Hello all!

Xenbus patch seems to have solved the xend/xm problem. Could please
apply it Keir?

Patch message:
Implements XenBus transactions in MiniOS.

It looks like this patch only updates MiniOS - does this mean that
broken (or malicious...) guests can still hang the control server, or
has that been fixed independently?

Further tests revealed that the problem has not gone away completely (although it seems to be happening more sporadically).

If Mini-OS does not initialise XenBus (if you remove xenbus_init() call from kernel.c) the problem will not appear at all. So far I have not been able to pinpoint the root cause of the problem though. Maybe somebody more familiar with XenStore will be able to help.

The patch certainly does not break anything though (this is mostly for Keir's attention).

I'll get back to you if I find anything more.
