hi at all,

I did:
virsh # start win2008
Domain win2008 started
virsh # list
Id Name State
----------------------------------
1 win2008 running
virsh # migrate --live win2008 qemu+ssh://host2/system
error: internal error Attempt to migrate guest to the same host
00010203-0405-0607-0809-0a0b0c0d0e0f
if I type on both hosts:
host1
virsh # sysinfo
.......
<system>
<entry name='manufacturer'>Supermicro</entry>
<entry name='product'>X9SCL/X9SCM</entry>
<entry name='version'>0123456789</entry>
<entry name='serial'>0123456789</entry>
<entry name='uuid'>00010203-0405-0607-0809-0A0B0C0D0E0F</entry>

The problem seems to be the same uuid on both hosts,
1) is correct?
Yes, your hardware vendor is being very very bad :-(
2) if is correct, how I can resolve?
You could complain to the hardware vendor, but I rather doubt
that they would ever do anything about it.
So, libvirtd provides a way to override the default host UUID,
by setting 'host_uuid' in /etc/libvirt/libvirtd.conf, which
should make the migration sanity check pass.
