For my debugging pleasure I have added another domctrl to call trace_var
from xc_save. That works as expected.

However, it adds additional pressure on the tracebuffer because each
hypercall is traced as well. My question is:

Would an additional domctrl (or whatever), or another trace hypercall be
acceptable? Another hypercall would at least have a chance to be ignored
by trace_hypercall() without poking into other hypercalls internals.
