#mount -o soft,timeo=2 nfs_server_ip:/root/image
2.create a image on nfs file
3.start a vm on hostA
#/usr/libexec/qemu-kvm -no-hpet -no-kvm-pit-reinjection -usbdevice tablet -rtc-td-hack -startdate now -name RHEL5U9-1 -smp 4,cores=4 -k en-us -m 4G -uuid `uuidgen` -boot c -net nic,vlan=1,macaddr=00:1a:1a:12:19:01,model=virtio -net tap,vlan=2,ifname=virtio_10_2,script=/etc/qemu-ifup,downscript=no -drive file=/mnt/rhel5.9-64.qcow2,media=disk,if=virtio,cache=off,boot=on,format=qcow2,werror=stop -cpu qemu64 -M rhel5.6.0 -notify all -balloon virtio -monitor stdio -spice host=0,ic=on,port=5930,disable-ticketing -qxl 1 -drive file=/mnt/rhel5.9-ide.qcow2,media=disk,if=virtio,cache=off,boot=off,format=qcow2,werror=stop
4.migrate guest to hostB
#migrate -d tcp:,spiceport=5930,spicehost=
5.stop nfs server, then waiting for migration complete.
6.start nfs server, perform "cont" on hostB's qemu-kvm command line.
