Subject Re: how the best way to upgrade KVM hosts (Centos 6.6 to Centos 7)
Date Sat, 05 Sep 2015 07:03:43 GMT
Indeed. I will see if I can backport it to 4.5 next week. Until then, try this:

Open  "/etc/libvirt/qemu.conf" and remove this line:
"cgroup_controllers = [ \"cpu\" ]"

Then restart libvirtd and then the CloudStack agent. 

Regards, Remi
