Hello folks.
My PVE instance was up for 19 days, during this time I did:
  • I used cloud init the first time a couple days ago and pretty much followed this tutorial.
  • i created like 3 vms with cloud init, including one with qm clone 9000 191 --name tpy2 notice the name of the vm - got hostname of pve instance now
  • updates and haven't rebooted yet
Whats going on now - first things that i noticed:
  • pve boots, has a new hostname.. its now root@tpy2 instead of root@pve
  • ssh keys are different ( i think the one from tpy2)
  • username root and the password for my pve stayed the same
  • pct list for my lxc containers response with "Connection refused"
    ipcc_send_rec[1] failed: Connection refused
    ipcc_send_rec[2] failed: Connection refused
    ipcc_send_rec[3] failed: Connection refused
    Unable to load access control list: Connection refused
  • same for qm list
  • cannot access Web UI
  • folder /etc/pve is empty
  • one zfs pool where I got problems mounting it at boot time, doesnt come up as unmounted when looking at zfs list (as it did before, so I could manually mount it by zfs mount -a)
It is as if proxmox booted into that tpy2 vm but mixed in its own environment (commands etc) as well..
What the hell is going on? What can I do? Anyone has seen this occurrence?

Thanks in advance!

it seems you installed cloud init on the host? if yes, remove it and revert all config changes it did (network/hosts) etc. ..

I think you are correct, I ran
apt-get install cloud-init
on the host.
I uninstalled it via
apt purge install cloud-init

and did a reboot.

Same condition as before.

I didn't ran any other host changing command regarding the network/ hosts manually. Did cloud init change something, that I have to revert ?

Edit:
removed
rm -rf /var/lib/cloud/
changed
/etc/hostname
changed tpy2 -> pve
pve
/etc/hosts
deleted line 127.0.0.1 tpy2
I did never touch the hosts file on my host, I don't know its initial state. Sadly I dont have a backup of this file.
# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist

# a.) make changes to the master file in /etc/cloud/templates/hosts.debian.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
# /etc/cloud/cloud.cfg or cloud-config from user-data

127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts

seems normal/ unharmed

I still cannot access pct/ qm, nor the web UI

EDIT2:
Just saw
root@pve:~# dpkg -l | grep cloud
ii cloud-guest-utils 0.29-1 all cloud guest utilities
so I did
root@pve:~# sudo apt-get purge --auto-remove cloud-guest-utils

I guess the hostsfile is not complete.

after reboot condition has not changed

EDIT3:
sorry this is getting long.
added this in /etc/hosts
127.0.0.1 localhost.leserver localhost
172.16.1.100 pve.proxmox.com pve pvelocalhost

Problem solved.

yes, thats the point of cloud init

it seems you are missing the 'ip hostname' entry in /etc/hosts

there should be line probably like

172.16.1.100 pve.fqdn pve

where 'pve.fqdn' is the fully qualified domain name (e.g. pve.foo.com) (this is what was chosen in the installer for the domain name)

I saw on some post the usage of
172.16.1.100 pve.proxmox.com pve pvelocalhost
eventhough my fqdn i set at the installation was "leserver", it worked. I will change it though.
Thank you Dominik
