Xen users - Oct 2006 - DomU free mem history

Hello,

I''m wondering if there is any better way to get the memory usage of all
DomUs from Dom0. Currently I''m logging into each DomU via ssh, running
free -m, parsing the output and returning the memory which is unused and
the allocated swap. But therefor I''ve to install several things
(ssh-key)
in each DomU. I''d like cut down this effort. The goal ist to optimize
the
memory assignment. And no, I don''t want to Virtuozo XEN :-)

As noone else suggested something yet like some virtual filesystem that
is mountes on /proc/xen/something and read/writable on dom0/U my
2cents to solve the problem:

- nfs-server on dom0, domU mounting it r/w and a script that runs on
each domU does while true; do free >/mnt/domU_name; sleep 10; done
- using ssh-multiplexing you establish one ssh-process that logs into
each domU from dom0. Each additional ssh-command now uses the already
established multiplex-socket, speeding up the command a lot.
Read on this on the ssh_config manpage.
