I do read the Blogs. They're one of the better/best blogs out there

I guess I don't (didn't) understand LTS vs updates vs upgrades.

System is airgapped so Xen Orchestra has no idea there are updates

My long-running goal is to build an edge server VM to clone repos for updates.

Ahh found it. Musta glanced over it when I skimmed through dmesg the first time.

Thank you!

[14681859.111298] BUG: unable to handle kernel NULL pointer dereference at 0000000000000000

So for the updates. How do I know when I need to install updates? I looked at releases and saw 8.2.1 was latest. Do I need to check somewhere like github?

NVM: https://koji.xcp-ng.org/builds?inherited=0&tagID=42&order=-build_id&latest=1

https://xcp-ng.org/docs/updates.html#prerequisites

FYI, system is 100% offline; so I will now subscribe to the update thread... lol
https://xcp-ng.org/forum/topic/365/updates-announcements-and-testing

Wow. Failure to read documentation. [I tried, kinda]

I am on 8.2.1; uptime 8+ months, no issues.

This is the IPMI screen output (VGA)

Recent history:
I fast copied a Win10 VM yesterday and stood it up for a user.
A tech randomed (wrong IP) into viewing the IPMI output today and pointed it out to me.

I checked:
/var/log/daemon.log
/var/log/xensource.log
/var/log/SMlog
/var/log/kern.log
dmesg

I don't see any references to a Kernel Bug in any of the logs.

Seems similar to this thread: https://xcp-ng.org/forum/topic/5174/kernel-null-pointer

@olivierlambert
Yep, thanks.
OP edited to direct link to XOA NTP documentation for those who need that.

There was no clear distinction in my mind. Apologies for any confusion caused.

@olivierlambert

So...
XOA = xen orchestra appliance
XO = xen orchestra (from sources)

I just edited my title.

Wouldn't changing NTP for both be the same? XOA just comes with a debian host OS on a virtual drive...? Who cares.

Edit: I guess maybe the XOA version comes with ntp installed?

P.S. FWIW:
The whole ecosystem is confusing and annoying to learn.

Need a single page that clearly states everything for newbies. I even forget because I don't do this constantly. Just trying to spend my morning knowledge dumping.

Set NTP in 3 places:

1. XCP-ng Hardware (Bios & IPMI)
2. XCP-ng Hypervisor (xconsole/setup/shell)
3. Edit: Xen Orchestra
   A) [from sources] (CLI only, this needs to change)
   B) XOA [Debian 11, comes with ntpd]

Steps for XO [from sources] (Xen Orchestra VM on Debian 10 Host OS):

1. Go to /etc/systemd/timesyncd.conf
2. Edit to remove '#' and add your NTP server
3. Set sudo timedatectl set-ntp true
4. Restart the service sudo systemctl restart systemd-timesyncd.service
5. Check your time sync with one of these options:
   A) systemctl status systemd-timesyncd.service
   B) timedatectl timesync-status
   C) timdatectl status

Steps for XCP-ng hypervizor host (CLI easy mode):

1. SSH into un/pw
2. Type xsconsole
3. Self explanatory (IMO)
   

Steps for XCP-ng hardware hypervisor (CLI hard mode) :

1. Edit the chrony/timeserver configuration
   sudo nano /etc/chrony.conf
2. Add any time servers you want at the end of the file, along with any options for example: server pool.ntp.org iburst
3. Restart chrony systemctl restart chronyd
4. Check it is working OK chronyc tracking

The other NTP posts make no sense.

ntpd -p does not work
It wants you to install the NTP package.
No thanks, my XO is offline.
Give me the default NTP service built-in.

I have already have XO installed in a Debian 10 built from sources using Tom's video guide.
It is offline. Not gonna put it online to add ntp service.
Installed: xen-tools, ssh keys, tmux, htop, git, cloned xen-xo repo, vim, update, upgrade, ssh.

Edited:
I misunderstood difference between XO and XOA. Post updated to reflect that.
XOA contains the NTP package. Mine did not. I'd say most building from sources won't either.
