Hello All,
This is gentle reminder about this RFC.
Sadly, Andrii Anisov has left our team. But I'm commited to continue
his work on time accounting and real time scheduling.
I do realize, that proposed patches have become moldy. I can rebase
them onto current master, if it would help.

This bug report is a follow-up to the thread "Domu windows 2012 crash"
on the xen-users list. In there we found out that it is possible to set
a value for shadow_memory that is lower than a safe minimum value.
This became apparent after XSA-304, which caused using more of this type
of memory. Havi

be undesirable for Xen to inject interrupts. When creating such forks from
