Re: [Xen-devel] Error restoring DomU when using GPLPV



Hi

It seems this problem is connected with gnttab, not shareinfo.
I changed some code about grant table in winpv driver (not using balloon down shinfo+gnttab method), save/restore/migration can work properly on Xen3.4 now.

What i changed is winpv driver use hypercall XENMEM_add_to_physmap to map corresponding grant tables which devices require, instead of mapping all 32 pages grant table during initialization. It seems those extra grant table mapping cause this problem.

Thanks
Annie.
