chipset. Here is the test summary:

successfully

[Block issue]:

Somehow I've started corrupting memory. :-(

At least it looks easy to reproduce!

FYI, the bug is the final xfree(vlapic) in vlapic_destroy(). If that line is
removed then HVM guest destruction works again.

The patch is in the staging tree, c/s 12296:1fcdb3a35db3. It should get
pushed to the public tree fairly soon.
