(I'm not sure current-users is the best place to discuss this, but I
don't know for sure where would be better -- it is current I'm running)
So I've got a beefy Mac Pro desktop and I've been wanting to run NetBSD
VMs in it. For years I used to run VirtualBox for this, but in recent
times it is absolutely hopeless at allowing NetBSD VMs to keep good
time.
So since macOS now has its own hypervisor (Hypervisor.framework, and now
since macOS 12 a Virtualization.framework too) I wanted to try it.
There's a package called UTM (https://github.com/utmapp/UTM) that helps
manage VMs using QEMU with hardware acceleration via the macOS
hypervisor.
I set up a test VM with UTM sometime last year, but the networking
seemed a little unstable. I'm not sure that's resolved yet. It seems
like it might be a macOS problem with the underlying bridge disappearing
or changing. The VM still thinks the interface is up, but packets from
either side stop being delivered anywhere.
Anyway, yesterday I installed a new VM with a new build of -current and
I tried a couple of different configuration options vs. the year-old
build I had been testing before.
One change was to try using a SCSI emulated device for the primary disk.
This did not work well -- it was fairly fast, but often seemed to hang,
causing time outs and bus resets. I was unable to get very far in the
installation and gave up.
So I reverted to IDE, which has been reliable, but seems about 1/3 the
speed of the SCSI emulation.
So, my main question is with the device emulations available in QEMU,
which do people have the most luck and performance with?
For the curious here's a dmesg.boot:
