[one-users] change ebtables-xen to work with KVM?

[Shi Jin]

Thank you.
I tried it but it seems that the $VM_ID specified as the command line
argument has no value.
I got errors like:
Tue Sep 22 10:05:07 2009 [HKM][I]: Command execution fail:
'/srv/cloud/one/share/hooks/ebtables-kvm start one-'
Tue Sep 22 10:05:07 2009 [HKM][I]: STDERR follows.
Tue Sep 22 10:05:07 2009 [HKM][I]: Connecting to uri: qemu:///system
Tue Sep 22 10:05:07 2009 [HKM][I]: error: failed to get domain 'one-'
Tue Sep 22 10:05:07 2009 [HKM][I]: error: Domain not found
Tue Sep 22 10:05:07 2009 [HKM][I]:
/srv/cloud/one/share/hooks/ebtables-kvm:21: undefined method
`elements' for nil:NilClass (NoMethodError)
Tue Sep 22 10:05:07 2009 [HKM][I]: ExitCode: 1
Tue Sep 22 10:05:07 2009 [HKM][E]: Error executing Hook: ebtables-running.

When I manually run /srv/cloud/one/share/hooks/ebtables-kvm start
one-50, it does seem to work. I get
root at node1:~# ebtables -L
Bridge table: filter

Bridge chain: INPUT, entries: 1, policy: ACCEPT
-d ! 0:3:c0:a8:1:84 -i vnet0 -j DROP

Bridge chain: FORWARD, entries: 0, policy: ACCEPT

Bridge chain: OUTPUT, entries: 1, policy: ACCEPT
-s ! 0:3:c0:a8:1:0/ff:ff:ff:ff:ff:0 -o vnet0 -j DROP

Do you know what the problem is here?
Thank you.
