This looks like your installation of QEMU is completely broken.

As confirmed on IRC:

    /usr/bin/qemu-system-ppc64: relocation error: /usr/bin/qemu-system-
ppc64: symbol fdt_check_full version LIBFDT_1.2 not defined in file
libfdt.so.1 with link time reference

Please consult Ubuntu's guidance to re-install virtualization packages
properly.

Bug description:
  Hi All,

  I have a rocky setup. I am unable to launch instances on one of the
  compute nodes.

  I see the following error in the conductor logs and the libvirtd
  service on the compute. The host is ubuntu 18.04:
