Wake on Lan for Virtual Machines for 6.1+

[Mero]

Hi,

I'm new at Unraid, installed it yesterday first time (Trial). The goal is to find a solution for VMs for WoL over Internet and I found it.

Installed your VM WoL and it works really nice. Can now start my Test VM with a command line tool from any place in the world, tried it from NZ, RU, Emitrates and a few other locations. Thats what i was looking for.

THX for this App.

Hi, I tried this plugin where a Linux VM is suspended via the VM itself. Then tried waking it up using the WakeOnLAN Plugin - it worked!

 

However, I tried waking up the Linux VM from  another Linux Machine using etherwake command, but it failed. 

 

I get error:

SIOCGIFHWADDR on br0 failed: No such device

or

SIOCGIFHWADDR on eth0 failed: No such device

 

Any ideas?

 

UPDATE:

Did a wakeonlan command and it worked.

Hi everyone,

 

after enabling VLANs on the unraid machine and enabling trunk on the switchport, Wake on LAN for the VMs does not work anymore. The VMs still are on br0 and default / native VLAN ID is 1. WoL package both sent from Guacamole Docker but also sent from VLAN 1 network (192.168.1.0/24) do not wake any machine up..

 

Any ideas?

Hi guys,

I have a problem with the WOL Plugin.

It need's about 8 min to start when I boot my array. Unfortunately my unraid web log view is not working and I don't know how to provide useful Log Files to debug this behavior. 

Can someone help me there?

Best regards,

Stephan

Hello @dmacias

 

How are you? Hope you are doing well.

 

I started having issues with WOL plugin recently - it just won't start. I tried enabling/disabling from the VM Manager settings page, I tried re-installing the plugin as well as python2 in nerdpack, The daemon is not running. When trying to manually trigger start/stop scripts there are no errors thrown. When trying "python  /usr/local/emhttp/plugins/libvirtwol/scripts/libvirtwol.py br0" I am getting "GLIBC_2.33 not found, required by /usr/lib64/libpython2.7.so.1.0". I suspect an update for python in Nerdpack might have happened which triggered this (I should have probably followed the "don't touch it if aint broken" approach..., I might have accidently updated python but I can't remember if that is the case). Would you be able to advise me please?

 

Thank you.

 

 

[Valiran]

Same problem here, the script stays on DISABLE what ever i do

[ubechtle]

yeah, same here.

The Plugin don't seem to start anymore.

 

Is there any update to the Problem?
The development of the Plugin seems to be stoped.

I had the same issue and solved it that way:

 

1. Uninstall Python2 from the Nerd Pack Plugin

2. cli into your unraid

3. Download Python2 for Slackware: wget https://slackware.uk/slackware/slackware64-14.2/slackware64/d/python-2.7.11-x86_64-2.txz

4. Install Python2: upgradepkg --install-new python-2.7.11-x86_64-2.txz

 

For the last step I went to Settings, VM Manager, Advanced View enabled, Libvirt wake on lan disable, then enable again.

 

Status: Running :)

Hi,

 

Apologies if this might be a dumb question, but, does this plugin also work with an ethernet card passed through, with no MAC address defined in the XML file ?

 

 

Installed as per instructions, but /var/log/libvirt/libvirtwakeonlan.log keeps telling me: "2021-10-30 17:27:08|INFO|Didn't find a VM with MAC address b4:2e:99:30:81:fc"...

 

I've got a MacOS Monterey VM machine, configured with IntelMausi.kext with -mausiwol boot argument on OpenCore.

 

I'm sending the WOL "magic" packet via my MacBooPro, with shell command: wakeonlan  B4:2E:99:30:81:FC   

(the wakeonlan shell command was installed via "brew install wakeonlan"and I'm able to remote WOL a real laptop, with same command using its own MAC )

Thanks for this missing piece of software! 

I read the entire thread; I have only installed python2-2.7.18-x86_64-4.txz, have setup the default bridge (br1.30) in vm-manager and your pkg shows "running" - but nothing.

The machine in case is a win10-vm which had it enabled as baremetal; as vm now there's no wol-option in the adapter-configuration within windows itself, and accessing the BIOS doesn't give me a wol-option, neither machine-type i440fx-4.2 nor q35-4.2.

I'm trying to wake the machines up from the fw/pfsense directly, no dice.

 

How could I troubleshoot furhter? Does the default vm-bridge have to be on the vlan where the vms sit i.e. br1.3 or on the general interface br1?

Thanks for your time!

is there a settings menu / how do i use this software?

Go into Settings - VM Manager and enable advanced view. You should find Libvirt wake on lan. Other than on / off there are no settings. When running, VMs will wake up on magic packet.

perfect - thank you!

PSA:

 

This plugin is currently being marked as deprecated for 6.11.0.  This is because @dmacias does not appear to be active and/or maintaining the plugin anymore, and this plugin has a dependency upon Python 2 being installed from NerdPack (which will be marked as being incompatible).

 

If you've come to rely upon this plugin, then you do not have to uninstall it, but you will be doing your own package management in installing (and maintaining) Python 2 https://forums.unraid.net/topic/42320-wake-on-lan-for-virtual-machines-for-61/?do=findComment&comment=1029485

 

 

Note that if some other author decides to fork this plugin (or create an auxiliary plugin to install Python 2) then this deprecation will be reversed if/when I am notified. 

[Squid]

@dlandon has created a Python 2 plugin, so WOL is now no longer being deprecated

[J05u]

Can't make this plugin working for Guacamole

VM's not starting from any state, tried python from app store, from nerd tool, even suggestion from the post. No lack

Maybe anyone can help with?

Well it has been a while and you surely have moved on, but I had the same problem. This plugin won't work because the original developer of libvirtwol used a method to identify the vm to wake up by parsing the XML files of all the vm.

Of course a passed through NIC is just another device and not identified as a NIC with a MAC address in the XML file.

 

I considered modifying libvirtwol to make direct API call to libvirt wihtout using the XML parsing method but I know enough of dumb scripting and google to patch up something from different sources.

 

This script will listen to magic packet on the host, when receiving a magic packet to a known MAC adress it will start a virsh command to resume the VM depending of its state.

 

#!/bin/bash

# listen to udp port 9 for packets & check if it is a magic packet

while true
do
        nc-openbsd -dnlu -p 9 | stdbuf -o0 xxd -c 6 -p -l 12 | stdbuf -o0 grep -v 'ffffffffffff' | while read
        do
                mac="${REPLY:0:2}:${REPLY:2:2}:${REPLY:4:2}:${REPLY:6:2}:${REPLY:8:2}:${REPLY:10:2}"
                echo "Got triggered with MAC address $mac"

                # compare the MAC address with the magic packet
                if [ "$mac" == "<fill in with the vm mac address>" ] 
                then
                        state=$(virsh list --all|awk -v vm="vm name" '{ if ($2 == vm ) print $3 }')
                        echo "$vm in $state state"

                        # dependent of the state, resume, start or nothing
                        [ $state == "paused" ] && virsh -q resume $vm && virsh domtime --domain $vm --now
                        [ $state == "shut" ] && virsh -q start $vm
                        [ $state == "pmsuspended" ] && virsh dompmwakeup $vm
                        [ $state == "running" ] && echo Nothing to do $vm is already running
                fi
        done
done

 

You just have to replace in the mac address you want to wake up, and the "vm name".

Then configure it with the user script plugin to launch with unraid.

 

The script rely on nc-openbsd, so it has to be installed somehow on unraid.

[Drycane]

Thank you for the script. I tried to implement it on my server but to no success. I tried to install nc-openbsd via Slackware but sadly still get an error: 

nc-openbsd: error while loading shared libraries: libbsd.so.0: cannot open shared object file: No such file or directory

stdbuf: failed to run command 'xxd': No such file or directory.

 

Do you have a working way to install nc-openbsd as it is currently not available via Nerd Tools?

Thank you for the quick response. I removed the manually installed package and installed via un-get. (It was the same package anyways) 

"Currently installed package(s) by un-get:

Still get the same error:

I tried rebooting and reinstalling but still no luck. You have any other idea?

netcat-openbsd-1.219-x86_64-1cf.txz"

 

Still get the same error:

nc-openbsd: error while loading shared libraries: libbsd.so.0: cannot open shared object file: No such file or directory.

 

I tried rebooting and reinstalling but still no luck. You have any other idea?

 

My server is offline so I can't test but did you tried to install libbsd with un-get ?

It's always the obvious things. Thank you so much. I got it to work. Sadly it didn't work with the variable but after editing the startup script by adding sudo and the VM Name it now works with Guacamole. Thank you for your assistance!
