[Fedora-xen] help w/ xen & fc5 - unable to access network w/ dom0

I have a straight install of FC5 & xen, xen starts but does not allow
network access, if I run network-bridge stop, I can ping/access network?

 

 

Any ideas? I have tried setting the interface to onboot=no, but that did not
help

 

Thanks

RE: [Fedora-xen] help w/ xen & fc5 - unable to access network w/ dom0

My issues is that networking breaks when xen starts, I installed FC5 w/ only
1 NIC so it doesn''t appear to be swapping around as networking works
100% w/
the non-xen kernel

Re: [Fedora-xen] help w/ xen & fc5 - unable to access network w/ dom0

Sort of.  I''m currently using a custom network-bridge-dell script in
/etc/xen/scripts/ that looks something like this (the following was sent
to me by Dirk Allaert from the Dell linux-poweredge list):

=BEGIN
#!/bin/bash
# Exit if anything goes wrong.
set -e

# First arg is the operation.
OP=$1
shift

script=/etc/xen/scripts/network-bridge

case ${OP} in
  start)
        $script start vifnum=1 bridge=LAN netdev=eth0
        $script start vifnum=0 bridge=DMZ netdev=eth1
        brctl delif LAN vif0.1
        brctl delif DMZ vif0.0
        brctl addif LAN vif0.0
        brctl addif DMZ vif0.1
        ;;

    stop)
        $script stop vifnum=0 bridge=LAN netdev=eth0
        $script stop vifnum=1 bridge=DMZ netdev=eth1
        ;;
    status)
        $script status vifnum=0 bridge=LAN netdev=eth0
        $script status vifnum=1 bridge=DMZ netdev=eth1
        ;;

    *)
       echo ''Unknown command: '' ${OP}
       echo ''Valid commands are: start, stop, status''
       exit 1
esac
=END

I then add "(network-script network-bridge-dell)" in my
xend-config.sxp
file.

I haven''t been able to figure out exactly why the default
network-bridge
script doesn''t work.  I''ve tried all kinds of tricks
(ifcfg-eth*/udev/ifrename/name_eths) to make the default Xen scripts
work, but I''ve made no progress.  What''s odd is that if I
disable one of
the NICs in the BIOS, I can''t get anything to work with Xen (not even
the network-bridge/brctl tricks).

RE: [Fedora-xen] help w/ xen & fc5 - unable to access network w/ dom0

It is interesting that you have no luck w/ turning off a NIC in the BIOS, as
that is what I did, it works fine w/o xen, but as soon as I go into xen ,
nothing

Did you just re-enable the NIC or do a re-install after enabling the 2nd
nic?

Thanks
Dan

Re: [Fedora-xen] help w/ xen & fc5 - unable to access network w/ dom0

Sorry, I wasn''t very clear on this.  Network is fine without Xen.  I
just use the HWADDR directive in my ifcfg-eth* files to fix the NIC
ordering problem.  The problems I described deal primarily with Xen.
