Summary: live migration fails with emulated scsi drive

Initial Comment:
CPU model: Intel(R) Xeon(R) CPU           L5335
KVM version 88
host kernel: centos 2.6.18-128.4.1.el5
guest: Tried both centos 4.8 - 32bit latest kernel and centos 5.3 64 bit, same kernel as above

Live migration will give errors and stop io to the disk when using an emulated scsi drive on the guest.  It does not fail when using an ide drive.  I get the following errors:
