ifconfig_vtnet0="DHCP"

* Shutdown the VM
<pre>
shutdown -p now

Setting up a FreeBSD Guest on PVE.

Note: This has been tested with FreeBSD 10.3 RELEASE (and patch levels). Some steps have been removed as they have been deprecated in newer FreeBSD versions.

Create VM

  • Download the FreeBSD 10.3-RELEASE-amd64 DVD ISO (from here) and transfer it to your VM server.
  • Create a new VM:
    • CPU: dual-socket and/or dual-core
    • RAM: 2GB (minimum)
    • Network: Virtio
    • Disk: 32GB (or higher), virtio, qcow2
    • Add FreeBSD 10.3-RELEASE-amd64 DVD ISO as an optical drive.

Install FreeBSD

  • Power on the VM.
  • It should boot to the FreeBSD 10.3-RELEASE-amd64 DVD ISO.
  • System Components: Disable optional (games, etc).
  • Disks: Auto (ZFS) Guided Root-on-ZFS, stripe virtual device, choose vtbd0 VirtIO Block Device.
  • Network: Choose vtnet0 VirtIO Networking Adapter. Use ipv4 only (unless you also use ipv6).
  • Services: Add ntpd.
  • This should leave you with FreeBSD 10.3-RELEASE installed on the 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
