Re: [PATCH v2 6/7] vdpa: move iova_tree allocation to net_vhost_vdpa_init

[Si-Wei Liu]

Hi Eugenio,

Just to answer the question you had in the sync meeting as I've just 
tried, it seems that the issue is also reproducible even with VGA device 
and VNC display removed, and also reproducible with 8G mem size. You 
already knew that I can only repro with x-svq=on.

Regards,
-Siwei
