Is there a way to see if several Virtual Machines are running on the same host? Specifically, I have three VMWare VMs (each running a Ubuntu Server 14.04) and I have tried to compare different pieces of information:
dmidecode -s system-serial-numbergives different results for each VM
lspcireturns the same output for each VM
cat /proc/cpuinforeturns similar values for two of them and one has a completely different output (notably the "model name" line is different)
This doesn't help me to find determine which ones are running on the same host (if any).
Are there any other way to check?
