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

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?

If so, note it is experimental and we have not supported migration over OVS in early 4.1 versions.
