Hi,
We just noticed an issue flagged by a libvirt based test. This same command
line didn't used to fail, and I wanted to be sure that this is behaving as
intended.
When the following command line is used on the current qemu version:
x86_64-softmmu/qemu-system-x86_64 -kernel /boot/vmlinuz -drive
file=~/disk0.raw,if=none,id=foo,boot=on -device virtio-blk-pci,drive=foo
We get the following error reported:
Two devices with same boot index 0
Previous versions of qemu did not flag this as an error condition.
Upstream QEMU does not have a boolean boot flag although I guess we
ignore it in -drive which sucks :-/
In upstream QEMU, the BIOS can boot just fine from a virtio device.
What you're seeing is that we've apparently overloaded the boot flag in
upstream qemu to mean boot index.
Gleb, what's the right invocation here?

I can see that we are indicating two different boot sources here, so I would
guess the command line is invalid, but wanted to be sure.
