>Summary: linux virtio drivers won't work after runing save/restore

Initial Comment:
I tried to save/restore a rhel5u1 guest with virtio drivers.
Save the guest is ok.
But it failed when run restore.

Here is the command I am using:
[root@vt-nhm1 ~]# qemu-system-x86_64 -m 512 -smp 1 -net nic,macaddr=00:16:3e:0f:be:84,model=virtio -net tap,script=/etc/kvm/qemu-ifup -hda /root/ia32p_rhel5u1.img -drive file=/media/root/ia32p_suse10u2.img,if=virtio -incoming file://share/xvs/var/sr123
Migration failed rc=201

The command i pasted in previous commend is wrong.
I retested it with using following command:
qemu-system-x86_64 -m 256 -net nic,macaddr=00:16:3e:10:4d:f1,model=virtio
-net tap,script=/etc/kvm/qemu-ifup -hda /share/ia32p_rhel5u1.img -drive
file=/mnt/sda1/ia32p_rhel4u1.img,if=virtio -incoming file:///tmp/ddd

The problem is linux virtio drivers won't work after runing save/restore.
The reproduce steps are:
1. booting a linux guest with virtnet and virtblk.
2. enable virtnet and mount virtblk
3. ping another host in the guest, and do some operations on the virtblk
partition, like copy a big file to the disk.
4. save the guest
5. restore the guest.
What I am now seeing is either virtnet and virtblk will stop working after
running restore.
