All - thank you for the feedback. It appears the issue is the embedded BCM5720, and not the other NICs. I was able to boot the installer and upgrade an xcp-ng 8.2.1 host by disabling the BCM5720 NICs in BIOS. We don't use the embedded NICs, so I'm tempted to just leave it disabled and move on for the time being. I'll experiment with the updated driver at a later time, as this may be needed by other users.
And yes, Broadcom always coming through with the quality products.
@tjkreidl Hi, thank you for the reply. I've tried both BIOS and UEFI boot methods. No change, same driver panic during boot (which then appears to hang the subsequent systemd units).
@dinhngtu Thanks for the suggestion. I'll give this a shot today.
I posted another report in the Install portion of the forum, but I suspect this may be a hardware compatibility issue at it's core. Apologies if this feels like a duplicate post, not sure where to proceed with this issue.
I attempted to install XCP-ng 8.3 on a Dell PowerEdge R660 and the installer crashes regardless of the boot option chosen (default, safe, alt kernel, etc). During boot, the system consistently hits a crash in the Broadcom bnxt_en network driver, and after that the installer hangs on different systemd unit jobs. Ultimately the boot process hangs and the installer never proceeds.
Is this hardware expected to be compatible with XCP-ng 8.3?

I am currently setting up a server using xcp-ng and XOA. I have used XenCenter and xcp-Center for a long time and have come to rely on the Networking section of the Host panel, under IP Address Configuration. I regularly configure extra IPs on specific interfaces, but can't seem to find this functionality under XOA.
I would like to move to XOA for all provisioning from end-to-end (CLI is fine as well, just no more xcp-center).
I saw a similar request exists from 2 years ago, but no resolution:
https://xcp-ng.org/forum/topic/3837/how-to-set-ip-for-storage-on-each-server
I can see these IP addresses on other hosts that were configured with xcp-center, but I cannot add new ones.
Thanks very much for any guidance!
+1 also curious how this might impact xcp-ng going forward.
I have a set of hosts on kernel-4.19.19-6.0.11.1.xcpng8.1 and I believe I'm hitting this as well. The OOM seems to kill openvswitch, which takes the host offline and in most cases, the VMs as well.
