HP Integrity Virtual Machines Release Notes Version A.03.50

The VM Host uses this space to start up guests, but guests are never swapped out. (A guest's
physical memory is locked down.) By turning off the swapmemon feature on the VM Host,
Integrity VM conserves RAM for guest use.
3.4 Do Not Create Golden Images of the VM Host for Guest Installation
Do not use the VM Host to create golden images to be used for guest OS installations using
Ignite-UX.
An Integrity system can be used to create a golden image suitable for OS installation on a virtual
machine, provided it has all of the VM Host software completely removed. To do so, remove
both the Integrity VM bundle (T2767AC) and the VMKernelSW bundle:
# swremove -x autoreboot=true T2767AC VMKernelSW
Before using the system to create a golden image, verify that neither of these bundles are installed.
That is, errors should result when querying the system with swlist:
# swlist T2767AC VMKernelSW
# Initializing...
# Contacting target "foo"...
ERROR: Software "T2767AC" was not found on host "foo:/".
ERROR: Software "VMKernelSW" was not found on host "foo:/".
For more information about using Ignite-UX golden images, see the Ignite-UX Administration
Guide.
3.5 Golden Images of Systems with HPVM-Guest Installed Must have HPVM
Device Drivers Configured
Golden images of systems with HPVM-Guest bundle installed must explicitly configure the
dynamic memory device driver. If your golden system has the HPVM-Guest bundle installed,
be sure the dynamic memory device driver is configured correctly in the associated golden
image's configuration file. To achieve this, add the line
set_kernel += “module hpvmdynmem loaded”
after the “init_sw_sel” stanza in the golden image's configuration file. Failure to do so might
render the dynamic memory control inoperable when the golden image is installed on a virtual
machine.
3.6 Numbers Reported by Glance 4.6 or above Running on VM Host
Might be Incorrect
Glance 4.6 or above running on a VM Host might report incorrect values (for example, vCPU
utilization is distorted and guest memory size is reported as being zero.). This is a warning, not
a performance problem.
3.7 Interleaved Memory on Cellular Hosts
HP recommends that you use only interleaved memory (ILM) on cellular hosts instead of using
cell local memory (CLM). When ILM is set too low on a CLM system, guests can fail to start.
Furthermore, a guest is not guaranteed to be placed on the same cell where its memory was
allocated, thereby, degrading performance. If your site requires CLM, contact HP Field Support
for possible alternatives.
3.8 hpvmcreate Manpage Incorrect
The hpvmcreate manpage incorrectly states that the default behavior for the -B start-attr
option is auto. This is incorrect. The default behavior is manual.
