There is a regression in libxl's bitmap handling during a restore. I 
need libxl maintainers to decide which of the two suggested ways to fix 
it I should use. Both are fairly trivial.

There is also a bug in libxl's PCI detach code. In fact, two bugs, both 
related to a race between libxl, qemu and guest. IanJ suggested a simple 
patch for one (which, in fact, fixes a regression) but the second bug 
will probably take me a while (need to make detaching call chain 
asynchronous).

This, I believe, is queued for 3.19.
