Re: [ovirt-users] PLEASE HELP - oVirt 4.0.5 Instability + Best way to rollback to 4.0.4
Hello oVirt Padawan, You can install new engine machine and import existing storage domains there. https://www.ovirt.org/develop/release-management/features/storage/importstoragedomain/ Please read restrictions and limitations. I think it's more safe way to go in such kind of situations.

Re: [Users] How do Networks and Vlan-tagging work in oVirt ?
Hello. Basically Ovirt operates with VLANs by creating tagged devices ethX.ID and attaching them to the bridge named network_name. For example: ovirt has ovirtmgmg, spice and 3 vm's networks: ovirtmgm (VLAN100), spice (VLAN101), vmnet1-3 (VLAN 201-203) Bridges for each networks will be created and attached: ovirtmgmteth0.100 spiceeth0.101 vmnet1 eth0.201 vnet1 -- VM will be attached here vmnet2 eth0.202 vnet2 -- VM will be attached here vmnet3 eth0.203 vnet3 -- VM will be attached here and so on. A VM is attached using the tun interface to the VM network You don't have to assign IP address to the bridge of any VM networks. IP addresses are required only for ovirtmgmt and display networks. -- Best regards, Pavel Zhukov mailto:pa...@zhukoff.net On Mon, 11 Feb 2013, Matt . wrote: I'm struggeling setting up my network in oVirt at the moment as I would like to seperate specific VM's from other devices/clients in my network.

Because I want to manage which client can acces which VM I need Vlan tagging. The question is where are we going to do this, on the VM itself or on the network I attach the VM's Nic to.
