HPVM problems with dynamic memory

likid0 — Thu, 07 Aug 2008 11:13:30 GMT

Hy,

I am triying to use dynamic memory with my guests
but the memory driver doesnt look like its loading on the guests.
Version A.03.50.00

with hpvmstatus I don't get all the info:
[Dynamic Memory Information]
NOTE: Dynamic data unavailable, configured values only
Type : driver
Minimum memory : 512 MB
Target memory : 5120 MB
Maximum memory : 5120 MB

And when I try to reduce memory I get:

/root# hpvmmodify -P vmf -x ram_target=4122
hpvmmodify: ERROR (vmf): Query to dynamic memory driver failed: Function is not available.
hpvmmodify: Failed to set ram_target.
hpvmmodify: Unable to modify the guest.

I have tried using any and driver with the same result.

-x ram_dyn_type={any|driver}

Any idea what module, daemon has to be loaded on the client get this working ?

Hello,

What does this command show:

# hpvmmgmt -V -l ram

Did you run command on VM Host to start it
and enable dynamic memory capability:

# hpvmmgmt -x ram_target=start
# hpvmmodify -P guestXYZ -x ram_dyn_type=any

Cheers,

From the manual:

hpvmmgmt: Manages the guest memory allocation. Runs on guests only.

Did you install the hpvm_guest_depot on the guest?

It's in

/opt/hpvm/guest-images/hpux/11iv2 or 11iv3/hpvm_guest_depot.11iv_x_.sd

on the host and needs to be installed on the guest.

Once installed on the guest the tool will be in

/opt/hpvm/bin

Did you really enable dynamic memory? This is not enabled by default.

See chapter

9.6.1.1 Configuring a Virtual Machine to Use Dynamic Memory

Please provide

# hpvmstatus -V -P

On the host i did configure the dyn mem with driver:

[Dynamic Memory Information]
NOTE: Dynamic data unavailable, configured values only
Type : driver
Minimum memory : 512 MB
Target memory : 5120 MB
Maximum memory : 5120 MB

On the guest side, I tried loading the module:

vmf:/opt/hpvm/bin# kcmodule hpvmdynmem=loaded
* The automatic 'backup' configuration has been updated.
NOTE: No change to 'hpvmdynmem' was needed.
Module State Cause Notes
hpvmdynmem loaded explicit auto-loadable, unloadable
vmf:/opt/hpvm/bin# ./hpvmmgmt -V -l ram
Dynamic memory driver not found on guest.
hpvmmgmt: Unable to continue.

and checked that the filesets are configured:

# vmGuestLib
vmGuestLib.GUEST-LIB configured
# vmProvider
vmProvider.VM-PROV-CORE configured
# vmTools
vmTools.VMTOOLS-MAN configured
vmTools.VMTOOLS-RUN configured

The hole hpvmstatus output:

hpvmstatus -V -P vmf

The chapter

9.6.3.6 Enable Dynamic Memory on the Guest and on the VM Host

says:

For example, if the guest management software is
not installed, the hpvmstatus command displays the following:
# hpvmstatus -V -P compass1
.
.
.
[Dynamic Memory Information]
NOTE: Dynamic data unavailable, configured values only
Type : driver
Minimum memory : 1024 MB
Target memory : 2048 MB
Maximum memory

...

This is what you have.

The manual refers to:

Complete instructions for installing the guest management software are in the README.txt file
in /opt/hpvm/guest-images/hpux directory

I don't have access to this file, but maybe the solution is within.
