[Need ideas for power on buttons for VMs]

Thanks for sharing @mtongnz. Here's my script I guess I'll share as well. This has more special haling built in for 1 GPU/multiple VM configurations to check and shutdown other VMs. In a way I like your simplified approach better but if you need to check for other running VMs you can steal from some of my functions below.

 

Use at your own risk, I'm not a coder and I don't have much bash scripting experience. Hopefully the experts on this forum can give me some feedback on what I can improve, I would really appreciate that!

 

Particularly, I'm calling this script from Home-Assistant and the only way I know how to is via SSH as the root user, would prefer a more secure solution if anybody has any suggestions.

 

Here's the User Script:

#!/bin/bash

# Script for starting stopping VMs via homeassitant
# Takes two arguments, a command (start or stop) and a VM name.
# If a start command issued, the script checks for any running VMs and shuts them down as I have a 1 GPU configuration at home
# Personally, I have this script run at array start up so it's loaded into RAM and can be called from the tmp folder by HASS, or manually
## Script includes a function to check for empty arguments or empty space and exits for the above reason (User Scripts provides an empty space as the first argument for some reason) 
comm="$1"
vm_given="$2"

#List OSX VMs for special handling
osx_vm0="MacinaboxHighSierra"

function get_vm_names {
	readarray -t vm_list < <(virsh list --all --name)
	unset vm_list[-1]
}

function get_vm_state {
	state=$(virsh domstate "$1")	
}

# This function is not currently invoked, but can be usedful for debugging
function get_vm_info {
	info=$(virsh dominfo "$1")
	echo -e "$info \n\n"
}

function check_vm_name {
	get_vm_names
	for vm in "${vm_list[@]}"
	do 
		if [[ "$vm" = "$vm_given" ]]; then
			echo "$vm_given is a valid VM name, proceding"
			return 1
		else
			:
		fi
	done
	echo "$vm_given is not a valid VM name, go home"
	exit
}

## Haven't finished writting this part yet, script will just exit at this point for OSX
## Reason for special handling is OSX doesn't shutdown when asked to by qemu
function check_if_OSX {
	if [[ "$vm_given" == "$osx_vm0" ]] || [[ "$vm_given" == "$osx_vm1" ]] || [[ "$vm_given" == "$osx_vm2" ]]; then
		echo "VM is one of listed OSX VMs, initiating special handling"
		exit
	else
		return 1
	fi
}

function start_vm {
	echo "Starting $vm_given"
	virsh start "$vm_given"
}


function shut_down_vm {
	echo -e "Sending Shutdown signal to $vm"
	virsh shutdown "$vm"
	get_vm_state "$vm"
	while [ "$state" != "shut off" ]; do
		vm_down_poll "$vm"
	done	 
}

function vm_down_poll {
	get_vm_state "$vm"	
	echo "$vm is still running"
	sleep 1
}

function loop_vms_for_shutdown {
	for vm in "${vm_list[@]}"
	do 
		get_vm_state "$vm"
		if [ "$state" == "shut off" ]
		then
			echo -e "$vm is $state"
		else
			echo -e "$vm is $state, initiaing shutdown"
			shut_down_vm "$vm"
		fi
		#Leaving this here for de-bugging purposes if needed
		#get_vm_info "$vm"
	done	
}


## Checking if arguments were supplied, otherwise exit (or shuttdown all VMs if the flag is enabled to do so)
## Arguments will be provided by HASS automation (or you can manually invoke this via command line).
## Example of how to call this script from the terminal: /tmp/user.scripts/tmpScripts/00_start_stop_VMs/script start "Ubuntu"

if [[ $# -eq 0 ]] || [[ "$1" == "" ]]; then
	if [[ shutdown_all == "enabled" ]]; then echo "No arguments supplied, shutting down all running VMs"; loop_vms_for_shutdown; else echo "No arguments provided"; fi
elif [[ "$1" == "start" ]]; then
	echo "Starting $2 VM, shutting down other running VMs first"
	check_vm_name "$2"
	loop_vms_for_shutdown
	sleep 5
	start_vm
elif [[ "$1" == "stop" ]]; then
	echo "Shutting down $2 VM"
	check_vm_name "$2"
	shut_down_vm "$2"
else
	echo "Ok I don't what you're trying to do here, $1 doesn't mean anything to me"
fi

Here's the switch configured in Home-Assistant (in configuration.yaml). Once it's an entity in HASS there are endless possibilities for adding buttons or starting/stopping VMs via automation.

switch:
  - platform: command_line
    switches:
      win10_vm:
        command_on: "ssh [email protected] '/tmp/user.scripts/tmpScripts/00_start_stop_VMs/script start \"Windows 10\"'"
        command_off: "ssh [email protected] '/tmp/user.scripts/tmpScripts/00_start_stop_VMs/script stop \"Windows 10\"'"
        command_state: "ssh [email protected] 'if [[ $(virsh domstate \"Windows 10\") == \"shut off\" ]]; then echo 1; else echo 0; fi'""
        value_template: '{{ value == "0" }}'
        friendly_name: Windows 10 VM
      ubuntu_vm:
        command_on: "ssh [email protected] '/tmp/user.scripts/tmpScripts/00_start_stop_VMs/script start \"Ubuntu\"'"
        command_off: "ssh [email protected] '/tmp/user.scripts/tmpScripts/00_start_stop_VMs/script stop \"Ubuntu\"'"
        command_state: "ssh [email protected] 'if [[ $(virsh domstate \"Ubuntu\") == \"shut off\" ]]; then echo 1; else echo 0; fi'"
        value_template: '{{ value == "0" }}'
        friendly_name: Ubuntu VM

 

[Plugin idea - Plex "Now Showing" on Dashboard]

Can't help with this project but one suggestion is to add tautulli as a custom tab, that's how I quickly check if it's ok to reboot.

[Ubuntu VM Nvidia Sound crackling]

@alturismo Create "/etc/modprobe.d/snd-hda-intel.conf" inside the VM with the following content and restart the VM.

options snd-hda-intel enable_msi=1

Crackling sound should be gone with this.

Thank you! This fixed not only audio issue but also video playback (video was pausing in sync with audio at least while testing youtube).

 

Still getting weird screen artifacts on the top right of my primary and top left of my secondary monitor, any clue as to what that could be?

 

I've got ryzen 1600x, ASUS Prime B350-PLUS mb, GTX 1060 3GB (only GPU) passed through and running Ubuntu 19.04. In the Ubuntu software updater I've enable use of the nvidia-driver-418 as Nouveau was extremely unstable (although I haven't tested that with MSI enabled).

 

Please let me know if more info would be helpful!

My request is simple, as I am a simple man: a potato.

Might go 8gb for unraid, 8gb for plex and 16 for vm

I'm by no means an expert but I've heard a few times 2GB is enough for Plex. I have 16GB total, 12GB for Win VM and I let unRAID OS manage the remaining 4GB between Plex, 5-6 other docker containers and it's own needs. Personally I find this is more than enough for my needs. Just my two cents if you're looking to save a little money on your build, you can always throw in extra sticks of RAM later if you have the slots.

[Identify source of disk access?]

You should also check out the "File Activity" plugin, it shows you a log of file access on your array

Yes, it would be double the price at least

Too bad, it's a great starting point for a backup solution!

UK only? I imagine shipping this to Florida wouldn't be cheap.

[Win10 VM graphics pass-through broke after AMD BIOS update]

Along with what @boris said above... It looks like this issue has been fixed!

Great just after I finish the roll back after a lot of anxiety lol.

 

Thank you for posting this! This worked for me on an Asus PRIME B350-PLUS downgrading BIOS from 5204 to 3806. I can pass through my GPU again to Windows 10 VM!

 

I used the link provided in the OP edit and followed the instructions, with the added step of downloading the 5204 & 3806 CAP files from Asus and extracting the body of 3806 into a rom file with UEFITool.exe to put on the flash drive.
