Closing the loop on this... I upgraded the guest to SP5 and everything is
working normally again.

I have a SLES15 SP4 system running under KVM on a z13s that refuses to IPL
after upgrading from SP3. The failure message is "! Cannot read stage2 boot
loader !". I've IPLed into a rescue shell from the SP4 ISO, set up a chroot
environment, and re-ran grub2-install with no obvious errors. Still
I'm attempting to install RHEL 6.10 under KVM on a z13s and haven't been able
to get the installer to IPL. When I try to IPL off of the ISO it fails with:
LOADPARM=[]
Using virtio-scsi.
SCSI CD-ROM detected.
! Cannot IPL this ISO image !
When I try to do a direct kernel IPL it fails
Greetings,
Will QEMU using TCG instead of KVM emulate CPU features that are missing on the
host processor? Specifically, will it emulate ESA/390 architecture on a z14 or
z15 with this config:
z900.3
for example?
I've already confirmed that config doesn't provide features from newer
Closing the loop... I got the system up and running under KVM. I hadn't seen
Viktor's message yet but I did basically the same steps.

I have a number of Linux guests running under z/VM. I'd like to move some of
them to a KVM host running in another LPAR. Naively I tried DDRing a guest's
disks to new volumes and IPLing off of the new volumes. No luck, the virtio
modules aren't available in the guest so it can't see any DASD.
8 requires z13 or later hardware, you could use either z/VM 6.4
or 7.1.

Anybody want to chime in on this?

Thanks Vic
Thanks Victor. So RedHat 8 requires z/VM 7.1? The "IBM tested and Partner
certified Linux environments chart" at
https://www.ibm.com/it-infrastructure/z/os/linux-tested-platforms covers only
hardware requirements, not z/VM requirements.

How about z/VM - what's the minimum version required to run RHEL8 guests? I've
reviewed the docs at
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/8/,
including
They're both in the SDK repo.

More info...
I'm setting up a KVM-hosted guest in a SLES12 VM running under z/VM and I'm not
able to get networking going in the KVM guest.
Host: z/VM 6.4
KVM host: SLES12SP4
KVM guest: SLES12SP4
(The KVM host must run under z/VM; I don't have any control over that.)
The KVM guest's network is defined as:
16 matches
