qemu-kvm doesn't exist for years, I have marked it for qemu instead. Thanks Frank for making me aware.
Sean got everything right in comment #6, it can only boot one and that is the first boot entry. There is no fallback/fallthrough on s390x. If you stick with global boot options the host would needs to change the XML to boot fro disk in this case. (BTW that is the case since the beginnign the comment is from libvirt 3.5 somewhere around zesty I think). P.S. if this ever worked it was a bug that is not to be relied upon (but I'd wonder) But that doesn't mean it won't work, just not with that XML format. I've never tested it but I think you might be able to get away with a proper bootorder config. An example can be found here [1] that you might try (do not implement it directly, give it a test please) [1]: https://libvirt.org/git/?p=libvirt.git;a=blob;f=tests/qemuxml2xmloutdata /machine-loadparm-multiple-disks- nets-s390.xml;h=c4e08fd4401bf5bf448ee45ab8890b3e44057f97;hb=HEAD ** Changed in: qemu Status: New => Incomplete -- 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: Incomplete 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.
