Questions about direct hardware access, DMA, etc
Hi folks, this is my first post to the mailing list. I have a general
question about the state of various efforts aimed at granting a domU
physical access to a hardware device like a NIC, graphics card, etc.
I generally understand the challenges this poses to a hypervisor in
terms of interrupts and DMA. I am specifically wondering about what
options are available when running non-Paravirtualized

[Patch] Make memory hole for PCI Express bigger and prevent roll-over
Keir,
Here''s a first patch to address the issue with rolling over to
guest-physical address 0x00000000 when assigning address regions to
PCI BARs during HVM boot. For now, this:
- Makes the hole bigger: 0xC0000000-0xF5000000. This might be
overkill...but it should only matter for 32-bit guest OSes assigned
more than 3GB of RAM.
- Prevents addresses from above 0xF50000000 from

Using VT-D to grant a Windows DomU access to a PCI Express graphics card?
I''ve also been trying to get hardware-accelerate Direct3D to work in a
(Windows) DomU via VT-D. I''ve got a PCI NIC passing through fine, but
not a graphics carrd. The points below describe where I''m at and what
is happening. I''d appreciate any help anyone could offer, and also I
have these specific questions:
Is PCI Express supported by VT-D and/or

virsh vs. xm, and questions about different distributions of Xen
Virsh (the xm-like tool that comes with libvirt) uses .xml files to
define and describe DomUs. xm uses simple configuration files to
define and describe DomUs. Is there any interoperability between
these two? Like can virsh take an xm DomU config file, or vice versa?
Or is there a tool to translate between them?
On a somewhat related note, can anyone tell me at a high level what is
different
