Re: [Xen-devel] Restart domU failure (memory allocation issue)

[Andrii Anisov <andrii.anisov@xxxxxxxxxxxxxxx>]

This is done in kernel space. When you map the pages, privcmd will set
specific callbacks that will be use when munmap will be called (see
privcmd_close in drivers/xen/privcmd.c).
The privcmd_close function will call the hypercall to remove the foreign
page from the p2m.

We will check if it works on our site (but it looks it does not).
