Hello,

we have an Dell Server with an DRAC installed, now we have the Problem, that when we run an virtual Machine on the Hostnode we can't Ping the DRAC from the Hostnode or every VM who is running of them. I found this Thread at the ESXi Forum: https://communities.vmware.com/message/1324399#1324399

Now my Question, Proxmox has Open vSwitch Support - how we have to configure our Network for the Solution who's postet in the ESXi Forum? I'm absolutly not an Pro with Open vSwitch, so i hope here is a crack who has the knowledge and want to share it with me :)

Thanks!

Kind Regards

Open vSwitch has to be installed from Proxmox repository (if used in Proxmox hosts, the standard Wheezy package does not work well in Proxmox!)
Code: 
deb http://download.proxmox.com/debian wheezy pve-no-subscription

You have to use version 2.0.90-... verify if available by

Code: 
aptitude versions openvswitch-switch

Install then by

Code: 
aptitude install openvswitch-switch

Now you have a virtual switch with features like a managed switch, you can define virtual ports as well as using the physical NICs as port.

http://forum.proxmox.com/threads/18331-Migrating-to-Open-vSwitch?p=93851#20 shows a global example containing some typical configuration cases.

If you want to get detailed advices for your case please post the details about your network as it should be configured (the best would be a small diagram what do you want to have where etc., especially where your Proxmox host(s) is (are) located - referencing to a similar and not precise described case as above can lead to misunderstanding).

Kind regards

Hi,

your problem is not related to openvswitch.

This is not magic, you hostnode need to be able to reach from the network the drac or the vms ips.
So, on the same network subnet or routed through the gateway.

can you describe your network subnet/ ips (host,drac,vms)
 
Hi,

i talked to Dell, they say, the iDRAC Traffic are in her own Network in LOM1 and LOM2, so the Switch don't unterstand what they have to do - and so, the Hostnode can't Ping his own iDRAC. There are 2 Networks per LOM, the Hostnode and the iDRAC.

I don't say its an Open vSwitch problem, the iDRAC are not designed for HA - but i want to Share the iDRAC over LOM1 and LOM2 and not over the dedicated Port. So the only way is, to configure it like in the Thread in the ESXi Forum - but i don't know what i have to create.

Current the iDRAC and Server are in the same Network, local -> DHCP (192.168.2.104 Node and 192.168.2.111 iDRAC - Mask 255.255.255.0 Gateway 192.168.2.1). If i can Ping the iDRAC with the Hostnode, so there are no Problem with the VM's.
