[libvirt-users] Information needed regarding the libvirt version libvirt-1.0.6-1
by arun abhinay 23 Aug '13

23 Aug '13

Hi, We have upgraded the libvirt version from libvirt-1.0.5 to libvirt-1.0.6-1 on our linux machine. After this upgrade "virsh cpu-stats <domain>" command is not working on our HardWare. *virsh # cpu-stats test error: Failed to retrieve CPU statistics for domain 'test' error: internal error error accessing cgroup cpuacct for vcpu* ** *# cat /proc/cgroups #subsys_name hierarchy num_cgroups enabled cpuset 3 4 1 ns 0 1 1 cpu 1 6 1 cpuacct 7 3 1 memory 2 3 1 freezer 0 1 1 net_cls 0 1 1 blkio 0 1 1 * *# chkconfig --list | grep cg cgroups_mount 0:off 1:on 2:on 3:on 4:on 5:on 6:off* We have also found that there is no "cgroup" directory created by kenel under "/sys/fs/". We suspect that the 'cgroup' controllers are not mounted properly and hence the issue is observed. While using the libvirt-1.0.5 version below mentioned mount commands were sufficient to mount cgroup controllers *mkdir -p /dev/cgroup_cpuacct mount -t cgroup -o cpuacct cpuacct /dev/cgroup_cpuacct* As cgroups hieracrhy inside libvirtd has changed in libvirt-1.0.6-1, we feel that the above commands are now not sufficient. We feel we have to do some more steps get the 'cgroups' mounted properly on our hardware. Since we are new to libvirt and can you please help us by providing some pointers to fix the above issue and get cpu-stats working on our HardWare. Since we have to fix this on top priority, can you please reply as soon as possible. Please let us know if you need any further information from our side. Thanks in advance. BR Abhinay

[libvirt-users] QemuAgentCommand API documents
by Praveen Kumar 22 Aug '13

22 Aug '13

Hi, I was going through the maillist[0] and found virDomainQemuAgentCommand() support function added to python module. I also checked the API documentation and didn't able to find any pointer for this particular function. Is API documentation[1] not updated with these function details yet or I am looking to a wrong place? Another question is I am using libvirt-1.0.5.5-1.fc19.x86_64 and using virsh with qemu-agent-command I am able to execute stuff from host. but I am not able to find any API method to do that, any suggestions?

[libvirt-users] Running hypervisor upgrade problem
by Naor Shlomo 21 Aug '13

21 Aug '13

Hello experts, I tried upgrading libvirt and compiled version 1.1.1 The problem is that when I run "virsh version" I get the following output: Compiled against library: libvirt 1.1.1 Using library: libvirt 1.1.1 Using API: QEMU 1.1.1 Running hypervisor: QEMU 0.12.1 The problem is that it reports that the Running hypervisor is: QEMU 0.12.1 I wanted to upgrade everything to the latest stable so I also upgraded the qemu-kvm to 1.5.2 but for some reason the reported qemu hypervisor is left outdated. Could you please tell me why is that and how do I upgrade it to the latest? Thanks in advance, Naor

[libvirt-users] lxc-enter-namespace not supportted with python?
by hzguanqiang＠corp.netease.com 21 Aug '13

21 Aug '13

Hi, Daniel. It seems that the virsh command 'lxc-enter-namespace' encapsulates several functions just as 'virDomainLxcOpenNamespace', 'virDomainGetSecurityLabel', 'virDomainLxcEnterSecurityLabel' , 'virDomainLxcEnterNamespace', 'virFork', etc. And I found only 'virDomainLxcOpenNamespace' is provided by python package 'libvirtmod_lxc '. Does this mean that 'lxc-enter-namespace' can only be used through virsh command and not supported with python? Thanks ------------------ Best regards! GuanQiang 2013-08-21

[libvirt-users] Stop the relabeling of CD images
by Cristian Ciupitu 21 Aug '13

21 Aug '13

Hi, I'm installing the operating system for my virtual machines from CD images and I would like for libvirtd to stop relabeling the corresponding files. Since the installation media is no big secret, I have labeled the files with system_u:object_r:public_content_t:s0, but libvirtd keeps changing them to system_u:object_r:svirt_image_t:s0. It also changes the ownership to qemu:qemu. This means that I can not make the files immutable (chattr +i). The XML dump of the machine looks like this : <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/extra/Software/Linux/Fedora/Fedora-Live-Desktop-x86_64-19/Fedora-Live-Desktop-x86_64-19-1.iso'> <seclabel relabel='no'/> </source> <target dev='hdc' bus='ide'/> <readonly/> <shareable/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> I am using libvirt-daemon-1.1.1-2.fc19.x86_64. You might also find interesting bug #568935 [1]. So how do I stop libvirtd from changing the permissions of the CD images? Thank you, Cristian Ciupitu [1]: https://bugzilla.redhat.com/show_bug.cgi?id=568935

Hi, I want to create/attach two "internal" and one "host-only" interface to my node created by libvirt on ESX hypervisor. Is it possible to do so? If yes can anyone send a template of xml file? If it is not possible then is there any alternative for this? Regards, Varun
