Migrating from A to B, then the other way around,
 all tests (RHEL5-32/64 on kvm-83-105.el5_4.13/18) passed.

host A: 10.66.91.175
host B: 10.66.91.176
AMD Phenom(tm) 9600B Quad-Core Processor

CLI:
/usr/libexec/qemu-kvm -m 2048 -smp 2 -drive file=/mnt/f12_nfs/tmpRHEL5-64.qcow2,if=ide,cache=off,boot=on -net nic,model=rtl8139,vlan=1,macaddr=DE:AD:BE:EF:20:62 -net tap,vlan=1,script=/etc/qemu-ifup -boot c -uuid 2de75016-3ef0-4e54-9b32-1d747f85709b -usbdevice tablet -no-hpet -rtc-td-hack -no-kvm-pit-reinjection -monitor stdio -notify all -cpu qemu64,+sse2 -balloon none -vnc :1

Inside guest use "ssh $hostip date -u; date -u" to get host time and its time.
