Re: [Xen-users] Virtual switches


Could this be what your asking? This sounds like something i've just setup with vlans using this guide and scripts

I edited the script "scripts/network-multi-vlan" to look like

   dir=$(dirname "$0")
   "$dir/network-bridge" "$@" vifnum=0
   "$dir/network-bridge-vlan" "$@" vlan=2

i then removed eth0.2 from the vlanbr2 which prevents the rest of my physical machines reaching the ip's and created a domU named gateway with 2 vifs one connected to xenbr0 and one connected to vlanbr2 like this.

vif = [ 'mac=00:16:3E:00:00:26, bridge=xenbr0, vifname=gateway.0','mac=00:16:3E:00:02:10, bridge=vlanbr2, vifname=gateway.1' ]

then i have 2 more domU's connected to the vlanbr2 that appear only to be accessible from by passing through the gateway or internally. Its all new to me though and i dare not say its secure any further advice would be welcome on that.

xen5etch:~# brctl show
bridge name     bridge id               STP enabled     interfaces
vlanbr2         8000.feffffffffff       no              gateway.1
netserv.0 net1.0
xenbr0          8000.feffffffffff       no              vif0.0
peth0 gateway.0

Hopefuly this is helpful.

Are there guides for setting up a virtual switch for use in between guest domains in Xen ?

In Xen, is it possible for a guest domain to perform a initial dhcp IP lookup from another guest domain ?
How are the configurations like ?

Are there references or step procedures ?

Kindly advice.
