OK - found the problem !
setting my Dom0 memory with dom0_mem=2G as kernel parameter fixed the problem !!
before i haven't specified anything - so if i understand it right all the memory would
belong to Dom0 and every DomU that starts 'grabs' a bit until Dom0-min-mem is
reached.
so does this behaviour then indicate that something with balooning is buggy ??
thanks Stephen and Yongkang for the help so far !
Matthias

Hi Matthias,

I am not quite clear about the dom0 memory. Is it 3.5G?
How large the memory apply to dom0? I mean how about dom0_mem=.
Best Regards,
