Description Daniel Berrange 2006-10-23 21:07:00 UTC
Description of problem:
When migrating a guest across hosts, the paravirt vnc console does not get
activated on the destination. The VNC feature does not appear set on the
destination xend data, the VNC daemon is not started, and the vnc port is not
present in xenstored

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Find a paravirt guest running the VNC console
2. Verify the VNC console is active & working
3. Migrate the guest to an alternate host
4. Try and connect to the VNC console
Actual results:
No VNC server is available for the migrated guest

Expected results:
VNC server is available on the destination host

Additional info:
Very likely a similar root cause to bug 211911 (VNC missing after
suspend/restore cycle).

Comment 2 Daniel Berrange 2006-10-26 21:11:33 UTC
The migration codepath does indeed go through the same path as restore, so
fixing the restore problem, should fix VNC for migration too.

Comment 3 Daniel Berrange 2006-12-19 18:32:17 UTC
This should now be operating correctly, as a result of the PVFB upgrade tracked
by bug 218050.
