Re: Dom0 PAE panic when starting xend

jym: Does your save/restore/migration work have some fixes related to

If yes, can you commit them, please ?

I'm actively investigating this matter, as I have similar problems with the page fault handler during a migration with an updated current, on a call to xc_map_foreign_batch().

During the live save, vaddr 0xbba9c000 <> 0xbba9d000 access trigger a page fault in dom0, and it keeps calling privpgop_fault in a loop, which leads to a hang.

These faults happen when dom0 maps the p2m translation tables. I am looking at it.
