Thanks Wanglm for your responses.
Can anyone else has any info about how to resolve such problems. Is this an
issue fixed in higher version of libvirt ? Here all my virsh commands are
hanging which I think due to hang in libvirt-daemon.
Can restarting libvirt-domain is fine ? What all it impacts ?
RegardsAbhishek

主题: [libvirt-users] Virsh command hanging Hi, I started the VMs withlibvirt
3 days ago (17th Feb). Now when I am trying to shutdown thedomain, 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 inpoll. Here is the log setenv LIBVIRT_DEBUG 1virsh list
