...G_DEBUG_LEVEL=9' is useful for trouble-shooting as it makes the virtio drivers more verbose, but not mandatory to have. Serial line support is needed to get output: CONFIG_DEBUG_SERIAL=y CONFIG_DEBUG_SERIAL_PORT=0x3f8 Also I think rom size must be 128k b/c kvmtool expects it to be that way: CONFIG_ROM_SIZE=128 But those are the defaults, and after "make olddefconfig" you should already have them ... cheers, Gerd [1] kernel doesn't find pci (can be worked around by tweaking kernel command line in boot loader config). [2] kernel virtio drivers fail to initialize (probably device...

It was the ROM_SIZE one as it seems, it was set to 0 here. Anyways, I debugged it for a bit a found that seabios attempts to write to the notification BAR, I look further tomor...
