[libvirt] libvirt + kvm external snapshots: use case?
by Cole Robinson 29 Jul '12

29 Jul '12

Forgive my ignorance, but I'm trying to fill in some details for a Fedora feature page: https://fedoraproject.org/w/index.php?title=Features/Virt_Live_Snapshots Yet things aren't working quite as expected in my tests. I'm trying to think of this from an end user use case perspective. For example - I want to test some changes to my vm, and either throw them away, or commit them to my base disk image. - I want to have a base disk image, but have multiple snapshots with various mutually exclusive VM changes in each, like one snapshot with libvirt 0.7.0 installed, another with 0.8.0 installed. I want to switch between them (maybe those assumptions are off base to begin with) So for a running guest, I do: virsh snapshot-create-as myvm snapshot1 "snapshot1 description" --disk-only virsh snapshot-create-as myvm snapshot2 "snapshot2 description" --disk-only I make some changes that I want to discard, so I try and switch back to the older vm and want to switch back to an older snapshot state, odo: virsh snapshot-revert myvm snapshot1 But I get: 'revert to external disk snapshot not supported yet'. Hmm, that kind of invalidates all my use cases then. Additionally I don't see any API option for merging snapshots, to fold my changes in snapshot2 into parent snapshot1 or similar. I tried using snapshot-delete, but that also fails with external disk snapshots: 'deletion of 1 external disk snapshots not supported yet' Additionally, there's the --atomic option to snapshot-create-as, but it fails for guests with more than 1 snapshotable disks: 'atomic live snapshot of multiple disks is unsupported'. But isn't that what some of the recent qemu additions explicitly supposed to support (that's the impression I got from jtc)? So am I missing anything? If not, are things just not fully wired up or are there missing chunks of functionality? And what's the use case for the current impl of disk snapshoting (while I've read around and found lot's of info about the implementation side of things, not too much about intended uses)? Thanks, Cole

[libvirt] [libvirt-php] Bug(?) in getting domain resource from sub-function
by Katelyn Schiesser 28 Jul '12

28 Jul '12

Hi everyone! I ran into a rather annoying bug this evening. It appears that having a special function to connect to libvirt (in a class), like: <?php function libvirtConnect(){ return libvirt_connect('qemu+tls://'.$this->hostname.':16514/system', false); } ?> ..causes any calls to get a domain resource to be corrupted somehow, like: <?php function getDomainResource(){ $lvd = $this->libvirtConnect(); return libvirt_domain_lookup_by_uuid_string($lvd, $this->uuid); } function doSomething(){ $res = $this->getDomainResource(); libvirt_domain_create($res); } ?> This throws a warning: invalid domain pointer in virDomainGetXMLDesc However, doing everything in one function, or maunally doing a libvirt_connect(), makes everything work fine. Which is why my bug senses are tingling- or am I just not understanding how LV pointers work? libvirt_version returns: $ php -r 'print_r(libvirt_version());' Array ( [libvirt.release] => 3 [libvirt.minor] => 8 [libvirt.major] => 0 [connector.version] => 0.4.5 [connector.major] => 0 [connector.minor] => 4 [connector.release] => 5 ) Full, working test code: http://pastie.org/4347100 Thank you!

[libvirt] KVM Forum 2012 Call For Participation
by KVM Forum 2012 Program Committee 28 Jul '12

28 Jul '12

================================================================= KVM Forum 2012: Call For Participation November 7-9, 2012 - Hotel Fira Palace - Barcelona, Spain (All submissions must be received before midnight Aug 31st, 2012) ================================================================= KVM is an industry leading open source hypervisor that provides an ideal platform for datacenter virtualization, virtual desktop infrastructure, and cloud computing. Once again, it's time to bring together the community of developers and users that define the KVM ecosystem for our annual technical conference. We will discuss the current state of affairs and plan for the future of KVM, its surrounding infrastructure, and management tools. We are also excited to announce the oVirt Workshop will run in parallel with the KVM Forum, bringing in a community focused on enterprise datacenter virtualization management built on KVM. For topics which overlap we will have shared sessions. So mark your calendar and join us in advancing KVM. http://events.linuxfoundation.org/events/kvm-forum/ Once again we are colocated with The Linux Foundation's LinuxCon, Based on feedback from last year, this time it's LinuxCon Europe! KVM Forum attendees will be able to attend oVirt Workshop sessions and are eligible to attend LinuxCon Europe for a discounted rate. http://events.linuxfoundation.org/events/kvm-forum/register We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2012. http://events.linuxfoundation.org/cfp Suggested topics: KVM - Scaling and performance - Nested virtualization - I/O improvements - PCI device assignment - Driver domains - Time keeping - Resource management (cpu, memory, i/o) - Memory management (page sharing, swapping, huge pages, etc) - VEPA, VN-Link, vswitch - Security - Architecture ports QEMU - Device model improvements - New devices and chipsets - Scaling and performance - Desktop virtualization - Spice - Increasing robustness and hardening - Security model - Management interfaces - QMP protocol and implementation - Image formats - Firmware (SeaBIOS, OVMF, UEFI, etc) - Live migration - Live snapshots and merging - Fault tolerance, high availability, continuous backup - Real-time guest support Virtio - Speeding up existing devices - Alternatives - Virtio on non-Linux or non-virtualized Management infrastructure - oVirt (shared track w/ oVirt Workshop) - Libvirt - KVM autotest - OpenStack - Network virtualization management - Enterprise storage management Cloud computing - Scalable storage - Virtual networking - Security - Provisioning SUBMISSION REQUIREMENTS Abstracts due: Aug 31st, 2012 Notification: Sep 14th, 2012 Please submit a short abstract (~150 words) describing your presentation proposal. In your submission please note how long your talk will take. Slots vary in length up to 45 minutes. Also include in your proposal the proposal type -- one of: - technical talk - end-user talk - birds of a feather (BOF) session Submit your proposal here: http://events.linuxfoundation.org/cfp You will receive a notification whether or not your presentation proposal was accepted by Sep 14th. END-USER COLLABORATION One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user collaboration proposal. As an end user, this is a unique opportunity to get your input to developers. BOF SESSION We will reserve some slots in the evening after the main conference tracks, for birds of a feather (BOF) sessions. These sessions will be less formal than presentation tracks and targetted for people who would like to discuss specific issues with other developers and/or users. If you are interested in getting developers and/or uses together to discuss a specific problem, please submit a BOF proposal. LIGHTNING TALKS In addition to submitted talks we will also have some room for lightning talks. These are short (5 minute) discussions to highlight new work or ideas that aren't complete enough to warrant a full presentation slot. Lightning talk submissions and scheduling will be handled on-site at KVM Forum. HOTEL / TRAVEL The KVM Forum 2012 will be held in Barcelona, Spain at the Hotel Fira Palace. http://events.linuxfoundation.org/events/kvm-forum/hotel Thank you for your interest in KVM. We're looking forward to your submissions and seeing you at the KVM Forum 2012 in November! Thanks, your KVM Forum 2012 Program Commitee Please contact us with any questions or comments.

[libvirt] Support to transfer OVSDB:Interface stats during Live Migration
by kiran Chunduri 27 Jul '12

27 Jul '12

Hi, I was experimenting 'live migration' with libvirt (using virsh) and observed that post migration the Interface stats in 'OVSDB:Interface' table are not transferred. Only the values in 'external_ids' column seem to be synced up. The libvirt version I'm using is 0.9.11.3. The virsh command used for migration is: 'virsh migrate --live fc17-vm qemu+ssh:// 10.23.167.219/system' Is this the right behavior (or) Have I missed out on some option? Can some one please guide on the approach and the source files to look at If i need to add this support? thanks Kiran

[libvirt] [PATCH] build: update to latest gnulib, for secure tarball
by Eric Blake 27 Jul '12

27 Jul '12

Pick up some build fixes in the latest gnulib. In particular, we want to ensure that official tarballs are secure, but don't want to penalize people who don't run 'make dist', since fixed automake still hasn't hit common platforms like Fedora 17. * .gnulib: Update to latest, for Automake CVE-2012-3386 detection. * bootstrap: Resync from gnulib. * bootstrap.conf (gnulib_extra_files): Drop missing, since gnulib has dropped it in favor of Automake's version. * cfg.mk (local-checks-to-skip): Conditionally skip the security check in cases where it doesn't matter. --- I'm stoked! I figured out how to upgrade to the latest automake and make our release process secure (tested with 'make dist' on a system with insecure automake), without penalizing normal development (tested with 'make check' on the same system). * .gnulib a02ba4b...6c37e0a (76): > verify: document conflict with -Wnested-externs > maint.mk: forbid exit(-1) > fsusage: port back to Solaris > gnu-web-doc-update: fix error messages > gnu-web-doc-update: check the requirements. > maint.mk: minor simplification. > gitlog-to-changelog: VPATH build issues. > fpending: Assume AC_CHECK_DECLS_ONCE invocation, like in fpending.m4. > pthread_sigmask: fix bug on FreeBSD 9 > README-release: make it more legible > autoupdate > maint: require that each sc_... command start with "@" > maint.mk: add leading "@" to quiet new "make syntax-check" rule > autoupdate > maint.mk: new syntax check for HAVE_DECL checks > argp: make HAVE_DECL usage consistent > stat-time: relax license to LGPLv2+ > strndup: fix m4 usage error > maint: enable the sc_avoid_if_before_free syntax-check rule > gettext: do not assume '#define ... defined ...' behavior > getloadavg: clean out old Emacs and Autoconf cruft > bootstrap: let warn be like tests/init.sh's warn_ > getopt: Simplify after Emacs changed. > maint.mk: add sc_vulnerable_makefile_CVE-2012-3386 > maint.mk: _sc_search_regexp, sc_vulnerable_makefile_CVE-2009-4029: fix > getloadavg, getopt: fix commentary re configure.in > timespec: mark functions with const attributes > canonicalize[-lgpl]: handle "guessing" values when cross-building > canonicalize: make the right guess when cross-compiling to GNU > update from texinfo > timespec-sub: avoid duplicate include > bootstrap: use a more consistent error reporting scheme > sys_time: allow too-wide tv_sec > pthread: check for both pthread_create and pthread_join > parse-datetime: doc tuneup > do-release-commit-and-tag: fix the previous commit > do-release-commit-and-tag: fix typo > pthread: check for pthread_create, not pthread_join > parse-datetime: fix failure to diagnose invalid input > bootstrap: do not require now-removed build-aux/missing > alloca: add support for HP NonStop TNS/E native > fsusage: remove code not needed on non GNU/Linux systems. > fsusage: include files needed for glibc 2.6 fallback > fsusage: avoid needless check on GNU/Linux > log: Fix an autoconf >= 2.64 warning. > autoupdate > autoupdate > log10f: Fix possible configuration problem. > Fix typo in ChangeLog entry. > remove: No longer override on all platforms.
