An indication of this problem is a small or zero amount of free memory and a large memory
pressure value (100). If these indicators are present, use the hpvmmodify command on the VM
Host to increase the memory size of the guest. The guest then boots normally.
9.7.3.5 Actual Memory Allocations Might Differ
If you specify a value for the ram_target or ram_dyn_target_start parameter that results
in a change in memory size that is not a multiple of 64 MB, the target value is reset.
For example, if you specify 6 GB of memory, the HP-UX guest actually has access to 6135 MB of
memory. If you attempt to set the memory size to 2048 MB, the amount of memory actually
removed is 4087 MB. This is not a multiple of 64 MB, so the target memory size is reset to 2103
MB.
9.7.3.6 Enable Dynamic Memory on the Guest and on the VM Host
The guest management software must be installed on the guest before you can use dynamic
memory parameters on the VM Host system. For example, if the guest management software is
not installed, the hpvmstatus command displays the following:
# hpvmstatus -V -P host1

If you attempt to modify the guest's dynamic memory from the VM Host, the following errors
are displayed:
# hpvmmodify -x ram_target=2048M -P host1
hpvmmodify: ERROR (host1): Query to dynamic memory driver failed: Function is not available.
hpvmmodify: Failed to set ram_target.
hpvmmodify: Unable to modify the guest.
If you attempt to modify the dynamic memory from the guest, the following errors occur:
# hpvmmgmt -V -l ram
Dynamic memory driver not found on guest.
