24.03 install failed in 1 out of 3

No unfortunately from what I was able to see I am not able to get a crash report after the panic.
The NIC's show as xn yes.

# lspci | grep -E -i --color 'network|ethernet'

Aha, this is good. So it's something Xen specific by the looks of it. Let's see...

stephenw10

Are you able to get the console out put leading up to the panic so we can see what was attaching?

I note that 24.03 is built on FreeBSD15 and 23.09.X is FreeBSD14 so there could be incompatibility there. What version of Xen (or XCP) are you using?

maverickws

@stephenw10 hi

I can try to either do a screen recording or halt the VM prior to boot, plug the console and get the output.
I'll get back to this.

Now I have a small question about this FreeBSD versioning:
FreeBSD 14.1 was released June 2024
FreeBSD 15 official release schedule points it to be released in December 2025

How exactly are we already on FreeBSD 15 here? How ready for production is it?

Xen version is latest

# cat /etc/os-release 
NAME="XCP-ng"
VERSION="8.2.1"
ID="xenenterprise"
ID_LIKE="centos rhel fedora"
VERSION_ID="8.2.1"
PRETTY_NAME="XCP-ng 8.2.1"
ANSI_COLOR="0;31"
HOME_URL="http://xcp-ng.org/"
BUG_REPORT_URL="https://github.com/xcp-ng/xcp"

stephenw10

For our purposes, ready. I've run it up to our devs. Let's see what they say.

Unfortunately, as I say, I don't think any of them are running Xen/XCP any longer.

stephenw10

You're not using any special packages or modules for Xen I assume?

Like xe-guest-utilities?

maverickws

@stephenw10 No I am not, quite plain install.

Mind if I was why were you questioning about the xn network interfaces? Do they have some known issues?

By default none of the VM's had guest utilities installed.
Yesterday on my last attempt I installed xe-guest-utilities to see if that would render some difference, but nothing.

stephenw10

I asked about xn because it's an unusual NIC type. There are default configs for some NICs types like em and igb and none for xn, hn, virtio etc. If you had the hypervisor configured to present e1000 NICs it might have behaved differently.

It appears to be an issue when trying to attach something Xen specific but it's not clear just from the backtrace what that is. It may be possible to simply disable it.

maverickws

Alright so I'll try to come back and present a better output of what happens previous to the crash. I'm completely unable to do it now but I'll try to do it today still.

stephenw10

Thanks, that should help a lot.

maverickws

Hello again,

I'm sorry but it was impossible for me to do this last week.

In the meanwhile I proceeded and captured the whole boot from the Boot Screen to the crash.
