[libvirt] libvirt can't get capablities
by Li Zhang 04 Jul '12

04 Jul '12

Hi, I have suffered several times on both x86 machine and power machine. When we want to use libvirt to create on VMs, it reports "unknown OS type hvm". We can't get <guest> capabilities. The log is as the following(log_level=1): 2003-01-02 01:21:39.895+0000: 12214: error : virDomainDefParseXML:8491 : unknown OS type hvm 2003-01-02 01:21:39.896+0000: 12214: error : virDomainDefParseXML:8491 : unknown OS type hvm 2003-01-02 01:22:00.135+0000: 12207: error : qemuCapsComputeCmdFlags:1218 : unsupported configuration: this qemu binary requires libvirt to be compiled with yajl 2003-01-02 01:22:13.342+0000: 12207: error : qemuCapsComputeCmdFlags:1218 : unsupported configuration: this qemu binary requires libvirt to be compiled with yajl 2003-01-02 01:22:13.347+0000: 12204: error : qemuCapsExtractVersion:1576 : internal error Cannot find suitable emulator for ppc64 2003-01-02 01:22:13.351+0000: 12205: error : qemuCapsExtractVersion:1576 : internal error Cannot find suitable emulator for ppc64 2003-01-02 01:22:13.355+0000: 12207: error : qemuCapsExtractVersion:1576 : internal error Cannot find suitable emulator for ppc64 2003-01-02 01:22:13.355+0000: 12208: error : qemuCapsExtractVersion:1576 : internal error Cannot find suitable emulator for ppc64 2003-01-02 01:22:13.357+0000: 12206: error : qemuCapsExtractVersion:1576 : internal error Cannot find suitable emulator for ppc64 I search online and find one similar issue from Redhat bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=509337 Is there any solution to avoid this problem? Any idea? -- Best Regards Li IBM LTC, China System&Technology Lab, Beijing

[libvirt] [Patch v2] vmware: detect when a domain was shut down from the inside
by Jean-Baptiste Rouault 04 Jul '12

04 Jul '12

This patch adds an internal function vmwareUpdateVMStatus to update the real state of the domain.

[libvirt] Release of libvirt-0.9.13

04 Jul '12

Okay the new release is out and available as uauls at ftp://libvirt.org/libvirt/ along with rpms generated on Fedora16, the git tree is tagged too.

[libvirt] [PATCH] qemu: add rbd to whitelist of migration-safe formats
by Josh Durgin 03 Jul '12

03 Jul '12

QEMU (and librbd) flush the cache on the source before the destination starts, and the destination does not read any changeable data before that, so live migration with rbd caching is safe. This makes 'virsh migrate' work with rbd and caching without the --unsafe flag.

[libvirt] sanlock on F17
by Dave Allan 02 Jul '12

02 Jul '12

I just tried to set up sanlock on F17 using the instructions at http://libvirt.org/locking.html, but libvirtd refuses to start with the sanlock error in the logs: Jun 29 19:56:20 nienna sanlock[8423]: 19846 open error -13 /var/lib/libvirt/sanlock/__LIBVIRT__DISKS__ I confirmed that user sanlock can create, read and write files in /var/lib/libvirt/sanlock The only thing I can think of that's slightly odd about my setup is that I'm only concerned with the local machine, so that directory is not an NFS mount. Anybody have any thoughts on what's going wrong here? TIA, Dave
