PostPosted: Thu Jun 13, 2013 12:37 am    Post subject: [solved] Updated libvirt - can't create vcpu cgroup Reply with quote

I just updated my libvirt today. I can no longer start my VMs. I'm using qemu+KVM.

What is required to allow the VMs to work again? I see no "vcpu" cgroup in the kernel.

Had the same problem and after googling and trying for hours, I finally noticed these peculiar warning messages when beginning to emerge libvirt (again):
Code:

 * Checking for suitable kernel configuration options...
 *   CONFIG_CGROUP_FREEZER:      is not set when it should be.
 *   CONFIG_CGROUP_DEVICE:       is not set when it should be.
 *   CONFIG_CGROUP_CPUACCT:      is not set when it should be.
 *   CONFIG_CGROUP_PERF:         is not set when it should be.
 *   CONFIG_NET_CLS_CGROUP:      is not set when it should be.
 *   CONFIG_CPUSETS:     is not set when it should be.
 *   CONFIG_RESOURCE_COUNTERS:   is not set when it should be.
 *   CONFIG_UTS_NS:      is not set when it should be.
 *   CONFIG_IPC_NS:      is not set when it should be.
 *   CONFIG_DEVPTS_MULTIPLE_INSTANCES:   is not set when it should be.
 *   CONFIG_MEMCG:       is not set when it should be.
 *   CONFIG_MEMCG_SWAP:  is not set when it should be.
 *   CONFIG_MEMCG_KMEM:  is not set when it should be.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.


I must have activated cgroups in the kernel but not half of a dozen necessary sub-options, which you can find here:
Code:

     -> General setup                                                                                                             
       -> Control Group support


Fixed. I wished those warnings were assembled at the end of the emerge, not at the beginning!

If this fixed your problem, too. Please don't forget to add "[SOLVED]" to the thread title.

Cheers!

I have all of those options set, but still no cigar...

I have all of them set, rebuild libvirt and still nothing... The same error ...

Cheers everyone !

This did work for me.

I think this is silly, however - I don't want cgroups. I'm just using KVM/Qemu. Than again, I guess I don't have to use libvirt.
