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 = 2...

Hi Does someone know how it is possible these parameters: e820_host max_grant_frames to set with libvirt xml config? I use them with xl config but I want to change to libvirt config/tools. (with libvirt 4.10 it is possible to start pvh domains) -- ------ Greetz
