[libvirt-users] 答复: 答复: Virsh command hanging

Wed Feb 22 10:20:31 UTC 2017

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.
