[libvirt] failed to connect to the hypervisor

[Ameya Pandit]

Hi,

I have KVM qemu installed on Fedora 12 host server.
My VMs are marked to autostart.  When I reboot my host server the
virtual machines starts but halts on its bios display screen.
If I login mannually destroy the VMs and start again, it just works
without any errors.

Can someone please help me with this issue ?
error logs I found are this :
Starting libvirtd daemon:                                  [  OK  ]
error: unable to connect to '/var/run/libvirt/libvirt-sock': No such
file or directory
error: failed to connect to the hypervisor
