[libvirt] Is virConnectListDefinedDomains broken?
by Hongming Xiao 10 Jul '09

10 Jul '09

Hi, list, Recently, I upgraded my system to Xen 3.3.1 (from Xen 3.0.3). After this, I found that virConnectListDefinedDomains no longer works. The problem can be reproduced by executing "virsh list -all" - those defined but inactive domains are not be returned. Has libvirt API been tested against Xen 3.3.1? Can this problem be fixed by upgrading libvirt to version 0.6.5? What is the best approach to address this issue? Thanks in advance, Eddy OS: CentOS 5.3 Xen: kernel-xen.x86_64 2.6.18-128.1.14.el5 installed kmod-drbd83-xen.x86_64 8.3.0-3 installed xen.x86_64 3.3.1-0 installed xen-libs.x86_64 3.3.1-0 installed libvirt: libvirt.x86_64 0.4.4-3 installed libvirt-python.x86_64 0.4.4-3 installed python-virtinst.noarch 0.300.2-12.el5 installed virt-viewer.x86_64 0.0.2-2.el5 installed

[libvirt] sound does not work for me
by Gene Czarcinski 10 Jul '09

10 Jul '09

I must must be doing something wrong because all the messages, etc. I have found says that sound works for guests. I let the guest's virtual sound device default to ES1370. I have tried f11 32 bit, f11 64 bit, and win2k and sound just does not work for any of them. I tried this with F11 64 bit host (libvirt 0.6.2) and a different F11 64 bit host with preview packages installed (libvirt 0.6.5) ... sound works on each of the host system but does not work for an guests. With a F11 64 bit guest, the sound preference applet shows the output device os "null". Also, doing "lspci" shows NO sound device. OK, what is going on? Gene

[libvirt] fix two "make syntax-check" failures

[libvirt] libvirt repositories mirrored on gitorious
by Daniel P. Berrange 10 Jul '09

10 Jul '09

FYI, I have created a libvirt project on gitorious which has a mirror of the master branch of the libvirt.git repository. This mirror is *readonly* and updated automatically every 15 minutes. The purpose of this mirror is to allow people to easily publish their personal libvirt working repos to the world. The master upstream repository for libvirt does not change, it will remain on http://libvirt.org/git The main project under which libvirt repos will be hosted is at this URL: http://gitorious.org/libvirt You'll see the master libvirt.git repository there, and if you look at the right hand side, you'll see myself & Mark have both got clones for our staging repos, and topic branches within those clones for various patchsets we're working on If you want to publish your own patches simply signup for gitorious, go to the libvirt repository http://gitorious.org/libvirt/libvirt and select the 'Clone this repository on gitorious' link. A short while later you'll have your own personal clone where you can publish work you are doing on libvirt. Use of this is by no means compulsory, and doesn't change how you should submit patches to libvirt. They should still all be emailed to this list for review.

[libvirt] [PATCH 0/4] Use a unix socket for the qemu monitor
by Mark McLoughlin 09 Jul '09

09 Jul '09

Hi, In order to support qemu NIC hotplug, we're planning on sending tap file descriptors across the monitor to qemu. If that sounds like magic, it is! One of the most mystical and magical unix features around. See SCM_RIGHTS in unix(7). The upshot is that we need to switch to using a unix socket for the qemu monitor. This patch series does just that, while handling the tricky scenario where you start a vm with an old version of libvirtd, update to a newer version and restart libvirtd. See also: https://fedoraproject.org/wiki/Features/KVM_NIC_Hotplug Cheers, Mark.

[libvirt] More then one pci device possible with libvirt and pci passthrough?
by Mirko Raasch 09 Jul '09

09 Jul '09

Hi, i want to use more then one pci card in my debian guest. But when i start the guest, the log says: libvirtd: 15:44:55.459: warning : pciTrySecondaryBusReset:483 : Other devices on bus with 0000:05:01.0, not doing bus reset With "/usr/bin/qemu-system-x86_64 -m 512 -name test -hda /media/vm/test.img -boot c -vnc :2 -k de -pcidevice host=05:01.0 -pcidevice host=05:02.0 -pcidevice host=05:03.0" there seems to be no problems. How can i start my guest with three pci devices passed through and libvirt? My hostdev section in the xml looks like this: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x05' slot='0x01' function='0x0'/> </source> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x05' slot='0x02' function='0x0'/> </source> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x05' slot='0x03' function='0x0'/> </source> </hostdev> Greetings Mirko

[libvirt] F11 and KVM Migrations
by Scott Baker 09 Jul '09

09 Jul '09

I have two host machines on the same subnet, and I have /var/lib/libvirt/images shared between the two via NFS. I'm trying to do a "migration" from one host to another and I'm getting an error. virsh # migrate --live Narwhal qemu+ssh://10.1.1.1/system error: operation failed: failed to start listening VM That's from the host running the VM to the new host. I'm assuming you have to do a "push" migrate, not a "pull"? Where can I look next to figure out why it didn't work? -- Scott Baker - Canby Telcom System Administrator - RHCE - 503.266.8253

[libvirt] more options for virt-manager
by Gene Czarcinski 09 Jul '09

09 Jul '09

I noticed that the command line qemu and qemu-kvm offer a number of options such as using vmware display and addition sound card emulation as compared to that when using virt-manager. Are there any plans to add these as options to virt-manager? As a more general question, is there some document which describes the plans, roadmaps, etc. for Fedora Virtualization (or should I say Linux Virtualization since it does apply to other distributions as well)? I pick up tid-bits in various messages and bug reports such as libvirt supporting vmware and "pool storage" providing some improvements but I do not have an overall picture as to what is planned. While developers may do some things sooner rather than later because they are easy to do, we users may have some preferences as to what features/capabilities are more important to us than others.
