Red Hat Bugzilla – Bug 230634
PVFB backend fails to terminate when frontend vanishes early
Last modified: 2007-11-30 17:07:42 EST
Description of problem:
When the frontend vanishes from xenstore before the connection is established,
the backend fails to terminate.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Make sure the guest has a VNC PVFB configured.
2. Start the guest (e.g. with xm create) with a kernel that lacks PVFB.
3. Shut down the guest, e.g. with xm shutdown.
Process xen-vncfb is still running for the guest.
Process xen-vncfb terminates when guest shuts down.
The steps to reproduce use a kernel without PVFB just to make them independent
of timing. The bug should also bite with a stock kernel (which has PVFB), when
the guest is shut down or destroyed quickly enough.
