It took some time (due to travel), but I was now able to do a setup based on the old 2.6.0 version [2.6.0 (7803-g6fc5f26eb- 0ubuntu1~18.04.1)] for testing.
And with the combination: $ apt-cache policy maas maas: Installed: 2.6.0-7803-g6fc5f26eb-0ubuntu1~18.04.1 Candidate: 2.6.0-7803-g6fc5f26eb-0ubuntu1~18.04.1 Version table: *** 2.6.0-7803-g6fc5f26eb-0ubuntu1~18.04.1 500 500 http://ppa.launchpad.net/maas-maintainers/testing/ubuntu bionic/main s390x Packages 100 /var/lib/dpkg/status 2.4.2-7034-g2f5deb8b8-0ubuntu1 500 500 http://us.ports.ubuntu.com/ubuntu-ports bionic-updates/main s390x Packages 2.4.0~beta2-6865-gec43e47e6-0ubuntu1 500 500 http://us.ports.ubuntu.com/ubuntu-ports bionic/main s390x Packages and: $ apt-cache policy qemu qemu: Installed: (none) Candidate: 1:2.11+dfsg-1ubuntu7.21 Version table: 1:2.11+dfsg-1ubuntu7.21 500 500 http://us.ports.ubuntu.com/ubuntu-ports bionic-updates/universe s390x Packages 1:2.11+dfsg-1ubuntu7.20 500 500 http://ports.ubuntu.com/ubuntu-ports bionic-security/universe s390x Packages 1:2.11+dfsg-1ubuntu7 500 500 http://us.ports.ubuntu.com/ubuntu-ports bionic/universe s390x Packages the system seems to successful commissions, similar to the latest maas 2.6.2 version (see above). But then the VM ends again in state Ready / off. virsh shows the VM as shutoff: ubuntu@s1lp11:~$ sudo -H -u maas bash -c 'virsh -c qemu+ssh://ubuntu@192.168.122.1/system list --all' ubuntu@192.168.122.1's password: Id Name State ---------------------------------------------------- - vm1 shut off The os element looks like this - with the two entries: <os> <type arch='s390x' machine='s390-ccw-virtio-bionic'>hvm</type> <boot dev='network'/> <boot dev='hd'/> </os> A manual start (with the help of virsh, console enabled) shows that it network boots (see attachment). Removing the network entry and booting didn't work - looks like no OS deployed on disk yet. To sum it up - also not working on this 2.6.0 env. that I've just created. ** Attachment added: "boot_console.txt" https://bugs.launchpad.net/ubuntu-z-systems/+bug/1859656/+attachment/5323507/+files/boot_console.txt -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1859656 Title: [2.6] Unable to reboot s390x KVM machine after initial deploy Status in MAAS: New Status in QEMU: Incomplete Status in Ubuntu on IBM z Systems: Triaged Bug description: MAAS version: 2.6.1 (7832-g17912cdc9-0ubuntu1~18.04.1) Arch: S390x Appears that MAAS can not find the s390x bootloader to boot from the disk, not sure how maas determines this. However this was working in the past. I had originally thought that if the maas machine was deployed then it defaulted to boot from disk. If I force the VM to book from disk, the VM starts up as expected. Reproduce: - Deploy Disco on S390x KVM instance - Reboot it on the KVM console...
