Some questions about PCI-passthrough for HVM(Non-IOMMU)

Hello,
        I saw some patches about PCI-passthrough for HVM(non-IOMMU)
and I am interested in it. I want to assign my graphics card(nVidia
GeForce 7900GS) to an HVM domain (Vista) in order to run 3D-intensive
work(for example, 3D-games).
        What I want to ask is that is it really possible to pass the
graphics card to HVM domain running Vista now? That is, have anyone
ever successfully passed a modern graphics card to a Vista HVM? Since
the graphics card is a kind of complicated device. Are there any
technical problems with the passthrough of a modern graphics card?
        I have tried the direct-io.hg subtree, but I just can't boot
the Vista HVM domain with nativedom=1 option. Xen boots without any
problem with nativedom=1, nativedom_mem=1024M option(here the 1024M
memory is reserved for the HVM) and dom0_mem=800M option(I have 2G RAM
totally). But when I type xm cr vista.hvm to create the HVM
domain(note that it is bootable without the nativedom=1 option),
sometimes a disk read error occurs(as displayed on the HVM screen),
sometimes it just appear to be dead locked and sometimes it says:
"Error: Device 768(vbd) could not be connected". After the failure of
starting the HVM as nativedom, I can't even start it as a normal HVM
domain, the symptom will also be dead lock or "Error: Device 768(vbd)
could not be connected". If a disk read error occurs during the boot
of the HVM domain, the host's filesystem will appear to be
inconsistent.
        So there is surely some problems with the nativedom(Neo-1to1)
part in the current diret-io.hg subtree. The author has memtioned that
on x86-32, the memory 0-12M is mapped to 16-28M, and if any devices
DMA at 0-12M, crashes may occur. Is it possible that the dead-lock
problem and the "Device 768(vbd) could not be connected" problem
during booting are caused by the mapping?

ioemu vs no ioemu in disk device

I am a little confused about the usage of the ioemu statement in
"disk" statement
in the xen domU config file.  I have read examples both with and
without the ioemu
statement and i was wondering if there is a difference and when you need
to include the ioemu?

is there a difference between
disk = [ 'file:/xen/domU/sda1,sda1,w','phy:/dev/sda6,sda2,w']
and
disk = [ 'file:/xen/domU/sda1,ioemu:sda1,w','phy:/dev/sda6,ioemu:sda2,w']
?

TIA,
Tomoki

i can't get xen to run off of a nbd share

I have read somewhere that nbd and gnbd shared devices can be used as
a disk device under xen.

i haven't really seen any solid documentation about on how to get this done,
but when doing a search on xen and nbd,
i came across a few examples of how to get this to run
http://w3.linux-magazine.com/issue/70/Xen_3_Virtualization.pdf
disk = ['nbd:ip.address.of.server port#, sda1,w']

is this correct?
i have tried to get this to work, but i am getting this error message
Error: Device 2049 (vbd) could not be connected. Backend device not found.

i know that the nbd device is being shared properly.  I was able to
connect, and mount
it using nbd-client.

i am running xen 3.0.3 which is the packaged version in Ubuntu 7.04
feisty (ubuntu-xen-server package).

Can anyone help me?

TIA,
Tomoki

Disk performance on HVM domains

Hi list,

I converted one old FreeBSD 4.9 box to HVM domU (with AMD-V processors, 
with Intel-VT doesn't work). All works fine, but disk performance is too 
poor... about 8MB/s (in dom0 i get about 40MB/s). I did some test with 
VBD with file backed and LVM but performance stills poor.

Any advices?

Is possible to use blktap in this case? Any pointers?

If I use a SAN, network performance on HVM will be a problem?

What's about tgt?

I have one HVM old linux 2.4 domU and I can get far more disk troughtput 
than with FreeBSD, it is normal? In this case, domU is on Intel-VT Xen 
server, is Intel-VT io implementation better than AMD?

At now, I'm only testing, in the future I will need to virtualize some 
old FreeBSD servers with quite great IO demand

Many thanks,

Marc

You need to install PV (paravirtual) xen aware device drivers into FreeBSD.. 

I don't know if there is such thing..

Re: Disk performance on HVM domains

Hi Pasi,

thanks for your answer. Any pointers to do this?

Xen does't run a domainU

Hello,
I installed Xen with Opensuse 10.2 (xen packages included on this distro). I created an image file called hda.img (rwxrwxrwx and root owner) using dd, as the manual tells. I have only 256 MB of Ram so I gave 32 MB to virtual machine.
I changed xmexample1:
disk = [ 'file:/home/vale/hda.img,ioemu:hda,w' ]
cdrom = '/dev/cdrom'
boot = 'd'

I tried to comment cdrom and boot. Root device is set, by default: root = "/dev/hda1"
Xen manager list:

Re: Xen does't run a domainU

Hi,

try to change your line:

disk = [ 'file:/home/vale/hda.img,ioemu:hda,w' ]

by

disk = [ 'file:/home/vale/hda.img,ioemu:hda1,w' ]

I think that your domU is expecting a partition not a entire disk.

Cheers,

Marc

Re: Xen does't run a domainU

Sorry,

if you don't solve the problem please post the "dd" command that you 
used. In dmesg output the domU sees hda with not partition table.

Registering block device major 3
blkfront: hda: barriers enabled
hda: unknown partition table

Regards,

Marc
