[detect_virtual] Doesn't work with Proxmox 4.4 #9

Closed erdoking closed 8 years ago

erdoking commented 8 years ago

I testest the plugin with KVM and LXC.

KVM: [root@omd tmp]# bash detect_virtualization <<>> Manufacturer : Model : Standard PC (i440FX + PIIX, 1996) BIOSVersion :

LXC: root@mailer:/tmp# bash detect_virtualization /dev/mem: No such file or directory /dev/mem: No such file or directory /dev/mem: No such file or directory <<>> Manufacturer : Model : BIOSVersion : IsVirtualMachine : False

Hi, thank you for your feed back!

Well, LXC is a different concept of virtualization (container) and doesn't have all environment inside the container itself. Due to this, many binaries and /dev files are missing. The ideal, in this case, is make a plugin inside the Host server and detect the containers, not the opposite.

About the KVM, the output looks odd... The first output line is "<<>>" and must be "<<>>" or "<<>>".

What version of plugin are you using? Your KVM machine is Linux or Windows? If Linux, are you executing the check_mk_agent as root and the "dmidecode" is installed?

Thank you.

I don't understand what happens yesterday ...

kvm: [root@omd tmp]# bash detect_virtualization <<>> Manufacturer : Model : Standard PC (i440FX + PIIX, 1996) BIOSVersion : IsVirtualMachine : False

I think this looks a little bit better. I use 3 KVM-machines and about 30 LXC's ... i think your famous plugin isn't the best for me :(

I used the current script-version from git. Linux: CentOS Linux release 7.2.1511 (Core)

I run the script without checkmk-agent (for debugging)

For your debugging:

Hi Jonas,

I really confused by the first line of plugin, why it returned "<<>>"? Could you "cat" the detect_virtualization script, please?

Thank you.

Really sorry, i worked in /tmp and after reboot there are no script anymore ... but i find out the mistake!

It's a problem with github... if you do not check on the issue as a code remove Github the text by itself

<<<>>> as text <<<lnx_detect_virtual>>> as code ...

allangood commented 8 years ago

LXC is not a virtualization, out of scope of this plugin.
