I just tried to run Xen (updated daily from unstable) with an incompatible
version of XenoLinux (I forgot to rebuild the XenoLinux tree). Dom0 just
died with no messages (non-debug build). It worked fine once I realized that
the interface version had changed, and had to rebuild xenolinux?
I know it is sort of chicken, and egg thing, but could you somehow print an
error message that says that there is a hypervisor interface version
mismatch?
Absolutely.
Christian made the very sensible suggestion that we should pass
the interface version number in to the domain in one of the
registers. It could then refuse to run or use a compatibility
mode. (hopefully the interface version would be sufficiently
close for it to be able to use HYPERVISOR_console_write to tell
someone!)
One for the todo list...
