my last comment in this bts bug was about:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=29d11cfd8698038b87458ba4d1329b9da81150a5

..which is in since linux 4.13-rc2, and buster has 4.19+

Is there anyone who would wants to try reproduce the max grant frames
problem on buster with Xen 4.11 and Linux 4.19 dom0/domU?

The 'xen/grant-table: max_grant_frames reached' should show up on the
serial console. I'd like to see a test report of it actually happening.

No further adjustments/fixes will go into the Stretch Xen packages at
this stage.

Having better documentation about how to set hypervisor and guest
options to deal with all of this is still a TODO. I would really like to
get some people together to start cleaning out the whole Xen related
wiki section for Debian, and actually provide some helpful content,
including FAQ stuff like max grants, PVH, PVH+grub etc...

Whoever would want to participate in that, just reply a Yay!

Doing documentation work might seem boring, but it's write once, read
many all the way.
