similar to: [RFC/PATCH LGUEST X86_64 03/13] lguest64 core

plain text document attachment (lguest64-debug-utils.patch) This patch contains some nice features used to debug the lguest64 guest. It has a way to print page tables for either the host or the guest. It incorporates kallsyms, and can do a nice back trace of a guest when it crashes. The guest needs kallsyms obviously compiled in. Note: This code needs to be fixed to be more secure! Implements

Hi all! Lately, Glauber and I have been working on getting both paravirt_ops and lguest running on the x86_64. I already pushed the x86_64 patches and as promised, I'm pushing now the lguest64 patches. This patches are greatly influenced by Rusty Russell, and we tried to stay somewhat consistent with his work on the i386. But there are some major differences that we had to over come.

plain text document attachment (lguest64-device.patch) We started working a little bit on the devices for lguest64. This is still very much a work-in-progress and needs much more work.

Hi, this version requires that host and guest have the same PAE status. NX cap is not offered to the guest, yet.

Hi, For some days I have been looking for the bug that causes an easily reproducible oops in the guest when I apply my PAE support _draft_ patch (appended at the end of this mail) to lguest. This is the oops: Setting kernel variables...done. Will now mount local filesystems:. Will now activate swapfile swap:done. Cleaning /tmp... [ 84.749676] BUG: unable to handle kernel NULL pointer

This is taken from the work I did on lguest64. When killing a guest, we read the guest stack to do a nice back trace of the guest and send it via printk to the host. So instead of just getting an error message from the lguest launcher of: lguest: bad read address 537012178 len 1 I also get in my dmesg: called from [<c0405f30>] show_trace_log_lvl+0x1a/0x2f [<c04069aa>]

Christoph Hellwig said runs sparse: 1) page_tables.c unnecessary initialization 2) Change prototype of run_lguest and do cast in caller instead (when we add __user to cast, it runs over another line). Al Viro pointed out the ugly cast in push_lguest_stack(): 3) Stick with unsigned long for arg, removes 4 casts in total. Most importantly, I now realize that Christoph's incorrect ranting
