<p>Hello</p>
<p>when I tried to migrate a VM from on virtuozzo 7 host to an
other one I get a CPU capabilities not provided by destination<br>
</p>
<p># prlctl migrate myVM root@olympos -v 16<br>
Logging in<br>

Failed to migrate the VM: Operation failed. Failed to execute the
operation. (Details: the CPU is incompatible with host CPU: Host
CPU does not provide <b>required features: hle, rtm, rdseed, adx,
smap, 3dnowprefetch</b>)<br>

</p>
<p>indeed those capabilities don't show up in the lshw on the
destination host (cf PS below )</p>
<p>alhtough myVM doesn't seem to require those capabilities : <br>
</p>
<p># virsh edit myVM<br>

</cpu></p>
<p>1) Is it libvirt or virtuozzo (prlctl) that complains about that
? <br>
</p>
<p>2) how can I tell it to forget about those capabilities ? <br>
</p>
<p>3) should I edit myVM properties with virsh edit or prlct or
virt-manager ? <br>
</p>
<p>4) are they all compatible (on can read change done by the other
) ? <br>
</p>
<p>Thanks . <br>
</p>
<p>PS : CPU hardware capabilities on source host :<br>
