Hello,
I know the parameter mem-max sets the maximum RAM that can be
allocated
to a domU.
Beside this limit, VM has to be recreated with required memory
size.
Is it possible to set the mem-max parameter without recreating
VM?
xm max-mem seems to work but in fact, has no effect (at least on
my
debian Lenny dom0)
If not possible to dynamicly change max-mem, Is it
possible/safe/clever
to set max-mem to the maximum amount of RAM the dom0 can
allocate (total
RAM - minimum dom0 RAM).
Thanks.
If you are going to be using these DomUs for anything even
remotely serious, then I would strongly advise against dynamically
resizing a Linux environment's available memory. Form personal
experience, I can categorically say that this leads to a very
unstable system.
Just my 2 pence
Even without keeping beside the memory-max? I remember Having done
it too but it did not turn the system unstable AFAICT.
Does anybody have similar feelings about playing with meme making
Linux domU unstable?
regards
Thanks
