Tweaks and tips for better performance with FreeBSD on KVM.
- Note: This has only been tested with FreeBSD 9.0-RELEASE (and patch levels).
Install FreeBSD
- Power on the VM.
- It should boot to the FreeBSD 9.0-amd64 DVD ISO.
- System Components: Add "src".
- Disks: Guided, use entire disk.
- Network: Use ipv4 only (unless you also use ipv6).
- Services: Add ntpd.
- This should leave you with FreeBSD 9 installed on the 32GB primary drive.
- Shut down the VM after installation.
- Remove the ISO from the VM's optical drive (set to empty).
- Verify the VM's boot order is set to the primary hard disk first.
First Boot
- Power on the VM and log in.
- Set the time:
ntpdate -s pool.ntp.org
- Update the system:
freebsd-update fetch freebsd-update install
- Reboot
Enable Virto
- Install virtio-kmod:
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/kernel
directory:
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/fstab
entries 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.conf
to:
ifconfig_vtnet0="DHCP"
- Shutdown the VM
shutdown -p now
- Change VM's network and disk hardware to use 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
