Description Jan Lieskovsky 2008-04-21 10:41:55 UTC
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):

How reproducible:

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
Actual results:
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.

Expected results:
The SDL window should remain present every time a paravirt guest is started.

Additional info:

Looks similar to bz# 217635
