Bug 788263

Thanks for the report. Enabling the boot menu should not be required to make PXE boot work. So I assume this is a bug.

Please provide the non working qemu command line and the working qemu command line, but should be in /var/log/libvirt/qemu/$vmname.log

This likely is not a virt-manager issue though, so reassigning to kvm

first two command lines did not work, last one did. Created new VM in virt-manager, told it to install from CD-ROM. When it booted off the CD-Rom image, shut it down. Went into details, turned off CD-ROM boot option and turned on PXE boot option. It failed to connect to the DHCP server (which is on another VM). Then turned on "Enable boot menu" and it connected and brought up the cobbler/pxe menu (blue rectangle)

I also was wondering how it would behave if I created the machine with the install from PXE boot selected. That also failed in the same way, and was fixed in the same way by "Enable boot menu"

what's your qemu-kvm version?

'-boot' option is used to setup the boot order. The default boot order is "cad"
disk->floppy->cdrom  (no network),

If you want to boot from network, 'n' should be assigned by -boot option.
and 'menu' is unnecessary.

bootindex is just used to set a boot list for devices

eg: qemu-kvm -boot n -device virtio-net-pci,netdev=id1,bootindex=2 -netdev tap,...
                     -device virtio-net-pci,netdev=id2,bootindex=1 -netdev tap,...

qemu would boot from second nic, it will not work without '-boot n'

It seems that it's not a bug.

If you want to boot from network, assign 'n' by '-boot' option,
Or use bootindex for net device.

Sorry, it's wrong (I didn't test with seabios)
boot and bootindex are mutually exclusive, they could not be used together.

only bootindex should be used, -boot as a way of specifying boot order is deprecated. -boot flag should be used to enable boot menu only "-boot menu=on".

So I see two bugs here. Firs is that when "enable boot menu" is specified in virt-manager it uses -boot to specify default boot order instead of bootindex. Second is that -boot order=n works, but bootidex does not.

What is your seabios version?

try disk first (failed), then try network (success) (it's expected)

I tested with latest qemu-kvm/seabios, bug doesn't exist.

I could not reproduce this bug with seabios-0.6.1.2-3.el6.x86_64 & qemu-kvm-0.12.1.2-2.209.el6.x86_64 (which are the standard packages in RHEV3.0 & RHEL6.2)

I would close this bz as WORKSFORME. 

Hi John Holland, please reply this bz if you have some confuse.
