Description Markus Armbruster 2006-12-21 14:25:15 EST
Description of problem:
Apparently, xend forgets pvfb configuration on restart, and upstream silently
fixed that by storing it in xenstore rather than the device object
(xen-unstable.hg changeset 13076).

How reproducible:
In theory, always.  In practice, haven't tried.  I just want to get it on the
books before the Christmas break.

Actual results:
Not eintirely obvious.  I'm guessing that save domain, restart xend, restore
domain will fail to bring the pvfb up.

Comment 2 Markus Armbruster 2007-06-12 09:16:16 EDT
The bug is real, but it affects only vncpasswd.  However, forgetting that on
xend restart is a security bug.
Comment 4 Markus Armbruster 2007-06-14 10:16:27 EDT
Patch has been reviewed and committed to the rhel-5-1-hybrid-merge branch, where
it is now awaiting to be merged into the trunk.
