Blacklisting virtio_blk

The virtio_blk module must not be loaded before the IPU is configured to run correctly. The following command prevents the OS from loading virtio_blk on boot.
host# echo "blacklist virtio-blk" >> /etc/modprobe.d/blacklist-virtioblk-smartnic.conf
If it is not blacklisted, the server may fail to boot before the IPU is properly configured to run all PVFs. This configuration is persistent across system restarts.
