This will do the verification, and finds many errors:

2021-02-10 02:37:03 MST [2149] xc: error: verify pfn 0xfda9 failed (type 0): 
Internal error

As Andrew said elsewhere, something writes into the memory of the idle, but 
suspended domU. Likely the netback, since it can not know that the domU will 
never come back.

No idea if verify_frames would have ways to figure out what purpose a given pfn 
really has.
