Hi folks,
Problem: My kvm server (8 cores, 64 GByte RAM, amd64) can eat up
all block device or file system performance, so that the kvm clients
become almost unresponsive. This is _very_ bad. I would like to make
sure that the kvm clients do not affect each other, and that all
(including the server itself) get a fair part of computing power and
memory space.
What config options would you suggest to build and run a Linux
kernel optimized for running kvm clients?
Sorry for asking, but AFAICS some general guidelines for kvm are
missing here. Of course I saw a lot of options in Documentation/\
kernel-parameters.txt, but unfortunately I am not a kernel hacker.
Any helpful comment would be highly appreciated.
Regards
Harri
