Re: [ovirt-users] Issue with OVN/OVS and mandatory ovirtmgmt network

Hi All, I am also facing same issue (unable to change ovirtmgmt to OVS type). On git repository, I saw some commit in which added support to switch network type in host. but there is red cross across those changes. Would I get to know will this issue get solve in 4.1 release ? I tried modifying ifcfg-ovirtmgmt and ifcfg-eth0 file to support OVS and then rebooted m/c. When m/c got bootup I found that configuration made in ifcfg got overwritten by vdsm. Is their any workaround ?
