Hi, we're running RedHat Enterprise Linux 7 (64bit) on ESXi 5.5. The VM has 2 GB RAM allocated. However, in the guest OS, Output of "free" or /proc/meminfo show that total memory is a bit less than 2GB (18xxxxx bytes). I've no idea as in VMware KB: Virtual machine memory limits and hardware versions , guest with hardware version of 7 or above can 'see' all the memory allocated.
Would anyone please help? Thanks a lot.
