This is roughly right, but thinking about it, you want ts-logs-capture
to run even if the previous steps fail.

I think it might be better to reuse (subvert?) the existing machinery
in sg-run-job, by adding the l1 to need_xen_hosts.

Maybe something like

  proc add-xen-host-retrospectively {ident} {
      global need_xen_hosts
      ts-leak-check $ident + basis
      lappend need_xen_hosts $ident


And then call

  add-xen-host-retrospectively l1

at the appropriate point.

If you do this then the main run-job proc will automatically do the
leak-check and the logs-capture for you.

Thinking about this leads me to ask another question.  Suppose that a
bug causes the l1 to lock up completely.  ts-logs-capture will attempt
to hard reboot a locked-up host.  If it can't fetch any logs, it calls

What will that do if $ho refers to the l1 ?  It relies on the power
method.  Does your nested l1 "host" have a power method ?
