Didn't actually implement anything. Worse, it looks like we don't even
pause the domain, so it's always live (not good). What's going on?
What do you mean? Why do you think "it looks like we don't even
pause the domain"? The following code of the patch looks like
we do pause domain by server.xend.domain.pause(dom).
You are doing this stuff in xm which I missed due to the pointless
passing in of 'live' and 'crash' in the xend API.
This should be happening in the server not in the client if you're going
to pass the options in. In particular libvirt, but anything else that
isn't 'xm', is forced to do live dumps - not good.
I'll send a patch out shortly that implements them in the proper place.
Yes, I agree with you. I also think it is not good.
We implemented it before for improving xend downtime at dump-core.
