Emil –
Thank you! This gives me another avenue to
explore.
So what you are saying is that one does
not have to explicitly create the new interface on the VLAN by making changes
in /etc/sysconfig/network-scripts/ ? By configuring the vlan in vconfig
it builds the new interface automagically? Will this setup survive a
reboot or should I build a script to set this up each time?
In my case I have bonded two NICs (well
actually two ports on the same NIC but no need to split hairs) so I would imagine
I would replace eth0 in your example with bond0.
The host OS I am using is, I believe,
CentOS. I am using the Xen Enterprise version installed right off of the
CD which uses some RedHat derived distro.
Thank you for your help

Hi!
I'v
just recently set that kind of eviroment up. What Host OS are you running
becouse i wrote 2 diffrent howtos for Red Hat and one for SuSe.
But
in theory you just have 1 interface for ex: eth0
then
you do vconfig add eth0 VLANID
when
that is done you create a bridge something like this:
brctl addbr brVLANID
brctl
addif brVLANID eth0.VLANDID
when
that is setup you should change "network-script=network-bridge" to
"network-script=network-dummy" within your xend-config.sxp so Xend
doesnt screw up your real physical interface.
When
that is done just put: vif=["mac=XX:XX:XX:XX:XX:XX,bridge=brVLANID",]
in your domU configuration file.
If
you want more info just give me a mail and i will help you as the best as i
can.

[Xen-users] VLAN help
We are in
the process of setting up a few Xensource servers whose initial function will
be to run Exchange 2007. As part of this (and for future VM’s) I
need to be able to provide access to various VLANS to the various DOM’s.
In theory
this sounds fairly straight forward: DOM0 gets a PIF for each VLAN. This
PIF connects to a VLAN specific bridge and then, for each DOM that needs one, a
VIF is created and connected to the bridge.
Does this
sound correct?
If so, my
question is how to specify the VLAN for a PIF. I can list it but I am not
able to set it since it is read only.
How do virtual
networks fit into the above and how is a virtual network different from a
virtual bridge?
Any help or
pointers to information are greatly appreciated.
Thank you
for your help;
