           Summary: xenconsoled dies under heavy-ish load
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: danms@xxxxxxxxxx
                CC: aliguori@xxxxxxxxxx

After running an xm-test on x86_64, I usually get lots of "Unable to read from
console" errors.  This is because running "xm console foo" returns

  xenconsole: Could not read tty from store: No such file or directory

If I restart xenconsoled, I am able to attach to the domain that was already
running AND get the missing console history.

I think this happens after the 04_memset_smallmem_pos test, which causes a
console explosion on x86_64.  The DomU kernel goes crazy and floods the console
with data.

I will re-run my tests and verify that removing the smallmem test prevents the
problem from showing up.
