i noticed the following Problem:

if i want to allow dynamic memory management of Linux-domains, i need to
set the following kernel parameter. Otherwise it is not possible, to
increase the memory of the domain above the initial assigned value:

extra = "mem=10240M"

But now it is not possible to migrate the domain. If try an offline
migration, the xm-command hangs forever.

One time i tried a live migration, the domain just disappears. The
domain was neither running on the src-domain-0 nor on the dst-domain-0,
the domain just vanished.

As promised I am starting slowly to get bugzilla a bit sorted. As I
did not work much with memory management scenarios, I'd like to know
if this might be connected to this bug:


Otherwise I'd close this bug as ian suggested to close everything
older than some months.
