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 Michael Weis Von: Weis, Michael (DWIE) 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: Oct 7 11:32:34 artemis2 journal: Interner Fehler: Kann Qemu-Befehl 'device_add' nicht ausführen: Device initialization failed.
