Virtual Machines¶. A Virtual Machine (VM) is an environment on a host computer that can be used as if it were a separate physical computer.VMs can be used to run multiple operating systems simultaneously on a single computer. Operating systems running inside a VM see emulated virtual hardware rather than the actual hardware of the host computer. A reader recently commented on my post about upgrading to FreeNAS version 8 and asked if I had any advice for installing FreeNAS on VirtualBox. The thought of virtualizing FreeNAS didn’t occur to me but it’s actually a great idea so I decided to give it a try. Recently we have been working on a new Proxmox VE cluster based on Ceph to host STH. During the process we have been learning quite a bit experimenting with the system. While the VMware ESXi all-in-one using either FreeNAS or OmniOS + Napp-it has been extremely popular, KVM and containers are where.
If you would like to use an already created VM as your template do the following:

- Copy and rename the folder from which your template was based on
- Stop the running VM and use dd on the FreeBSD CLI
- Then rename the image and compress it, this may take a while.
- This last little rename/compress step was just to conform with the same naming conventions as my source template, at which point I then edited the
template.json
file in the directory created previously to correctly reference this new image and edited some of the book-keeping fields to match, then I uploaded the os.img.gz file to the location specified in theurl
field (which could be any HTTP server you have access to) and filled in thesha256
checksum field by runningshasum -a 256 os.img.gz
and pasting in the results. - Finally, commit the result to github with a git commit / git push, then add your github vm-templates repository under VM -> Settings in the form of https://github.com/[username]/vm-templates and voila! Your new template will now show up along with all the other templates.
Manually create a new OS template from an existing template
Here's the step-by-step process I used to create the FreeBSD-current (11.0)template, using freebsd-current as thestarting image. I also used bhyve running on FreeBSD 10.3 as the bootstraphost, though some folks have reported good results with xhyve on the Mac.
- First, obviously, I needed to check out the vm-templates repo and start working in it:
- Next, you have to acquire the template disk image, I copied the template that looked the most like my target template. In my case, since I was targetting another FreeBSD template, it was obvious enough to simply duplicate the existing FreeBSD 10.2-zfs template (a 10.2 install with the ZFS option selected).
- Then I grabbed an ISO installation image from ftp.freebsd.org, as linked above, and started the steps to get bhyve ready to boot it:

- Then I ran bhyve's helpful vmrun.sh script to start things off.
- At this point, FreeBSD's standard installer ran, the appropriate ZFS installation options were chosen, and I exited bhyve by selecting the loader prompt on the next reboot and typing 'quit'. This dropped me back to the shell on the host OS, where I was next able to do:
This last little rename/compress step was just to conform with the same naming conventions as my source template, at which point I then edited the
template.json
file in my new freebsd-11-zfs direcory to correctly reference this new image and edited some of the book-keeping fields to match, then I uploaded the os.img.gz file to the location specified in the url
field (which could be any HTTP server you have access to) and filled in the sha256
checksum field by running shasum -a 256 os.img.gz
and pasting in the results.- Finally, I committed the result to github with a git commit / git push, added my github vm-templates repository under VM -> Settings in the form of https://github.com/[username]/vm-templates and voila! My FreeNAS 10 CLI now shows:
Freenas Vm Host 2017
Demonstrating that the template list is automatically pulled from github.

- Of course, the final proof was to actually create a VM with the new template on my FreeNAS 10 box:
