i installed Qubes 4.2.1 with the latest kernel on a Dell Latitude 5431.
However i cannot start any qube. The only one running is sys-usb. When trying to start any qube i get a
“Qube <whatever> failed to start internal error: Unable to reset PCI device <something> no FLR, PM reset or bus reset avaibale” Notification.
The devices Tab in the settings is greyed out for all qubes.
sudo qvm-pci says: Failed to list ‘pci’ devices, this device type either does not exist or you do not have access to it.
lspci however does show the pci devices correctly.
I tried adding
iommu_inclusive_mapping=1 as a boot parameter as indicated here but this did not help. Tried disabling virtualization as indicated here without effect.
I also tried this, but it did not work for me.
journalctl -xe i see the same error from libcirtd as shown in the notification.
How to troubleshoot/solve this?
