WARNING: This part is currently in test - it may render your system un-bootable when you make changes to your /etc/fstab.
This part is KVM specific, however, it is similar to installing VMWare Tools or Open VM Tools.
- Install virtio-kmod:
Enable Virto
cd /usr/ports/emulators/virtio-kmod && make clean install
- When prompted on each required package, accept defaults and OK.
- Copy the virtio modules into
/boot/kerneldirectory:
cp -Rp /usr/local/modules/* /boot/kernel/ kldxref /boot/kernel
- Add the following to
/boot/loader.conf:
virtio_load="YES" virtio_pci_load="YES" virtio_blk_load="YES" if_vtnet_load="YES" virtio_balloon_load="YES"
- Enable virtio for disk by changing your
/etc/fstabentries to use the vtbd prefix. Example:
# Device Mountpoint FStype Options Dump Pass# /dev/vtbd0p2 / ufs rw 1 1 /dev/vtbd0p3 none swap sw 0 0
- Enable virtio for network by changing the
ifconfig_em0="DHCP"line in/etc/rc.confto:
ifconfig_vtnet0="DHCP"
- Shutdown the VM
shutdown -p now
- Change network and disk drivers to virtio.
- Power on the VM.
- Verify that virtio is loading:
kldstat Id Refs Address Size Name 1 12 0xffffffff80200000 11cdab0 kernel 2 5 0xffffffff813ce000 4ca0 virtio.ko 3 1 0xffffffff813d3000 5880 virtio_pci.ko 4 1 0xffffffff813d9000 5010 virtio_blk.ko 5 1 0xffffffff813df000 aeb0 if_vtnet.ko 6 1 0xffffffff813ea000 3210 virtio_balloon.ko
