HP Integrity Virtual Machines Installation, Configuration, and Administration

9.6.3.6 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 guest0
.
.
.
[Dynamic Memory Information]
NOTE: Dynamic data unavailable, configured values only
Type : driver
Minimum memory : 1024 MB
Target memory : 2048 MB
Maximum memory : 3072 MB
.
.
.
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 guest0
hpvmmodify: ERROR (guest0): 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.
hpvmmgmt: Unable to continue.
# hpvmmgmt -x ram_target=2048
Failed to open dynamic memory driver, error: No such device.
Failed to set dynamic value error: No such device
hpvmmgmt: Unable to continue.
For information about enabling dynamic memory, see Section 9.6.3.6: “Enable Dynamic Memory
on the Guest and on the VM Host” (page 127).
9.6.3.7 Upgrade the Guest Kit When Upgrading Integrity VM
The dynamic memory software has two components: the VM Host support and the HP-UX guest
support. These two components must be at the same version level for dynamic memory to
function. When you upgrade Integrity VM, you must also install the new guest kit on the guest.
During this upgrade process, dynamic memory may not function.
If there is a version mismatch, a message is written to the VM Host's syslog when the guest
starts. For example:
Mar 6 14:47:37 host vmunix: (hpvmdvr) Dynamic memory version mismatch Guest 5.
Please update the guest kit
This example indicates that the guest management software kit on virtual machine number 5 is
out of date. To determine which guest is number 5, use the hpvmstatus command. In the
following example, guest 5 is named dale:
# hpvmstatus
Virtual Machine Name VM # OS Type State #VCPUs #Devs #Nets Memory Runsysid
==================== ===== ======= ========= ====== ===== ===== ======= ========
chip 1 HPUX On (OS) 2 1 1 3 GB 0
dale 5 HPUX On (OS) 2 1 1 3 GB 0
For information about installing the HP-UX guest management software, see Section 4.2:
“Installing HP-UX Guest Management Software” (page 47).
