Hi Angel,
With vSwitch, every server still has its own switch, but it allows switches on
multiple servers to be controlled through a central controller. If you look at
a collection of xcp servers as a single entity (pool), such a controller is
able to provide an abstraction for the switches inside the servers, so it looks
like one big switch. This central controller is not part of the open source xcp
package.
The implementation of vswitch in xcp is still very new, and unfortunately there
is not a lot of documentation yet. All the XenAPI networking functionality,
however, abstracts from the underlying implementation (linux bridging or
vswitch), so if you use this, you do not have to worry about the details. I
haven't really looked at the xsconsole extension yet, but I suppose it just
provides some more fine-grained control for the vSwitch of the server it runs
on.
Cheers,
Rob

But then, what is the configuration under Network and Management
Interface -> vSwitch of the xsconsole?
As far as I know (just a little bit) vSwitch (at least, vmware v1000
and vswitch says it is like v1000) is to create a virtual switch, shared
by all of the virtualization servers, not just a replacement of vanilla
bridge (where each virtualization servers has its own and independent
bridge). Do I have to configure any for this in xcp? How? (I haven't
found any mention to vswitch in xcp documentation)
