[ovirt-users] Re: Problems with OVN

One way is to set the interfaces on the vm's to use dhcp. The ovn dhcp is set to use the maximum allowed mtu value (1442 if host nic mtu is 1500). Another option would be to increase the host mtu all network devices outside the vm to be bigger by 58 than the vm mtu. The difference is caused by the
