Due to lack of knowledge I experimented with BIOS VT-d settings "Remap
Interrupt enable" and "Remap DMA enable".
No difference in any combination.
Is there anything else I can provide to help narrowing down the problem?
Has anybody else ever tried such a VM (using character special file as
virtio-blk backend together with a passthru device)? With success?

Thanks,
