Upgrade 7.4 to 8, not reacheable after reboot

Hello everybody! I have the same problem. But I have KVM Session on my OVH Server. I open SSH via Firewall and now I have console. The Problem is /etc/pve is empty

I have checked the syslog logs and found this:

Code: 
/etc/pve/local/pve-ssl.key: failed to load local private key (key_file or key) at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 2009.

Any ideas? :-( Hole Proxmox is offline !

This is because pve-cluster service is not starting.
Seem that ovh use cloudnit for provisiong, and it's adding "127.0.1.1 <hostname" in /etc/hosts , at each boot.

and pve-cluster need to resolve the real ip.

can you check your /etc/hosts ?

Yes, I checked yesterday and the file is the same as version 7.4 of another server I have.

So I can't find the changed file. I also added touch /etc/cloud/cloud-init.disabled to be safe

finally, before restarting post upgrade to version 8, I saved the pve folder and replaced it in rescue mode.

the only thing i see via kvm is

Booting 'Proxmox Ve GNU/Linux'

Load Linux 6.2.16-3-pve...

Loading initial ramdisk...


and nothing else..

you have replaced it ??? /etc/pve is not a real directory, it's mounted with pve-cluster service. (the real datas in /var/lib/pve-cluster/config.db , and pve-cluster expose it like a directory in /etc/pve).

also, pve-cluster will not start, if a real /etc/pve/ with files exist. (so double check that you don't have restore content in the real filesytem, /etc/pve should be empty until pve-cluster is started.)

Finally, check pve-cluster service status.

# systemctl status pve-cluster
# journalctl -u pve-cluster -f



I don't known about your kvm hanging, it's another bug, not related to pve-cluster.

Since you tried man things already. Please check if ovh installs NTP/ntpsec and replace those by chrony. There is a very annoying bug with ntpsec when network bridges are involved. I am still puzzled that this bug made it into the super stable Debian. :-/

Bingo! thanks the problem was ntp! :)

My mistake I installed in previous tests ntp and ntpdate.

This time I didn't install ntp and the server restarted perfectly.

At this point I wonder if I have to repeat the same upgrade on a production machine do I remove ntp first?

Thank you

Yes, purge ntp and ntpsec as well as systemd-timesyncd from all systems and deploy e.g. chrony.
After that you can proceed with the upgrade.

I was debugging this issue for about 6h. But it's also mentioned in the upgrade notes since I reported it.

Good morning everyone.

Over the weekend I tried to upgrade several times from 7.4 to 8 on an empty ovh test machine with this intel(r) xeon(r) cpu e3-1270 v6 @ 3.80ghz and NVME

the upgrade works without errors until the machine is rebooted.

When restarted, the machine is unreachable.

I checked through ovh rescue mode several times, also tried to downgrade the kernel with proxmox-boot-tool kernel, but without success.

I don't find particular errors in the logs through the rescue mode, but after trying and trying again I went back to 7.4

Do you think it's a kernel problem? or to the network configuration? or is the machine too old to host version 8?

Do you have any ideas?

Thank you all

Hi @milk do you install proxmox 7 from the ovh template ?
Now all work fine after upgrading?
Do you think it’s a good idea to upgrade a product environment or reinstall 8 version ?
Thanks
