These are known regressions and are fixed by

https://lists.xenproject.org/archives/html/xen-devel/2017-01/msg03269.html

and, to some extent, by

https://lists.xenproject.org/archives/html/xen-devel/2017-02/msg00625.html

Neither have been committed yet (which reminds me that I should probably 
ping David Miller)

What I can't figure out is this failure:

http://logs.test-lab.xenproject.org/osstest/logs/105353/test-amd64-amd64-xl-qemut-debianhvm-amd64-xsm/13.ts-guest-localmigrate.log

i.e.

xc: info: Restoring domain
xc: detail: Failed allocation for dom 4: 1024 extents of order 0
xc: error: Failed to populate physmap (16 = Device or resource busy): 
Internal error
xc: error: Failed to populate pfns for batch of 1024 pages: Internal error
xc: error: Restore failed (16 = Device or resource busy): Internal error
libxl-save-helper: debug: complete r=-1: Device or resource busy
