The error message comes from the boot record of your disk, not from SeaBIOS. (In reply to comment #2) > The error message comes from the boot record of your disk, not from SeaBIOS. If booting from disk fails, shouldn't Seabios try to boot from other device, like NIC(depends on bootindex specified in cli)? QE was testing how Seabios behaves on boot failover. It is proved that Seabios could try to boot from NIC if fails to boot from virtio disk with bootindex specified in cli. It cannot, because the boot succeeded. The boot code in the disk however does nothing but an infinite loop. The "bug" is not in SeaBIOS, it is in the disk boot sector which you cannot control. Similarly if boot from NIC did not failover you would open a bug on gpxe, not seabios. (In reply to comment #4) > It cannot, because the boot succeeded.

Thanks for your clarification. I retried with a fresh disk---no partition/fs on it, and failover works well. |
