After discussing with my Friends working on KVM on s390x I found the following to get me "extra consoles onto unix sockets". The default as mentioned is a sclp console and that is required for early messages and also the recommended and tested one.
For further consoles they recommend to use virtio-serial/virtconsoles. Based on the feedback I constructed these parms for my adt qemu: -device virtio-serial -chardev socket,path=/tmp/testadt/ttyhvc,server,nowait,id=ttyhvc -device virtconsole,chardev=ttyhvc,name=org.fedoraproject.console.ttyhvc That gives me a login prompt on /tmp/testadt/ttyhvc just as adt needs it. I first thought it might need a modification like "console=hvc0" as kernel commandline. But the hvc consoles seem to be auto-initialized if existing - so no change inside the guest needed. So the current default: -serial unix:/tmp/autopkgtest-virt-qemu.84_ut07n/ttyS0,server,nowait -serial unix:/tmp/autopkgtest-virt-qemu.84_ut07n/ttyS1,server,nowait should for s390x be converted to use the one outlined above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1630909 Title: failing console access on s390x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/autopkgtest/+bug/1630909/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
