HOST ENV:
OS : Ubuntu25.04
kerne; : 6.14.0-15-generic
qemu : QEMU emulator version 9.2.1 (Debian 1:9.2.1+ds-1ubuntu5)

GUEST ENV:
OS : Ubuntu25.04
I attached the SAN disks to my guest and enabled multipath on my lpar, when I tried to install the guest on my system after that it is failing!

Steps to reproduce:
1) Enable the multipath in the lpar
2) Start the installation of guest(plucky-live-server-ppc64el.iso with this iso)
3) I saw the error messages as mentioned above
4) When I chose the storage disk after this it got stuck
Configure a guided storage layout, or create a custom one:
(X) Use an entire disk
?????????????????????????????????
? /dev/vda local disk 10.000G ? ?
?????????????????????????????????
[X] Set up this disk as an LVM group
[ ] Encrypt the LVM group with LUKS
Passphrase:
Confirm passphrase:
[ ] Also create a recovery key
The key will be stored as ~/recovery-key.txt in
the live system and will be copied to
/var/log/installer/ in the target system.
( ) Custom storage layout
[ Done ]
[ Back ]
I clicked on the storage disk and after this the installation is just stuck at this point! Seeing this error also in dimes

Now I can see the crash happening after I destroyed and started the guest again!

== Comment: #2 - Anushree Mathur <Anushree.Mathur2 at ibm.com> - 2025-04-17 01:19:39 ==
Steps to reproduce(more clear):
1) Create a qcow2 image
qemu-img create -f qcow2 ubuntu_qcow2.qcow2 10G
2) Start the installation on this fresh qcow2 image
3) It gets stuck at the storage part of the installation and we see the error messages as mentioned in description
4) Destroy the guest and start it again, after this will see the crash
report getting generated!
