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

[Andrii Anisov <andrii.anisov@xxxxxxxxxxxxxxx>]

It seems that unmap will be done at the end of xc_dom_boot_image (see
xc_dom_unmap_all).
The latter function will go through the list of all mappings and close
it one by one.
You can add a print in xc_dom_unmap_one (tools/libxc/xc_dom_core.c) and
check if you have the same number of print with xc_dom_pfn_to_ptr_retcount.

As I see xc_dom_unmap_all ends with munmap(), what actually unmaps pages from process virtual memory space. But I have doubts if it is aware about cross domain mapping and cares about it.
