hi at all, i'm trying to migrate a vm between two host but fails, this is what 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> <entry name='sku'>To be filled by O.E.M.</entry> <entry name='family'>To be filled by O.E.M.</entry> </system> ........
host2 virsh # sysinfo

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.
