Xen devel - Jun 2006 - Possible bug in 3.0.2 - "Manager is watching"

I call this one the "Manager is watching" bug since it *only* happens
during demonstrations.

Really.  I am not kidding.  Caused me some, er,  awkward moments not
once, but twice.

 

 

Actually, the reason may be more prosaic.  Here is the situation.

 

I am using FC4 on an EM64T host with the Xen mods - VT enabled.

 

I have two VMs.  VM1 is Win XP (32 bit), VM2 is RHEL4U1 (32 bits)
booting to run level 3.

 

In most case this works fine.  However, if I run a vnc server in the FC4
host so I can dempo the system, 

 then as soon as I start VM2, the host immediately crashes and reboots.

 

I am running the stock x11vnc server.  I am guessing that this is
related to memory, so for the record, here is how memory is setup.

 

Physical host has 2 Gig.

            Kernel /xen.gz dom0_mem=1024M

            Dom0-min-mem = 196

 

VM1 memory

            Memory = 512

 

VM2 memory

            Memory = 1024

 

When both start normally (that is, when vnc server is not running), the
memory in dom0 goes down to about 290M.

 

I am going to try and narrow things down more, but I am wondering if any
one else has seen this behavior?
