Re: [Xen-users] Re : ha cluster with virtual machines as resources
As far as i have played with Xen , You can dynamically allocate RAM to
a running VM but the OS inside the VM is NOT able to detect the
increased RAM and therefore cannot utilize it.
If you reboot the VM , then on reboot it will show the increased memory.
( Conditions like max mem are assumend to be satified)
If I'm not completely off here, Linux PVM domUs *do* see and utilize it.
Adding memory is not a big problem, reducing the amount of memory is
one. Just imagine a process using 500 megs and you take away 200 of that
while it is running. If you have 200 megs of unused memory, this should
work, though.
