How to detect that a server is a Proxmox 4 (LXC) host

[grobs]

Hi everyone,

In Proxmox 3 (and before), detecting that we were in a Proxmox host was easy by issuing commands like "ls /proc/vz/version" (which only reside in hosts and not in guests).

Is there a simple way like this to know if we are on a Proxmox 4 (LXC) host without using some tools like virt-what, system_profiler and other none system core commands?

Regards,
Tom

Very easy:

$ virt-what
lxc

Edit: Sorry, I should have read till the end

I don't know but maybe you would like to broadcast to with avahi?

cat /etc/avahi/services/http_proxmox.service
<?xml version="1.0" standalone='no'?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
  <name replace-wildcards="Proxmox Virtualization on %h</name> ## Name of the Bookmark
  <service>
    <type>_https._tcp</type>
    <port>8006</port>
    <txt-record>path=/</txt-record> ## Path 
  </service>
</service-group>

Then you in Webrowser like Epihany or filebrowser like dolphin this service and you can use it directly. Also available with CMDtools like "avahi-browser".

I think I misunderstood your message grobs. You want to know if you're on a proxmox HOST not inside a guest in Proxmox. The lxc was misleading for me.

There are multiple ways to check

• What if you try to check if there is a /etc/pve directory?
• Installed pve-packages
• activated pve repository
• special versions of standard packages.
• running pve processes
• As fireon already mentioned, opened 8006 port

Then you know, that you're on a Proxmox host.
