autopkgtest-buildvm-ubuntu-cloud --arch riscv64 fails

[Heinrich Schuchardt]

The parameters for qemu-system-riscv64 issued by autopkgtest-buildvm-ubuntu-cloud are incorrect:

$ autopkgtest-buildvm-ubuntu-cloud -v --arch riscv64 --release noble

This is the used QEMU command:

The parameter "--machine virt" is missing.

[Heinrich Schuchardt (xypron)]

In salsa.debian.org the following patch fixes the problem:
bba96eee4c57 ("qemu: Use -machine=virt for riscv64")

The patch is contained in branch debian/5.30.

[Paride Legovini (paride)]

We are in the process of merging autopkgtest from Debian (version 5.31.1); this bug will be fixed once that's done.

[Tim Andersson (andersson123)]

I've raised this with the team - we're planning on soon getting up to date with debian, which would include the fix for this bug. We just need to decide if it's worth patching before we do that :)

[Heinrich Schuchardt (xypron)]

Hello Tim,

I would deem upgrading from Debian in this cycle as adequate.

Thanks for driving this.

Best regards

Heinrich

@Heinrich Noble now has autopkgtest 5.32, however

autopkgtest-buildvm-ubuntu-cloud -v --arch riscv64 --release mantic --ram-size 2048

and

autopkgtest-buildvm-ubuntu-cloud -v --arch riscv64 --release noble --ram-size 2048

both get stuck on my system after some OpenSBI messages. I can see `-machine virt` being passed to qemu now: the full commandline I see is:

qemu-system-riscv64 -machine virt -m 2048 -smp 1 -nographic -device virtio-net-pci,netdev=net0 -netdev user,id=net0,hostfwd=tcp:127.0.0.1:10022-:22 -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0,id=rng-device0 -monitor unix:/tmp/autopkgtest-qemu.jbultyp6/monitor,server=on,wait=off -virtfs local,id=autopkgtest,path=/tmp/autopkgtest-qemu.jbultyp6/shared,security_model=none,mount_tag=autopkgtest -device virtio-serial -chardev socket,path=/tmp/autopkgtest-qemu.jbultyp6/hvc0,server=on,wait=off,id=hvc0 -device virtconsole,chardev=hvc0 -chardev socket,path=/tmp/autopkgtest-qemu.jbultyp6/hvc1,server=on,wait=off,id=hvc1 -device virtconsole,chardev=hvc1 -serial unix:/tmp/autopkgtest-qemu.jbultyp6/ttyS0,server=on,wait=off -drive index=0,file=/tmp/autopkgtest-buildvm-ubuntu-cloudht0_5oo_/mantic-server-cloudimg-riscv64.img,format=qcow2,if=virtio,discard=unmap -drive index=1,file=/tmp/autopkgtest-buildvm-ubuntu-cloudht0_5oo_/autopkgtest.seed,format=raw,if=virtio,discard=unmap,readonly

Do you hit the same issue? Are you perhaps able to spot other issues specific to riscv64? Thanks.
