Re: [Users] Networking questions (LONG)

Hello Lior, Thank you for your reply. Quoting "Lior Vernia" <lvernia(a)redhat.com&gt;: That would be doable, except I am not sure if there is a limit to the number of vNICs a VM could have and/or if there is an OS-level limit to how many? It is also a bit "messier" IMO, but that is more of a personal issue than a technical one, and one I could probably get over :-) When you say that oVirt currently doesn't allow creating VLANs inside VMs, are you referring to the use of VLAN interfaces like I describe (e.g., "eth1.1", "eth1.2", "eth1.10", etc.)? If so, is that an oVirt limitation, or a KVM one? I have seen examples where one can create a "Trunk" with KVM and Open vSwitch, and I thought for some reason oVirt used Open vSwitch, but none of the commands I tried from the examples were found. A check of <http://www.ovirt.org/Features/Node/OpenVSwitchSupport> shows that indeed there does not appear to be any integration yet, and it is only 60% done :-( With regards to using the dummy interfaces, I realised I probably do not need to add them to a bridge, since they would be physical NICs in production (this is just for testing). I initially did create the "ovirtvm" bridge before I realised that, but have made them "stand-alone" NICs with no IPs attached to them, but they are not "green" in oVirt when I try to attach my logical networks to them under "Networks > Hosts > vmhost01 > Setup Host Networks". When I am in "Setup Host Networks", I see my dummy interfaces, but they have a red dot instead of a green one (like what "eth0" has). I can my logical networks to them, but the "Network Device Status" has a red arrow pointing down. Here are my ifcfg-dummy* files: --- ifcfg-dummy0 --- DEVICE=dummy0 ONBOOT=yes TYPE=Ethernet DELAY=0 BOOTPROTO=none NM_CONTROLLED=no STP=no --- ifcfg-dummy0 --- My "ifcfg-dummy1" is identical, except of course it has "DEVICE=dummy1" in it. The interfaces do come up on the host, but as I said, in "Setup Host Networks" they have a red dot instead of a green one. Perhaps I do need to assign an IP? I can maybe assign a "dummy" one (i.e., one that I would never use)? -Alan
