If possible, help me understand things a bit better. So, can you confirm that the situation _actually_improves_ with Xen 4.10 ? Basically, as far as I've understood things, with Xen 4.9, you destroy a guest, and you can _never_ re-create it, not even after 30 seconds, 90 seconds, 2 minutes, 1 hour, ecc. Is that correct? With Xen 4.10, it may still fail, if you try to re-create it within ~30 to 90 seconds, but after that, it works. Is that also correct? I need to know this, because I want to understand if the issue is, at least partially, cured by the RCU fixes, although having to wait 30 seconds is definitely not what I was expecting (i.e., there might be something else). Another question, in case I manage to produce a debug patch, are you ok to put it in your source tree, build with it, and tell us what you see?
