hi, at my workplace we have several freebsd 8.2 and 9.0 kvm vm's in production (ldap, dns and webmail server). we use virtio drivers and network performance is very good. there was one problem for us with kvm & virtio as i already wrote at freebsd mailing list. suddenly /var/log/message at kvm hosts start to growing at very high rate with warnings about some vlan problems. solution was to use -tso option with ifconfig_vtnetX in rc.conf. anyway, that's only problem for us with kvm and freebsd. anyway, linux is still better option if you need performance (block and io) then freebsd in both cases, vmware and kvm. we also tried openbsd in vmware and kvm. and that's bad. unfortunately. ps. yesterday i tried to do freebsd-update -r 9.1-RELEASE upgrade at one of my production kvm vm. everything went ok but immediately after reboot i've got kernel panic. something about unsupported cpu. i didn't have time to investigate where's the problem.
