[Xen-users] use PCI VGA card on domU, and questions about USB
Hello.
I have several video cards and want to use one of them for a particular domU
http://wiki.xensource.com/xenwiki/XenFaq section 7.3 states "not at the
moment"; but, i know that this have been written years ago, and that
since that time, things changed.
I found last month a page telling how to pactch a kernel, but, i can''t
find it again.
Can you point me to the right "up to date" page, or mailing list
archive ?
ATM I am using ATI R4350 on AMD 64, Gentoo stable, with kernel XEN
2.6.34 (xen-source).
For now, what I want to know is:
- what are the patches required to use PCI devices under domU (VGA for
now, but maybe other ones later on)
- are those patches included automaticly by the gentoo package xen-source ?
- what are the symboles i must activate ?
- boot arguments to add
- HVM conf to customise
But all of this may be explained in a forum or Wiki. I just don''t find
it.
Does Qemu support PCI hotplug ? to add PCI card after boot like for USB:
usb_add host:xxxx:yyyy
*** *** ***
I have a related problem:
let say i want to plug a specific USB device to domU before i start the
machine; then i put in the conf:
usbdevice = "host:0421:04f0"
This works fine. When starting the domU, it works as expected. But, the
mouse in VNC goes wrong. The mouse normally get fixed with
usb=1
usbdevice=''tablet''
but as I add usbdevice = "host:0421:04f0",
usbdevice=''tablet'' seems
ignored. What''s wrong ? maybe i should do something like
usbdevice={''tablet'', "host:0421:04f0"} ?
Is it possible to dedicate to a domU a specific USB branch ? I mean, a
port on the dom0, or a Hub, so that, i just put this node/plug in the
HVM conf, and, all peripherals i add after starting domU will be managed
by the domU automaticly.
Is it possible to add a USB device to a domU/Qemu from a domO console ?
I mean, run a bash command or script, instead of having to hit
ctrl-alt-2 in the vnc/qemu window.
I will have the problem again if I want to add several PCI devices to my
domU:
pci=[''02:00.0'',''02:00.1'',''03:00.0'',''03:00.1'']
?
Thanks.

First, I believe it only works on HVM domUs at the moment. Also, the list of cards is fairly limited - there are some more patches making their way through development to make other cards work. Finally, this only works in Xen 4 - you must update to Xen 4 in order to use VGA pass through. If you look at the Wiki you referenced above, you can find some other pages specifically about VGA pass through.> > ATM I am using ATI R4350 on AMD 64, Gentoo stable, with kernel XEN > 2.6.34 (xen-source). > > For now, what I want to know is: > - what are the patches required to use PCI devices under domU (VGA for > now, but maybe other ones later on) > - are those patches included automaticly by the gentoo package xen-source ? > - what are the symboles i must activate ? > - boot arguments to add > - HVM conf to customise > > But all of this may be explained in a forum or Wiki.

Version 4.0 may be the first version that does not have this limitation. Since the tablet is considered a USB device, you have to choose - tablet (absolute mouse) support, or USB support - you can''t have both (at least in versions of Xen prior to 4). Even in the versions that do support multiple USB devices, you sometimes have to add the secondary ones after boot time. -Nick> > Is it possible to dedicate to a domU a specific USB branch ?

It would be nice if it were the same as disks, network interfaces, etc., where you specified something like: usb=[''dev1'', ''dev2'', ''dev3''] but I think the multiple USB support for HVM domUs has only recently been added, so I''m sure the configuration will eventually support this.

Hi, All the AMD CPUs (I guess except for the lower end Semprons, but I guess those also apply) from the last (at least 4-5 years) have virtualization caps. It is shown as "svm" in the CPU flags: http://forums.fedoraforum.org/showthread.php?t=125099 Offcourse, the BIOS must support it too. And I guess you need to either buy another mobo (see Gigabyte or Asus), or hammer your mobo producer to release a BIOS to support it. What is your mobo anyways?

RE: [Xen-users] use PCI VGA card on domU, and questions about USB
Just in case anyone thinks Ady was recommending ASUS or Gigabyte... I''m not positive, but I believe that when he says "(see Gigabyte or Asus)" he is saying see about them in your searches or in the thread he points to. I''m pretty sure you DO NOT want to have a Gigabyte or Asus board if you are trying to do PCI Passthrough. I have personal experience with ASUS and trying to get them to fix a problem with their BIOS is nearly impossible even when you have Windows and they will talk to you, if you are using Linux, forget about it. Regarding Gigabyte, I''m pretty sure they have publicly stated that they do not support hardware virtualization.

RE: [Xen-users] use PCI VGA card on domU, and questions about USB
DEMAINE, I have the same problems you have with product in general. It is quite unfortunate, and in Windows only environments, I use Gigabyte for those reasons. That said, how is the longevity of Intel boards? I know I built 18 P4s with Intel boards well over 5 years ago and the only boards that have died were definitely killed by bad power supplies. I don''t know whether or not Intel makes a board that meets your needs (I don''t know what AM3 refers to), but if they do, it might be worth considering. I know you said only one match, but I don''t know if a specific supplier had only one match or if you used the Intel MBSG (which doesn''t show all boards by any stretch of the imagination, but would certainly show Intel ones).

Re: [Xen-users] use PCI VGA card on domU, and questions about USB
Hi Dustin, That''s funny. You said you have built 18 computers sometimes in the past. And now you are saying you don''t know what AM3 refers to. My assumption is that you are either banned for using Google, or somebody built the computers for you. If you have dared to read at least my post (the last post actually, the one you have answered), you would have noticed that it''s an AMD CPU.

Re: [Xen-users] use PCI VGA card on domU, and questions about USB
Hi, Who told you this shit? Here there is: ASUS M4A88TD-V EVO/USB3 ATI 880G/SB850 http://www.asus.com/product.aspx?P_ID=umllTHNRm4IGqnbL Strangely, I had good experience with Asus and Gigabyte and bad experience with Intel (two mobos that didn''t handle the 4th GB memory hole) and HP (nx6325, their BIOS does handle 4GB, even though they advertise it too). Anyways, I guess you should look harder: http://www.ocer.net/uploadfile/200909/20090914002736615.jpg I see they have a pretty new BIOS here: http://www.gigabyte.us/Support/Motherboard/BIOS_Model.aspx?ProductID=3156&ver=#anchor_os Have you upgraded it? Good luck! PS: I am more and more worried of what it is happening today. Nobody wants to fix any issue, even if it''s their issue, even they are system administrators, even if they are paid to handle those issues. They just fill in bug reports or ask mailing lists for support. _SEARCH THE FUCKING WEB_! The solution to your troubles is right there waiting for you! So, Pierre, don''t get frustrated - you are not the only one!

RE: [Xen-users] use PCI VGA card on domU, and questions about USB
Ady, You are correct, I failed to realize you were using AMD CPUs, and I chose not to use Google. Regarding AM3, assuming it is an AMD property (and it actually occurred to me, en passant, that it was), I don''t know anything about recent AMD CPUs because I stopped paying attention to them when they went to the Athlon XP numbering system, as I don''t like marketing BS, and that''s exactly what that numbering system was (there was only one really really crappy processor that the 1700+ might even have compared to). I used AMD when they weren''t overpriced and weren''t playing the same games Cyrix and Evergreen Technologies tried to play, but that was back in the K6-2 days. On that note, the reason the 18 computers I referred to are Intel is because the person for whom I built the computers had a bad experience with Intel and would not listen to my advice to use AMD (these would have been Athlons, this was before Athlon-XP). The computers I have built since then are all Intel on account of the aforementioned reasons that lead me to abandon AMD. I know that AMD and even ATI are sometimes better choices for open-source, but ATI has been in the bloatware business longer than nVidia, so I had abandoned them as well, and as I already disliked both companies, the merge of AMD and ATI only gave me more reason to avoid them both like the plague. Anyway, I have also built several computers over the past 5 years with MSI motherboards, and not one of those has died (while an ASUS one has, this was likely due to the power supply and not the fault of ASUS), however, I don''t know that their support would be any better, and they have shortened their warranty length in the last few years. It is unfortunate that AMD doesn''t make motherboards, as I would recommend going that route if they did (the same as I mistakenly recommended Intel). Another possibility, again, that may have already been researched, would be a SuperMicro motherboard, I always cringe at the one year warranty, but I have two servers upstairs that have been running since 2002 with SuperMicro motherboards, and they may be even more likely to provide decent support, but I don''t have the experience with them to confirm or deny that. Regardless, I apologize for going off-topic and providing misguided advice.

Re: [Xen-users] use PCI VGA card on domU, and questions about USB
Hi Dustin,
I really hate when I have to talk against somebody. When someone else
talks against me I take it like "Hey, maybe he''s right.
Let''s do a small
research!". So I did.
You say that AMD is overpriced? I guess you haven''t heard about Intel?
Try building a similar system using an Intel CPU and one using AMD (both
with VT enabled!!!). You will get at least 30% higher price on the Intel
system. Why? Just because Intel is Intel! Actually, I guess it''s
because
of the letters in their names:
AMD = 3 letters
Intel = 5 letter
3/5=0.6
=> AMD should be 40% cheaper (which is somehow true)
I rest my case!
And no, I''m not an AMD freak (that geek that is using only AMD CPUs), I
am just a happy web surfer that searches the web for things he doesn''t
know. And I care about the best price over performance. Is this bad?
Let''s not forget that AMD was the first to introduce _real_ (and I
meant
_REAL_) 64bit computing, Intel was just emulating it (ever wondered why
the 64bit architecture is also called AMD64?). AMD was the first to add
graphic acceleration on CPU. Now Intel is doing it on ther Core Ix
chips. All AMD CPUs for the last 4-5 years at least have virtualization
caps, Intel is selling those for "special" prices. And still, AMD
chips
are cheaper than Intel''s.
Again, I apologize the list for the off topic, but I really hope it was
educative for the newbies. Or for those lazy enough doing a quick search
for basic stuff they don''t know.
Cheers!
