Re: [ovirt-users] libvirtError: Cannot get interface MTU

2017-02-10 Thread Tyson Landon 
I created a new cluster using the legacy switch type and added two fresh hosts. 
Then I shut off a VM selected the new cluster in its settings and booted it. It 
will now live migrate between hosts on the new cluster. Thanks for the help.

I am trying to migrate guests off host2 to run updates. The Switch type is OVS 
so are there any pitfalls related to changing that to legacy?

I would recommend starting from scratch, do not attempt to move from OVS to 
legacy on that version.

Please share the versions you are using (VDSM and Engine).
Have you configured at the cluster level the switch type as OVS? If so, note it 
is experimental
and we have not supported migration over OVS in early 4.1 versions.

My engine version is 4.0.5.5-1.el7.centos. The first host is using 
vdsm-4.18.21-1.el7.centos and the second is using vdsm-4.18.15.3-1.el7.centos. 
I am trying to migrate guests off host2 to run updates. The Switch type is OVS 
so are there any pitfalls related to changing that to legacy?
