xen gnttab problem

Christoph Kaminski-2

I can set the gnttab frames with gnttab_max_frames=256 as hypervisor
boot parameter.
It seems to be working for the dom0:

xen-diag gnttab_query_size 0
domid=0: nr_frames=1, max_nr_frames=256

but not for domU's:

xen-diag gnttab_query_size 2
domid=2: nr_frames=32, max_nr_frames=32

This causes problems in domU with lot of IO (example 5 virtual hd's as
NFS or/and SMB server). They hang if it want to use >32 frames.

it is possible that you set the value=32 for domU's in xen/kernel
