RE: [Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 11686

["Ed Smith" <esmith@xxxxxxxxxxxxxxx>]

These bugs happen every time for me.  To reproduce the bug I do the
following:

- Boot a release build of XEN
- Launch a RHEL4U2-32bit HVM guest, 256MB, 2CPU SMP kernel, 4GB swap
file, local SATA disk
- ssh into the guest and run the following test:
  # while [ 1 ]; do mtest01 -v -p80; done
- Within 1 or 2 passes of the test I hit one of the several crashes
reported.
- Nothing else is running on the guest and this is the only guest
running on XEN.

Hope this helps,
Ed

We're having some difficulty reproducing these failures.  Are you
running full ltp tests or just the mtest01 binary?  Are you running
anything else in the VM at the time?  How often do the failures occur?
Was there a difference between the tests which caused the two failures
or did they happen on different runs of the same test?

Cheers,

Tim.
