The issue seems to be my version of Xen (XenClient XT) must not support ballon drivers. Any call to the memory_op hypercall to change the reservation terminates my guest with extreme prejudice. I'll take that one up with Citrix. However, can someone explain why mapping a grant needs to manipulate the balloon reservation? Specifically, in the 3.7-RC7 linux kernel tree, the file drivers/xen/balloon.c:
At line 512 it tries to get a page out of the balloon. This returns null (no page). If page.... at line 513 evaluates to false At line 518 the else block calls decrease_reservation().
