Hello,

 

I've followed the guide here, and have successfully set up openSUSE.  However when it comes to passing through either my M1015, or the USB controller I get the following message:

 

Error starting domain: internal error: process exited while connecting to monitor: char device redirected to /dev/pts/4 (label charserial0)
qemu-system-x86_64: -device pci-assign,configfd=26,host=00:1a.0,id=hostdev0,bus=pci.0,addr=0x7: PCI region 0 at address 0xf082c000 has size 0x400, which is not a multiple of 4K.  You might experience some performance hit due to that.
qemu-system-x86_64: -device pci-assign,configfd=26,host=00:1a.0,id=hostdev0,bus=pci.0,addr=0x7: No IOMMU found.  Unable to assign device "hostdev0"

Now I am sure that VT-d and everything is enabled.  In the BIOS i have enabled both "Intel Vt-d" and "Intel Virtualization".  And in my BIOS under the CPU page it says:

 

"VT-x Supported, VT-d Supported".

 

I've done some researching and I entered the following commands to see if it was indeed enabled:

 

dmesg | grep -e DMAR -e IOMMU 
---------------------------------------------
[    0.000000] ACPI: DMAR 00000000cc17bbe8 000B0 (v01 INTEL      HSW  00000001 INTL 00000001)
[    0.011044] dmar: IOMMU 0: reg_base_addr fed90000 ver 1:0 cap c0000020660462 ecap f0101a
[    0.011048] dmar: IOMMU 1: reg_base_addr fed91000 ver 1:0 cap d2008020660462 ecap f010da
[    0.011114] IOAPIC id 2 under DRHD base  0xfed91000 IOMMU 1

 

And:

grep -E "(vmx|svm)" /proc/cpuinfo

Result: here as you can see 'vmx' shows up.

 

So I am really unsure what I am doing wrong.  I had passthrough working perfectly in XenServer, however I wanted to move to something that I had a bit more freedom with.

 

Any ideas?

 

EDIT:

Figured I should list my hardware:

 

CPU:    Intel i7 4770

MOBO: ASRock Z87 Extreme6

PCI :    M1015 (IT flashed)

PSU:    850W Corsair

RAM:  16GB (2x8G) Corsair Dominator

 

Also here is a picture of my BIOS page.

Small update, I was able to get the VM to boot by editing some files:

 

/etc/libvirt/qemu.conf
-----------------------------
clear_emulator_capabilites = 0
relaxed_acs_check = 1

 

and

 

/etc/default/grub
----------------------
GRUB_CMDLINE_LINUX_DEFAULT = "... intel_iommu=on"

grub2-mkconfig -o /boot/grub2/grub.cfg

 

However now I have a new issue, when loading up the unRAID vm with the M1015 passed through (the M1015 is attatch to a HP SAS Expander).

 

I get the following error: here

 

It seems to be the LSI code that runs at the start of every boot of my machine.  I didn't seem to have this problem when I was using XenServer... I really don't feel like going back.

 

Edit:

In case anyone cares, and I don't like when I google a question and find the exact same solved problem in a forum with no answer.

 

Turns out all I needed was some sleep, I re-flashed my M1015 to LSI9240 then back to LSI9211-IT except this time I did not flash the OptionROM.  So in the unlikely scenario that someone has my exact same problems, thats how I solved it.

 

Tower kernel: mpt2sas0: LSISAS2008: FWVersion(15.00.00.00), ChipRevision(0x03), BiosVersion(00.00.00.00)

Best thing I've ever read.
