Actually that seems to be unrelated the problem (I found this out after
adding suspend evtchn support to gplpv...)

The actual error is that the call to xc_memory_op passes 33 as
nr_extents, but the return value is 32, which is an error condition. Is

XendCheckpoint:417 calls xc_domain_restore which calls

Does XENMEM_increase_reservation mean "increase reservation _by_ X" or
"increase reservation _to_ X"?
