Today I managed to get the to fun part of proof of concepting a migration from #Nutanix/AHV to #Proxmox.

They both use #KVM/qemu under the hood, so didn't seem like it was going to be a problem.

It really wasn't.

Linux VMs are a case of "export as ova from Prism Central, upload to proxmox, import, set the hardware to match the AHV VM, start it, done"

Windows VMs are a little bit harder, there's one extra step: add a VirtIO RNG device to the VM.

Job's done.

Now the complicated part: how to move a ~4TB VM when none of my test environment has 4TB of space in any one place.

Have you wondered how to create virtual machines on Linux? We are holding a Libvirt introduction workshop, so come to Labitat this Saturday at 11:00

So, to allow a linux vm to access a directory from Fedora host with virtio-9p, I'll need to run:

# semanage fcontext -a -t svirt_home_t "/some/dir"
# restorecon -vR /some/dir

Idk why sealert offers this non-working solution instead. It's really weird.:

# semanage fcontext -a -t virt_image_t 'dir'
# restorecon -v 'dir'

My friends, I'm so excited and happy to introduce a new project: the illumos Cafe!

The positive and constructive spirit of the BSD Cafe, created and maintained by all the friends who participated from day one in building a strong and friendly community, deserves to spread to other operating systems. Because there are other OSes that deserve attention, certainly more than they're getting right now.

Operating systems based on illumos (like SmartOS, OmniOS, Tribblix, OpenIndiana, etc.) are mature, stable, secure, and perfectly usable for a wide range of tasks. ZFS is native, zones are an excellent method for containerization, and bhyve and kvm coexist beautifully - and so much more, too much to list in a single post.

So from today, the illumos Cafe will stand alongside the BSD Cafe in creating a positive, respectful, and growth-oriented (but also relaxing!) environment, starting right here in the Fediverse with a Mastodon instance and a snac one.

I've written an introductory article about the project, including some technical details. I invite everyone interested to read it: https://it-notes.dragas.net/2025/08/18/introducing-the-illumos-cafe/

Choose your table, take a seat and enjoy your time at the illumos Cafe!
