Hi guys,
I was trying to PXE boot a guest for quite some time now and I think I've
found a solution that is kind of hackish but pretty simple. I'm not quite
sure it's good to go in trunk but felt like I'd share it since I've been
messing a while on this.
If anybody have a better solution, I would really like to hear/see/try it ...
Here is how I did it:
First, patch the libvirt/driver.py file:

else:

+ guest.os_boot_dev = FLAGS.default_guest_boot_dev
if FLAGS.libvirt_type != "lxc" and FLAGS.libvirt_type != "uml":
guest.acpi = True
And add to nova.conf:
default_guest_boot_dev=network
And finally add to /etc/dnsmasq.conf
dhcp-boot=boot\x86\pxelinux.com,host_name,host_ip
dhcp-no-override
And restart dnsmasq.conf
In my actual setup, the guest will PXE boot, show the menu 60 seconds and then
boot from hard disk after the 60 seconds timeout.
Thank you very much,
Dave
