Looks like the issue is resolved. I tried creating a guest to capture error logs. But surprisingly I was able to create a guest in the first attempt itself.
I had used the same command I mentioned above. qcow2 creation: qemu-img create -f qcow2 /var/lib/libvirt/images/data/ubuntu.qcow2 100G Guest creation: virt-install --name ubuntu --ram 2048 --disk path=/var/lib/libvirt/images/data/ubuntu.qcow2,size=8 --vcpus 4 --os- type linux --os-variant generic --network bridge=virbr0 --graphics none --console pty,target_type=serial --cdrom /var/lib/libvirt/images/noble- live-server-ppc64el.iso ISO used: https://cdimage.ubuntu.com/ubuntu-server/daily-live/current/noble-live-server-ppc64el.iso (Downloaded just before trying this) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055126 Title: Unable to bring up a guest using 24.04(Noble Numbat) ISO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2055126/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
