[one-users] How-to set RAM on Running KVM VM in CentOS 6.2x86 + openNebula v3.6

[Jurgen Weber]

I am having the same problem/trying to work out how to do this.. I would 
like to increase some VM's from 2 cores to 4.

using 3.4, and sunstone I do not see a re instantiating button.

You could resubmit it, but doesn't that blow away your disk and start 
again from scratch? I do not want that.

Thanks
