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
.......
<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>
........
The problem seems to be the same uuid on both hosts,
1) is correct?
2) if is correct, how I can resolve?
Thanks a lot in advance
Umberto

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.

Should we also teach libvirt to recognize this particular UUID as
invalid, just as we already reject all 0's and all F's as bad (also
values seen from bad hardware vendors)?

Once we start going down this route, it'll never end IMHO. I've seen
so many "bad" patterns used by various vendors...
The alternate is to not use the SMBIOS uuid, but rather rely on the
fact that new hosts with SystemD, have a sane UUID generated and
recorded in /etc/machine-id
