Description of problem:

Each time my Fedora/i386 guests attempt to poweroff or reboot I get this:

Comment 1 Jeremy Katz 2007-11-30 16:31:57 UTC 
What host kernel?  And Intel or AMD processor?
Comment 2 Lubomir Kundrak 2007-11-30 16:36:52 UTC 
kernel-2.6.23.1-49.fc8

Comment 3 Jeremy Katz 2007-11-30 16:46:09 UTC 
Reboot on Intel requires some real mode emulation that's only done with newer
kernel pieces.
Comment 4 Lubomir Kundrak 2007-11-30 16:57:07 UTC 
You mean "newer" in sense relative to my kernel-2.6.23.1-49.fc8? That means that
my problem will go away once new kernel is ought, right?
Comment 5 Jeremy Katz 2007-11-30 17:05:08 UTC 
Yep, it should
Comment 6 Lubomir Kundrak 2008-02-19 08:12:45 UTC 
Closing this, no longer happens.
