I think this must be something specific about your setup -- we're
not explicitly running dhcp.
In my Xen installations, I just use the distribution's normal run
level rather than doing anything special. Since we now attach
console devices to tty1 etc rather than xen/cons the
distribution's normal startup scripts just work (at least for RH9
-- I'd be interested to hear if there are problems with other distros).

Yes -- this is the current situation, but you should get the
functionality you need back later in the week: you'll be able to
run an arbitrary script to do the bridge plumbing.

I can reproduce -- this worked fine until very recently, so we
must have had a bad patch.

I've never tested this, but it sounds like a straightforward bug.

I think our original idea was to follow the scheme VMWare uses
for assigning them.
For a number of reasons, I think we're going to have to introduce
the notion of a VM Identifier that is unique across machines in a
cluster. This is important for things like migration.

This wasn't working for quite a while, because the tools hadn't
caught up with the new Xen interface. Mike fixed it on Friday
afternoon but the changes haven't been pushed out yet.

I haven't tested multiple vifs. Mike relies on them, so I'm sure
this will be made to work.

Yep, you'll get this soon.

Very useful, thanks. I'm hopeful that by the end of next week
we'll be able to declare a 2.0-alpha and hopefully get some wider
testing and comment.
Thanks,

I have domains > 0 booting under the latest release. Here's some things I'v=
e noticed:
. even though I have /etc/network/interfaces configured, eth0 just starts a=
s dhcp, even though there appears to be no dhcp daemon running. Maybe this =
is because it is running in runlevel 4?
. Domain0 has (or will have) eth0, eth1, and eth2. I want vif1.0 bridged to=
eth2, and vif1.1 bridged to eth1. I don't seem to get any say in the bridg=
ing done in domain0, xend appears to do it all itself.
. I can't get any access to dom1's console. telnet localhost 9601 just caus=
es xend to complain.
. even though I have specified mac addresses in the config file, it just gi=
ves a random one with the AA prefix. I think a locally assigned mac address=
should look like: FE:FD:xx:xx:xx:xx. A suggestion for assigning these dyna=
mically could be: FE:FD:rr:rr:vv:ii where rr =3D a random prefix (or maybe =
in a config file), vv is the vmid, ii is the interface index. rr:rr would b=
e necessary in a site with multiple xend servers.
. Destroying a domain doesn't appear to remove it from the list in "xm list=

why at the moment - the server could have been stolen for all I can tell fr=
om here :).
As i've mentioned before, i'd really like to see xend call a script when a =
vif comes up, so it can be bridged, routed, whatever, as appropriate. Ditto=
for when a vif goes down.
Hope that the above is useful rather than annoying!
