[libvirt] [PATCH 1/2] conf: make disk source pool translation generic
by Roman Bogorodskiy 15 Aug '14

15 Aug '14

Currently, qemu driver uses qemuTranslateDiskSourcePool() to translate disk volume information. This function is general enough and could be used for other drivers as well, so move it to conf/domain_conf.c along with its helpers. - qemuTranslateDiskSourcePool: move to conf/domain_conf.c and rename to virDomainTranslateDiskSourcePool, - qemuAddISCSIPoolSourceHost: move to conf/domain_conf.c and rename to virDomainAddISCSIPoolSourceHost, - qemuTranslateDiskSourcePoolAuth: move to conf/domain_conf.c and rename to virDomainTranslateDiskSourcePoolAuth, - Expose virDomainTranslateDiskSourcePool through libvirt_private.syms, - Update users of virDomainTranslateDiskSourcePool to use a new name. --- src/conf/domain_conf.c | 245 +++++++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 3 + src/libvirt_private.syms | 1 + src/qemu/qemu_conf.c | 243 ---------------------------------------------- src/qemu/qemu_conf.h | 3 - src/qemu/qemu_driver.c | 6 +- src/qemu/qemu_hotplug.c | 2 +- src/qemu/qemu_process.c | 4 +- tests/qemuxml2argvtest.c | 2 +- 9 files changed, 256 insertions(+), 253 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 5c762fa..d5f80e0 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -20045,6 +20045,251 @@ virDomainDiskSourceIsBlockType(virDomainDiskDefPtr def) } +static int +virDomainAddISCSIPoolSourceHost(virDomainDiskDefPtr def, + virStoragePoolDefPtr pooldef) +{ + int ret = -1;

[libvirt] [PATCH] daemon: Fix driver registration ordering
by Michal Privoznik 15 Aug '14

15 Aug '14

There are some stateless drivers which implement subdrivers (typically vbox and its own network and storage subdrivers). However, as of ba5f3c7c8ecc10 the vbox driver lives in the daemon, not the client library. This means, in order for vbox (or any stateless domain driver) to use its subdrivers, it must register before the general drivers. Later, when the virConnectOpen function goes through the subdrivers, stateless drivers are searched first. If the connection request is aiming at stateless driver, it will be opened. Otherwise the generic subdriver is opened. The other change done in this commit is moving interface module load a bit earlier to match the ordering in case libvirt is built without driver modules.

He also supplied a patch. http://www.redhat.com/archives/libvir-list/2014-August/msg00655.html I expanded on that patch by cleaning uyp now-extraneous checks in the callers of networkCreateInterfacePool(). Fortunately the offending patch hasn't been in any release, and hasn't been (to my knowledge) backported to any other branch. --- src/network/bridge_driver.c | 17 +++++++---------- 1 file changed, 7 insertions(+), 10 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 1ba4c3d..fc4c73d 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -2196,6 +2196,9 @@ networkCreateInterfacePool(virNetworkDefPtr netdef) int ret = -1; size_t i; + if (!netdef->forward.npfs || netdef->forward.nifs > 0) + return 0; + if ((virNetDevGetVirtualFunctions(netdef->forward.pfs->dev, &vfNames, &virtFns, &numVirtFns)) < 0) { virReportError(VIR_ERR_INTERNAL_ERROR, @@ -2204,7 +2207,6 @@ networkCreateInterfacePool(virNetworkDefPtr netdef) goto cleanup; } - netdef->forward.nifs = 0; if (VIR_ALLOC_N(netdef->forward.ifs, numVirtFns) < 0) goto cleanup; @@ -3843,10 +3845,8 @@ networkAllocateActualDevice(virDomainDefPtr dom, virDomainHostdevSubsysPCIBackendType backend; iface->data.network.actual->type = actualType = VIR_DOMAIN_NET_TYPE_HOSTDEV; - if (netdef->forward.npfs > 0 && netdef->forward.nifs <= 0 && - networkCreateInterfacePool(netdef) < 0) { + if (networkCreateInterfacePool(netdef) < 0) goto error; - } /* pick first dev with 0 connections */ for (i = 0; i < netdef->forward.nifs; i++) { @@ -3978,10 +3978,8 @@ networkAllocateActualDevice(virDomainDefPtr dom, } else { /* pick an interface from the pool */ - if (netdef->forward.npfs > 0 && netdef->forward.nifs == 0 && - networkCreateInterfacePool(netdef) < 0) { + if (networkCreateInterfacePool(netdef) < 0) goto error; - } /* PASSTHROUGH mode, and PRIVATE Mode + 802.1Qbh both * require exclusive access to a device, so current @@ -4149,10 +4147,9 @@ networkNotifyActualDevice(virDomainDefPtr dom, goto success; } - if (netdef->forward.npfs > 0 && netdef->forward.nifs == 0 && - networkCreateInterfacePool(netdef) < 0) { + if (networkCreateInterfacePool(netdef) < 0) goto error; - } + if (netdef->forward.nifs == 0) { virReportError(VIR_ERR_INTERNAL_ERROR, _("network '%s' uses a direct or hostdev mode, " -- 1.9.3

[libvirt] [PATCH v2 1/1] qemu: Tidy up job handling during live migration
by Sam Bobroff 15 Aug '14

15 Aug '14

During a QEMU live migration several warning messages about job handling could be written to syslog on the destination host: "entering monitor without asking for a nested job is dangerous" The messages are written because the job handling during migration uses hard coded asyncJob values in several places that are incorrect. This patch passes the required asyncJob value around and prevents the warnings as well as any issues that the warnings may be referring to.

[libvirt] [PATCH 00/66] vbox: Rewrite vbox domain driver
by Taowei 15 Aug '14

15 Aug '14

This series of patches rewrite the vbox's domain driver. The driver is separated into two parts: the version specified and the common part. The common driver use vboxUniformedAPI to build a general driver for all vbox versions. The vboxUniformedAPI take the responsiblity to communicate with virtualbox. Since there are some incompatible changes in virtualbox, vboxUniformedAPI should be aware of these changes and provide a uniformed api for the upper layer. The significant result of this patch is that we replace all vir${vbox_version}Driver into one virCommonDriver. So, we will have only one vbox driver implementation for all vbox versions in libvirt. PS: I have send part of my patches before: https://www.redhat.com/archives/libvir-list/2014-July/msg00937.html But I have to resend it beacuse I did some improvement on previous patches: *Remove the test case for vboxUniformedAPI, because it would raise "break strict-aliasing rules" warning in some distibutions *Merged the flag fdWatchNeedInitialize into domainEventCallbacks, So, we use one flag to indicate whether vbox support callbacks as well as we need to initialize variables for it.

[libvirt] [PATCH] build: force configure failed when perl is missing
by Jincheng Miao 15 Aug '14

15 Aug '14

Perl is necessary to our build processing, it will invoke a lot of generating script, like: gendispatch.pl. If perl is missing, it's ok for build from git checkout, because autogen.sh will tell you. But for compiling from a release tarball, configure will just record a missing message, and continue, then build failed, like: https://www.redhat.com/archives/libvirt-users/2014-August/msg00050.html So need to enhance configure script to handle this negative case.

[libvirt] questions on backing chain file, block lun, active commit
by Eric Blake 14 Aug '14

14 Aug '14

While investigating active commit, I noticed that our code for probing backing chains currently guesses at type="file" vs. type="block" solely based on stat results (regular file vs. block device). Is a block device allowed to be used as <disk type='block' device='lun'> at the same time it has qcow2 format, or does use of device='lun' enforce that the block device is used with raw format? My worry is that if a lun device can be used with qcow2 format, then it can have a non-block backing file, and an active commit would convert <disk type='block' device='lun'> into <disk type='file' device='lun'> which is not valid. On a related vein, that means that an active commit currently auto-picks whether the <disk> will be listed as type='file' or type='block' solely on the stat results. Elsewhere, we allow type='file' even for block devices, where a noticeable difference is how virDomainGetBlockInfo() reports allocation (for type='file', allocation is based on how sparse the file is, but a block device is not sparse; for type='block', allocation is based on asking qemu the maximum used cluster). Should we be auto-converting to type='block' in other cases where we have stat results? For example, I posted a patch today to let the user explicitly request that virsh blockcopy to a block device will use type='block' because the existing code has always used type='file', but if we were doing things automatically, then the user would automatically get type='block' for block device destinations instead of having to request it; but has no way to forcefully list a file even when the destination is a block (at least, not until I implement virDomainBlockCopy() that takes an XML <disk> description). One drawback of autoconversion is the XML changes - with type='file', the host resource is located at xpath disk/source/@file, but with type='block', it is at xpath disk/source/@dev. If we ever convert a user's type='file' into a block device, but the user isn't expecting the conversion, then they won't be able to find the source file name in the output XML. So on that ground, autoprobing type='block' for active commit is fishy; we really should be honoring the user's input for <backingStore> rather than probing it ourselves every time. Until that point, and given that I just proposed a patch to turn on type='block' for blockcopy, where type='file' is used in all other cases, should we have the same sort of flag for active commit? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH] [RFC] net: don't segfault on Martin's setup
by Martin Kletzander 14 Aug '14

14 Aug '14

No, don't worry, this is not a real commit message, this is more like an RFC about how to fix it. I'm not sure about this part of libvirt codebase, so I'm rather asking for help. Apparently, I have a network with netdef->forward.pfs == NULL, I suspect this is a network I have, that doesn't have any <forward/> element. With the following fix, everything works as expected, but I'm almost certain this is not enough.

[libvirt] [PATCH] LXC: Fix virLXCControllerSetupDevPTS() wrt user namespaces
by Richard Weinberger 14 Aug '14

14 Aug '14

The gid value passed to devpts has to be translated by hand as virLXCControllerSetupDevPTS() is called before setting up the user and group mappings. Otherwise devpts will use an unmapped gid and openpty() will fail within containers. Linux commit commit 23adbe12 ("fs,userns: Change inode_capable to capable_wrt_inode_uidgid") uncovered that issue.

[libvirt] [PATCH] qemu: Issue rtc_reset_reinjection command after guest-set-time
by Michal Privoznik 14 Aug '14

14 Aug '14

An advice appeared there on the qemu-devel list [1]. When a domain is suspended and then resumed guest kernel is not aware of this. So we've introduced virDomainSetTime API that resets the time within guest using qemu-ga. On the other hand, qemu itself is trying to make RTC beat faster to catch the difference. But if we don't tell qemu that guest's time was reset via the other method, both mechanisms are applied resulting in again wrong guest time. In order to avoid summing both corrections we need to tell qemu that it should not use the RTC injection if the guest time is set via guest agent. 1: http://www.mail-archive.com/qemu-devel@nongnu.org/msg236435.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/qemu/qemu_driver.c | 10 ++++++++++ src/qemu/qemu_monitor.c | 33 +++++++++++++++++++++++++++++++++ src/qemu/qemu_monitor.h | 2 ++ src/qemu/qemu_monitor_json.c | 21 +++++++++++++++++++++ src/qemu/qemu_monitor_json.h | 2 ++ 5 files changed, 68 insertions(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index b6219ba..bdfd155 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -16879,6 +16879,16 @@ qemuDomainSetTime(virDomainPtr dom, rv = qemuAgentSetTime(priv->agent, seconds, nseconds, rtcSync); qemuDomainObjExitAgent(vm); + if (!virDomainObjIsActive(vm)) { + virReportError(VIR_ERR_OPERATION_INVALID, + "%s", _("domain is not running")); + goto endjob; + } + + qemuDomainObjEnterMonitor(driver, vm); + rv = qemuMonitorRTCResetReinjection(priv->mon); + qemuDomainObjExitMonitor(driver, vm); + if (rv < 0) goto endjob; diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 3d9f87b..77627bc 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -4037,3 +4037,36 @@ qemuMonitorGetGuestCPU(qemuMonitorPtr mon, return qemuMonitorJSONGetGuestCPU(mon, arch, data); } + +/** + * qemuMonitorRTCResetReinjection: + * @mon: Pointer to the monitor + * + * Issue rtc-reset-reinjection command. + * This should be used in cases where guest time is restored via + * guest agent so RTC injection is not needed (in fact it will + * confuse guest's RTC). + * + * Returns 0 on success + * -1 on error. + */ +int +qemuMonitorRTCResetReinjection(qemuMonitorPtr mon) +{ + + VIR_DEBUG("mon=%p", mon); + + if (!mon) { + virReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + + if (!mon->json) { + virReportError(VIR_ERR_OPERATION_UNSUPPORTED, "%s", + _("JSON monitor is required")); + return -1; + } + + return qemuMonitorJSONRTCResetReinjection(mon); +} diff --git a/src/qemu/qemu_monitor.h b/src/qemu/qemu_monitor.h index c3695f2..4fd6f01 100644 --- a/src/qemu/qemu_monitor.h +++ b/src/qemu/qemu_monitor.h @@ -790,6 +790,8 @@ int qemuMonitorGetGuestCPU(qemuMonitorPtr mon, virArch arch, virCPUDataPtr *data); +int qemuMonitorRTCResetReinjection(qemuMonitorPtr mon); + /** * When running two dd process and using <> redirection, we need a * shell that will not truncate files.

[libvirt] [PATCH] Always add 'console' matching the 'serial' device
by Ján Tomko 13 Aug '14

13 Aug '14

We have been formatting the first serial device also as a console device, but only if there were no other consoles. If there is a <serial> device present in the XML, but no serial <console>, or if there isn't any <console> at all but the domain definition hasn't gone through a parse->format->parse round-trip, the <console> device would not be formatted. Change the code to always add the stub device for the first serial device.

[libvirt] Pass additional environmental variables

We're using sasl+gssapi+kerberos to do authentication for libvirt, including from hypervisor to hypervisor. However, the environmental variable filtering implemented in libvirt prevents this from working, so we're forced to run a locally patched version.

[libvirt] [PATCH v2] storage: ZFS support
by Roman Bogorodskiy 12 Aug '14

12 Aug '14

Changes from the initial version: - Update docs/schemas and docs/storage.html.in with ZFS backend information - Drop StartPool and StopPool that does nothing and therefore not needed - Fix memory leak in 'tokens' variable - Fill volume key before creating a volume - Use volume's target.path as a key - Allow not to specify 'target' for pool because in any case it should be /dev/zvol/$poolname Few notes on Linux support: I've been playing around with http://zfsonlinux.org/. I noticed it missed '-H' switch to provide a machine-friendly output and created a feature request: https://github.com/zfsonlinux/zfs/issues/2522 It was quickly fixed, so I've updated from the git version and moved on. >From that point it worked well and the only thing I had to modify is not to pass 'volmode' parameter during volume creation (it's freebsd specific and it could be e.g. just cdev or a FreeBSD geom provider). So, basically, for the current (limited) feature set the two things need to be checked on Linux: - zpool get support for -H switch - zfs volmode support for volume creation I'm open for suggestions what would be a good way to check it. For the '-H' thing, I was thinking about calling just 'zpool get -H' in StartPool. If the error says 'invalid option 'H'' (i.e. check if it just contains 'H'), then return an error that zfs version is too old. That's fragile, but probably less fragile than parsing usage that looks like that: usage: get [-pH] <"all" | property[,...]> <pool> ... As for the 'volmode', it's simple in terms of parsing, because e.g. 'zfs get' prints a nice set of parameters e.g.: volblocksize NO YES 512 to 128k, power of 2 volmode YES YES default | geom | dev | none volsize YES NO <size> So it should not be a problem to check it once and save in some sort of state struct inside of the ZFS backend.

[libvirt] [RFC][scale] new API for querying domains stats
by Francesco Romani 12 Aug '14

12 Aug '14

Hi everyone, I'd like to discuss possible APIs and plans for new query APIs in libvirt. I'm one of the oVirt (http://www.ovirt.org) developers, and I write code for VDSM; VDSM is the node management daemon, which is in charge, among many other things, to gather the host and statistics per Domain/VM. Right now we aim for a number of VM per node in the (few) hundreds, but we have big plans to scale much more, and to possibly reach thousands in a not so distant future. At the moment, we use one thread per VM to gather the VM stats (CPU, network, disk), and of course this obviously scales poorly. This is made only worse by the fact that VDSM is a python 2.7 application, and notoriously python 2.x behaves very badly with threads. We are already working to improve our code, but I'd like to bring the discussion here and see if and when the querying API can be improved. We currently use these APIs for our sempling: virDomainBlockInfo virDomainGetInfo virDomainGetCPUStats virDomainBlockStats virDomainBlockStatsFlags virDomainInterfaceStats virDomainGetVcpusFlags virDomainGetMetadata What we'd like to have is * asynchronous APIs for querying domain stats (https://bugzilla.redhat.com/show_bug.cgi?id=1113106) This would be just awesome. Either a single callback or a different one per call is fine (let's discuss this!). please note that we are much more concerned about thread reduction then about performance numbers. We had report of thread number becoming a real harm, while performance so far is not yet a concern (https://bugzilla.redhat.com/show_bug.cgi?id=1102147#c54) * bulk APIs for querying domain stats (https://bugzilla.redhat.com/show_bug.cgi?id=1113116) would be really welcome as well. It is quite independent from the previous bullet point and would help us greatly with scale. So, I'd like to discuss if these additions are (or can be) in the project roadmap, and, if so, how the API could look like and what the possible timeframe could be. Of course I'd be happy to provide any further information about VDSM and its workings. Thoughts very welcome! Thanks and best regards, -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

[libvirt] Verifying libvirt release tarballs
by Richard Weinberger 12 Aug '14

12 Aug '14

Hi! How can I cryptographically verify libvirt releases? There are no signature/hash files in http://libvirt.org/sources/. All I see is that your git release tags are PGP signed. So, anyone who cares has to ignore everything in http://libvirt.org/sources/ and needs to regenerate the tarball from git. Or do I miss something? -- Thanks, //richard

[libvirt] [PATCH 1/1] qemu: Tidy up job handling during live migration
by Sam Bobroff 12 Aug '14

12 Aug '14

During a QEMU live migration several warning messages about job handling could be written to syslog on the destination host: "entering monitor without asking for a nested job is dangerous" The messages are written because the job handling during migration uses hard coded asyncJob values in several places that are incorrect. This patch passes the required asyncJob value around and prevents the warnings as well as any issues that the warnings may be referring to.

[libvirt] [PATCH] qemu: use guest-fsfreeze-freeze-list command if mountpoints to freeze specified
by Tomoki Sekiyama 12 Aug '14

12 Aug '14

A command to freeze a part of mounted file systems is implemented in upstream QEMU-guest-agent with a name of 'guest-fsfreeze-freeze-list'. This fixes the name of the command used to partial fsfreeze in qemu driver when 'mountpoints' option is specified to virDomainFSFreeze API.

[libvirt] [python-PATCH] Fix libvirt_longlongWrap returning a very large value
by Wang Rui 11 Aug '14

11 Aug '14

From: Zhou Yimin <zhouyimin(a)huawei.com> If hypervisor is not Xen, the errs in struct _virDomainBlockStats will be -1. But in KVM when we call domain.blockStats(), errs is 18446744073709551615. To fix that, this patch has two changes: 1. Replace use of the PyLong_FromUnsignedLongLong with PyLong_FromLongLong in function libvirt_longlongWrap 2. If the paramemter of libvirt_longlongWrap is unsigned long long, use libvirt_ulonglongWrap instead because of above change. After this patch, errs is -1 which is consistent with virDomainBlockStats api.
