[ovirt-users] oVirt 3.5.3 Host Network Interfaces

[Prof. Dr. Michael Schefczyk]

Dear All,

Having set up a Centos 7 server with Gluster, oVirt 3.5.3 and hosted engine according to https://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/, I was hoping that the NIC management and particularly NIC bond/bridge capabilities would have improved a bit. My server has four NICs, two connected to the LAN and two to an adjacent server to be used as a Gluster network between the two servers. My aim is to use NIC bonding for two NICs each.

Via the engine, I would like to use Hosts -> Network Interfaces -> Setup Host Networks. As I use hosted engine, I cannot set the only host to maintenance mode. At least during normal operations, however, I am neither able to change the ovirt bridge from DHCP to static IP nor create a bond consisting of the two LAN facing NICs. In each case I get, "Error while executing action Setup Networks: Network is currently being used". Editing the network scripts manually is not an option either, as that does not survive a reboot. Contrary to this real view, everything should be easily configurable according to section 6.6 of the oVirt administration guide.

One workaround approach could be to temporarily move one NIC connection from the adjacent server to the LAN or even temporarily swap both pairs of NICs and edit interfaces while they are not in use. Is this really the way forward? Should there not be a more elegant approach not requiring physically plugging NIC connections just to work around such issue?

Regards,

Michael
