$ /home/x/virtme-ng/vng -v virtme: waiting for virtiofsd to start virtme: use 'microvm' QEMU architecture /builddir/build/BUILD/qemu-8.1.3/include/hw/i386/pc.h:135:PC_MACHINE: Object 0x55af13219130 is not an instance of type generic-pc-machine

Running on Fedora 39, I'm getting this issues. I'm getting the same with hand-build qemu (HEAD 8f3f329f5e0117bd1a23a79ab751f8a7d3471e4b). On Fedora 38, I'm pretty sure didn't see this, not sure why though.

I'm not seeing this with qemu 8.2.1, I'll do some tests with 8.1.3 and the latest qemu from git.

Does it work if you run vng --disable-microvm?

jpirko commented 8 months ago

yeah, with --disable-microvm, qemu runs and I don't see this issue.

arighi commented 8 months ago

Alright, so this seems related to the microvm arch in qemu. I'll try to reproduce the problem locally.
