      Hi,

      I would like to load BootROM for my network card into the VM, the card runs with SR-IOV, so the VM gets a VF from the card. I already have the ROM extracted. It is possible with KVM, and I wonder if it would be possible to do something similar with XCP-ng.

      If it is not possible to load BootROM, maybe it would be possible to customize the BIOS / UEFI that is loaded into the VM?

      The story is that I would like to boot a diskless VM directly from SAN over SR-IOV to avoid virtualization latencies, and the card I want to use is not recognizeb by iPXE, thus loading a manufacturer Boot ROM would solve the issue.

      I know I can boot from a small "boot image" disk attached through a hypervisor, and then boot from SAN based on initrd drivers however this would make it much more complicated to provision/install multiple VMs in the cluster this way, and I would prefer a more straightforward way.

        I'm not aware of such possibility, but let me ask around 🙂

          Sure,

          Another thing is that included iPXE is a version that does not support multipath SAN boot (I guess it would be nice to update it)
