I am still not having any luck using PCI devices, PCI passthrough,
qvm-pci command, or use with xl. Devices tab is greyed out in vm
settings windows.
qvm-pci returns: Failed to list 'pci' devices, this device type either
does not exist or you do not have access to it.
lspci returns the devices with ID like: 0000:01:00.1
In dmesg I see it load my PCI devices.
The device id like to use is a GPU, it is recognized and has nouveau
module loaded in Dom0.
When I try ~sudo xl pci-attach personal 0000:01:00.0, the response is:
libxl: error: libxl_pci.c:1634:libxl__device_pci_add: Domain 6:PCI
device 0:1:0.0 is not addignable
libxl: error: libxl_pci.c:1774:device_pci_add_done: Domain
6:libxl__device_pci_add failed for PCI device 0:1:0.0 (rc-3)
libxl: error: libxl_device.c.1450:device:addrm:aocomplete: unable to add
device
I see for one person they had to disable Intel Volume Management in Bios-
I tried this, but this option is not in my bios. I also tried disabling
USB Virt and other Intel security utils with no success.
If I do ~ sudo xl pci-assignable-list, it returns nothing.
I also tried adding, per the xen wiki, to Grub (no changes):
xen-pciback-passthrough=1 xen-pciback.permissive
~xl info | grep caps
hw_caps : ~~somehash
virt_caps : pv hvm hvm_directio pv_directio hap iommu_hap_pt_share
xen_caps : xen-3.0 hvm~~x86_64/32/32p
This is the thread that seems like my error, but I still have not found
a solution after exploring this many times over:
https://forum.qubes-os.org/t/devices-greyed-out-qvm-pci-gives-failed/9828/4
PC: Alienware X17 R2 EUFI w/ Nvidia 3080, Thunderbolt etc..
I've tried disabling just about everything in bios including the usb
virtualization with no changes yet.
Currently I can only attach USB devices. That is to any VM - all vm
settings have devices greyed out.
Any suggestions will be GREATLY appreciated!!!
