==Update Ports Tree==
 
Updating your ports tree will ensure that any ports you attempt to install will have the latest patches and download URLs.
 
 
* Update the ports tree using [http://www.freebsd.org/doc/handbook/updating-upgrading-portsnap.html portsnap]:
 
<pre>
 
portsnap fetch
 
portsnap extract
 
</pre>
 
* After the first run of portsnap, you can use the following command to perform later updates:
 
<pre>
 
portsnap fetch update
 
</pre>
 
 
==Enable Virtio==
 
* Install virtio-kmod:
 
<pre>
 
cd /usr/ports/emulators/virtio-kmod && make clean install
 
</pre>
 
* When prompted on each required package, accept defaults and OK.
 
* Add the following to <code>/boot/loader.conf</code>:
 
** '''Note:''' You may have to create this file.
 
<pre>
 
virtio_load="YES"
 
virtio_pci_load="YES"
 
virtio_blk_load="YES"
 
if_vtnet_load="YES"
 
virtio_balloon_load="YES"
 
</pre>
 
* Enable virtio for disk by changing your <code>/etc/fstab</code> entries to use the '''vtbd''' prefix. Example:
 
<pre>
 
# Device        Mountpoint      FStype  Options Dump    Pass#
 
/dev/vtbd0p2    /              ufs    rw      1      1
 
/dev/vtbd0p3    none            swap    sw      0      0
 
</pre>
 
* Enable virtio for network by changing the <code>ifconfig_em0="DHCP"</code> line in <code>/etc/rc.conf</code> to:
 
<pre>
 
ifconfig_vtnet0="DHCP"
 
</pre>
 
* Shutdown the VM
 
<pre>
 
shutdown -p now
 
</pre>
 
* Change VM's network and disk hardware to use virtio.
 
* Power on the VM.
 
* Verify that virtio is loading:
 
<pre>
 
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
 
</pre>
 
 
==Update Installed Ports==
 
It is a good idea to keep your installed ports up to date. This section shows you how to do so.
 
:'''IMPORTANT:''' It is recommended practice to understand how port updates will impact your system. Some port updates can change the way the program works and can break the function of your machine. '''It is wise to do a full backup of your VM before updating installed ports.'''
 
 
* Install [http://www.freebsd.org/cgi/url.cgi?ports/ports-mgmt/portmaster/pkg-descr portmaster]:
 
<pre>
 
cd /usr/ports/ports-mgmt/portmaster && make clean install
 
</pre>
 
* Run portmaster:
 
:'''Note:''' This step actually updates the installed ports on your system to their current versions. If you run into any errors, you will need to correct them and re-run portmaster to pick up where it left off.
 
<pre>
 
portmaster -a
 
</pre>

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
