HPVM 2.0 is out of support since December 2008 - you need to upgrade to at least 3.5 (the last version that supports 11.23 as the VM host)

You can't assign the memory configuration you describe above as you aren't leaving any memory for the VM host (which runs HP-UX and needs some memory too!)

You want to go from:

VM Host: 32GB
VM Guest 1: 8GB
VM Guest 2: 8GB
VM Guest 3: 8GB
Total VM Mem 24GB

to

VM Host: 32GB
VM Guest 1: 16GB
VM Guest 2: 4GB
VM Guest 3: 12GB
Total VM Mem 32GB

That can't be done. The rule of thumb for VM host memory is 1.2GB + (8.5% of physical memory) which for your system is 1.2GB + 2.72 GB which is as near to 4GB as makes no difference. 32 - 4 = 28GB which is what you have to distribute amongst your VMs, so you'll have to compromise somewhere.

As far as the change goes - just shutdown all your VMs and then issue the hpvmmodify command to change memory allocation:

hpvmmodify -P -r

So to set a VM called myvm1 to have a total of 16GB of memory:

hpvmmodify -P myvm1 -r 16G

I would suggest to read chapter

2.3 Upgrading from Earlier Versions of Integrity VM

first, then ask if you have questions.

Record your configuration, backup the config and the host system before you start.

Hi Torsten/Duncan,

VM Host: 32GB
VM Guest 1: 8GB
VM Guest 2: 8GB
VM Guest 3: 8GB
Total VM Mem 24GB



1-can i shutdown VM Guest temporarily 1 and assign that 8GB also to VM Guest 3?.
2-If i re-assin the 8GB back to VM guest 1 after some testing on Vm guest 3 ,whether VM Guest 1 will work or not ,any booting issue will come ?

Dear Gurus,

pls reply on last thread.

Shutdown a guest and add or delete a certain amount of memory. If a guest doesn't have the minimum memory, it will just don't boot or panic during boot.
