           Summary: Jumbo frame support
           Product: Xen
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: ganto82@xxxxxx

So far it's possible to use Jumbo frames when manually setting the MTU size of
the virtual interface of a domU after creation (only tried with PV hosts). If
also the physical interface on dom0 and the interface of the guest supports it,
it's possible to send Jumbo frames to the outer world. 

But still it's not possible to send Jumbo frames between two domUs inside the
same dom0. Even when both vifs and the guests are configured to use Jumbo
frames. I tried with Xen-3.2.0 but also couldn't find anything related in the
Xen-3.3.0 changelog. Could you please have a look at this?

Many applications especially all kind of network storages would heavily profit
from Jumbo frame support.
