At the example of this, I find:

Err:1 http://ftp.debian.org/debian buster/main amd64 genisoimage amd64 
9:1.1.11-3+b2
  Could not connect to cache:3143 (172.16.148.6). - connect (113: No route to 
host)

  Could not connect to cache:3143 (172.16.148.6). - connect (113: No route to

to connect to cache:3143:
E: Unable to fetch some archives, maybe run apt-get update or try with 
--fix-missing?

Network issue (hopefully just a transient one)?

>     x86/P2M: deal with partial success of p2m_set_entry()
>     
>     M2P and PoD stats need to remain in sync with P2M; if an update succeeds
>     only partially, respective adjustments need to be made. If updates get
>     made before the call, they may also need undoing upon complete failure
>     (i.e. including the single-page case).
>     
>     Log-dirty state would better also be kept in sync.
>     
>     Note that the change to set_typed_p2m_entry() may not be strictly
>     necessary (due to the order restriction enforced near the top of the
>     function), but is being kept here to be on the safe side.

>     Users of XENMEM_decrease_reservation and XENMEM_populate_physmap aren't
>     required to pass in order-aligned GFN values. (While I consider this
>     bogus, I don't think we can fix this there, as that might break existing
>     code, e.g Linux'es swiotlb, which - while affecting PV only - until

>     allocation.) Only non-PoD code paths (guest_physmap_{add,remove}_page(),

>     implemented inefficiently, handling every 4k page separately).

>     Introduce wrappers taking care of splitting the incoming request into
>     aligned chunks, without putting much effort in trying to determine the
>     largest possible chunk at every iteration.
>     
>     Also "handle" p2m_set_entry() failure for non-order-0 requests by
>     crashing the domain in one more place. Alongside putting a log message
>     there, also add one to the other similar path.
>     
>     Note regarding locking: This is left in the actual worker functions on
>     the assumption that callers aren't guaranteed atomicity wrt acting on
>     multiple pages at a time. For mis-aligned GFNs gfn_lock() wouldn't have
>     locked the correct GFN range anyway, if it didn't simply resolve to
>     p2m_lock(), and for well-behaved callers there continues to be only a
>     single iteration, i.e. behavior is unchanged for them. (FTAOD pulling
>     out just pod_lock() into p2m_pod_decrease_reservation() would result in
>     a lock order violation.)
