Installing Qubes 4.2.3 on Thinkpad t14 Gen5

[D2Xoi28]

I tried to install Qubes 4.2.3 on my Lenovo Thinkpad t14 Gen5 with an Ultra 7 155U.

I get the following error message at the end of the installation process at the “Setup networking” step.

['/usr/bin/qvm-start','sys-firewall'] failed:
stdout:""
stderr:"Start failed: internal error: Unable to reset PCI device 0000:00:1f.6: no FLR, PM reset or bus reset available, see/var/log/libvirt/libxl/libxl-driver.log for details"

I already tried the “Kernel latest” installation option.

You can try this post:

ThinkPad T14 (gen. 5) failes net qubes and freezes at systemd-hostnamed

You can disable qubes autostart to boot in dom0: And then in dom0 you can open sys-net Settings → Devices tab and remove the Ethernet controller from the list of PCI devices attached to this qube.

Your sys-net and other system qubes should be based on a Fedora template:

Wifi works fine with Fedora sys-net (not with Debian)

It’s expected on this hardware.
You should open settings of sys-net qube and go to the Devices tab, button at the bottom Configure strict reset for PCI devices and select your device that has problems with reset (probably network card). Or maybe sys-firewall settings, if, for some reason, you attached hardware to it instead of sys-net.
This will solve the problem almost without any secure losses.

Thank you for your answers. I have already read on the issue beforehand, but was not expecting it to be at the installation process, rather than just on the startup of sys-net.

It did work now, thank you for your answers.
