Hi Everyone,

as we wrap oVirt 3.2, I wanted to check with oVirt users on what they
find good/useful in oVirt, and what they would like to see
improved/added in coming versions?


A nice feature would be to be able to migrate guests between AMD and 
Intel host machines.
KVM should be able to support it [1]. I don't know if other hypervisors 
are able/can to support this. Because oVirt aims to support different 
hypervisors it might be problematic. But I think offline migration 
should be possible.

Thanks,

can you please elaborate what do you mean by offline migration?



With offline  migration, I means the guest is not running while moving 
it from one host to another.


I have 2 host machines for testing. One is running on a AMD Opteron and 
the other Intel Xeon. Since I can not put both machines in the same 
cluster, I have specified a cluster called AMD (for the opteron) and 
another called Intel (for the xeon).
Now I would like to move a guest from the AMD machine to the Intel 
machine. Since the CPU does not match I can't.


I assume the solution for this could be a generic cluster definition. 
Something with a limited/specific cpu set equal to the qemu 
configuration -cpu qemu32 or -cpu qemu64.

I'm not aware that you can't.


Ok, now is see my problem.


you should be able to move the VM from one cluster to the other.
yes, it will see a different cpu model. why is that an issue?



To move the guest I need to edit the guest and than I can change the 
cluster.
