[Qemu-discuss] Very slow HD-access

[Ralf Ramsauer]

Hi folks!

I'm trying to set up a Windows 7 VM ( alternatively XP ). Everything 
works fine except of the hard drive access, it's very slow. It doesn't 
matter if i use the virtio drivers or not. The R/W speed is about 2MB/s.

If i run the hd-image in tmpfs, it's very fast ( damn fast ;-) ), but if 
i boot the image from my harddrive, it's much to slow.

I'm using qemu-kvm on an intel core-i7 processor ( vt-technology activated )

Does anyone have any suggestions?

Thanks a lot!

Ralf
