[libvirt] [PATCH RFC] helper of copy-storage-* features
by liguang 22 Oct '12

22 Oct '12

help to create disk images copy-storage-* required, try to do non-shared migration without bothering to create disk images at target by hand. consider this situation: 1. non-shared migration virsh migrate --copy-storage-all ... 2. migration fails 3. create disk images required qemu-img create ... 4 migration run smoothly so, try do remove step 2, 3, 4 this kind of use had been discussed before, http://www.redhat.com/archives/libvir-list/2011-December/msg00451.html maybe there're some flaws: - It did not handle more about complete situations suggested by Daniel P. Berrange, https://www.redhat.com/archives/libvir-list/2012-October/msg00407.html but may try to take care of them later. so, now only normal disk image files be handled. - for creation of disk images, size was setting as 0xffffffff boldly, hope it can consolidate qemu, haven't constructed a comfortable idea to solve it.

[libvirt] [PATCH 0/2] qemu: Check if qemu is VNC capable
by Doug Goldstein 22 Oct '12

22 Oct '12

This is the initial series where I'll be exposing the graphical support that QEMU has via capabilities but I'm breaking it up to get in as much as possible based on my available time. This initial set adds checks to see that your QEMU binary has VNC support instead of assuming that it does. A large Gentoo user apparently just uses SPICE and as a result we now provide the ability to install QEMU without VNC. While this is not a recommended configuration its certainly valid and libvirt should not assume it exists.

[libvirt] [PATCH] migrate: v2: use VIR_DOMAIN_XML_MIGRATABLE when available
by Ján Tomko 22 Oct '12

22 Oct '12

In v2 migration protocol, XML is obtained by calling domainGetXMLDesc. This includes the default USB controller in XML, which breaks migration to older libvirt (before 0.9.2). Commit 409b5f549530e7b3a33f4505f2cad2e26896107c qemu: Emit compatible XML when migrating a domain only fixed this for v3 migration. This patch uses the new VIR_DOMAIN_XML_MIGRATABLE flag (detected by VIR_DRV_FEATURE_XML_MIGRATABLE) to obtain XML without the default controller, enabling backward v2 migration. --- src/libvirt.c | 13 ++++++++++--- src/libvirt_internal.h | 5 +++++ src/qemu/qemu_driver.c | 1 + 3 files changed, 16 insertions(+), 3 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index e3ddf27..f6f5b91 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -4620,6 +4620,7 @@ virDomainMigrateVersion2 (virDomainPtr domain, int cookielen = 0, ret; virDomainInfo info; virErrorPtr orig_err = NULL; + unsigned int getxml_flags = 0; int cancelled; VIR_DOMAIN_DEBUG(domain, "dconn=%p, flags=%lx, dname=%s, uri=%s, bandwidth=%lu", @@ -4646,9 +4647,15 @@ virDomainMigrateVersion2 (virDomainPtr domain, virDispatchError(domain->conn); return NULL; } - dom_xml = domain->conn->driver->domainGetXMLDesc(domain, - VIR_DOMAIN_XML_SECURE | - VIR_DOMAIN_XML_UPDATE_CPU); + + if (VIR_DRV_SUPPORTS_FEATURE(domain->conn->driver, domain->conn, + VIR_DRV_FEATURE_XML_MIGRATABLE)) { + getxml_flags |= VIR_DOMAIN_XML_MIGRATABLE; + } else { + getxml_flags |= VIR_DOMAIN_XML_SECURE | VIR_DOMAIN_XML_UPDATE_CPU; + } + + dom_xml = domain->conn->driver->domainGetXMLDesc(domain, getxml_flags); if (!dom_xml) return NULL; diff --git a/src/libvirt_internal.h b/src/libvirt_internal.h index 23e7153..71483e4 100644 --- a/src/libvirt_internal.h +++ b/src/libvirt_internal.h @@ -95,6 +95,11 @@ enum { * messages). */ VIR_DRV_FEATURE_PROGRAM_KEEPALIVE = 10, + + /* + * Support for VIR_DOMAIN_XML_MIGRATABLE flag in domainGetXMLDesc + */ + VIR_DRV_FEATURE_XML_MIGRATABLE = 11, }; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 76730c6..0c35dad 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1130,6 +1130,7 @@ qemudSupportsFeature (virConnectPtr conn ATTRIBUTE_UNUSED, int feature) case VIR_DRV_FEATURE_MIGRATE_CHANGE_PROTECTION: case VIR_DRV_FEATURE_FD_PASSING: case VIR_DRV_FEATURE_TYPED_PARAM_STRING: + case VIR_DRV_FEATURE_XML_MIGRATABLE: return 1; default: return 0; -- 1.7.8.6

[libvirt] [PATCH] network: always create dnsmasq hosts and addnhosts files, even if empty
by Laine Stump 22 Oct '12

22 Oct '12

This fixes the problem reported in: https://bugzilla.redhat.com/show_bug.cgi?id=868389 Previously, the dnsmasq hosts file (used for static dhcp entries, and addnhosts file (used for additional dns host entries) were only created/referenced on the dnsmasq commandline if there was something to put in them at the time the network was started. Once we can update a network definition while it's active (which is now possible with virNetworkUpdate), this is no longer a valid strategy - if there were 0 dhcp static hosts (resulting in no reference to the hosts file on the commandline), then one was later added, the commandline wouldn't have linked dnsmasq up to the file, so even though we create it, dnsmasq doesn't pay any attention. The solution is to just always create these files and reference them on the dnsmasq commandline (almost always, anyway). That way dnsmasq can notice when a new entry is added at runtime (a SIGHUP is sent to dnsmasq by virNetworkUdpate whenever a host entry is added or removed) The exception to this is that the dhcp static hosts file isn't created if there are no lease ranges *and* no static hosts. This is because in this case dnsmasq won't be setup to listen for dhcp requests anyway - in that case, if the count of dhcp hosts goes from 0 to 1, dnsmasq will need to be restarted anyway (to get it listening on the dhcp port).

[libvirt] [PATCH] daemon: Avoid 'Could not find keytab file' in syslog

On F17 at least, every time libvirtd starts we get this in syslog: libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory This comes from cyrus-sasl, and happens regardless of whether the gssapi plugin is requested, which is what actually uses /etc/libvirt/krb5.tab. While cyrus-sasl shouldn't complain, we can easily make it shut up by commenting out the keytab value by default.

[libvirt] 0.10.2 virtualport profileid (802.1Qbh) malformed
by Tom Lanyon 21 Oct '12

21 Oct '12

Hi, I've just upgraded a test libvirtd host to 0.10.2 from 0.9.4 to be able to make use of the new 'virsh net-update add portgroup' live updates, however can't get my private/802.1Qbh interfaces working at all after the upgrade. Trying to start an existing domain or install a new domain after the upgrade gives: "ERROR internal error corrupted profileid string" and a corresponding error in the libvirtd log: "error : virNetDevVPortProfileMerge:381 : internal error corrupted profileid string" I've tried all sorts of profileid combinations and tried defining the virtualport in the domain instead of in the network, to no avail. The source indicates this is to do with a malformed (not null terminated) profile id when merging the port profile. Why would this be happening? Any hints how to debug it? My example network definition: <network> <name>testnet</name> <uuid>76d32a2d-8433-6873-9c15-cdae30e7a632</uuid> <forward dev='eth1' mode='private'> <interface dev='eth1'/> <interface dev='eth2'/> <interface dev='eth3'/> ... </forward> <portgroup name='server1' default='yes'> <virtualport type='802.1Qbh'> <parameters profileid='profile-server1'/> </virtualport> </portgroup> <portgroup name='server2'> <virtualport type='802.1Qbh'> <parameters profileid='profile-server2'/> </virtualport> </portgroup> <portgroup name='server3'> <virtualport type='802.1Qbh'> <parameters profileid='profile-server3'/> </virtualport> </portgroup> </network> and a domain definition which throws an error on start-up: <interface type='network'> <mac address='52:54:00:d1:94:5f'/> <source network='testnet' portgroup='server1'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> Tom

[libvirt] [PATCH] network: free/null newDef if network fails to start
by Laine Stump 19 Oct '12

19 Oct '12

https://bugzilla.redhat.com/show_bug.cgi?id=866364 pointed out a crash due to virNetworkObjAssignDef free'ing network->newDef without NULLing it afterward. A fix for this is in upstream commit b7e9202401ebaa039b8f05acdefda8c24081537a. While the NULLing of newDef was a legitimate fix, newDef should have already been empty (NULL) anyway (as indicated in the comment that was deleted by that commit). The reason that newDef had a non-NULL value (i.e. the root cause) was that networkStartNetwork() had failed after populating network->newDef, but then neglected to free/NULL newDef in the cleanup. (A bit of background here: network->newDef should contain the persistent config of a network when a network is active (and of course only when it is persisten), and NULL at all other times. There is also a network->def which should contain the persistent definition of the network when it is inactive, and the current live state at all other times. The idea is that you can make changes to network->newDef which will take effect the next time the network is restarted, but won't mess with the current state of the network (virDomainObj has a similar pair of virDomainDefs that behave in the same fashion). Personally I think there should be a network->live and network->config, and the location of the persistent config should *always* be in network->config, but that's for a later cleanup). Since I love things to be symmetric, I created a new function called virNetworkObjUnsetDefTransient(), which reverses the effects of virNetworkObjSetDefTransient(). I don't really like the name of the new function, but then I also didn't really like the name of the old one either (it's just named that way to match a similar function in the domain conf code). --- src/conf/network_conf.c | 14 ++++++++++++++ src/conf/network_conf.h | 1 + src/libvirt_private.syms | 1 + src/network/bridge_driver.c | 12 ++++-------- 4 files changed, 20 insertions(+), 8 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 0f7470d..2f9ad2e 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -352,6 +352,20 @@ virNetworkObjSetDefTransient(virNetworkObjPtr network, bool live) return network->newDef ? 0 : -1; } +/* virNetworkObjUnsetDefTransient: + * + * This *undoes* what virNetworkObjSetDefTransient did. + */ +void +virNetworkObjUnsetDefTransient(virNetworkObjPtr network) +{ + if (network->def) { + virNetworkDefFree(network->def); + network->def = network->newDef; + network->newDef = NULL; + } +} + /* * virNetworkObjGetPersistentDef: * @network: network object pointer diff --git a/src/conf/network_conf.h b/src/conf/network_conf.h index 55502fb..4c0c8c1 100644 --- a/src/conf/network_conf.h +++ b/src/conf/network_conf.h @@ -253,6 +253,7 @@ int virNetworkObjAssignDef(virNetworkObjPtr network, const virNetworkDefPtr def, bool live); int virNetworkObjSetDefTransient(virNetworkObjPtr network, bool live); +void virNetworkObjUnsetDefTransient(virNetworkObjPtr network); virNetworkDefPtr virNetworkObjGetPersistentDef(virNetworkObjPtr network); int virNetworkObjReplacePersistentDef(virNetworkObjPtr network, virNetworkDefPtr def); diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 1a0c2f6..fd30024 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -872,6 +872,7 @@ virNetworkObjLock; virNetworkObjReplacePersistentDef; virNetworkObjSetDefTransient; virNetworkObjUnlock; +virNetworkObjUnsetDefTransient; virNetworkObjUpdate; virNetworkRemoveInactive; virNetworkSaveConfig; diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 5578373..fa909a1 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -2327,8 +2327,10 @@ networkStartNetwork(struct network_driver *driver, break; } - if (ret < 0) + if (ret < 0) { + virNetworkObjUnsetDefTransient(network); return ret; + } /* Persist the live configuration now that anything autogenerated * is setup. @@ -2388,13 +2390,7 @@ static int networkShutdownNetwork(struct network_driver *driver, } network->active = 0; - - if (network->newDef) { - virNetworkDefFree(network->def); - network->def = network->newDef; - network->newDef = NULL; - } - + virNetworkObjUnsetDefTransient(network); return ret; } -- 1.7.11.7

19 Oct '12

Commit ba63d8f7d843461f77a8206c1ef9da38388713e5 introduced a bug that makes machines, that don't have either cpuset in <vcpu> or <emulatorpin> specified, fail. Because the function that sets affinity is called without any check, the function must not fail unless there is an error. --- src/qemu/qemu_process.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index e08ec67..b97aaef 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -2029,22 +2029,24 @@ static int qemuProcessSetEmulatorAffinites(virConnectPtr conn, virDomainObjPtr vm) { - virBitmapPtr cpumask; + virBitmapPtr cpumask = NULL; virDomainDefPtr def = vm->def; virNodeInfo nodeinfo; int ret = -1; - if (virNodeGetInfo(conn, &nodeinfo) != 0) - return -1; + if (virNodeGetInfo(conn, &nodeinfo) < 0) + goto cleanup; if (def->cputune.emulatorpin) cpumask = def->cputune.emulatorpin->cpumask; else if (def->cpumask) cpumask = def->cpumask; + + if (cpumask) + ret = virProcessInfoSetAffinity(vm->pid, cpumask); else - goto cleanup; + ret = 0; - ret = virProcessInfoSetAffinity(vm->pid, cpumask); cleanup: return ret; } -- 1.7.12.3

[libvirt] [PATCH] qemu: Set arch to i686 if qemu-system-i386 is found
by Guido Günther 19 Oct '12

19 Oct '12

If we can't probe the architecture from QMP we parse the architecture from the qemu binaries name. This results in the architecture being i386 instead of i686 which then results in QEMU_CAPS_PCI_MULTIBUS being unset which gives a broken qemu command line. This probably didn't show up earlier since most of the time there's also a /usr/bin/qemu around which results in i686 capabilities. --- src/qemu/qemu_capabilities.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 7c391b3..e897f86 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -2055,6 +2055,8 @@ qemuCapsInitHelp(qemuCapsPtr caps) /* For historical compat we use 'itanium' as arch name */ if (STREQ(tmp, "ia64")) tmp = "itanium"; + else if (STREQ(tmp, "i386")) + tmp = "i686"; } else { uname_normalize(&ut); tmp = ut.machine; -- 1.7.10.4

[libvirt] [PATCH v3 4/4] qemu-config: Add new -add-fd command line option
by Corey Bryant 18 Oct '12

18 Oct '12

This option can be used for passing file descriptors on the command line. It mirrors the existing add-fd QMP command which allows an fd to be passed to QEMU via SCM_RIGHTS and added to an fd set. This can be combined with commands such as -drive to link file descriptors in an fd set to a drive: qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file" -add-fd fd=4,set=2,opaque="rdonly:/path/to/file" -drive file=/dev/fdset/2,index=0,media=disk This example adds dups of fds 4 and 5, and the accompanying opaque strings to the fd set with ID=2. qemu_open() already knows how to handle a filename of this format. qemu_open() searches the corresponding fd set for an fd and when it finds a match, QEMU goes on to use a dup of that fd just like it would have used an fd that it opened itself.

[libvirt] [PATCHv2 00/16] qemu block-commit support
by Eric Blake 18 Oct '12

18 Oct '12

I figured I'd better post this now, while I still iron out the remaining kinks in my SELinux handling (but I'm certainly a lot closer, now that I have libvirt actually identifying which files need the temporary SELinux labels). With this, you can now do things like 'virsh blockcommit $dom $disk --top relative_name --shallow' even when the backing chain refers to an absolute backing file name; the QMP command passed to qemu will have the correct absolute names. Patches 1-6: practically unchanged since v1, although not reviewed yet https://www.redhat.com/archives/libvir-list/2012-October/msg00075.html Patches 7-13: new to this series Patches 14-15: minor changes since v1 ACKs; see details in each commit https://www.redhat.com/archives/libvir-list/2012-October/msg00089.html Patch 16: new to this series Also available at: http://repo.or.cz/w/libvirt/ericb.git/shortlog/refs/heads/blockjob git fetch git://repo.or.cz/libvirt/ericb.git blockjob Eric Blake (16): storage: list more file types storage: treat 'aio' like 'raw' at parse time storage: match RNG to supported driver types storage: use enum for default driver type storage: use enum for disk driver type storage: use enum for snapshot driver type storage: don't probe non-files storage: get entire metadata chain in one call storage: don't require caller to pre-allocate metadata struct storage: remember relative names in backing chain storage: make it easier to find file within chain storage: cache backing chain while qemu domain is live storage: use cache to walk backing chain blockjob: manage qemu block-commit monitor command blockjob: wire up online qemu block-commit blockjob: implement shallow commit flag in qemu docs/schemas/domaincommon.rng | 27 +- docs/schemas/domainsnapshot.rng | 2 +- src/conf/capabilities.h | 4 +- src/conf/domain_conf.c | 160 ++++-------- src/conf/domain_conf.h | 8 +- src/conf/snapshot_conf.c | 23 +- src/conf/snapshot_conf.h | 2 +- src/conf/storage_conf.c | 15 +- src/libvirt.c | 2 - src/libvirt_private.syms | 1 + src/libxl/libxl_conf.c | 42 ++-- src/libxl/libxl_driver.c | 6 +- src/qemu/qemu_capabilities.c | 3 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 12 +- src/qemu/qemu_command.c | 18 +- src/qemu/qemu_domain.c | 40 ++- src/qemu/qemu_domain.h | 3 + src/qemu/qemu_driver.c | 236 +++++++++++------ src/qemu/qemu_hotplug.c | 9 +- src/qemu/qemu_monitor.c | 30 +++ src/qemu/qemu_monitor.h | 7 + src/qemu/qemu_monitor_json.c | 34 +++ src/qemu/qemu_monitor_json.h | 7 + src/qemu/qemu_process.c | 23 ++ src/security/security_dac.c | 7 - src/security/security_selinux.c | 11 - src/security/virt-aa-helper.c | 27 +- src/storage/storage_backend_fs.c | 15 +- src/util/storage_file.c | 279 ++++++++++++++++----- src/util/storage_file.h | 43 ++-- src/vbox/vbox_tmpl.c | 6 +- src/xenxs/xen_sxpr.c | 26 +- src/xenxs/xen_xm.c | 28 ++- tests/sexpr2xmldata/sexpr2xml-curmem.xml | 2 +- .../sexpr2xml-disk-block-shareable.xml | 2 +- .../sexpr2xml-disk-drv-blktap-raw.xml | 2 +- .../sexpr2xml-disk-drv-blktap2-raw.xml | 2 +- 38 files changed, 773 insertions(+), 392 deletions(-) -- 1.7.11.7

which frees all allocated memory but doesn't set the passed pointer to NULL. Therefore, we must do it ourselves. This is causing actual libvirtd crash: Basically, when doing 'virsh net-edit' the newDef should be dropped. And the memory is freed, indeed. However, the pointer is not set to NULL but kept instead. And the next duo of calls 'virsh net-start' and 'virsh net-destroy' starts the disaster. The latter one does the same as 'virsh destroy'; it sees that newDef is nonNULL so it replaces def with newDef (which has been freed already as said a few lines above). Therefore any subsequent call accessing def will hit the ground. --- src/conf/network_conf.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 891d48c..0f7470d 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -260,8 +260,9 @@ virNetworkObjAssignDef(virNetworkObjPtr network, return -1; } } else if (!live) { - virNetworkDefFree(network->newDef); /* should be unnecessary */ + virNetworkDefFree(network->newDef); virNetworkDefFree(network->def); + network->newDef = NULL; network->def = def; } else { virReportError(VIR_ERR_OPERATION_INVALID, -- 1.7.8.6

[libvirt] [PATCH] qemu: Always format CPU topology
by Jiri Denemark 18 Oct '12

18 Oct '12

When libvirt cannot find a suitable CPU model for host CPU (easily reproducible by running libvirt in a guest), it would not provide CPU topology in capabilities XML either. Even though CPU topology is known and can be queried by virNodeGetInfo.

[libvirt] [PATCH v3 2/4] monitor: Enable adding an inherited fd to an fd set
by Corey Bryant 18 Oct '12

18 Oct '12

qmp_add_fd() gets an fd that was received over a socket with SCM_RIGHTS and adds it to an fd set. This patch adds support that will enable adding an fd that was inherited on the command line to an fd set. Note: All of the code added to monitor_fdset_add_fd(), with the exception of the error path for non-valid fdset-id, is code motion from qmp_add_fd().

[libvirt] [HELP] QEMU guest agent via ISA serial port, or shutdown hooks?
by Thorsten Glaser 18 Oct '12

18 Oct '12

Hi, http://www.redhat.com/archives/libvir-list/2012-January/msg00629.html added support only for when using the virtio channel to the guest. However, QEMU Guest Agent support is most useful to guests that do not implement ACPI shutdown support; these usually don’t have virtio (especially since I was unable to find a how-to-implement-virtio-in- a-kernel document, otherwise MirBSD might do virtio-rng at least ☺), so the serial transport would be best. The problem is of course the two lines: + if (channel->targetType != VIR_DOMAIN_CHR_CHANNEL_TARGET_TYPE_VIRTIO) + continue; I’ve done a bit of hacking to allow the name attribute in the domain XML for any character device (probably half wrong, but this was just a quick test for me) and commented out these two lines, to see whether qga support on ISA ports is doable. (You probably would want to allow the attribute only on virtio and ISA serial ports, then.)

Currently we query-spice after the main migration has completed before moving to next state. Qemu reports this as boolean (not enclosed within quotes). Therefore it is not correct to use virJSONValueObjectGetString but virJSONValueObjectGetBoolean instead. --- Meanwhile, this is does no harm for now, since we fail to set QEMU_CAPS_SEAMLESS_MIGRATION as we use querying capabilities on the QMP monitor where 'seamless-migration=[on|off]' cmd line option is not advertised.

[libvirt] [PATCH v2 0/3] Implement CPU model driver for PowerPC
by Li Zhang 17 Oct '12

17 Oct '12

CPU model driver is to get host's CPU information and it also provides one mechanism to expose host's CPU information to guests during migration. When migrating one guest from one machine to another machine, it will compare the CPU information. If it is incomptible, it won't start the guest. On x86, it uses CPUID instruction to get information. When migrating the guest, if the CPU defined in guest XML file is incompatible with host CPU, cpu-baseline will find out best features to expose to guest. Refer to [http://berrange.com/posts/2010/02/15 /guest-cpu-model-configuration-in-libvirt-with-qemukvm/]. On PowerPC, it can get CPU version by mfpvr instruction. So, if PVR is different from definition in guest XML file by cpu-compare, it will fail to start guest. The CPU infromation can be got by cpu-baseline. But only CPU vendor and model can be shown, there are no features as x86. So on PowrePC, it assumes that migration only occurs between the machines with the same type CPUs on PowerPC. In this driver, there are definitions of models and PVRs for CPUs supported on PowerPC. The relationship between models and PVRs are as the following: For one specific CPU model, its PVR is unique. And also for one PVR code, the PVR code is also unique. So from the PVR code of CPU data, it's easy to get model and vendor information. It is tested on my Power machine which CPU PVR is Power7_v2.3. * cap.xml has the same definition as the host.

original migration did not aware of offline case, so, try to support offline migration quietly (did not disturb original migration) by pass VIR_MIGRATE_OFFLINE flag to migration APIs if only the domain is really inactive, and migration process will not puzzled by domain offline and exit unexpectedly. these changes did not take care of disk images the domain required, for them could be transferred by other APIs as suggested, then VIR_MIGRATE_OFFLINE should not combined with VIR_MIGRATE_NON_SHARED_*. if you want a persistent migration, you should do "virsh migrate --persistent" youself.

[libvirt] LIBVIRT_DEBUG=1 libvirtd regression
by Cole Robinson 17 Oct '12

17 Oct '12

Hey Dan, This commit changes the behavior of LIBVIRT_DEBUG=1 libvirtd: $ git show 7022b09111d4322d21396a70d58320a9ad773962 commit 7022b09111d4322d21396a70d58320a9ad773962 Author: Daniel P. Berrange <berrange(a)redhat.com> Date: Thu Sep 27 13:13:09 2012 +0100 Automatically enable systemd journal logging Probe to see if the systemd journal is accessible, and if so enable logging to the journal by default, rather than stderr (current default under systemd). It still prints some output to stderr but it's extremely limited compared to before. Surprised me at least, but I didn't dig too deeply for a solution. Thanks, Cole

[libvirt] [PATCH v3 1/4] monitor: Allow add-fd to any specified fd set

16 Oct '12

An update of https://www.redhat.com/archives/libvir-list/2012-August/msg00618.html Mostly this is a rebase to latest GIT. Alot of the questions raised with review last time bogged down on whether the APIs were design in the right way. I think I clarified their intended usage, so hopefully we can do code review this time :-) There are still a few more patches to add on to this - Serialize the tx/rx message queues so we don't loose partially sent/received messages across re-exec() - Make fcntl driver more configurable in its behaviour - Add support for leases based on LVM UUID and SCSI WWN

[libvirt] [RFC][PATCH] change the meaning of vnc port in xml
by Hu Tao 16 Oct '12

16 Oct '12

Now the vnc port in xml file reflects the REAL port hypervisor will listen on for vnc connection. But vnc ports usually start from 5900, it's common to say 0 for 5900, 1 for 5901, and so on. This patch forbids negative vnc port number in xml, and maps port number below 5900 to 5900+port, but no change to those greater than 5900. --- I have no idea whether this behaviour is sane or not. But my vnc client(vinagre) has the same behaviour, i.e., treats port 0 as 5900, 1 as 5901, but 5900 as 5900, 5901 as 5901. src/conf/domain_conf.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 0cea8eb..b3cbc34 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -6423,6 +6423,12 @@ virDomainGraphicsDefParseXML(xmlNodePtr node, if (flags & VIR_DOMAIN_XML_INACTIVE) def->data.vnc.port = 0; def->data.vnc.autoport = 1; + } else if (def->data.vnc.port < 0) { + virReportError(VIR_ERR_XML_ERROR, + _("invalid vnc port %s"), port); + goto error; + } else if (def->data.vnc.port < 5900) { + def->data.vnc.port += 5900; } } else { def->data.vnc.port = 0; -- 1.7.10.2

[libvirt] Problems using netdev_del+netdev_add w/o corresponding device_del+device_add
by Laine Stump 16 Oct '12

16 Oct '12

I am attempting to enhance libvirt's virDomainUpdateDeviceFlags() API to support changing "just about anything" about the host side of a PCI network device without actually detaching the PCI device from the guest. Here is a patch I sent to the libvirt mailing list that I had thought would accomplish this task: https://www.redhat.com/archives/libvir-list/2012-October/msg00546.html I am using qemu-kvm-1.2-0.1.20120806git3e430569.fc17.x86_64 on Fedora 17 for my testing. Since the host side and guest side are created (and deleted) with separate monitor commands ("netdev_(add|del)" vs. "device_(add|del)", we had thought that it would be possible to use netdev_del to disconnect everything from the host side, [*not disconnect the guest side*], then create a new tap device and connect it with netdev_add(). And, actually, the netdev_del+netdev_add sequence does complete without error; unfortunately, no traffic is visible on the tap device (looking from the host with tcpdump). When I modify the patch above to also include the device_del and device_add monitor calls (with a 3 second delay in between to allow for the guest's PCI detach to complete), then the device does work properly. Of course in this case (1) the guest sees the device completely disappear for a period, then reappear, which is more disruption than I want, and (2) because qemu has no asynchronous event to notify libvirt when the guest's PCI detach has actually completed, I have to stick in an arbitrary call to sleep() which is generally *way* too long, but may be too short in some cases of extremely high load. The only comment I got from IRC on Friday afternoon (I know - not a good time to be looking for people) was that they would be "surprised if it did work". So, I have the following questions: 1) Should this work? If it's supposed to work now: 2) can you give hints (aside from watching the qemu monitor commands and responses with stap) on what I might need to change, or how to further debug my problem within qemu? (I'm pretty well convinced that the libvirt code is doing the tap device creation/etc correctly). 3) alternately can you verify that this is a known bug? Is fixing it on anyone's todo list? If it's not supposed to work now: 4) Does it sound like a reasonable thing for qemu to support? 5) Is there some other formal way to request addition of this functionality (aside from figuring it out myself and posting a patch)? ******************************************** For reference, here is the sequence of qemu monitor commands sent by libvirt to fully detach, then fully reattach a network device. Note that fd is a newly opened TAP device. Also note the 3 second interval between the netdev_del and the next command: 96.671 > 0x7f8e20000c90 {"execute":"device_del","arguments":{"id":"net0"},"id":"libvirt-25"} 96.673 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-25"} 96.674 > 0x7f8e20000c90 {"execute":"netdev_del","arguments":{"id":"hostnet0"},"id":"libvirt-26"} 96.695 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-26"} 99.777 > 0x7f8e20000c90 {"execute":"getfd","arguments":{"fdname":"fd-net0"},"id":"libvirt-27"} (fd=27) 99.777 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-27"} 99.778 > 0x7f8e20000c90 {"execute":"netdev_add","arguments":{"type":"tap","fd":"fd-net0","id":"hostnet0"},"id":"libvirt-28"} 99.778 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-28"} 99.779 > 0x7f8e20000c90 {"execute":"device_add","arguments":{"driver":"virtio-net-pci","netdev":"hostnet0","id":"net0","mac":"52:54:00:d8:bd:b9","bus":"pci.0","addr":"0x4"},"id":"libvirt-29"} 99.780 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-29"} After this sequence is done, the guest network device is fully functioning. Here is the sequence sent to disconnect only the host side, then reconnect it with a new tap device. (although the fd is the same, this is because the old tap device had already been closed, so the number is just being used - the same thing happens when doing sequential full detach/attach cycles, and they all work with no problems): 168.750 > 0x7f8e20000c90 {"execute":"netdev_del","arguments":{"id":"hostnet0"},"id":"libvirt-30"} 168.762 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-30"} 168.800 > 0x7f8e20000c90 {"execute":"getfd","arguments":{"fdname":"fd-net0"},"id":"libvirt-31"} (fd=27) 168.801 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-31"} 168.801 > 0x7f8e20000c90 {"execute":"netdev_add","arguments":{"type":"tap","fd":"fd-net0","id":"hostnet0"},"id":"libvirt-32"} 168.802 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-32"} 168.802 > 0x7f8e20000c90 {"execute":"set_link","arguments":{"name":"net0","up":true},"id":"libvirt-33"} 168.803 < 0x7f8e20000c90 {"return": {}, "id": "libvirt-33"} After this sequence is done, everything about the network device *appears* normal on both the guest and host (at least the things I know to look at), but no traffic from the host shows up in a tcpdump of the interface on the guest, and no traffic from the guest shows up in a tcpdump of the tap device on the host. Oh - the extra "set_link" command at the end is because I noticed that the flags shown in ifconfig in the guest switched from: UP BROADCAST RUNNING MULTICAST to UP BROADCAST MULTICAST when reconnecting in this way, so I was hoping that forcing the interface up would solve my problems. It didn't :-/ (Another note: I also tried adding a delay after the netdev_del, and that also did nothing.)

[libvirt] CPU utilization between physical CPU and virtual CPU in KVM
by Dennis Chen 16 Oct '12

16 Oct '12

Hi All, I am confused by the following observed scenario: In my 4-CPU (KVM supported, 2 core with 2 thread for each) host machine box, I create only one VM with 3-vCPU through virsh/libvirt tools and also I pin this VM process to the physical processor 3. I guess the CPU utilization for the processor 3 will not exceed 100%, then I create 3 process (dead loop-- while(1);) and bind each of them to vCPU[0-2] respectively, through the "top -c" command in VM environment, I can see the CPU utilization for each of the vCPU is about 100%, but interesting, I found that the CPU utilization of processor 3 in the host machine is about 300% with "toc -c" command. why does a single process bound to a CPU can get ~300% cpu bandwidth in this case, does the kernel scheduler dispatch the idle cycle capacity of the CPUs to the virtual CPU of the VM, other word, the scheduler knows the vCPU info in the VM process? For the same case, if I create another 4 new dead-loop processes and bind them to the physical CPU[0-3] equally, then I find the vCPU0/1 in VM will not be 100%, eg. 32%, (I think the scheduler in the guest OS doesn't know it's running in a virtual environment, so the utilization of the vCPU will not change to adapt to the physical processor utilization, but it did, why? -org-gnu

[libvirt] necessary to limit container's network bandwidth when use physical nic in container?
by Gao feng 16 Oct '12

16 Oct '12

we can use tc to limit container's network bandwidth when the container uses veth device. because one of the veth devices will be seen in the host.so we can set tc rules on this device on the host. I want to know if it's necessary to limit container's network bandwidth when the container uses a physical nic device. because this nic device is only used by this container. And if this is necessary,Be there any good idea? Thanks!

[libvirt] [PATCH 0/8] RFC New API to retrieve host node CPU map
by Viktor Mihajlovski 15 Oct '12

15 Oct '12

Rationale: In order to use the APIs listed below it is necessary for a client to know the maximum number of node CPUs which is passed via the maplen argument. virDomainGetEmulatorPinInfo virDomainGetVcpuPinInfo virDomainGetVcpus virDomainPinEmulator virDomainPinVcpu virDomainPinVcpuFlags The current approach uses virNodeGetInfo to determine the maximum CPU number. This can lead to incorrect results if not all node CPUs are online. The maximum CPU number should always be the number of CPUs present on the host, regardless of their online/offline state. The following example illustrates the issue: Host has 3 logical CPUs, 1 socket, 3 cores, 1 thread. Guest has 1 virtual CPU and is started while all 3 host CPUs are online. $ virsh vcpuinfo guest VCPU: 0 CPU: 0 State: running CPU time: 35.4s CPU Affinity: yyy $ echo 0 > /sys/devices/system/cpu/cpu1/online $ virsh vcpuinfo guest VCPU: 0 CPU: 0 State: running CPU time: 35.5s CPU Affinity: y- The correct display for CPU affinity would have been y-y, as the guest continues to use CPUs 0 and 2. This is not a display problem only, because it is also not possible to explicitly pin the virtual CPU to host CPUs 0 and 2, due to the truncated CPU mask. PROPOSAL: To help solve the issue above I suggest a new public API: int virNodeGetCPUMapFlags(virConnectPtr conn, unsigned char **cpumap, unsigned int *online, unsigned int flags); The function will return the number of CPUs present on the host or -1 on failure; If cpumap is non-NULL virNodeGetCPUMapFlags will allocate an array containing a bit map representation of the online CPUs. It's the callers responsibility to deallocate cpumap using free(). If online is non-NULL, the variable pointed to will contain the number of online host node CPUs. The variable flags has been added to support future extensions and must be set to 0. Clients can use virNodeGetCPUMapFlags to properly determine the maximum number of node CPUs and their online/offline state. Remarks: This series implements the QEMU and test drivers. This series doesn't introduce changes to the existing vcpu pinning, which I would submit as a succeeding patch set. No python binding yet.

[libvirt] [PATCH] RFC: Clarify the relationship between <vcpu>, <vcpupin>, and <emulatorpin>
by Osier Yang 15 Oct '12

15 Oct '12

These 3 elements conflicts with each other in either the doc or the underlying codes are. This is to propse a solution. Before writing any codes, I want to see if the principle is correct, any advise is welcomed. Current problems: Problem 1: The doc shouldn't simply say "These settings are superseded by CPU tuning. " for element <vcpu>. As except the tuning, <vcpu> allows to specify the current, maxmum vcpu number. Apart from that, <vcpu> also allows to specify the placement as "auto", which binds the domain process to the advisory nodeset from numad. Problem 2: Doc for <vcpu> says its "cpuset" specify the physical CPUs that the vcpus can be pinned. But it's not the truth, as actually it only pin domain process to the specified physical CPUs. So either it's a document bug, or code bug. Problem 3: Doc for <vcpupin> says it supersed "cpuset" of <vcpu>, it's not quite correct, as each <vcpupin> specify the pinning policy only for one vcpu. How about the ones which doesn't have <vcpupin> specified? it says the vcpu will be pinned to all available physical CPUs, but what's the meaning of attribute "cpuset" of <vcpu> then? Problem 4: Doc for <emulatorpin> says it pin the emulator threads (domain process in other context, perhaps another follow up patch to cleanup the inconsistency is needed) to the physical CPUs specified its attribute "cpuset". Which conflicts with <vcpu>'s "cpuset". And actually in the underlying codes, it set the affinity for domain process twice if both "cpuset" for <vcpu> and <emulatorpin> are specified, and <emulatorpin>'s pinning will override <vcpu>'s. Problem 5: When "placement" of <vcpu> is "auto" (I.e. uses numad to get the advisory nodeset to which the domain process is pinned to), it will also be overridden by <emulatorpin>, This patch is trying to sort out the conflicts or bugs by: 1) Don't say <vcpu> is superseded by <cputune> 2) Keep the semanteme for "cpuset" of <vcpu> (I.e. Still says it specify the physical CPUs the virtual CPUs). But modifying it to mention it also set the pinning policy for domain process, and the CPU placement of domain process specified by "cpuset" of <vcpu> will be ingored if <emulatorpin> specified, and similary, the CPU placement of vcpu thread will be ignored if it has <vcpupin> specified, for vcpu which doesn't have <vcpupin> specified, it inherits "cpuset" of <vcpu>. 3) Don't say <vcpu> is supersed by <vcpupin>. If neither <vcpupin> nor "cpuset" of <vcpu> is specified, the vcpu will be pinned to all available pCPUs. 4) If neither <emulatorpin> nor "cpuset" of <vcpu> is specified, the domain process (emulator threads in the context) will be pinned to all available pCPUs. 5) If "placement" of <vcpu> is "auto", <emulatorpin> is not allowed. 6) hotplugged vcpus will also inherit "cpuset" of <vcpu> Codes changes above document changes will cause: 1) Inherit def->cpumask for each vcpu which doesn't have <vcpupin> specified, during parsing. 2) ping the vcpu which doesn't have <vcpupin> specified to def->cpumask either by cgroup for sched_setaffinity(2), which is actually done by 1). 3) Error out if "placement" == "auto", and <emulatorpin> is specified. Otherwise, <emulatorpin> is honored, and "cpuset" of <cpuset> is ignored. 4) Setup cgroup for each hotplugged vcpu, and setup the pinning policy by either cgroup or sched_setaffinity(2). 5) Remove cgroup and <vcpupin> for each hot unplugged vcpu. --- docs/formatdomain.html.in | 42 +++++++++++++++++++++++++++--------------- 1 files changed, 27 insertions(+), 15 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index d664e7e..1ae8cf4 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -357,8 +357,18 @@ the maximum supported by the hypervisor.

[libvirt] Some questions about virConnectAuthCallbackPtr
by Richard W.M. Jones 15 Oct '12

15 Oct '12

Some questions which seem to be left ambigious by the documentation for virConnectAuthCallbackPtr: http://libvirt.org/html/libvirt-libvirt.html#virConnectAuthCallbackPtr (1) For a single open, can this be called multiple times? I'm thinking, some authentication methods might give the user N attempts at typing the password, which might result in N callbacks here. (2) The documentation says: "Returns: 0 if all interactions were filled, or -1 upon error". However it also says "If an interaction cannot be filled, fill in NULL and 0". Does that mean it's OK (not an error, return 0) if a result field is set to NULL?

[libvirt] [PATCH 0/3] Add option to selectively enable IPv4/v6 forwarding
by Benjamin Cama 15 Oct '12

15 Oct '12

Hi, Currently, when IP forwarding is enabled in a network element, libvirt enables forwarding for IPv4/v6 on the OS if the bridge has some IP address of that family. In some circumstances, one could only want forwarding for one family and not the other, even if both address families are present; for example, forwarding only IPv6 but still have some RFC1918 addresses on the “local” network as a backup stack, or playing with IPv6 using (not forwarded) ULA addresses, having some IPv4 NATed forwarding, without loosing IPv6 connectivity because enabling it will disable auto-configuration (my case). This patch adds a new optional "family" attribute to the "forward" element, allowing selective forwarding: it can be set to "ipv4" or "ipv6". If not present, the usual behavior of libvirt is kept, forwarding trafic for whichever family there is an address on the bridge. The first patch also remove libvirt's ability to set forwarding; I think it should only check for it, letting the administrator enable it the usual way (/etc/sysctl.conf or wathever) if he really wants it. In my case, this behavior caused me to loose IPv6 connectivity when adding some ULA addresse to my VMs bridge, because IPv6 forwarding was enabled in my back. Regards, Benjamin Cama (3): Only check for IP forwarding, do not enable it Add a "forward family" option Take the forwarding family into account src/conf/network_conf.c | 58 ++++++++++++++++++++++++++++++- src/conf/network_conf.h | 1 + src/network/bridge_driver.c | 81 +++++++++++++++++++++++++++++++++--------- 3 files changed, 121 insertions(+), 19 deletions(-) -- 1.7.2.5

[libvirt] [PATCHv3] Add support for SUSPEND_DISK event
by Martin Kletzander 15 Oct '12

15 Oct '12

This patch adds support for SUSPEND_DISK event; both lifecycle and separated. The support is added for QEMU, machines are changed to PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes to shut-off. This and much more needs to be done in order for libvirt to work with transient devices, wake-ups etc. This patch is not aiming for that functionality. --- daemon/remote.c | 25 +++++++++++ examples/domain-events/events-c/event-test.c | 22 +++++++++- examples/domain-events/events-python/event-test.py | 3 +- include/libvirt/libvirt.h.in | 29 +++++++++++++ python/libvirt-override-virConnect.py | 9 ++++ python/libvirt-override.c | 50 ++++++++++++++++++++++ src/conf/domain_event.c | 30 ++++++++++++- src/conf/domain_event.h | 4 ++ src/libvirt_private.syms | 2 + src/qemu/qemu_monitor.c | 10 +++++ src/qemu/qemu_monitor.h | 3 ++ src/qemu/qemu_monitor_json.c | 9 ++++ src/qemu/qemu_process.c | 47 ++++++++++++++++++++ src/remote/remote_driver.c | 31 ++++++++++++++ src/remote/remote_protocol.x | 7 ++- src/remote_protocol-structs | 4 ++ 16 files changed, 281 insertions(+), 4 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index e7fe128..2d3f401 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -608,6 +608,30 @@ remoteRelayDomainEventBalloonChange(virConnectPtr conn ATTRIBUTE_UNUSED, } +static int remoteRelayDomainEventPMSuspendDisk(virConnectPtr conn ATTRIBUTE_UNUSED, + virDomainPtr dom, + int reason ATTRIBUTE_UNUSED, + void *opaque) { + virNetServerClientPtr client = opaque;

[libvirt] [PATCH] node_memory: Add new parameter field to tune the new sysfs knob
by Osier Yang 15 Oct '12

15 Oct '12

Upstream kernel introduced new sysfs knob "merge_across_nodes" to specify if pages from different numa nodes can be merged. When set to 0, only pages which physically reside in the memory area of same NUMA node can be merged. When set to 1, pages from all nodes can be merged. This patch supports the tuning by adding new param field "shm-merge-across-nodes". --- Perhaps two bool options like "--disable-shm-merge-across-nodes", and "--enable-shm-merge-across-nodes" are good, but could the kernel sysfs knob have other values beyond 0 and 1 in future? --- include/libvirt/libvirt.h.in | 10 ++++++++++ src/nodeinfo.c | 26 +++++++++++++++++++++++--- tools/virsh-host.c | 20 ++++++++++++++++++++ tools/virsh.pod | 5 ++++- 4 files changed, 57 insertions(+), 4 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 81f12a4..56ee2f5 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -4489,6 +4489,16 @@ typedef virMemoryParameter *virMemoryParameterPtr; */ # define VIR_NODE_MEMORY_SHARED_FULL_SCANS "shm_full_scans" +/* VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES: + * + * Macro for typed parameter that represents whether pages from + * different NUMA nodes can be merged, when its value is 0, only + * pages which physically reside in the memory area of same NUMA + * node are merged, otherwise pages from all nodes can be merged. + */ +# define VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES "shm_merge_across_nodes" + + int virNodeGetMemoryParameters(virConnectPtr conn, virTypedParameterPtr params, int *nparams, diff --git a/src/nodeinfo.c b/src/nodeinfo.c index 021eb05..6002789 100644 --- a/src/nodeinfo.c +++ b/src/nodeinfo.c @@ -1004,6 +1004,13 @@ nodeSetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, /* Out of memory */ if (ret == -2) return -1; + } else if (STREQ(param->field, + VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES)) { + ret = nodeSetMemoryParameterValue("merge_across_nodes", param); + + /* Out of memory */ + if (ret == -2) + return -1; } } @@ -1039,8 +1046,9 @@ nodeGetMemoryParameterValue(const char *field, if ((tmp = strchr(buf, '\n'))) *tmp = '\0'; - if (STREQ(field, "pages_to_scan") || - STREQ(field, "sleep_millisecs")) + if (STREQ(field, "pages_to_scan") || + STREQ(field, "sleep_millisecs") || + STREQ(field, "merge_across_nodes")) rc = virStrToLong_ui(buf, NULL, 10, (unsigned int *)value); else if (STREQ(field, "pages_shared") || STREQ(field, "pages_sharing") || @@ -1063,7 +1071,7 @@ cleanup: } #endif -#define NODE_MEMORY_PARAMETERS_NUM 7 +#define NODE_MEMORY_PARAMETERS_NUM 8 int nodeGetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, virTypedParameterPtr params ATTRIBUTE_UNUSED, @@ -1075,6 +1083,7 @@ nodeGetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, #ifdef __linux__ unsigned int pages_to_scan; unsigned int sleep_millisecs; + unsigned int merge_across_nodes; unsigned long long pages_shared; unsigned long long pages_sharing; unsigned long long pages_unshared; @@ -1168,6 +1177,17 @@ nodeGetMemoryParameters(virConnectPtr conn ATTRIBUTE_UNUSED, break; + case 7: + if (nodeGetMemoryParameterValue("merge_across_nodes", + &merge_across_nodes) < 0) + return -1; + + if (virTypedParameterAssign(param, VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES, + VIR_TYPED_PARAM_UINT, merge_across_nodes) < 0) + return -1; + + break; + default: break; } diff --git a/tools/virsh-host.c b/tools/virsh-host.c index 2c46336..62ecafc 100644 --- a/tools/virsh-host.c +++ b/tools/virsh-host.c @@ -900,6 +900,8 @@ static const vshCmdOptDef opts_node_memory_tune[] = { {"shm-sleep-millisecs", VSH_OT_INT, VSH_OFLAG_NONE, N_("number of millisecs the shared memory service should " "sleep before next scan")}, + {"shm-merge-across-nodes", VSH_OT_INT, VSH_OFLAG_NONE, + N_("Specifies if pages from different numa nodes can be merged")}, {NULL, 0, 0, NULL} }; @@ -911,6 +913,7 @@ cmdNodeMemoryTune(vshControl *ctl, const vshCmd *cmd) unsigned int flags = 0; unsigned int shm_pages_to_scan = 0; unsigned int shm_sleep_millisecs = 0; + unsigned int shm_merge_across_nodes = 0; bool ret = false; int i = 0; @@ -926,12 +929,21 @@ cmdNodeMemoryTune(vshControl *ctl, const vshCmd *cmd) return false; } + if (vshCommandOptUInt(cmd, "shm-merge-across-nodes", + &shm_merge_across_nodes) < 0) { + vshError(ctl, "%s", _("invalid shm-merge-across-nodes number")); + return false; + } + if (shm_pages_to_scan) nparams++; if (shm_sleep_millisecs) nparams++; + if (shm_merge_across_nodes) + nparams++; + if (nparams == 0) { /* Get the number of memory parameters */ if (virNodeGetMemoryParameters(ctl->conn, NULL, &nparams, flags) != 0) { @@ -983,6 +995,14 @@ cmdNodeMemoryTune(vshControl *ctl, const vshCmd *cmd) goto error; } + if (i < nparams && shm_merge_across_nodes) { + if (virTypedParameterAssign(&params[i++], + VIR_NODE_MEMORY_SHARED_MERGE_ACROSS_NODES, + VIR_TYPED_PARAM_UINT, + shm_merge_across_nodes) < 0) + goto error; + } + if (virNodeSetMemoryParameters(ctl->conn, params, nparams, flags) != 0) goto error; else diff --git a/tools/virsh.pod b/tools/virsh.pod index 2120429..d975f06 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -299,7 +299,10 @@ Allows you to display or set the node memory parameters.

[libvirt] [PATCHv2 3/4] qemu: reorganize qemuDomainChangeNet
by Laine Stump 15 Oct '12

15 Oct '12

(V1 of this patch is in the following thread: https://www.redhat.com/archives/libvir-list/2012-October/msg00542.html I'm posting it because PATCH 4/4 of that series attempts to use apparently non-existent/non-working functionality in qemu; modifying PATCH 3/4 slightly gives back some of the functionality lost by not having 4/4. Once this is ACKed, I will push 1-3 only, and leave 4/4 untilits problem is discovered/resolved) **** This patch resolves: https://bugzilla.redhat.com/show_bug.cgi?id=805071 to the extent that it can be resolved with current qemu functionality. It attempts to detect as many situations as possible when the simple operation of disconnecting an existing tap device from one bridge and attaching it to another will satisfy the change requested in virDomainUpdateDeviceFlags() for a network device. Before this patch, that situation could only be detected if the pre-change interface *and* the post-change interface definition were both "type='bridge'". After this patch, it can also be detected if the before or after interfaces are any combination of type='bridge' and type='network' (the networks can be <forward mode='nat|route|bridge'>, as long as they use a Linux host bridge and not macvtap connections). This extra effort is especially useful since the recent discovery that a netdev_del+netdev_add combo (to reconnect the network device with completely different hostside configuration) doesn't work properly with current qemu (1.2) unless it is accompanied by the matching device_del+device_add - see this mailing list message for details: http://lists.nongnu.org/archive/html/qemu-devel/2012-10/msg02355.html (A slight modification of the patch referenced there has been prepared to apply on top of this patch, but won't be pushed until qemu can be made to work with it.) * qemuDomainChangeNet needs access to the virDomainDeviceDef that holds the new netdef (so that it can clear out the virDomainDeviceDef if it ends up using the NetDef to replace the original), so the virDomainNetDefPtr arg is replaced with a virDomainDeviceDefPtr. * qemuDomainChangeNet previously checked for *some* changes to the interface config, but this check was by no means complete. It was also a bit disorganized. This refactoring of the code is (I believe) complete in its check of all NetDef attributes that might be changed, and either returns a failure (for changes that are simply impossible), or sets one of three flags: needLinkStateChange - if the device link state needs to go up/down needBridgeChange - if everything else is the same, but it needs to be connected to a difference linux host bridge needReconnect - if the entire host side of the device needs to be torn down and reconstructed (currently non-working, as mentioned above) Note that this function will refuse to make any change that requires the *guest* side of the device to be detached (e.g. changing the PCI address or mac address). Those would be disruptive enough to the guest that it's reasonable to require an explicit detach/attach sequence from the management application. * As mentioned above, qemuDomainChangeNet also does its best to understand when a simple change in attached bridge for the existing tap device will work vs. the need to completely tear down/reconstruct the host side of the device (including tap device). This patch *does not* implement the "reconnect" code anyway - there is a placeholder that turns that into an error. Rather, the purpose of this patch is to replicate existing behavior with code that is ready to have that functionality plugged in in a later patch. * The expanded uses for qemuDomainChangeNetBridge meant that it needed to be enhanced as well - it no longer replaces the original brname string in olddev with the new brname; instead, it relies on the caller to replace the *entire* olddev with newdev (since we've gone to great lengths to assure they are functionally identical other than the name of the bridge, this is now not only safe, but more correct). Additionally, qemuDomainNetChangeBridge can now set the bridge for type='network' interfaces as well as plain type='bridge' interfaces. (Note that I had to make this change simultaneous to the reorganization of qemuDomainChangeNet because the two are too closely intertwined to separate). --- src/qemu/qemu_driver.c | 2 +- src/qemu/qemu_hotplug.c | 502 ++++++++++++++++++++++++++++++++++++++---------- src/qemu/qemu_hotplug.h | 4 +- 3 files changed, 401 insertions(+), 107 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 0787039..3a78465 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -5987,7 +5987,7 @@ qemuDomainUpdateDeviceLive(virDomainObjPtr vm, ret = qemuDomainChangeGraphics(driver, vm, dev->data.graphics);

[libvirt] Potential race condition problem
by Benjamin Wang (gendwang) 15 Oct '12

15 Oct '12

Hi, Currently virInitialize() method defined in libvirt.c has the following code: int virInitialize(void) { if (initialized) return 0; initialized = 1; if (virThreadInitialize() < 0 || virErrorInitialize() < 0 || virRandomInitialize(time(NULL) ^ getpid()) || virNodeSuspendInit() < 0) return -1; ...... } When two threads access virInitialize method, there is no lock for the "initialized" parameter. If the first thread enters this method and set "initialized" to 1, the second thread could see that "initialized" is 1(Because initialized is not volatiled, I say could). In some situation, before the first thread finishes all the initialization, the second thread could use some resources which should be initialized in Initialize method. If you have any comments, please let me know. Thanks! B.R. Benjamin Wang
