I use two Chromebooks and my “normal” laptop. On the ladder one I installed Chrome OS as well (brunch version) and there I installed the Linux subsystem. This is Debian bullseye. I installed qemu-kvm (including all dependencies) and virt-manager.
I started the virt-manager and installed Haiku beta 3 with the default settings. I only raised the RAM to 14 GB and use 4 CPU. Haiku works fine.
One (not so) funny thing is the cursor. I see the Haiku cursor, which is under a very little black window. I have no explanation for it. This only happens in Haiku.
I have some other VM’s with the same settings and there is no black window over the cursor.
If sombody likes to use Haiku in Qemu I suggest to try virt-manager. It works fast and stable.
