Hi,

Below is /proc/cpuinfo on one of the VM. I believe that they are all the
same, but I'm not 100% sure.

I don't have any information about the kernel/hypervisor used on the
host system. In the VM, it's the current stretch kernel:
# uname -a
Linux ip-172-31-3-87 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 
GNU/Linux
