we could consider a special OS type of SystemVM and create the correct/best
mappings for each hypervisor and version thereof in the guestos table.

>
> An edge case, systemvms use the guest os type 15 (or Debian 32-bit) which may
> lead VMware vCenter to not allocate all the RAM (default 256MB) to the guest.
> Via vCenter it shows that 256MB is allocated, but free -m (or cat
> /proc/meminfo) revealed that only 157MB was allocate in my testing against
> VMware 5.5 and 6.5. The fix would be to use a more appropriate guest os type
> that works for VMware 5.0+, other 64-bit Linux. We cannot use Debian7+ 64-bit
> as the guest os type is not available on older vCenter.
