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-number
gives different results for each VMlspci
returns the same output for each VMcat /proc/cpuinfo
returns 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?
