Multiple IRQ''s in HVM for Windows
I really need to have the ability to tie event channel port''s to
interrupts for my gplpv drivers under Windows. Is anyone working on
anything like this? Does MSI allow more than one interrupt per PCI
device?
Thanks
James

Calculating real cpu usage of Xen domains correctly!
Hi all,
With the new vm-tools we are trying to get top like capabilities going
correctly. Currently we have a program vm-list that has some of this
capability but is dependent on the cpu time given by libxc calls
(xc_get_dom_info & xc_domain_get_cpu_usage). These two functions give
you how much time (in nanoseconds, why is this not documented) the
domain has been actively used. Approaches:

[PATCH v2 0/4] XEN: fix vmx exception mistake
Changes from v1:
- Define new struct hvm_trap to represent information of trap, include
instruction length.
- Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of
wrappers around that function for existing callers, so that their parameter
lists actually *shrink*.
This series of patches fix the mistake for debug exception(#DB), overflow
exception(#OF) and INT3(#BP),
