Single GPU passthrough VM won't start [SOLVED]

I just tried to setup a GPU passthrough VM using virt-manager, but when I attempt to start the VM, nothing happens and about half a minute later this error appears

 Error starting domain: Cannot recv data: Connection reset by peer

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 65, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 101, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn
    ret = fn(self, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/domain.py", line 1329, in startup
    self._backend.create()
  File "/usr/lib/python3.9/site-packages/libvirt.py", line 1353, in create
    raise libvirtError('virDomainCreate() failed')
libvirt.libvirtError: Cannot recv data: Connection reset by peer

There was nothing on the qemu logs but after I turned on libvirt logging I found this

I have looked all over and cannot find anything about this error. Thanks in advance.

Those script files don't seem to exist in archlinux repos , although (atleast) the first does appear in arch wiki .
Are you trying to follow https://wiki.archlinux.org/title/Intel_GVT-g ?

I was trying to follow this guide: https://github.com/joeknock90/Single-GPU-Passthrough

Re: Single GPU passthrough VM won't start [SOLVED]

That guide does look ok, Maybegus .

They do not mention one minor detail though : scripts need to have the executable bit set to be run.
Incase you don't know how to do that , check https://wiki.archlinux.org/title/Help:R … executable

Re: Single GPU passthrough VM won't start [SOLVED]

I thought I did this step but apparently I didn't. Thanks!
(for anyone in the future i did

sudo chmod +x /etc/libvirt/hooks/qemu

)
