Setting up a FreeBSD Guest on PVE.
:'''Note:''' This has been tested with FreeBSD 13.1 RELEASE.
 
==Pre-Install==
* Find the downloadable ([https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.1/ amd64 dvd1.iso version]).
* Mimimum hardware ([https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-hardware requirements])
** 2-4GB RAM
** 8 GB drive space
*** Full install without jails will use at least 5GB
*** If you will be using jails and building kernel from source, use at least 35GB
 
==Create Install Media==
* Option 1: (IDEAL) Using Proxmox GUI, local Storage > Download from URL, copy in ([https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.1/ ISO link]), query it to get file name, and use the contents of the provided ([https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.1/ CHECKSUM file]) to verify the download
* Option 2: Using Proxmox GUI, local Storage > Upload file from your non-Proxmox machine
* Option 3: (for server without internet) Download ISO image and burn to DVD or save to USB drive then transfer to server


:'''Note:''' This has been tested with FreeBSD 9.0-RELEASE and 9.1-RELEASE (and patch levels). Some steps have been removed as they have been deprecated in newer FreeBSD versions.
==Create VM==
==Create VM==
* Download the FreeBSD 9.1-RELEASE-amd64 DVD ISO (from [http://www.freebsd.org/where.html here]) and transfer it to your VM server.
* Use "Create VM" in GUI
* Create a new VM:
* In "Create: Virtual Machine" use these settings
** CPU: dual-socket or dual-core
** "General" - default settings
*** '''IMPORTANT:''' As of current PVE releases, you may need to set your CPU to '''qemu64''' rather than '''kvm64''' for FreeBSD to be able to boot.
** "OS"
** RAM: 2GB (minimum)
*** Set "ISO Image" to your downloaded ISO file
** Network: Intel e1000 (bridged)
** "System" - default settings
** Create a 32GB primary disk (scsi, qcow2)
** "Disks"
** Add FreeBSD 9.0-amd64 DVD ISO as an optical drive (scsi).
*** Set "Disk Size" to 8GB (or higher)
** "CPU"
*** dual-socket and/or dual-core
** "Memory" - 2GB (minimum)
** "Network" - Virtio


==Install FreeBSD==
==Install FreeBSD==
* Power on the VM.
* Start the VM.
* It should boot to the FreeBSD 9.0-amd64 DVD ISO.
* Boot menu with countdown will show - just wait and it should boot to the optical drive by default and start the installation
* System Components: Add "src".
* ([https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-start Installation guide])
* Disks: Guided, use entire disk.
* ([https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-components System Components])
* Network: Use ipv4 only (unless you also use ipv6).
** If you will be installing jail templates, make sure to check "System source tree"
* Network
** Choose vtnet0 VirtIO Networking Adapter
** Use ipv4 ONLY, unless you also use ipv6
* Disks
** Auto (ZFS) Guided Root-on-ZFS, stripe virtual device, choose vtbd0 VirtIO Block Device
** If you are planning to also transfer the image to another cloud host as a standalone OS, make sure they support ZFS, or change your selections accordingly
* Services: Add ntpd.
* Services: Add ntpd.
* This should leave you with FreeBSD 9 installed on the 32GB primary drive.
* Change any other configurations offered. When you get to "Final Configuration" you can select Exit
* Shut down the VM after installation.
* This should leave you with FreeBSD 13.1 RELEASE installed on the primary drive
* Remove the ISO from the VM's optical drive (set to empty).
* Reboot
* Verify the VM's boot order is set to the primary hard disk first.
* After reboot, check:
** In VM > Hardware remove the ISO from the VM's optical drive (set to empty)
** Verify in VM > Options the boot order is set to the primary hard disk first

==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>
<pre>
cd /usr/ports/ports-mgmt/portmaster && make clean install
reboot
</pre>
</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>
==External Links==
