           Summary: Xen domain scheduler allows only 50% physical cpu usage
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: habanero@xxxxxxxxxx


Xen-unstable allows only 50% of physical cpu to dom0 (and probably other domains
as well).  Running cpu bound tasks shows only 50% cpu time allocated to dom0 and
performance is generally 1/2 or less of native Linux.  Both SEDF and BVT
schedulers show same problem.
