Xen users - Jul 2013 - Cannot start Fedora 19 HVM domU

Hi,

I can start Windows 8 Enterprise and Windows 8.1 Pro HVM domUs but I 
cannot start Fedora 19 HVM domU. The domU configuration files between 
Windows 8 HVM domUs and Fedora 19 HVM domU are very similar, basically 
Fedora 19 HVM domU configuration file is copied from Windows 8 HVM domU. 
When I tried to start Fedora 19 HVM domU, the LCD monitor remains blank 
screen permanently.

I have attached Fedora 19 HVM domU configuration file and the relevant 
log files.

Please advise.

Thank you very much.

Yours sincerely,

Singapore Citizen Mr. Teo En Ming (Zhang Enming)

You forgot to mention this issue is related to VGA passthru in the subject.

Does the F19 HVM guest start if you disable gfx_passthru, and remove the GPU
from the pci = [] list,
so only passthru the USB stuff etc ?

 If you have a driver in dom0 claiming the device (other than the 
 xen-pciback
 driver), you cannot pass through that device. If you do lspci -ccc on 
 F19
 and you see the driver in use for that device being something other 
 than
 xen-pciback, that would explain why you can''t pass it through.

 Also, did you first do xl pci-assignable-add for that device? This 
 attempts
 to detach the device from it''s current driver but doesn''t
always work
 especially for GPUs. The only solution is blacklist the driver for the
 device in dom0. The downside is that you cannot run a GUI in dom0 on 
 that
 device.

Dear Gordan,

I cannot start Fedora 19 HVM domU with VGA passthrough at all. Could you 
advise me on the workaround?

As for the Intel HD Graphics (i915) driver, I have it blacklisted in 
/etc/modprobe.d/blacklist.conf already. Please refer to attached 
blacklist.conf.

Thank you very much.

Dear Gordan,

I cannot start Fedora 19 HVM domU with VGA passthrough at all. Could you 
advise me on the workaround?

As for the Intel HD Graphics (i915) driver, I have it blacklisted in 
/etc/modprobe.d/blacklist.conf already. Please refer to attached 
blacklist.conf.

Thank you very much.

 Have you confirm that no other driver is bound to the device in lspci 
 -vvv?
 Also what version of Xen are you running on each of the distros, and 
 which
 dom0 kernel?

Dear Gordan,

I have checked "lsmod | grep i915" and the command doesn''t
return
anything, which means the kernel module i915 is not loaded in dom0.

I am running Xen 4.4-unstable changeset 27238 with Linux kernel 
3.11.0-rc1 on a Ubuntu 13.04 host.

 Check lspci -vvv,find the device in the output and look for the lines 
 that say:
 Kernel driver in use:
 Kernel modules:

 The kernel driver might not be called the same thing in both kernels.

Dear Gordan,

I have checked lspci -vvv in Ubuntu 13.04 dom0 and the Kernel driver in 
use is pciback for Intel HD Graphics 4600 IGD.

As for Fedora 19 HVM domU, I don''t know because I cannot start it.

 On F19, don''t worry about starting the domU. In dom0, do lspci -vvv,
 find the Intel graphics device in the output and find what kernel
 driver / module are bound to it, if any. You can only pass through
 a PCI device that is connected to the xen pciback driver, and even
 then often only if no other driver had connected to the device first
 since that might leave it in an unknown state.

 On F19, don''t worry about starting the domU. In dom0, do lspci -vvv,
 find the Intel graphics device in the output and find what kernel
 driver / module are bound to it, if any. You can only pass through
 a PCI device that is connected to the xen pciback driver, and even
 then often only if no other driver had connected to the device first
 since that might leave it in an unknown state.

But I can only start Fedora 19 HVM domU with-out vga passthrough. I want

 You are trying to get one step ahead of what I am talking about.
 Forget domU for the moment. Before you can even begin thinking
 about the domU you have to make sure the device is available
 for assigning in dom0. If you have a driver bound to the device
 in dom0 you cannot pass it through to domU. So forget domU until
 you have actually confirmed there is no driver bound to the
 device in dom0.

 What do the following two lines say for the device in lspci -vvv
 in _dom0_ on Fedora:
 Kernel driver in use:
 Kernel modules:

 You need to do this as root, otherwise some of the output is missing.

 And the dump from the machine where you have domU working isn''t
 useful, you need to post the same lspci dump from the system

 And the dump from the machine where you have domU working isn''t

 Right, that is showing
 Kernel driver in use: pciback
 for the Intel VGA device.

 But that is expected, you said you have it working on Ubuntu.
 You now need to make sure you have the same lspci output on
 Fedora dom0 before you start the domU.

Dear Gordan,

I think you are confused. I only have *one* dom0, which is the Ubuntu 
13.04 dom0. I don''t have any other dom0.

What I am trying to do is to start Fedora 19 HVM domU in Ubuntu 13.04 
dom0, but am unable to.

Hope this clears everything.

Yours sincerely,

Dear Gordan,

I think you are confused. I only have *one* dom0, which is the Ubuntu 
13.04 dom0. I don''t have any other dom0.

What I am trying to do is to start Fedora 19 HVM domU in Ubuntu 13.04 
dom0, but am unable to.

Hope this clears everything.

Yours sincerely,

Singapore Citizen Mr. Teo En Ming (Zhang Enming)

 It does, thanks. I was under the impression you were dual booting dom0s
 and one was letting you boot domU and the other wasn''t. Apologies.
