Not able to launch guests in ppc64le P9 OPAL
Description of problem:
Not able to launch guests in ppc64le P9 OPAL
Steps to reproduce:
1. In a RHEL8 using 4.18.0-305.3.1.el8_4.ppc64le create a Fedora CoreOS VM using kernel-5.15.17-200.fc35.ppc64le. 
2. Inside the FCOS vm run:
```
virt-install --import \
    --name buildvm-ppc64le-fcos01.iad2.fedoraproject.org \
    --memory=32768,maxmemory=32768                       \
    --vcpus=16,maxvcpus=16                               \
    --feature nested-hv=on                               \
    --network bridge=br0,model=virtio,mac=RANDOM         \
    --autostart                                          \
    --memballoon virtio                                  \
    --watchdog default                                   \
    --rng /dev/random                                    \
    --noautoconsole                                      \
    --disk path=$PWD/fcos-ppc64le-builder.ign,format=raw,readonly=on,serial=ignition \
    --disk bus=virtio,path=/dev/vg_guests/buildvm-ppc64le-fcos01.iad2.fedoraproject.org,cache=unsafe,io=threads
```

3. Try to run it again and you will get:
