CentOS is a bit bitchy about booting from harddisk. You'll have to provide a shorter "linux"-grub-line than what's written in the "grub.conf"-file; some- thing like this: linux /vmlinuz-2.6.32-431.el6.x86_64 ro root=/dev/mapper/VolGroup-lv_root initrd /initramfs-2.6.32-431.el6.x86_64.img or else the LVM-groups won't get activated. >> Ping times to the VM are fluctuating - ranging from 0.185ms to 35ms. > > Hmmm, will look at that as well. For what it's worth, this is my "bhyve"-command line: =============================================================================== bhyve \ -w \ -c 3 \ -m 4096M \ -A \ -H \ -P \ -l com1,/dev/nmdm0A \ -s 0,hostbridge \ -s 1,lpc \ -s 2,ahci-cd,/mnt/iso/${ISO} \ -s 3,virtio-blk,lun0 \ -s 4,virtio-blk,lun1 \ -s 5,virtio-net,tap0 \ ${VM} =============================================================================== My host CPU is an "AMD Phenom(tm) II X6 1055T Processor"...
