Hi,
I use qemu's kvm feature and successfuly installed Windows 7 in it.
Everything works quite well except the graphics performance being very poor.
When I move the cursor it starts flickering ('lagging') and I can't set the resolution fitting my laptop screen with a native resolution of 1366x768. (So currently using 1024x768 in the VM)
I start qemu with -vga vmware.
command I use for starting qemu:
qemu-system-x86_64 -enable-kvm -machine type=pc,accel=kvm -cpu host -vga vmware -full-screen -k de -usb -usbdevice tablet -m 3072 /path/to/image.qcow2
Is there a way to fix this??

I think the best graphic performance for qemu is currently achieved by using spice. http://www.linux-kvm.org/page/SPICE http://spice-space.org/
But the last time I tried it it was still a bit tricky to get to run correctly.

I run my Windows VMs in qemu with the -nographic option and connect to them using FreeRDP. The mouse cursor is then drawn by the host and the responsiveness is quite good in general.

I use rdesktop to connect, but otherwise same here.

Okay I tried to set it up with -nographic and rdesktop but I dont know how to retrieve my vm's ip address for connecting with rdesktop.
Any ideas how to get this working, maybe post examples? :s

Spice and QXL generally gave me the best perfomance, but Spice bugs out with gnome-keyring on Xfce at least. It requires to enter password for several times before virtmanager segfaults. However, on KDE it worked just fine, perfomance was extraordinary (Windows XP guest).

Finally got it working now, performance is surprisingly good!!!
I used to have Windows 7 Home Premium, then I discovered you cannot remote-connect to Home Prem as this version lacks that feature
So I got me Ultimate 64bit and it works.
I start the qemu vm with:
qemu-system-x86_64 -enable-kvm -machine type=pc,accel=kvm -cpu host -nographic -k de -usb -m 4096 -net nic -net user,hostfwd=tcp::3389-:3389 /home/kanikuly/Pictures/ISO/Win7Ult64Bit.qcow2
and rdesktop with:
rdesktop -g 100% -E -D -K -P -f -z -x b -r sound:off -a 32 -u *** -p *** localhost
