sure, on a full 3.6 cluster. I stopped/restarted them. I restarted =
vdsmd and
libvirtd
ok..and just for the sake of completeness - what is libvirt version =
exactly? If you=E2=80=99re running <1.2.14 then your initial comment =
make a lot of sense=E2=80=A6.
Yes, el7.2 has the right one (1.2.17) but even on 7.1 it should support =
it and if it doesn=E2=80=99t it=E2=80=99s our problem we should fix in =
ovirt (similarly as we solve qemu by shipping it ourselves)
> Or how/when did you create it?
those vms have been created before uprading to 3.6, some of them from =
a blank
template, other one based on a el7 template.
