Connect PowerPC and ARM VMs' serial ports to autopkgtest-virt-qemu' sockets

Ryutaroh Matsumoto requested to merge ryutaroh/autopkgtest:arm-ppc-virtio-serial into master

This is a minimal change to support ARM and PowerPC VMs. This MR does two things:

  • Add one virtconsole to a ARM and PowerPC VMs
  • Connect the default serial port and newly added viriconsole to autopkgtest's sockets.

Backgroud:

  • PowerPC VM has a serial port called /dev/hvc0 and it is the console showing BIOS boot messages etc. The newly added virtconsole is named /dev/hvc1
  • ARM VM has a serial port called /dev/ttyAMA0 and it is the console showing BIOS boot message etc. The newly added virtconsole is named /dev/hvc0.

Because of the above, agetty should be attached to /dev/hvc0 in PowerPC VM while agetty should be attached to /dev/ttyAMA0 in ARM. The root shell has to be attached to /dev/hvc1 in PowerPC and /dev/hvc0 in ARM. I prepared disk images with these setup at http://153.240.174.134:64193/autopkgtest-VM-virtio-serial/

On my Debian Bullseye amd64 notebook, I tested this MR in the following way with the above disk images and I have seen no problem:

  • autopkgtest -u debci -B bash -- qemu -q qemu-system-ppc64le --debug --show-boot --timeout-reboot 1200 /var/tmp/autopkgtest-sid-ppc64el.qcow2
  • autopkgtest -u debci -B bash -- qemu -q qemu-system-ppc64 --debug --show-boot --timeout-reboot 1200 /var/tmp/autopkgtest-sid-ppc64.qcow2
  • autopkgtest -u debci -B bash -- qemu --efi -q qemu-system-aarch64 --qemu-options='-machine virt -cpu max' --debug --show-boot --timeout-reboot 1200 /var/tmp/autopkgtest-sid-arm64.qcow2
