Hello, as some might have read in my previous postings, I have a Mini-OS dom0 that constructs a Mini-OS domU on x86 xen-3.0.4-testing. As the memory layout my Dom0 builds does not guarantee, that pages the DomU Mini-OS tries to use as page tables are mapped to existing memory, I changed new_pt_frame in arch/x86/mm.c in the following way: The pt_pfn is mapped R/W, then it is zeroed by a

Hello, I see a reproducable panic when doing ibping and aborting it with ^C. My setup is two machines with Mellanox Infinihost III HCAs (one Linux one FreeBSD) connected back-to-back. Details below.

Hello, this is based on the Mini-OS in the xen-3.0.4-testing.hg repository, so if any of this has been obsoleted, please say so. :) Multithreading in the Mini-OS (on x86) has some problems: a) a stack overflow overwrites the pointer to the thread''s "struct thread". Perhaps one could a segment register to point to the thread control block? b) GCC seems to use ESP as

Hello, I am hacking on a Mini-OS that is able to run as domain 0 and is able to start a guest (another Mini-OS for now). I was able to get a memory allocated to the guest and am now trying to build its pagetable and after that copy the kernel to the right places.
