Hi.
I'm using Proxmox VE 3.4 with qemu-server 3.3, and I'm trying to pass
two PCI-Express AudioScience soundcards to a KVM virtual machine.
The soundcards are the following:
ve2:/# lspci
03:00.0 PCI bridge: Texas Instruments XIO2000(A)/XIO2200A PCI
Express-to-PCI Bridge (rev 03)
04:00.0 Multimedia audio controller: Texas Instruments TMS320C6414
TMS320C6415 TMS320C6416
05:00.0 PCI bridge: Texas Instruments XIO2000(A)/XIO2200A PCI
Express-to-PCI Bridge (rev 03)
06:00.0 Multimedia audio controller: Texas Instruments TMS320C6414
TMS320C6415 TMS320C6416
and I configured the virtual machine in this way:
machine: q35
hostpci0: 03:00.0
hostpci1: 04:00.0
hostpci2: 05:00.0
hostpci3: 06:00.0
But when I try to start the virtual machine I get the following error:
ve2:/# qm start 202
kvm: -device pci-assign,host=03:00.0,id=hostpci0,bus=pci.0,addr=0x10:
Device assignment only supports endpoint assignment, device type 7
kvm: -device pci-assign,host=03:00.0,id=hostpci0,bus=pci.0,addr=0x10:
Device initialization failed.
kvm: -device pci-assign,host=03:00.0,id=hostpci0,bus=pci.0,addr=0x10:
Device 'kvm-pci-assign' could not be initialized
I realized that I cannot pass the PCI bridge, so the VM starts passing
only 04:00.0 and 06:00.0 devices.
But Alsa on the virtual machine cannot recognise the soundcards, so
I'm thinking that the problem could be that I'm not passing the PCI
bridge.
Could you help me please?
Thank you very much!
Bye
