[libvirt] [PATCH] add a default event handle, to passthough the new events come from qemu

by shaohef＠linux.vnet.ibm.com

From: Shaohe 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.

[libvirt] [PATCH RESEND] qemu: Do not free the device from activePciHostdevs if it's in use

As pciResetDevice and pciReattachDevice won't be called for the device anymore. This is sensiable as we already reported error when preparing the device if it's active. Blindly trying to pciResetDevice & pciReattachDevice on the device and getting an error is just redundant. --- src/qemu/qemu_hostdev.c | 4 +++- 1 files changed, 3 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_hostdev.c b/src/qemu/qemu_hostdev.c index 9137388..60401f0 100644 --- a/src/qemu/qemu_hostdev.c +++ b/src/qemu/qemu_hostdev.c @@ -414,8 +414,10 @@ void qemuDomainReAttachHostdevDevices(struct qemud_driver *driver, */ activeDev = pciDeviceListFind(driver->activePciHostdevs, dev); if (activeDev && - STRNEQ_NULLABLE(name, pciDeviceGetUsedBy(activeDev))) + STRNEQ_NULLABLE(name, pciDeviceGetUsedBy(activeDev))) { + pciDeviceListSteal(pcidevs, dev); continue; + } /* pciDeviceListFree() will take care of freeing the dev. */ pciDeviceListSteal(driver->activePciHostdevs, dev); -- 1.7.7.3

[libvirt] [PATCH 0/4] Add support for QEMU guest agent control

by Daniel P. Berrange

The QEMU guest agent "/usr/bin/qemu-ga" has some handy functions for controlling the guest, not least, shutdown/reboot and filesystem freeze/thaw. In Fedora 15/16 the semantics of the ACPI power button have been changed to suspend-to-RAM which breaks our current shutdown implementation. By adding support for the agent we gain a more predictable way to shutdown / reboot guests. NB: the code currently has the same "flaw" as the monitor, in so much as we wait forever for a guest agent reply. We need to add a timeout ability to the agent code

[libvirt] (no subject)

by Osier Yang

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] nwfilter: cleanup return codes in nwfilter subsystem

by Stefan Berger

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 1/2] nwfilter: Pass the VM's UUID into the nwfilter subsystem

by Stefan Berger

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] RPM spec file patch

by Chris Picton

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

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
