qemu-kvm.git BUG - 'Two devices with same boot index 0'

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

Hi guys, I've noticed the following regression on qemu.git HEAD:

VMCreateError: VM creation command failed:
"/root/autotest/client/tests/kvm/qemu
-name 'vm1'
-monitor
unix:'/tmp/monitor-humanmonitor1-20110119-083240-ocD9',server,nowait

-boot d
--append 'ks=cdrom nicdelay=60 console=ttyS0,115200 console=tty0'"
(status: 1,    output: 'Two devices with same boot index 0\n')

I took the liberty of splitting up the qemu-kvm command line into blocks
so I could verify the problem. So, after looking at the command line
components, it is evident that kvm autotest constructed a valid, correct
command line and somehow during the processing of the command line
qemu-kvm thinks 2 devices have the same boot index, when in reality they
don't.

Please let's look into this. I am available for any further
clarifications.

Cheers!
