[libvirt] PATCH: 0/25: Full thread support for libvirt public API
by Daniel P. Berrange 10 Mar '09

10 Mar '09

This patch series is (mostly) aimed at providing full support for threads in the libvirt API. Specifically we remove the restriction that a single virConnectPtr is tied to a thread. Multiple threads can safely use the same object (provided one doesn't free it behind another's back :-P ) This is tested to compile on Linux + Win32 (MinGW), hopefully doesn't break Solaris, but I'll be testing that soon too. I've tortured the patches in various nasty ways are they're now stable enough to let loose and probably merge for wider testing. It'll probably be easier to just fix future problems in tree, rather than maintain this patchset longer. The full patchset is also available here http://berrange.fedorapeople.org/libvirt-threads-2009-01-13/ Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] OCaml libvirt bindings 0.6.1.0 released
by Richard W.M. Jones 10 Mar '09

10 Mar '09

http://libvirt.org/ocaml/ Not a lot of change, since the bindings are pretty much stable now. The main change, and reason for this release, was that since CVE-2008-5086 the virDomainBlockPeek and virDomainMemoryPeek bindings now require a read/write libvirt connection. This broke mlvirsh and virt-df which were requesting a read-only connection. I have now changed this (thanks David Lutterkort for pointing out the problem). Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines. Tiny program with many powerful monitoring features, net stats, disk stats, logging, etc. http://et.redhat.com/~rjones/virt-top

[libvirt] [Patch] Fix detach tap device on Xen3.3.1
by Takahashi Tomohiro 10 Mar '09

10 Mar '09

Hi, I made the patch that corrected the following problem. It is that when I executed the "virsh detach-disk" command on Xen3.3.1, Libvirt could not detach tap device and output the following error message. # virsh detach-disk Fedora xvdd libvir: Xen Daemon error : POST operation failed: xend_post: error from xen daemon: (xend.err 'Device 51760 not connected') The cause of this problem is incompatible of Xen3.3.0 and Xen3.3.1. I think Xen specific was changed by the following patch. http://xenbits.xensource.com/xen-3.3-testing.hg?rev/e0e17216ba70 If you have any comments, please suggest me.

[libvirt] libvirt 0.6.1 not playing well with RHEL5.2 lokkit
by Charles Duffy 09 Mar '09

09 Mar '09

Howdy. I'm running RHEL5.2, and libvirt 0.6.1. I don't use the distro-provided firewall (system-config-securitylevel-tui-1.6.29.1-2.1.el5) and have it completely disabled, but libvirt appears to be having some trouble ascertaining as much: > libvirtd: 14:05:42.807: warning : Failed to read /etc/sysconfig/system-config-firewall > last message repeated 2 times > kernel: fvtebr0: Dropping NETIF_F_UFO since no NETIF_F_HW_CSUM feature. > kernel: fvtebr0: starting userspace STP failed, starting kernel STP > libvirtd: 14:06:34.825: error : internal error '/usr/sbin/lokkit --nostart --custom-rules=ipv4:filter:/var/lib/libvirt/iptables/filter/INPUT.chain' exited with non-zero status 1 and signal 0: --custom-rules=ipv4:filter:/var/lib/libvirt/iptables/filter/INPUT.chain: unknown option > libvirtd: 14:06:34.825: warning : Failed to run '/usr/sbin/lokkit --custom-rules=ipv4:filter:/var/lib/libvirt/iptables/filter/INPUT.chain': Invalid argument > libvirtd: 14:06:34.828: error : internal error '/usr/sbin/lokkit --nostart --custom-rules=ipv4:filter:/var/lib/libvirt/iptables/filter/FORWARD.chain' exited with non-zero status 1 and signal 0: --custom-rules=ipv4:filter:/var/lib/libvirt/iptables/filter/FORWARD.chain: unknown option > libvirtd: 14:06:34.828: warning : Failed to run '/usr/sbin/lokkit --custom-rules=ipv4:filter:/var/lib/libvirt/iptables/filter/FORWARD.chain': Invalid argument > libvirtd: 14:06:34.831: error : internal error '/usr/sbin/lokkit --nostart --custom-rules=ipv4:nat:/var/lib/libvirt/iptables/nat/POSTROUTING.chain' exited with non-zero status 1 and signal 0: --custom-rules=ipv4:nat:/var/lib/libvirt/iptables/nat/POSTROUTING.chain: unknown option > libvirtd: 14:06:34.831: warning : Failed to run '/usr/sbin/lokkit --custom-rules=ipv4:nat:/var/lib/libvirt/iptables/nat/POSTROUTING.chain': Invalid argument

[libvirt] FileSystem Creation for Logical Storage Volume
by Martin Gajdos 08 Mar '09

08 Mar '09

Hi there As I haven't found this information anywhere else, I'm trying this mailing list. I would like to know if it's possible to create a filesystem (ext3 for e.g.) along with a storage volume with libvirt. The volumes are located on a remote system. So is there function in libvirt for this? and if not, what would be the way to go? Thanks Martin Gajdos

[libvirt] Libvirt audio xml format
by Simon Lambourn 07 Mar '09

07 Mar '09

Hi, excuse the possible dumb question from a new KVM/Libvirt user - I'm very impressed overall but struggling to work out how to define an audio device in the libvirt xml. I have a virtualised windows XP up & running, now want to add an audio device. I can see how to do it in kvm and I believe audio devices are now supported in libvirt, but could not find documentation on how to write the xml. System is Ubuntu 8.10 on AMD64. Thanks in anticipation.
