[Qemu-devel] QEMU 0.15.1 Linux

[Qemu-devel] QEMU 0.15.1 Linux

[Gus Zernial]

I have Kubuntu 11.10 Oneiric with standard 3.0.0-12-generic kernel on an AMD Phenom II X6 box.
I've been running Windows 7 guest under qemu ....

$ /usr/bin/qemu-system-x86_64 -version
QEMU emulator version 0.14.1 (qemu-kvm-0.14.1), Copyright (c) 2003-2008 Fabrice Bellard

$ sudo /usr/bin/qemu-system-x86_64 -boot c -drive 
file=~/Win7.img,if=virtio -m 4096 -smp 1,cores-6 -net 
nic,vlan=0,macaddr=52:54:db:7f:0c:3d,model=virtio  -net tap -vga cirrus 
-soundhw hda -cdrom /dev/sr0

This boots the Windows 7 client, no problems

Then I installed qemu-0.15.1, compiled and installed from source and ran the same qemu startup command 
line with the new version

$ /usr/local/bin/qemu-system-x86_64 -version
QEMU emulator version 0.15.1, Copyright (c) 2003-2008 Fabrice Bellard

$ sudo /usr/local/bin/qemu-system-x86_64 -boot c -drive 
file=~/Win7.img,if=virtio -m 4096 -smp 1,cores-6 -net 
nic,vlan=0,macaddr=52:54:db:7f:0c:3d,model=virtio  -net tap -vga cirrus 
-soundhw hda -cdrom /dev/sr0

This results in Windows BSOD. I tried installing libvirt-bin_0.9.6~oneiric-2ubuntu5_amd64 to see if that would
help, but it didn't. It's possible there's some prerequisite or compile option for the new version, not sure?

Can someone tell me what's wrong and/or how to fix?


Thx, Gus

This part is important - you had qemu-kvm, which is slightly different
from...

...plain qemu you compiled. Download qemu-kvm from

First of all, thanks to Jernej Simon for the response which pointed out my mistake

regards qemu vs qemu-kvm, and the pointer to the correct version. This solved my 
problem.

I have another question regards graphics driver for the Win7 client. I would like to
use the VMware SVGA 3D (WDDM) driver on the client, which would give me Windows 
Aero and potentially better graphics performance, but when I install it in Windows I get 
the bang symbol in the device manager, and the message that the driver has been 
turned off.

Is this driver supported in QEMU 0.15.1, and if so how do I get it to work? If not,
is there some alternative with the capability I mention?

Thx, Gus

The VMWare SVGA driver is reverse-engineered from the Linux/X VMWare
driver, and as such only supports what the X driver does. There's no
3D acceleration, and while at least the VMWare SVGA driver for XP does
load, it has graphical glitches, and is in my experience actually
slower than plain VESA driver.
