pxe boot again

[Farkas Levente]

hi,
i already wrote a thread about it a long time ago:
https://www.redhat.com/archives/et-mgmt-tools/2008-May/msg00139.html
now i try it again. we've got a working pxe server and use it to install
all of our system. now i like to test it, but it still (or again) not
working.
with virtualbox 3.2 if i choose bridged networking and switch off
VT-x/AMD-V support as described in:
http://www.virtualbox.org/ticket/2536
than it's working. but with kvm not.
so is there anybody who can tell me:
- is the pxe boot working in virt-manager kvm?
- if yes, which kind of setup? ie:
  - which kind of networking to choose?
    - nat or bridged?
  - what else should i've to configure to get it working?
thanks in advance.
regards.

I think solution for KVM is simple, only need to wait aprox. 3 seconds more
for DHCP address.

Try to boot your virtual machine using virt-manager and after more than 3
seconds select from menu:
  Send Key -> Ctrl+Alt+Delete

(Do not power off your system again!)

Then PXE boot works well for me. Can you confirm this?

i forget to mention my setup is:
- fedora-12 fully updated:
  - kernel-PAE-2.6.32.14-127.fc12.i686
  - qemu-system-x86-0.11.0-13.fc12.i686
  - gpxe-roms-qemu-0.9.9-1.20091018git.fc12.noarch
  - virt-manager-0.8.2-3.fc12.noarch
  - libvirt-0.7.1-16.fc12.i686
is this bug still valid?:

bridged

IIRC nothing (besides local firewalling rules)

firewall is off, network bridged pxe hang forever here (see the attached
screen). exactly the same happened with virtualbox until we switch off
VT-x/AMD-V support.

I had a similar problem booting the gpxe image from
boot.fedoraproject.org when I experimented with it.

If I just let it do the default boot it always claimed
it had network problems. (This was in a KVM image with
bridge networking and a dhcp server on the kvm host).

If I booted then entered the command mode and manually
ran the commands to tell it to define the interface with
dhcp then boot, it worked fine.

It really was like some part of the process just wasn't
waiting long enough for the network to initialize.

Maybe pxe and gpxe share the same logic in that vicinity?
