Hi all,

When I start libvirt-bin on my Debian 5 host, I get the following error/warnings:

09:55:09.752: error : udevStrToLong_ui:78 : Failed to convert '0a' to unsigned int 09:55:09.770: warning : qemudStartup:1099 : Unable to create cgroup for driver: No such device or address 09:55:10.150: warning : lxcStartup:1755 : Unable to create cgroup for driver: No such device or address

A little Google’ing tells me cgroup must be created and mounted. However, when I try these instructions, all I get is:

Is the syntax perhaps a little different for Debian?

addition:

dmesg shows that some cgroup subsys are initialized on bootup:
