multiple subnets on hosts for vm's
This is not critical but some functionality I think should be in Ovirt and maybe I am going about it the wrong way. I have several subnets on my physical network. My engine host is separate from the clustered hosts that house the vm's. In order for the vm's on the other subnets (vlans) to get Internet access, I have to add the extra ip addrs on the ovirtmgmt network interface. I have read and tried every solution I could find trying to add teh subnets without using the extra ip addrs option but the machine either becomes isolated or will not start at all. Can someone tell me how to add the vlans so the engine host sees and utilizes them? The engine host can get to resources on the vlans because of the router config but will not let any subnet except ovirtmgmt outside the cluster. This is not critical but something I would like to get working for future deployments. Thank you for your help. Eric
I'd basically like to second the "request" or question: I started on an /28 allocation, because that was the only available at the time. In the mean-time I managed to get hold of a full class C net, which I'd like to use for the VMs on a 3-node HCI with a couple of extra compute and gluster storage nodes added in the course of its life, without having to rebuild from scratch. I'd be happy to just add the extra range on the hosts in parallel or I'd do a move, but somehow I'm afraid that IPs or/or DNS names are baked into configuration files if now downright database tables, to make such a thing easy or possible. I tried just adding the extra subnet on /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt and that works for a while, but it seems that VDSM is regularly overwriting that from data stored in /var/lib/vdsm/persistence/netconf/nets and that syntax there may not support the sort of syntax that the ifcfg scripts have for additional IP subnets (PREFIX instead of NETMASK, IPADDR[n]) etc. I can't really go into VLANs, because servers in that environment are access mode exclusively.
