Proxmox 3 on AMD E450: pfSense 2.1, NAS4Free, PiaF, Debian

yes, this is a bug in kvm kernel code and amd processor. (this should be fixed soon in 3.10 host kernel)

all virtual processor with amd64 vendor (so kvm64,opteron_gX or host) will not work with physical amd processor currently.

I see... the issue is isolated to pfSense though. kvm64 vCPU works fine for Linux VMs.
