nwfilter_driver.c | 2 src/nwfilter/nwfilter_ebiptables_driver.c | 286 +++++++++++++++--------------- src/nwfilter/nwfilter_gentech_driver.c | 78 ++++---- src/nwfilter/nwfilter_learnipaddr.c | 47 ++-- src/qemu/qemu_command.c | 3 src/qemu/qemu_process.c | 2 src/uml/uml_conf.c | 2 9 files changed, 290 insertions(+), 279 deletions(-) Index: libvirt-acl/src/conf/nwfilter_conf.c =================================================================== --- libvirt-acl.orig/src/conf/nwfilter_conf.c +++ libvirt-acl/src/conf/nwfilter_conf.c @@ -214,23 +214,24 @@ static const char state_str[] = " * @attr: The attribute to look up * @res: Pointer to string pointer for result * - * Returns 1 if value was found with result returned, 0 otherwise. + * Returns 0 if value was found with result returned, -1 otherwise. * * lookup a map entry given the integer. */ -static bool +static int intMapGetByInt(const struct int_map *intmap, int32_t attr, const char **res) { int i = 0; - bool found = 0; + int found = false; + while (intmap[i].val && !found) { if (intmap[i].attr == attr) { *res = intmap[i].val; - found = 1; + found = true; } i++; } - return found; + return (found) ? 0 : -1; } @@ -241,26 +242,27 @@ intMapGetByInt(const struct int_map *int * @casecmp : Whether to ignore case when doing string matching * @result: Pointer to int for result * - * Returns 0 if no entry was found, 1 otherwise. + * Returns 0 if entry was found, -1 otherwise. * * Do a lookup in the map trying to find an integer key using the string - * value.

[libvirt] [PATCH] Provide a helper method virDomainLiveHelperMethod
by Lei Li 09 Dec '11

09 Dec '11

This chunk of code below repeated in several functions, factor it into a helper method virDomainLiveHelperMethod to eliminate duplicated code based on Eric and Adam's suggestion. I have tested it for all the relevant APIs changed. isActive = virDomainObjIsActive(vm); if (flags == VIR_DOMAIN_AFFECT_CURRENT) { if (isActive) flags = VIR_DOMAIN_AFFECT_LIVE; else flags = VIR_DOMAIN_AFFECT_CONFIG; } if (!isActive && (flags & VIR_DOMAIN_AFFECT_LIVE)) { qemuReportError(VIR_ERR_OPERATION_INVALID, "%s", _("domain is not running")); goto endjob; } if (flags & VIR_DOMAIN_AFFECT_CONFIG) { if (!vm->persistent) { qemuReportError(VIR_ERR_OPERATION_INVALID, "%s", _("cannot change persistent config of a transient domain")); goto endjob; } if (!(persistentDef = virDomainObjGetPersistentDef(driver->caps, vm))) goto endjob; } Signed-off-by: Lei Li <lilei(a)linux.vnet.ibm.com> --- src/conf/domain_conf.c | 47 ++++++++ src/conf/domain_conf.h | 7 + src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 288 ++++------------------------------------------ 4 files changed, 77 insertions(+), 266 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 75e51a0..12ea12d 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -1670,6 +1670,53 @@ virDomainObjGetPersistentDef(virCapsPtr caps, } /* + * Helper method for --current --live --config option, and check with + * whether domain is active or can get persistent domain configuration. + * + * Return 0 if success, also change the flags and get the persistent + * domain configuration if needed.

[libvirt] [PATCH 1/2] nwfilter: Pass the VM's UUID into the nwfilter subsystem
by Stefan Berger 09 Dec '11

09 Dec '11

A preparatory patch for DHCP snooping where we want to be able to differentiate between a VM's interface using the tuple of <VM UUID, Interface MAC address>. We assume that MAC addresses could possibly be re-used between different networks (VLANs) thus do not only want to rely on the MAC address to identify an interface. At the current 'final destination' in virNWFilterInstantiate I am leaving the vmuuid parameter as ATTRIBUTE_UNUSED until the DHCP snooping patches arrive. (we may not post the DHCP snooping patches for 0.9.8, though) Mostly this is a pretty trivial patch. On the lowest layers, in lxc_driver and uml_conf, I am passing the virDomainDefPtr around until I am passing only the VM's uuid into the NWFilter calls. --- src/conf/domain_nwfilter.c | 3 ++- src/conf/domain_nwfilter.h | 2 ++ src/lxc/lxc_driver.c | 5 ++++- src/nwfilter/nwfilter_driver.c | 6 ++++-- src/nwfilter/nwfilter_gentech_driver.c | 27 +++++++++++++++++++-------- src/nwfilter/nwfilter_gentech_driver.h | 5 ++++- src/nwfilter/nwfilter_learnipaddr.c | 3 ++- src/qemu/qemu_command.c | 2 +- src/qemu/qemu_process.c | 2 +- src/uml/uml_conf.c | 11 +++++++---- 10 files changed, 46 insertions(+), 20 deletions(-) Index: libvirt-acl/src/nwfilter/nwfilter_driver.c =================================================================== --- libvirt-acl.orig/src/nwfilter/nwfilter_driver.c +++ libvirt-acl/src/nwfilter/nwfilter_driver.c @@ -443,8 +443,10 @@ cleanup: static int nwfilterInstantiateFilter(virConnectPtr conn, - virDomainNetDefPtr net) { - return virNWFilterInstantiateFilter(conn, net);

[libvirt] [PATCH] spec: fix logic bug in deciding to turn on cgconfig
by Eric Blake 08 Dec '11

08 Dec '11

https://bugzilla.redhat.com/show_bug.cgi?id=738725 Commit ecd8725 tried to silence a spurious warning on the initial libvirt install, and commit ba6cbb1 tried to fix up the logic to the correct Fedora version, but the warning was still present due to a logic bug: since %{fedora} and %{rhel} are never simulatanously set, then 0%{rhel} <= 6 made the %if always true. Checking for minimum versions (via >=) is okay, but checking for maximum versions (via <=) requires a prerequisite test that the platform being tested is non-zero. Also fix a bogus setting of with_libxl (although we previously hard-code with_libxl to 0 for rhel earlier in the file, so this was not as severe a bug). * libvirt.spec.in (with_cgconfig): Don't enable cgconfig on F16. --- How embarrassing that I've botched this patch twice; I didn't notice the botch because 'yum reinstall libvirt' is not an initial install, so it didn't trigger the scriptlet in question.

Hi Please accept the following patch to the rpm spec file. It allows me to enable specific options (like openvz) at the build comand line, even if they have been disabled by OS feature selection. eg for an openvz build on centos 6 rpmbuild -bb \ --define 'rhel 6' \ --without dtrace \ --without sanlock \ --without netcf \ --with openvz \ libvirt.spec Regards Chris (Not subscribed to the mailing list)

[libvirt] virDomainBlockJobAbort and block_job_cancel
by Stefan Hajnoczi 08 Dec '11

08 Dec '11

Block job cancellation waits until the job has been cancelled before returning. This allows clients to know that the operation has been cancelled successfully. Unfortunately, these semantics are not really possible with today's QEMU and libvirt code. A command that waits for block I/O completion may wait for many minutes. During this time the monitor is unavailable. While the QMP protocol may in theory support multiple in-flight commands, both QEMU and libvirt's implemenations are geared towards one command at a time. So in practice a hung cancellation command would make the monitor unavailable - we need to avoid this. This means block_job_cancel cannot wait until the job is cancelled or it risks hanging the monitor if there is a block I/O timeout. We need a solution that reflects this in QEMU and libvirt, here is what I propose: block_job_cancel returns immediately upon marking the job cancelled. The job may still be finishing block I/O but will cancel itself at some point in the future. When the job actually completes it raises the new BLOCK_JOB_CANCELLED event. This means that virDomainBlockJobAbort() returns to the client without a guarantee that the job has completed. If the client enumerates jobs it may still see a job that has not finished cancelling. The client must register a handler for the BLOCK_JOB_CANCELLED event if it wants to know when the job really goes away. The BLOCK_JOB_CANCELLED event has the same fields as the BLOCK_JOB_COMPLETED event, except it lacks the optional "error" message field. The impact on clients is that they need to add a BLOCK_JOB_CANCELLED handler if they really want to wait. Most clients today (not many exist) will be fine without waiting for cancellation. Any objections or thoughts on this? Stefan

[libvirt] [PATCH 2/2] nwfilter: Pass the VM operation type into the nwfilter subsystem
by Stefan Berger 08 Dec '11

08 Dec '11

Another preparatory patch for DHCP snooping where we want to be able to differentiate between a VM start/interface attach and other operations like VM resume and libvirtd restart so that upon VM start we can internally discard all DHCP leases that may still be active for a VM's interface identified by its MAC address (and the VM's UUID). This then helps to prevent installation of filters with IP addresses from a previous run of the VM upon for example a libvird restart or a 'kill -SIGHUP': Pass the VM operation into the nwfilter subsystem. Also this parameter currently is an ATTRIBUTE_UNUSED in 'virNWFilterInstantiate' until the DHCP snooping patches make use of it. I am 'abusing' the enum type originally introduced for 802.1Qb{g|h} to determine what type of operation is being used. Introducing another type probably doesn't make much sense but maybe renaming this enum type to something like 'virVMOperation' would? --- src/conf/domain_nwfilter.c | 3 ++- src/conf/domain_nwfilter.h | 2 ++ src/lxc/lxc_driver.c | 10 ++++++++-- src/nwfilter/nwfilter_driver.c | 3 ++- src/nwfilter/nwfilter_gentech_driver.c | 15 +++++++++++---- src/nwfilter/nwfilter_gentech_driver.h | 1 + src/qemu/qemu_command.c | 8 +++++--- src/qemu/qemu_command.h | 1 + src/qemu/qemu_hotplug.c | 4 +++- src/qemu/qemu_process.c | 7 +++++-- src/uml/uml_conf.c | 14 +++++++++----- src/uml/uml_conf.h | 3 ++- src/uml/uml_driver.c | 3 ++- 13 files changed, 53 insertions(+), 21 deletions(-) Index: libvirt-acl/src/conf/domain_nwfilter.c =================================================================== --- libvirt-acl.orig/src/conf/domain_nwfilter.c +++ libvirt-acl/src/conf/domain_nwfilter.c @@ -38,9 +38,10 @@ virDomainConfNWFilterRegister(virDomainC int virDomainConfNWFilterInstantiate(virConnectPtr conn, const unsigned char *vmuuid, + enum virNetDevVPortProfileOp vmOp, virDomainNetDefPtr net) { if (nwfilterDriver != NULL) - return nwfilterDriver->instantiateFilter(conn, vmuuid, net);

[libvirt] [RFC v5 PATCH 0/5] PowerPC : Extend Libvirt for PowerPC architecture
by Prerna Saxena 08 Dec '11

08 Dec '11

Libvirt continues to be the key interface to configure and manage the KVM guest instances on x86. This patch set is an effort to enable libvirt to support KVM guest configuration and management on Power Book3S machines. Based on community discussion around the earlier version, this patch series augments the present 'kvm' driver to support PowerPC-KVM based guests. With the CPU driver for PowerPC already merged, this patch series adds on clean-ups, and some test cases as suggested. This series mostly focuses on cleanup and addition of testcases for base- powerpc patches. The patches for enabling spapr-vio based addressing would be sent out shortly, with the right domain schema additions. Series description: ------------------- Patch 1/5 : Use sysfs to decipher cpu topology information. Patch 2/5 : Modify the tests/nodeinfotest.c to use sysfs in addition to proc/cpuinfo. Patch 3/5 : Add support for ppc64 qemu Patch 4/5 : Clean up qemuBuildCommandLine to remove x86-specific assumptions. Patch 5/5 : Add ppc64 specific definitions to domain.rng Changelog: ---------- ** v1->v2 : * Patches 1,2,3 unchanged ; The hacks in Patch 4 of v1 replaced by a new patch to neatly select arch-specific features. ** v2->v3 : * Patches 1,2,3 have minor cleanups ; Patch 4 no longer has an arch-specific handler routine. It is now replaced by a much simpler patch that merely removes x86/pc-specific assumptions from libvirt. Patch 5 is a new addition from Michael Ellerman that adds a new device-tree based addressing mechanism for the 'pseries' guest. ** v3->v4 : * Patch 1 has minor cleanups, Patch 2 is a new addition that introduces test cases for patch 1. Patch 3,4 also have minor cleanups Patch 5 is a new addition, it contains ppc64 specific definitions to domain.rng ** v4->v5 : * Patch 1 fixes some issues that were causing testcase (patch 2) to fail. Patch 2 has minor cleanups. Patch 3 unchanged. Patch 4 has a whitespace cleanup. Patch 5 is a subset of the original patch, it contains ppc64 specific additions to domain.rng -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India

[libvirt] Interface pools and passthrough mode (issue to discuss)
by Shradha Shah 08 Dec '11

08 Dec '11

Hello All, While working on my patches I came across an issue which I would like to discuss with everybody. The definition of passthrough mode in the Network XML Format document says that, in passthrough mode each physical interface can only be in use by a single guest interface at a time. Consider the scenario where we a single KVM host: We can define 2 network configurations, one that uses vepa and other that uses passthrough mode with the same interface pool. # virsh net-define vepa_network.xml # virsh net-define passthrough-network.xml Examples: <network> <name>vepa-network</name> <uuid>81ff9090-c91e-6742-64da-4a736edb9a8f</uuid> <forward mode="vepa"> <interface dev="eth10"/> <interface dev="eth11"/> <interface dev="eth12"/> </forward> </network> <network> <name>passthrough-network</name> <uuid>81ff9090-c91e-6742-64da-4a736edb9a88</uuid> <forward mode="passthrough"> <interface dev="eth10"/> <interface dev="eth11"/> <interface dev="eth12"/> </forward> </network> Suppose we use the vepa-network for guest1 and passthrough network for guest2. Examples: Guest 1: (snippet of xml) <interface type='network'> <source network='vepa-network'/> <mac address='00:50:56:0e:86:3b'/> <actual type='direct'> <source mode='vepa'/> </actual> </interface> Guest2: (snippet of xml) <interface type='network'> <source network='passthrough-network'/> <mac address='00:50:56:0e:86:4b'/> <actual type='direct'> <source mode='passthrough'/> </actual> </interface> # virsh define guest1.xml # virsh define guest2.xml # virsh start guest1 # virsh start guest2 Since the virNetworkDef is different for the two network configs, how does libvirt keep track of the interfaces in use at this point? Wouldn't libvirt use the first free interface in both cases which will be eth10 since the usageCount will be zero in both cases start of day? Many Thanks, Regards, Shradha Shah

[libvirt] [PATCH 1/2] maint: use common xml quoting style
by Eric Blake 08 Dec '11

08 Dec '11

According to the official XML specification [1], attributes can be specified with either ' or " (where the difference is that you can use '"' or '"' but must use """, and conversely for "'" or "'" vs. '''). But our code generation in src/conf prefers to output the '' notation, as it is easier to write C string literals for that style. Using a consistent style throughout libvirt will make it easier for users to copy-and-paste without wondering why we switch quoting styles mid-stream.

[libvirt] [PATCH 0/6] Add new command domiftune
by Hu Tao 08 Dec '11

08 Dec '11

This series adds a new command domiftune to get/set parameters of domain's network interfaces. Supported parameters are bandwidth settings. Currently the network interface bandwidth can only be set: - in domain's xml before the domain is up - when attaching an interface by attach-interface With this series, users can change network interface bandwidth settings using virsh, whether the domain is running or not. Hu Tao (6): Add API virDomain{S,G}etInterfaceParameters virDomain{S,G}etInterfaceParameters: the main entry points Add virDomain{S,G}etInterfaceparameters support to the remote driver Add virDomain{S,G}etInterfaceParameters support to qemu driver Enable the virDomain{S,G}etInterfaceParameters in virsh Add document for the new command domiftune daemon/remote.c | 64 ++++++ include/libvirt/libvirt.h.in | 50 +++++ python/generator.py | 2 + src/driver.h | 12 ++ src/libvirt.c | 118 ++++++++++++ src/libvirt_public.syms | 6 + src/qemu/qemu_driver.c | 434 ++++++++++++++++++++++++++++++++++++++++++ src/remote/remote_driver.c | 52 +++++ src/remote/remote_protocol.x | 28 +++- src/remote_protocol-structs | 24 +++ tools/virsh.c | 227 ++++++++++++++++++++++ tools/virsh.pod | 21 ++ 12 files changed, 1037 insertions(+), 1 deletions(-) -- 1.7.3.1

[libvirt] Start of freeze for libvirt-0.9.8 and availability of rc1
by Daniel Veillard 07 Dec '11

07 Dec '11

We are now entering the freeze for libvirt-0.9.8 . For portability sake I think adding more support for PPC machines should still be allowed for a few days, as long as it's not impacting too much of the common code. I have made a release candidate 1 tarball (and associated rpms) at ftp://libvirt.org/libvirt/libvirt-0.9.8-rc1.tar.gz and the git tree is tagged. I think I will make an rc2 on Mon or Thu and then try to make the release around Thursday next week if things looks good. Please give it a try ! thanks in advance, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH] npiv: Auto-generate WWNs if it's not specified
by Osier Yang 07 Dec '11

07 Dec '11

To not change the old API behavior (if no WWNs is specified, error is throwed and the device creation quits), this patch introduce an new flag (VIR_NODE_DEVICE_CREATE_XML_GENERATE_WWN), which indicates the WWNs will be generated automatically by libvirt if they are not specified, and it's ignored if the the WWNs are specified. The auto-generated WWN comply with the new addressing schema of WWN: <quote> the first nibble is either hex 5 or 6 followed by a 3-byte vendor identifier and 36 bits for a vendor-specified serial number. </quote> We choose hex 5 for the first nibble. And use Qumranet's OUI (00:1A:4A) as the 3-byte vendor indentifier. The last 36 bits are auto-generated.

Hi, As part of a research project for the HES-SO (/http://www.hes-so.ch/), I produced a document on the operation of libvirt and implementation of a libvirt cloning function to ESXi. Currently this document is available in French (/http://www.tdeig.ch/kvm/Libvirt.pdf/). If anyone is interestedin, I can translate it into English. Your remarks and comments are welcome. Best regards, Penas Cédric -- _Cédric Penas Assistant HES Laboratoire de Transmission de Données *hepia* Rue de la Prairie 4 CH-1202 Genève cedric.penas(a)hesge.ch <mailto:cedric.penas@hesge.ch> www.hesge.ch/hepia <http://www.hesge.ch/hepia> Tél. +41 (0)22 546 25 47

[libvirt] KVM Call Agenda for 12/6 (Tuesday) @ 10am US/Eastern
by Anthony Liguori 07 Dec '11

07 Dec '11

Hi, I'd like to propose that we discuss guest agent convergence in our next KVM call. I've CC'd folks from oVirt and libvirt to join the discussion. I think we should probably attempt to have some structure to the discussion. I would suggest: 1. A short introduction to each of the guest agents, what guests they support, and what verbs they support. 2. A short description of key requirements from each party (oVirt, libvirt, QEMU) for a guest agent 3. An open discussion about possible ways to collaborate/converge. Regards, Anthony Liguori

[libvirt] [PATCH v2 0/2] Guest NUMA topology support
by Bharata B Rao 07 Dec '11

07 Dec '11

Hi, This is v2 of the patchset that adds support for specifying NUMA topology for guests. <cpu> ... <topology sockets='2' cores='4' threads='2'/> <numa> <cell cpus='0-7' mems='512000'/> <cell cpus='8-15' mems='512000'/> </numa> ... </cpu> This change allows libvirt to generate -numa options for QEMU/KVM. This patchset passes all tests except daemon-conf test. Changes for v2 -------------- - Renamed mems to memory in NUMA cell specification. - Make both cpus= and memory= mandatory in a NUMA cell. - Reuse cpuset and memoryKB definitions for cpus and memory. - Fix a bug in reading memory=. - Correct error handling for usages of virXMLPropString. - Support virsh dumpxml. - Fix XML in domaincommon.rng so that <numa> works correctly for both <cpu> ... <cpu> as well as <cpu match="..."> ... <cpu> - Don't use virBufferTruncate. - Modifiy qemuxml2argv test cases for s/mems/memory change. - Use virBufferLit wherever possible. - Now qemuBuildNumaCPUArgStr can't fail, hence doesn't need return val. - Pass memory in MB to qemu. v1 - https://www.redhat.com/archives/libvir-list/2011-November/msg00247.html v0 - https://www.redhat.com/archives/libvir-list/2011-October/msg00025.html RFC - http://permalink.gmane.org/gmane.comp.emulators.libvirt/44626 Regards, Bharata.

[libvirt] [PATCH] security: don't try to restore label on NFS if label failed
by Eric Blake 07 Dec '11

07 Dec '11

I noticed that the logs contained messages like this: 2011-12-05 23:32:40.382+0000: 26569: warning : SELinuxRestoreSecurityFileLabel:533 : cannot lookup default selinux label for /nfs/libvirt/images/dom.img for all my domain images living on NFS. But if we would just remember that on domain creation that we were unable to set a SELinux label (due to NFSv3 lacking labels, or NFSv4 not being configured to expose attributes), then we could avoid wasting the time trying to clear the label on domain shutdown. This in turn is one less point of NFS failure, especially since there have been documented cases of virDomainDestroy hanging during an attempted operation on a failed NFS connection. I tested that this works over libvirtd restart for <disk> images; it cannot work for other labeled file types unless we also enhance those in-memory representations to track whether a label is in force. * src/conf/domain_conf.h (_virDomainDiskDef): Add member. * src/conf/domain_conf.c (virDomainDiskDefParseXML): Parse it. (virDomainDiskDefFormat): Output it. * src/security/security_selinux.c (SELinuxSetFilecon): Move guts... (SELinuxSetFileconHelper): ...to new function. (SELinuxSetFileconOptional): New function. (SELinuxSetSecurityFileLabel): Remember if labeling failed. (SELinuxRestoreSecurityImageLabelInt): Skip relabeling on NFS. --- This is an attempt to address the primary symptom (but NOT the root cause) of https://bugzilla.redhat.com/746666, since that is a documented case of a hang during the label restoration that would be skipped had we remembered that no label was applied at domain start. A full solution to that problem will involve much more invasive lock refactoring, and probably the creation of one thread per VM rather than the current approach of reusing RPC threads for VM operations, where the per-VM thread is used for any operation that might hang on NFS. https://www.redhat.com/archives/libvir-list/2011-November/msg00267.html src/conf/domain_conf.c | 5 +++++ src/conf/domain_conf.h | 1 + src/security/security_selinux.c | 39 ++++++++++++++++++++++++++++----------- 3 files changed, 34 insertions(+), 11 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 75e51a0..38d24e0 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -2774,6 +2774,9 @@ virDomainDiskDefParseXML(virCapsPtr caps, } else if (xmlStrEqual(cur->name, BAD_CAST "transient")) { def->transient = 1; } else if ((flags & VIR_DOMAIN_XML_INTERNAL_STATUS) && + xmlStrEqual(cur->name, BAD_CAST "nolabel")) { + def->noSecurityLabel = 1; + } else if ((flags & VIR_DOMAIN_XML_INTERNAL_STATUS) && xmlStrEqual(cur->name, BAD_CAST "state")) { /* Legacy back-compat.

For our forthcomming release of UCS-3.0 we really wanted to switch from Xend to xl, but be had to switch back to using Xend, because libvirt still lacks some important features like migration; see <http://libvirt.org/hvsupport.html> for a comparison matrix.

[libvirt] [PATCH 0/5] Interface pools and passthrough mode
by Shradha Shah 06 Dec '11

06 Dec '11

Interface Pools and Passthrough mode: Current Method: The passthrough mode uses a macvtap a direct connection to connect each guest to the network. The physical interface to be used is picked from among those listed in <interface> sub elements of the <forward> element. The current specification for <forward> extends to allow 0 or more <interface> sub-elements: Example: <forward mode='passthrough' dev='eth10'/> <interface dev='eth10'/> <interface dev='eth12'/> <interface dev='eth18'/> <interface dev='eth20'/> </forward> However with an ethernet card with 64 VF's or more, the above method gets tedious on the system. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. Proposed Method: The 5 patches provided along with this introductory e-mail i) Introduce a structure to store the state of all the virtual functions attached to each physical function ii) Find a free virtual function given the physical function. The forward specification will hence only mention the physical function as the interface sub element: Example: <forward mode='passthrough' dev='eth2'/> <interface dev='eth2'/> </forward> Shradha Shah (5): Moving the declaration of _pciDevice and _pciDeviceList to pci.h Added function pciSysfsFile to enable access to the PCI SYSFS files. Adding functions virNetDevGetVirtualFunctions and virNetDevGetNetName virNetDevGetVirtualFunctions: Gets the BDF of all the Virtual Functions given a physical function virNetDevGetNetName: Gets the interface name of the PCI Device. Addition of a new device structure to store the state of a Virtual Function Modifications to the Physical Device Structure to store state of its Virtual Functions If a system has 64 or more VF's, it is quite tedious to mention each VF in the interface pool. The following modification find a Free VF given a Physical Function when mode=passthrough. We also save the state of each VF. Hence modifications to networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice were required. The following patch does just that. src/conf/network_conf.c | 19 ++++- src/conf/network_conf.h | 10 ++ src/network/bridge_driver.c | 208 +++++++++++++++++++++++++++++++++++++------ src/util/pci.c | 52 ++++------- src/util/pci.h | 36 ++++++++ src/util/virnetdev.c | 89 ++++++++++++++++++ src/util/virnetdev.h | 10 ++ 7 files changed, 359 insertions(+), 65 deletions(-) -- 1.7.4.4

[libvirt] Group for accessing one/all VM graphics and not virsh
by Reeted 06 Dec '11

06 Dec '11

Hello libvirt people, is there a (preferably simple) way in Linux to allow a certain set of users to be able to do: virt-viewer --connect qemu+ssh://username@virthost/system vmname for connecting to virt-viewer BUT without letting them do all the other things that can be done with virsh? I know that if I add them to the libvirtd and kvm groups, they will be able to connect with virt-viewer to any virtual machine AND ALSO do any virsh command on any virtual machine. This is too much permission. I can accept the first part (a way to allow a group of user to connect with virt-viewer to all the virtual machines of the host) since more restriction can be enforced by using VNC passwords... But if they are also able to do anything in virsh that's too much. I am using only qemu and kvm in libvirt. Thank you R.
