Subject: [PATCH] libxl: User defined max_maptrack_frames in a stub domain
Date: Mon, 14 Sep 2020 17:50:32 +0300	[thread overview]
Message-ID: <602469f5-1028-8f36-7195-f102b6d2af0c@tabit.pro> (raw)

Hi,

Implementing qrexec+usbip+qemu in Linux-based stub domain leads me to
an issue where a device model stub domain doesn't have maptrack entries.

Would it be possible to apply a user defined max_maptrack_frames value 
to dm_config in the same way as for max_grant_frames?
