Ovirt devel - Apr 2008 - [PATCH] use Fedora9 for building oVirt host images

use Fedora9 for building oVirt host images

- http://ovirt.org/repos/ovirt/9/ yum repo (incoming) contains only collectd for
now
- livecd-creator --skip-minimize to avoid osmin.img - not needed for oVirt host
- network service is not enabled by default in F9
- add serial console, workaround for F9 livecd KVM guest dying with standard
console only.
  VNC console will go blank but node will continue to boot and it's
accessible via ssh or libvirt RPC.
  You can also access it via ttyS0

  mini-howto: access serial console of a KVM guest (thanks Gerd and Chris):
  # cat > /usr/bin/qemu-kvm-serial <<EOF
#!/bin/sh

exec /usr/bin/qemu-kvm -serial telnet:localhost:10057,server,nowait
"$@"

EOF
  # chmod +x /usr/bin/qemu-kvm-serial
  then change <emulator> to /usr/bin/qemu-kvm-serial
  redefine and restart guest. telnet localhost 10057 to access guest's ttyS0

There is still the 180s delay problem with udev in this though right?  Is 
there any workaround for that yet?

I just put the repo up, for those who want to try it.

Hi Alan,
That looks good.

ACK.

One nit: the " *" parts before "console=" and
"APPEND".
If you use two spaces, "  *", or "\<", then it won't
mistakenly
match things like an imaginary noconsole=something_else option
or "DO_NOT_APPEND".

And it'd be nice for reviewers and overall readability
to keep line length < 80, e.g.,:

sed -i -e 's/  *console=[a-zA-Z0-9,]*//g' \
    -e 's/  *APPEND.*/& console=tty console=ttyS0,115200/' \
  tftpboot/pxelinux.cfg/default
