This indeed looks strange if your notebook has 16 GiB of RAM. Could
you please try to capture also the initial output of NOVA, which should
look similar to

 NOVA Microhypervisor v7-84ce824 (x86_64): Nov 26 2015 17:54:18 [gcc 4.9.2]

 [ 0] CORE:0:0:0 6:f:b:0 [0] Intel(R) Core(TM)2 Duo CPU     T7700  @ 2.40GHz
 Hypervisor reports 1x1 CPU  - boot CPU is 0
 CPU has no invariant TSC.
 Hypervisor info page contains 11 memory descriptors:
 detected physical memory: 0x0000000000000000 - size: 0x9fc00
 use      physical memory: 0x0000000000000000 - size: 0x9f000
 detected physical memory: 0x0000000000100000 - size: 0x7ee0000
 use      physical memory: 0x0000000000100000 - size: 0x7ee0000

If your RAM is already missing from this output, we'd know where to
look for the cause of the issue.
