Re: [Users] Unable to run VM with "Unable to create cgroup" error message
Hi,
the only problem I could imagine is that there is really some directory
missing, but you said it is there. Fromt his point I see two things you
can try:
1) run libvirt with debugging output enabled [1]
2) try to create the directories manually
Hopefully it'll give us more information on what's wrong.

Hi everyone,
I created a Desktop VM1 with all default settings and added a 2G Disk
to the VM1 in WebAdmin.
But when I run the vm, it returns failure with the follow error
message in WebAdmin.
"VM VM1 is down. Exit message: Unable to create cgroup for VM1"
My DateCenter contains one host(with OS is CentOS 6, VDSM version is
4.9.6 and libvirt version is 0.9.4) and one NFS domain.
And The cgroup Directory have already exits on the host.
But why cannot I run the VM1?
There are some error message in VDSM log
--------
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 2087, in createXML
if ret is None: raise libvirtError('virDomainCreateXML() failed', conn=self)
libvirtError: Unable to create cgroup for VM1: No such file or directory
----------
There are some error message in libvirt log
---------
error : virNetClientProgramDispatchError:170 : Unable to create cgroup
for VM1: No such file or directory"
---------
There are log files in attachment
Best wishes,
