hi stefan.
I have setup a VM on a server with two NICs (eth0 and eth1). eth0 is
connected with vlan22 and eth1 is connected with vlan33. I then added eth0.22

respectively. When i start up the vm, the network conn

I am using qemu2.3.0 to start a guest on different linux kernel (2.6.33 and
2.6.39). The qemu command line is:
kvm -m 2g -hda guest.img -enable-kvm
Experiments show that the disk write bandwidth of the guest on 2.6.33.3 is 10
times of that on 2.6.39. The period of paio_submit (time differ

Hi all,
