Thanks, that'd be great. Some suggestions: if you're not already, I'd recommend using ahci-hd for disk images instead of virtio-blk. The AHCI emulation uses a thread for block i/o so won't block the VM on reads. Also, I'd recommend using a network login to the guest rather than running something from the console. The UART emulation in bhyve will result in a lot of VM exits, which can impact performance. later, Peter.
