a tracing module I was using.

node or virthost.

Enough information is logged so that, at any point in time,
it is possible to tell what images are being used.  After
collecting some stats for a while I hope to use this data to
evaluate various strategies for preloading disks with images
other than the default.

Although not its primary purpose, enough information is
collection to be able to get a snapshot of node usage at any
point in time.  This includes what nodes are being used and by
who, as in which experiments and thus which projects.

NOTE: For a while you might see a few of these warnings,
  *** WARNING: os_setup:
  ***   could not find previous state (rsrcidx=484084) in image_history
  ***   table, won't be able to determine newly allocated nodes
if someone does a swapmod to an experiment that was swapped in
before this commit was installed.  This is because os_setup uses
previous information in the table to determine newly allocated
nodes.  This warning can safely be ignored in this case, and should
go away over time.

<available> is now based on reality. interface node_uuids are also real. TODO: link_uuid, virtualization_type, (null) interface name.

ptopgen now generates a file which validates under the new rspec schema. ptop/ptopxml are identical. Some of the rspec output is still placeholder.

so that I can use it from the protogeni code.

cause the switchs does not create any vlans, and so there is nothing
to trunk with.

to allow elabinelab vlan firewalls. Alas, I never got there, fell into
a pit of hell and never made it back out. However, I did do a few
things.

I did make some changes to deal with stacks, mostly making sure that
stacks are processed properly inside the elabinelab, and passed
through to the outer emulab, which currently ignores the stack. See
the new version of the proxy.

The big change was to -m and -o. These now require a pid/eid argument
so that we can create (and delete) vlan objects in the DB, for both
the control and experimental stacks. Most notably, when creating a
firewalled experiment, we get a Lan(VLan) object for the control
network fwvlan, and an entry in the softstate vlans table (that
mirrors what is on the switches). This is intended to make things
easier to cleanup after a swap error, and to catch inconsitencies
before we release nodes. Note that -m and -o take -f to override the
pid/eid requirement, in which case they operate as before.

Trunk enable/disable and Port enable/disable now record that state in
the new interface_state table.

We now proxy doPortControl().

A second -l option overrides Keiths change that prints only vlans
associated witl experiments; print *all* vlans.

interface_state table.

Instead of passing along a set of arguments that needs to be turned
into command line arguments to the proxy, pass along an xmldoc
representing the arguments. This xmldoc is passed through the rpc
server to the snmpit proxy, where it reconstructs the arguments. This
avoids all that cruftiness in the rpc server (also error prone) and
make it easier to add new remote methods, say for supporting eventual
elabibelab firewalls. Note that there are currently two versions of
the proxy and two methods in the rpc server, so that existing emulabs
will work.

I also added support for port enable/disable/etc from the inner elab.
There is also the beginning of firewall support. I pass the stack
module argument along, but currently not actually doing control stack
operations from the proxy. Needs more work.

Oh, I copied the cvs repo file for the original proxy so that we do
not lose the cvs history.

changes.

Removed '+' prefix from metric feature names. They should not be additive, and even if they were, the '+' prefix doesn't accomplish that goal.

longer used and the later is how idleswap works.

Finally checked in a refactoring of ptopgen's output code. This includes making rspecs mor rspec-y rather than just a slight variation of the ptop xml format.

node_attribute with key='protogeni_exclude'. Primitive, but since
there is a web interface and a backend script, its easy for remote
sites to use.
