vmwarevga doesn't work: "get_dirty_pages returned -2"

[Andreas Winkelbauer <andreas.winkelbauer@gmx.at>]

hi,

I tried using the -vmwarevga switch but I didn't succeed. I've tested it 
with kvm-snapshot-20080218, kvm-60 and kvm-61.

as soon as the VM (guest os is windows xp) switches from text mode to 
graphics mode lots of messages "kvm: get_dirty_pages returned -2" scroll 
by on the console. after a while (but still while boot up) the VM 
crashes with stop error (blue screen) 0xEA (and says that something 
might be wrong with framebuf).

if I start the VM with -no-kvm  I don't see those messages in the 
console. the guest os boots up, but crashes quite soon with a stop error 
(blue screen) 0x7F.

my CPU is an intel core 2 duo (mobile).

uname -a output:
Linux nbwina2.local 2.6.23.15-80.fc7 #1 SMP Sun Feb 10 17:29:10 EST 2008 
i686 i686 i386 GNU/Linux

i start the VM with the following command:
su -c '/usr/local/kvm-61/bin/qemu-system-x86_64 ~/vm/xp.qcow2 -m 1024 -k 
de -usb -localtime [-vmwarevga]'

does -vmwarevga work for anyone (with windows as guest os)? what 
information do you need to track down the issue?

btw: the -vmwarevga switch should be added to the usage output of qemu.

bye,
Andi
