SPARC64 emulation: QEMU error: qemu-sparc64-softmmu: Virtio VGA not available

[lelegard]

Hi,

I want to setup an emulated SPARC64 VM with a Debian guest OS.

• Use UTM 4.4.5 (94) on an Intel iMac (also tried on an Arm64 MacBook M1).
• Got debian-12.0.0-sparc64-NETINST-1.iso as installation image for the guest.
• Created a new emulated virtual machine, arch sun4u.

When I start the VM, I get a QEMU error: qemu-sparc64-softmmu: Virtio VGA not available

So far, I used UTM to run native VM's, not emulating other architectures.

The generated QEMU command is:

qemu-system-sparc64 -L /Applications/UTM.app/Contents/Resources/qemu -S \

    -name vmsparc -uuid E19FAA16-AC90-4092-910F-909FF610DAC2

Any idea to fix this? (needless to say that Google did not help...)
Thanks

To use the VirtIO video display, the guest OS needs a VirtIO video driver; you apparently don't have one on your install CD?

Switch displays to standard VGA or something else that the CD will have a driver for, and then play around with accelerated drivers once the base install is complete.

Hi @adespoton

And now I get a QEMU error: qemu-sparc64-softmmu: unknown vga type: VGA

Also tried all other display options from the UTM menu for the VM: cirrus-vga, ati-vga, bochs-display, secondary-vga, vmware-svga and all virtio-*.

None of the available display options in UTM work for SPARC64.
