[Xen-devel] Bug - DomUs failing to restart - issue with maxmem_mb set to 0

[Anthony Wright <anthony@xxxxxxxxxxxxxxx>]

I have a process that monitors DomU's, and when they shutdown it spots
it and restarts the DomU.

If I restart them immediately very frequently I get an internal error,
and the DomU fails to start. If I add a 2 second sleep before restarting
the DomU, it restarts nicely. If I restart the DomU after it has failed
to start once, it will restart nicely. The xen config for all the DomUs
is identical.

I notice that in xend.log, when a DomU fails to restart the
XendDomainInfo.recreate parameters online_vcpus, maxmem_mb and mem_kb
are all set to 0. When the DomU starts correctly these parameters have
sensible values.

I'm running Xen 4.1.2 with kernel 3.3.2 all in 32 bit mode.

I'm attaching the output from xl create and the sections from xend.log.

Anthony.
