Bird on Ubuntu VM.

Hi, I currently have 2 servers Dell R310 with Bird 1.6 on Ubuntu (Active/Passive), one full BGP table and one IX, traffic around 400Mbps, simple BGP routing. I also have an HA cluster built on ESXi and I wonder if it would be a good idea to run BIRD (maybe 2.0/3.0?) on a VM (Ubuntu) on this ESXi HA cluster. What are your experiences with this, what are the limitations and recommendations? Kind Regards, Mike
