> 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.
