[libvirt] [RFC][scale] new API for querying domains stats
by Francesco Romani 13 Aug '14

13 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.
