Hi Domien, Possible it is, but you will need to test this deployment. The firmware json files are stored under /usr/share/qemu/firmware on each KVM host, and the fd files are stored under /usr/share/edk2/ovmf/ on the KVM hosts, too. As far as I understand, and you need to confirm it, the Chipset/Firmware Type option in the web UI is retrieved from the PostgreSQL database requiring you to add additional entries to it so the web portal will display the corresponding options to deploy this appliance. The good point, by going this path you will be able to create a great blog article describing how to create a custom entry in oVirt to deploy Sonicwall in it.

I probably already know the answer (no) but I want to be sure.
