Description of problem:
(copy from bug 553249#c11 ~ 553249#c14)
there are 15 window xp guest running simultaneously. connecting by vnc.
10 of them are loaded by iometer and cpuhog.
the host is Intel Core(TM)2 Quad Q9400, 4cores. (detail in additional infor )

several hours later. in guest. a warning dialog "Display Driver Stopped Responding" pop up. and finally guest BSOD.(log will upload )

CLI :
root      6669  3957 64 Jan19 pts/0    01:23:18 /usr/libexec/qemu-kvm -m 1024

-vnc :1 -vmchannel di:0200,tcp:0:7890,server,nowait -drive
file=/data/t200/test,if=ide -name t200:1


when I test 5 vms with vnc,all vms are healthy in the 12 hour testing.
when I test 15 vms with spice, vms also healthy in the 36 hour testing.

Comment 4 Gerd Hoffmann 2010-01-26 08:42:04 UTC 
What kind of tests do the iometer instances run?  Network?  Disk?  Both?
Was a vnc viewer connected while running the tests?

only Disk testing . read/write, QD from 1 to 32.
and vnc is connecting during whole test.
Comment 9 RHEL Program Management 2011-01-11 20:29:10 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.
Comment 10 RHEL Program Management 2011-01-11 22:49:12 UTC 
This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.
Comment 11 Dor Laor 2011-04-06 12:17:14 UTC 
Not sure if it is fixable, MS has a watch dog timer, if the host is too loaded we won't be schedule the guests fast enough. We need to find the registry setting to disable it and state that over release notes (similar of rhel6 as well)
Comment 12 Vadim Rozenfeld 2011-04-06 12:49:19 UTC 
Please try disabling the display watchdog.
