Well, virtualization lets you use an unknown OS without fear of compromising host security, so a real-time capable hypervisor (which kvm is, or very nearly) should be able to let you use an unknown OS without fear of compromising real-time response times. Right now the only unresolvable issue I see is wbinvd. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
