Any plans on supporting BSDs (OpenBSD/FreeBSD)

does tart have bsds on their roadmap

Tart is using VZEFIVariableStore for running "Linux" VMs which theoretically means you can try to run FreeBSD and/or OpenBSD already with Tart:

curl -o freebsd.iso https://download.freebsd.org/releases/arm64/aarch64/ISO-IMAGES/13.1/FreeBSD-13.1-RELEASE-arm64-aarch64-dvd1.iso
tart create --linux freebsd
tart run --disk freebsd.iso freebsd

Unfortunately, the commands above make the installer go in the infinite restart loop:

It seems you might need to try to prepare a special disk for EFI as described in the docs. Maybe someone from FreeBSD coomunity can weight in on how to make it work. CC @emaste

It would be good if someone could get it to work.
Anyhow thanks for the pointers.

The final message I see in the FreeBSD boot video above is Please set hw.efifb.address and hw.efifb.stride. which is from the loader, so it appears we are not actually getting as far as the kernel.

There is ongoing work on FreeBSD/arm64 as both native and virt guest on the MS dev platform and Apple arm64 platforms, so we should take a look at this in due course.

Trying to boot OpenBSD but as soon as the VM starts loading the kernel, I get:

guest has stopped the virtual machine due to error: Error Domain=VZErrorDomain Code=1 "The virtual machine stopped unexpectedly." UserInfo={NSLocalizedFailure=Internal Virtualization error., NSLocalizedFailureReason=The virtual machine stopped unexpectedly.}

Considering that I have OpenBSD running as the host OS on another mac mini m1, I thought I should be able to get it to run as a tart guest but apparently not :-(

Is there a way to make tart a bit more verbose and/or dump the current state for the VM at the time of the VZErrorDomain ?

Just tried the latest FreeBSD 14.1 (FreeBSD-14.1-RELEASE-arm64-aarch64.raw) on macOS Sonoma 14.5 with Tart 2.12.0, doesn't seem to get past Trying to fire up the kernel, but no device tree blob found!:

I was able to install OpenBSD 7.6 via install76.iso (released and current), full install, and everything but -x* worked. I was able to use the system, but without networking, it is really hard to use it.

vio0 fails with inet saying feature negotiation failed, but somehow inet6 gets an address? I was able to start xenodm, but it was just a black screen, and I had to reboot after that.

[edigaryev]

Unfortunately, we're tied with the VirtIO network driver that the Apple's Virtualization.Framework provides, so the most likely scenario of resolving this is probably a fix for feature negotiation failed on the OpenBSD's side.
