Use config VM:

It didn't yield result.

Hi!

Thanks for your answer!

1. Version Xen:
(XEN) Xen version 4.4.1-pre (gcc (Debian 4.8.3-2) 4.8.3) debug=n Tue Jun 10 08:25:03 CDT 2014

2. Kernel:

Linux hv2 3.14-1-amd64 #1 SMP Debian 3.14.4-1 (2014-05-13) x86_64 GNU/Linux

Variant using :

A). Config file my VM:

device_model_version = "qemu-xen-traditional"
device_model_override = "/usr/local/lib/xen/bin/qemu-dm"

A.1) Trouble in VM(use conf file VM 3):
VM is not starting!

register_real_device: Real physical device 03:00.0 registered successfuly!
IRQ type = INTx
pt_pci_write_config: [00:05:0] Warning: Guest attempt to set address to unused Base Address Register. [Offset:14h][Length:4]
pt_pci_write_config: Internal error: Invalid write emulation return value[-1]. I/O emulator exit.

OR

B) Config my VM:

device_model_version = "qemu-xen"

B.1)
My VM is starting! %) But It have a problem...
Please, look at attach file.

qemu-dm file is have size 5.1Mb. Are you sure attaching file in here?

nvidia card into VM: Region 1: Memory at 100000000 (64-bit, prefetchable) [size=4G]
nvidia card into DOM0: Region 1: Memory at 5800000000 (64-bit, prefetchable) [size=16G]

Why? Where 12G was lost?

I try use memory for VM == 1G... there's no difference at all

Could you attach your qemu-dm files, the lspci -vvv from dom0 and
from the guest.

Does it work if you use less memory? Say mem=2G?

This is output message of command xl create:
dmesg:

It is All.

Maybe I will try use this parameter in Xen 4.3?

Yes, I think so. I have a sneaky suspicion that qemu cannot handle
BARs over a certain size. Have you tried with
device_model_version = "qemu-xen"
instead of qemu-xen-traditional ?

I can give you logs!

no, no.
With 4.3 is bad work! With 4.4 is do not starting.
I see into lspci: BAR1 is not possible assignment. With 4.3 can not
maping BAR1.
Thanks!

Xen 4.3 start this VM, but Xen 4.4 is not starting VM.
So you are saying that this works fine with 4.3 but breaks with 4.4?
