I don't think you have successfully determined that the issue is in the guest driver as opposed to the hypervisor: if anything *Assertion failed: (n >= 2 && n <= BLOCKIF_IOV_MAX + 2), function pci_vtblk_proc, file /usr/src/usr.s bin/bhyve/pci_virtio_block.c, line 324.* from your original message seems to point to bhyve and thus FreeBSD. In order to track down the problem, you could try using the same virtual hardware configuration but install Linux or FreeBSD as the guest OS: if none of those work, then either bhyve's implementation of virtio-blk is buggy or you're trying to do something that's simply not supposed to work. If those work but Windows doesn't then the problem is likely in virtio-win and you should report it to their bug tracker. -- Andrea Bolognani / Red Hat / Virtualization
