           Summary: Kernel Bug in hypervisor.c: line 192
           Product: Xen
           Version: 3.0.1
          Platform: x86-64
        OS/Version: Linux-2.6
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: Benjamin.Carleski@xxxxxxxxxxxxxxxxx


I installed Xen on SuSE Linux 10.0.  I ran the online update before starting
the computer.  After starting I created a single VM.  I loaded into that VM and
started working.  While working in the VM, I have received the "Kernel Bug in
hypervisor.c: line 192" error 5 times.  Twice happened while I was trying to
install the Rational ClearCase client.  Once happened while I was copying
network files.  The last two happened while I was trying to compile JSP files
using the jasper2 compiler from Apache.  Each time, the header to the kernel
bug report and the stack trace is the same, just with different running
applications.  Each time, I am able to exit to Dom0, but I have to destroy and
recreate the VM domain to get anything to work again.  Below is the bug report
that shows up on the console when this happens.  The first one is from the
Rational install failure.  The second one is from while compiling JSP files.
