CVE-2008-1944 PVFB SDL backend chokes on bogus screen updates
Last modified: 2010-12-20 16:48:35 EST
Description of problem:
When using 'xm create' to start a paravirt guest, the SDL window often
disappears part way through the boot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Configure a pv guest to use SDL graphics
2. xm create <pv guest>
3. wait for the guest to boot all the way up
I've seen the SDL window disappear on both i386 and ia64 about 20% of the time.
I see nothing suspicious in xend.log. There is no output to xend-debug.log.
The SDL window should remain present every time a paravirt guest is started.
Looks similar to bz# 217635
