plain text document attachment (hvvm.patch) OK, some explaination is needed here. The goal of lguest with paravirt ops, is to have one kernel that can be loaded both as a host and a guest. To do this, we need to map an area in virtual memory that both the host and guest share. But I don't want any conflicts with the guest. One solution is just to do a single area for boot up, and then use the

The assumption that we have an overall irqs_pending flags, and a one-to-one lguest <-> task mapping fails to hold on x86_64, where we can have multiple puppies, aka vcpus. Although ifdefs could be used, it makes the code much more unreadable, and other ports are on the way, anyway. So some sort of acessor is preferred anyway. Signed-off-by: Glauber de Oliveira Costa

lguest needs to hold a reference to its task in case it exits while another Guest is sending it I/O. Otherwise we can oops in access_process_vm->get_task_mm->task_lock().

I've been trying to get Asterisk 1.4.X running under Solaris 10 x86 with limited success. I can build Asterisk and get it started but have run in to a problem with a segmentation fault with the "help" command in the CLI. When I start Asterisk: # ./asterisk -vvvgc Asterisk 1.4.9, Copyright (C) 1999 - 2007 Digium, Inc. and others. Created by Mark Spencer <markster at

I''m sure everyone has seen the drop of VMI patches for Linux at this point, but just in case, the link is included below. I''ve read this version of the VMI spec and have made my way through most of the patches. While I wasn''t really that impressed with the first spec wrt Xen, the second version seems to be much more palatable. Specifically, the code inlining and

plain text document attachment (lguest64-debug.patch) This is just a hack patch to get output from the guest. It calls lguest_vprint from printk which is a hypercall to the host to do the printk for the guest.
