Re allocate memory on virtual machine

kggj — Mon, 21 Jan 2008 20:41:08 GMT

Hi

We have an HP integrity virtual machine ( 3 guest machines on the physical server).

We want assign 10 GB memory from one of the virtual machine to another virtual machine on the same physical host.

How do I re allocate memory from one virtual machine to the other one ?

Read the man pages for hpvmmodify.

hpvmmodify -P vguest1 -r (x)G

hpvmmodify -P vguest2 -r (x)G

You will need to reboot both VGuests for the changes to take effect.

With newer versions of IVM memory allocation is suppose to be on the fly. Not sure what real life dictates.

From the version 3 release notes:

"Administrators can dynamically change the size of memory allocated to the HP-UX guest"

What version do you run?
