Dear all
Does the current version of libvirt support the new cgroup v2 ?
I am running KVM qemu VMs on Ubuntu with linux Kernel 4.18 with cgroup v1
and I would like to use Cgroup v2 but we I mount cgroup v2 the libvirt
virtualization daemon fail to start with error message that it cant create
cgroup /system.slice/libvirtd.service no such file or directory.
Hi Asraa,
Cgroups V2 is supported since libvirt 4.9.0 for cpu, cpuacct, io, memory
controllers.
In libvirt 5.2.0 we added support for cpuset with kernel 5.0.
There is still no support for devices controller but that one is not
mandatory to run KVM/QEMU VMs as there is a bug in kernel that leaks
some resources.
