Hi Folks,
I am trying to do Live HVM migration on Intel VT (x86_64) platforms. The HVM save on the source machine completes without error but the destination machine restore fails with the following error in the qemu-dm.log
file. the xend.log doesn't contain any errors. Below are the details. Is this a known problem? Does anyone know how to fix this?
I really appreciate your help.
[root@vt1 xen]# cat qemu-dm-5.log
