I had completely forgotten that you did a tool like this before.

Here is one I implemented myself,

https://github.com/xenserver/xen-4.5.pg/commit/ec99115818abd1a98f04d5fae2481803ad21db2a

I was specifically trying to make an extendible tool to avoid the
currently state of having $N single-purpose tools, and hopefully
replacing some of the other tools in a more consistent fashion.  e.g.
xen-hvmcrash will only crash an hvm domain, but could very easily be
made to do the same to a PV domain (even using the same hypercalls I
believe, now that some PVH relaxing has occurred).

I have half an extension to this tool which will allow you to dump
various PV rings in the guest, and would like to see about merging
xen-hvmctx and xenctx together into this tool.

Thoughts?
