Hi Folks:
Cobbler is an awesome tool! Thank you.
I would like to set up my VM's with their maximum memory different than
their set memory. This is because they may migrate to a hypervisor with
more RAM at some time in the future and I would like to avoid changing
them.
On the command line I would use commands like "xm mem-set ..." and "xm
mem-max ...".
In the cobbler GUI there only appears to be one setting for virtual
memory which sets both.
How can I set both max and set memory in cobbler/koan?
If that is not possible, can you suggest a way to do it before the VM
provisioned?
Perhaps something like this would work on hypervisor assuming the
vm-0103 was defined in cobbler with 4096MB of RAM?
Dom0# koan --virt --nogfx --system vm-0103
Dom0# xm mem-set vm-0103 2048 # use half the RAM for now
Dom0# virsh start vm-0103
Thanks,
Joe

It all sounds possible. However, it would take a change to cobbler to
add the new field (I would actually add the max mem field) and then to
koan to make use of it.

Hi Scott:
Thank you for considering it as a future modification. I am currently
working around it but I find that I have gotten so used to cobbler that
I want to put everything in it.
Regards,
Joe

Wouldn't this kind of change be better done in Puppet or CFengine?

No, I'd think it would be a provisioning thing, so something cobbler
probably should do. It also shouldn't be a hard change, someone should
put in a ticket for it.
