[libvirt-users] hangs in libvirt function virLogMessage

[Parakkal, Navin S]

Hi,
  We are hitting a deadlock on libvirt on 0.9.4 version. Can someone help us ? 

1) Is there any way to specify timeout for all the calls made by libvirt especially virConnectOpenReadOnly

2) Does virCommandRunAsync always fork a new process ?
