Really what you're doing here is extending the IXP infrastructure inside 
the hypervisor.  I.e. the hypervisor switch is becoming an IXP switch. 
In theory there's nothing wrong with this except that several of the 
standard hypervisors don't support MIB-II for their virtual switch 
infrastructure, which means that IXP manager can't really see what's 
going on inside the switch.

If your hypervisor supports MIB-II and you can see all of the virtual 
interface in SNMP that you want to monitor, then there's no problem 
adding it in as a switch.

We solved this by using multi-port ethernet cards and using dedicated 
ports for each service.  It's not efficient but it does work.
