HP Integrity Virtual Machines Installation, Configuration, and Administration

Setting ram_dyn_type to any or driver enables the other dynamic memory configuration
controls. The minimum (ram_dyn_min) and maximum (ram_dyn_max) values bound the value
of ram_dyn_target_start. The value of ram_dyn_target_start is set to 2 GB.
9.6.1.1 Viewing Dynamic Memory on the VM Host
On the VM Host, dynamic memory software is included with Integrity VM. Dynamic memory
parameters and status are displayed for each guest using the standard Integrity VM commands.
For example, for the guest named compass1, the hpvmstatus command displays the following
dynamic memory information:
# hpvmstatus -V -P compass1
