Hi, I came across this article recently:
http://www.cyberciti.biz/faq/linux-kvm-disable-virbr0-nat-interface/ and we are using NAT network for inter-VM communications. Now the box in question has it's own share of performance problems that we're struggling to resolve which means I'm not 100% sure our problems stem from above source. However I was wondering whether claimed performance degradation was *that* bad? If I do NFS-over-NAT for VM's - would that really kill performance or any other aspects of setup? Or to turn the problem on it's head - what would be the most effective (best performing) way of sharing [N]FS across VMs on the same box. In this particular case even dom0 is in the mix (i.e. it's a NFS-host serving data to all VMs over NAT'ed (actually - private) network). -- Dmitry Makovey Web Systems Administrator Athabasca University (780) 675-6245 --- Confidence is what you have before you understand the problem Woody Allen When in trouble when in doubt run in circles scream and shout http://www.wordwizard.com/phpbb3/viewtopic.php?f=16&t=19330 -- This communication is intended for the use of the recipient to whom it is addressed, and may contain confidential, personal, and or privileged information.
