I can only use RHEL6.

Is it a bug in libvirt ??

Hi,
 
I started the VMs with libvirt 3 days ago (17th Feb).  Now when I am trying to shutdown the domain, all my virsh command is hanging even  virt-manager remains in "connecting.."  mode and is not showing active domains.
When   I set  the libvirt debug env and call "virsh list"  it hangs in poll. Here is the log
setenv LIBVIRT_DEBUG 1 virsh list

Thanks for your help in advance.
