Yes.

I think it's being treated as a directory because it's going to access
this stage2 file.

I do not know. The whole thing is foreign to me. But both drives are
bootable as hd0 (the only drive connected). So it makes sense that the
configuration is treating this as an hd0 based installation of the
bootloader to both drives. The part were the stage 1 and 2 are
directed to separate drives must be the 'device (hd0) /dev/vdb'
command. Again, I don't know why it isn't either 'device (hd0) (hd1)'
or 'device /dev/vda /dev/vdb' but that's what the log sayeth.
