Replace hanging virt-copy-out commands

Replace hanging virt-copy-out commands

Most often virt-copy-out just hangs on the LinuxFoundation Jenkins build
slaves until timeout exceeds and Jenkins interrupts the build. Nested
virtualization required by virt-copy-out (via qemu-kvm) seems not
stable. This is purely a workaround for LF Jenkins.

Example trace of the issue with virt-copy-out:

        /usr/libexec/qemu-kvm \
                -global virtio-blk-pci.scsi=off \
                -nodefconfig \
                -enable-fips \
