The one that currently is deployed is using the same "list network and hd"
which should not work.
It will boot network but should not internally fall back to disk.
10 <os>
11 <type arch='s390x' machine='s390-ccw-virtio-bionic'>hvm</type>
12 <boot dev='network'/>
13 <boot dev='hd'/>
14 </os>
Now lets understand how/what works here...
Qemu is given both boot options (we know it will ignore the second ... or at
least we think and are told so).
... -boot strict=on ... id=virtio-disk0,bootindex=2 ...
mac=52:54:00:02:a3:f9,devno=fe.0.0001,bootindex=1
I'd expect this one to "just" netboot, but we need to understand how it got
"up" from there.
Fortunately there was a full log of the serial console on disk.
Attaching files from this test ...

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...
