Re: [libvirt-users] passthrough of PCI-device

Good morning,

there is a typo in my description;
the line
     <address domain='0x0' bus='0x1' slot='0x00'
function='0x0'/>
should be
     <address domain='0x0' bus='0x2' slot='0x00'
function='0x0'/>
That was correct in my xml-file.

Isn't there anybody how can help me with that?


Regards

Betreff: passthrough of PCI-device

Hello,

I try to passthrough a PCI-card to a VM named  testvm
I want to do that with an xml-file named hga.xml including the following
content:

<hostdev mode='subsystem' type='pci'
managed='yes'>
  <source>
     <address domain='0x0' bus='0x1' slot='0x00'
function='0x0'/>
  </source>
</hostdev>

When I execute
virsh attach-device testvm hga.xml
I get the following error:
Fehler: Fehler beim Anhängen des Geräts von hga.xml
(error: error while attaching device from hga.xml)
Fehler: Interner Fehler: Kann Qemu-Befehl 'device_add' nicht ausführen:
Device initialization failed.
(error: internal error: cannot execute 'device_add':

In the syslog of the host I get the following errors:

Dear Michael,

Did you activate the Intel IO MMU (or its equivalent for AMD)?
Also, did you load the pci_stub module for Linux? It is mandatory (it
will replace current driver for your passed through hardware).

Hi Pierre,

thanks for your reply.

I am using kernel 3.10.0-123.8.1.el7.x86_64.
The kernel modul used after nodedev-detach is vfio-pci
