==Pre-Install==
==Enable Virto==
* Find the downloadable ([https://download.freebsd.org/releases/amd64/amd64/ISO-IMAGES/13.1/ amd64 dvd1.iso version]).
* Install virtio-kmod:
* 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
 
==Create VM==
* Use "Create VM" in GUI
* In "Create: Virtual Machine" use these settings
** "General" - default settings
** "OS"
*** Set "ISO Image" to your downloaded ISO file
** "System" - default settings
** "Disks"
*** Set "Disk Size" to 8GB (or higher)
** "CPU"
*** dual-socket and/or dual-core
** "Memory" - 2GB (minimum)
** "Network" - Virtio
 
==Install FreeBSD==
* Start the VM.
* Boot menu with countdown will show - just wait and it should boot to the optical drive by default and start the installation
* ([https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-start Installation guide])
* ([https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-components System Components])
** 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.
* Change any other configurations offered. When you get to "Final Configuration" you can select Exit
* This should leave you with FreeBSD 13.1 RELEASE installed on the primary drive
* Reboot
* 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
 
==First Boot==
* Power on the VM and log in.
* Set the time:
<pre>
<pre>
cd /usr/ports/emulators/virtio-kmod && make clean install
ntpdate -s pool.ntp.org
</pre>
</pre>
* When prompted on each required package, accept defaults and OK.
* Update the system:
* Copy the virtio modules into <code>/boot/kernel</code> directory:
<pre>
<pre>
cp -Rp /usr/local/modules/* /boot/kernel/
freebsd-update fetch
kldxref /boot/kernel
freebsd-update install
</pre>
</pre>
* Add the following to <code>/boot/loader.conf</code>:
* Reboot
<pre>
<pre>
virtio_load="YES"
reboot
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 network and disk drivers to 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>
