@Nornode hey, nope I did not. I ended up moving my infrastructure to Proxmox.

Honestly this is no fault of XCP-ng and XCP-ng suits my hardware / setup a lot better, but it was either that or I had two servers that needed to be bare metal.

jjgg

Definitely frustrating and no fault of xcp-ng - I have a lot of spare cpu cycles so it isn't majorly impacting me that I know of. I'm still available to test fixes though.

Looks like most of the Proxmox users have got this working in an LXC container by installing the drivers on the host itself and passing through the actual Apex devices. Not a route that's applicable to us but just a datapoint.

jjgg

Booted into fallback and put things back the way they were. Happy to keep testing if there's additional bits to test.

jjgg

Ok so testing setup.

Downloaded xen.gz, renamed to xenept.gz and put into /boot:

Updated grub.cfg to point to that file:

Rebooted host.

Got to the grub screen, let it load as normal, as soon as it disappeared (so it had made the default selection) the server rebooted.

I ended up just placing xen.gz in /boot and removing the symbolic link to the original and attempting, no difference.

Of note, messing with kernels / grub is not something I've got experience with. I may have made a mistake / need things explained in a bit more detail if I'm potentially misunderstood some instructions above.

jjgg

@andSmv thanks. Completely understand this appears more of a hardware issue here, but happy to test anything. The host that these cards are installed in isn't running critical infrastructure and can be rebooted relatively easily.

@exime your initial post was a top Google result, was still helpful! Thanks.

@andSmv

xl dmesg from the host in question. Note the last set prefixed with 739760 appeared just after I attempted to install the drivers, the depmod process was just running, it turns off before dpkg finishes. I've just included the whole set as I suspect this is from several different attempts.

Additional note, I actually have two Coral PCI devices installed. For the final test I only passed one through to the VM.

@andSmv I'm pretty sure I'm having the same problem as @exime except I'm getting the VM just cold turning off.
