Hi colleagues,

we've faced an issue, described in 
https://bugzilla.redhat.com/show_bug.cgi?id=1020622 - when VM don't see 
virtio-scsi devices if there are 2+ connected devices (in our case there 
are block device itself and config drive). We're under Ubuntu 16.04 and 
while Redhat released fixed version of seabios (1.10.2-3), there is no 
update for Ubuntu (still 1.10.2-1).

We see two ways to work around this problem:

 1. try to replace seabios binaries (bios-256k.bin and bios.bin) with
    ones from Redhat RPM on compute nodes
 2. or use UEFI for booting images

Whether we missed others?

We will try 1st way, but I guess UEFI is more preferable long-term 
solution, since it better itself than legacy BIOS.

During googling I wasn't find any recommendations on how to prepare UEFI 
images using diskimage-builder.

Can anybody there point on documentation or give some recommendations on 
how to create UEFI images with diskimage-builder?

Thank you!
