Comment 5 Vivek Goyal 2009-07-28 17:22:08 UTC
Committed in 89.7.EL . RPMS are available at http://people.redhat.com/vgoyal/rhel4/

Comment 7 Binbin Yu 2010-12-20 03:12:29 UTC
verify this bug on rhel4.8 i386 pv guest with 89.32.EL

Comment 8 Binbin Yu 2010-12-20 06:33:56 UTC
More details as follows, for bug verification.

Version-Release number of selected component (if applicable):
host: rhel5.5-32bit
xen-3.0.3-120.el5
kernel-xen-2.6.18-233.el5
guest: rhel4.8 32bit-pv, with kernel updated to 89.32.EL

 

Steps to verify:
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
4. if the sdl window remains present when the paravirt guest is started, xm shutdown <pv guest> and repeat step2~4 20 times.

useful scripts to do this loop operation:
#!/bin/sh
x=1
while((x<=20))
do
   echo this is the $x th time
   xm create /etc/xen/rhel4.8-32-pv.cfg
   echo boot over
   sleep 70
   echo sleep over and shutdown guest
   xm shutdown rhel4u8-32-pv
   echo shut over
   sleep 30
   echo sleep over and repeat to boot
   let x=x+1
done



Actual results:
The SDL window remains present every time a paravirt guest is started.


Additional info:
no reproduce this bug
