we don't change anything else (except try to use smp in guest and update to 50). i don't know which version. i know kvm-46 with single cpu was working in a reasonable speed while kvm-50 is about 10 times (!) slower with 4 vcpu. -- Levente "Si vis pacem para bellum!" ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
