[Xen-devel] [BUG] Xen vm kernel crash in get_free_entries.

[Astarta <astarta@xxxxxx>]

Hello,

This is a some kind of a follow up to the 
http://lists.xen.org/archives/html/xen-devel/2013-09/msg03109.html (
Linux 3.11.1 HVM guest kernel crash when started with xl 
(get_free_entries)).
Looks like we've here the similar issue.

Xen VM with 3.8.13 kernel crashes in get_free_entries (kernel BUG at 
drivers/xen/grant-table.c:1181!), i.e in:
BUG_ON(grefs_per_grant_frame == 0);. 3.11.5 kernel behaves in exactly 
the same way.
Whole kernel log is attached. It does not contain  any "Grant tables 
using version" message.
Seems that gnttab_request_version() has was never executed, so 
grefs_per_grant_frame was never set.
Could you please advice on this issue?
I'm ready to provide any further information if required.
