Sorry, I naively ran solely the syntax checks when rebasing this series.
The ACL checks require dconn and def, and consequently the call to fetch def:
def = libxlDomainMigrationPrepareDef(driver, dom_xml, dname);
Requires dom_xml and dname being fetched from params.
Given all these dependencies having this common function for both prepare
functions doesn't seem to be doing much, as the top-level functions would end up
being very similar after these dependencies. Which makes me wonder if we should
dropped this (i.e. remove this PrepareCommon function) instead and go like
initial v1 (same comment would be applicable for the PrepareTunnel3Params in
patch 3). What do you think?
