VGA/PCI Passthrough of Secondary Graphics Adapter
Aloha!
Concisely, I''ve been trying for several days to get VGA/PCI passthrough
working. Regarding VGA vs PCI passthrough, I''m not entirely certain of the
difference? Does Xen perform a different set of operations when passing
through a VGA card versus any PCIe card? I''ve read the wiki and it seems
the answer is "yes;" however, when passing through a

Assistance in tracking a kernel/nouveau error
Greetings,
I am resending this as it doesn't appear in the archives and no one
responded...maybe it got routed to /dev/null or something :-)
I have asked this question the Scientific Linux mailing list (a few
months ago) and got the suggestion I talk to the kernel guys. I pinged a
kernel guy I know, and his suggestion was to ask the Nouveau list. So
here I am. :-)

Setting up a pci passthrough device
I have been investigating pci pass-through for virtualized
guests and the documentation I have found seems to me to
lack a certain consistency in its example. This may be
due to my not understanding what it is trying to inform
me.
What I wish to do is to configure a pci multi-port serial
i/o card for use by a single virtual host.
I start by running lspci -v on the host to identify the

Audio weirdness on CentOS 6.2 with flash?
Hi List,
I have an ASUS G73S laptop with our favorite OS installed and all
up-to-date.
Sound has always "just worked"
When I use the Preferences>Sound app I can setup the hardware, input,
output and was overall very impressed.
One can check each speaker and the laptop has a front left and right and
also has a bass speaker which seems to be connected to the left rear.

Recommended Best way to Upgrade/Update Xen
This might be a silly question for most, but since Xen is ever so
changing with regular changesets and updates, what is the "best
practice" way to upgrade / update or even downgrade Xen?
1.) Is it by booting into regular Linux Kernel without Xen, do a
complete uninstall of the old Xen, than install the newly compiled Xen?
2.) Is it by booting into regular Linux Kernel without Xen,

Which QEMU device-model to use for Windows HVM guests???
Just wondering about which QEMU version to use. Looking in the xl.cfg
MAN page, you can choose from "qemu-xen-traditional" or "qemu-xen",
however i have seen a third one "qemu-dm" WHICH is not listed in the
xl.cfg man page.
I know the "qemu-xen-traditional" device-model is the default one as it
is more stable, compatible and so forth. The

Hello, guys.
First apologize my flaws, I am not a native English speaker and thus am

This looks like a deadlock of some sort. I don't think your

PCI/VGA passthrough and function level reset (FLR)
I''m wondering if FLR really must be supported by the PCI card for
PCI/VGA passthrough to work or if it will work anyway. I have read in
the VTdHowTo that trying to pass through hardware without the FLR
feature will result in an error. At the same time I read on a pdf
document on the VMWare website

[PATCH] Improve the current FLR logic
Hi, all,
The attached patches try to improve the current FLR logic.
The idea is: removing the FLR logic from hypervisor and adding the
improved logic in Control Panel.
The current FLR logic in hypervisor has some issues: 1) Dstate
transition is not guaranteed to properly clear the device state; 2) the
current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND

Status of FLR in Xen 4.4
Hi everyone,
I would like to ask what the current status of FLR, or better of FLR
emulation is in latest Xen and if we can expect better support in the
future.
I''m asking because with xl (latest build and traditional qemu, not
upstream), I always had problems with rebooting domUs which have vga cards
passed through to them, because appearently they don''t get reinitialized

Strange PCI Passthrough problem
I have successfully passed through a video card, network card,
USB mouse, and USB keyboard to a MS Vista guest. That

or PCI USB hub, but I am running into a strange problem.
When I plug the PCI audio (or USB card) to the motherboard.
It makes it so that the PCI video card is no longer an

[Xen-users] Why the need for "-f" with XL in Xen 4.2 rev-25467
Just out of annoyance more than curiosity, but ever since I started

create <domu_config_file>", or "sudo xl reboot", or "sudo xl destroy",
it always gives me this message:

Now it comes downgrade or install two R versions under Linux
R-sig-Debian help,
Yesterday I sought help regarding R upgrading from R-2.8.1 to R-2.9.1.
I must thank specially Dirk for his helpful advice.
But now I am facing a dilemma. I want to install a package called FLR which
works under R-2.8.1. So my question is whether I can keep the latest release (R-2.9.1)
and also install R-2.8.1 (and if feasible how.)
Alternatively I could uninstall R-2.9.1 and
