Hi
I need the e820_host option for a passthrough of an digitaldevices
dvb-s2 card. Without this I'cant initialize the card in the domU.
On an all my domU's with high IO load like an file server I need to set
max_grant_frames = 64 or higher. Without this I get a lot of messages on
dom0/domU and kernel exceptions.
I've read it should be ok to set it = 256 on all domU's (somewhere on
SuSE pages), so if there is a possibility to set it global on
hyperviser, this could be a solution for me.
With xl.conf it is possible but libvirt doesnt look there for the
settings. I've tried to set it in libxl.conf, but this doesnt work to.

Hi
Does someone know how it is possible these parameters:
e820_host
max_grant_frames
to set with libvirt xml config?
Currently, those settings are not supported by libvirt. Do you need to
adjust them for PCI passthrough to PV domains?
I took a quick peek at xl.cfg(5) and based on the description of those
settings didn't see a counterpart in the libvirt domain schema.
Perhaps understanding use-cases will help with modeling those settings
in libvirt domain XML.

Jim
