Unable to connect Xend with virt-manager
- by Majid Azimi
I have installed debian 6.0.1a. I have install all XEN stuff. including xen kernel, libvirtd, ... but when i want to connect xend, virt-manager shows me this:
Verify that:
A Xen host kernel was booted
The Xen service has been started
details:
Unable to open connection to hypervisor URI 'xen:///':
unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/connection.py", line 971, in _try_open
None], flags)
File "/usr/lib/python2.6/dist-packages/libvirt.py", line 111, in openAuth
if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied
here is uname output:
Linux debian 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux
and also xend and libvirtd is runnig:
root@debian:/home/mazimi# /etc/init.d/libvirt-bin status
Checking status of libvirt management daemon: libvirtd running.

and also we have group named libvirt in /etc/group
When running libvirtd with verbose mode it behaves kind of stange:
root@debian:/var/log/libvirt# /usr/sbin/libvirtd --verbose
17:26:55.841: warning : qemudStartup:1832 : Unable to create cgroup for driver: No such device or address

and waits infinitely.
