I can provide some info about what we're running the juju controllers on where we see this.
The controllers are in KVMs with 24G memory, and 4 cores and 50G disk. The machines hosting the KVMs (3 per machine) are also running 3 vault KVMs (4G memory, 2 cores, 40G disk)
the hosts have 2 240g ssd's, 64G memory, and 4 core processor (3.4GHz). We over commit memory by 2x and cpu by 5x. I dont feel like we're pushing the machine to its limits with the over commit.
