Hello. I realize that at least 3 nodes are needed for a VM HA cluster. My question is whether 3 compute nodes + at least 1 management/control node are required in an HA setup, or is it possible for management and compute to be co-hosted on the same node/s?
 
PVE doesn't have a split between management and compute nodes - every node is automatically both.
 
I would recommend reading our Admin Guide, chapters 5, 6 and especially 12 ;)
 
Footnote on this thread, for what it is worth. "3 nodes" can mean, 2 x beefy nodes that actually do stuff, and 1 x node which does not really do anything much other than 'be alive and act as the tie-breaker'. So 2 x boxes with 512gigs ram and 64 cores each. Then one box single-core and 2gb ram. Bouf, a '3 node cluster'. :-)
