Thanks Ian, its all good - I've withdrawn them and I'll send an announcement 
to my user list to get them to downgrade etc...

It's quite bad.  We don't understand the impact properly yet but it is
at least a domU crash in some situations.

I would withdraw the packages, yes.  Sorry.

We have discovered a bug in Xen 4.7.5 (related to shadow paging).
This bug is a new regression compared to 4.7.4 and does not affect
other Xen releases.

We are investigating the problem.  For now, we recommend that users of
4.7.x do not upgrade to 4.7.5.

Apologies for the inconvenience.


Hi Ian,

I'm wondering if the severity of this is high enough that I should 
withdraw the 4.7.5 packages from my repos.


Is this a show-stopper? Security issue? Dom0 crash?

I released 4.7.5 packages within an hour of the 4.7.5 release 
announcement - so there are quite a few user systems that have already 
grabbed them.
