[lxc-users] LXC 1.0.0 - lxc-start: command get_cgroup failed to receive response

[Phiho Hoang]

Dear List,

I got this problem with lxc built from git source code, cloned May 25.

A similar issue was closed on Mar-27:

https://github.com/lxc/lxc/issues/189

FWIW, lxc 1.0.3 installed with

$ sudo apt-get install lxc

does NOT have this problem

Is this a known issue or it's just my environment?

Please find appended below the console output.

Best regards,

PhiHo
