I think the documentation should cover the worst case scenario, and direct users to do the safest thing to ensure things go smoothly, even if it means some down time. Feel free to open up an account on the wiki and start contributing. :-)

What type of RAID card are you using?

Nothing has changed since 2.x. Follow those directions and you will be good to go. I went ahead and updated the wiki to reflect that, along with another frequently asked question.

It looks like the preferred solution is to configure and use shorewall to do it. You'll want to set up 3 different zones, and define how traffic can move between the three. In my case, I want to install a web filter/firewall as a VM, so I will have to figure out how to tell shorewall to send...

Did anything ever come of this? Did you figure out the cause?

I haven't seen any problems yet with windows server 2012 vms, but my systems are all very low load right now, so I'm not a valid test case. I'm assuming you have some other imaging solution to run on the vms so you aren't totally exposed to failure?

To do what you want, I would use a APC switched power outlet as the fencing device. That will kill power to one of your nodes and reboot it. I think they call it STONITH - shoot the other node in the head. For windows clusters, we used a small quorum drive. Whoever had control of that had all...

Like I said in the other thread - Fencing. It's in the wiki.

I think it is possible to do it that way. If you use HA, all of your vms would run on only one of the nodes at a time. You would need to set up fencing to enforce that.

Well, I have figured out how to expose my ancient topspin HCA via pci pass through. It shows up in windows 2012, but I have not found any drivers yet. I doubt I will be able to share a card among multiple VMs.

Hi, Have you had any additional success, e100? Many thanks for your IB writeup in the wiki! Has anyone been able to turn a ib interface into a bridge that can be used by proxmox vms? I've tried, but have so far been unsuccessful.
