Hi,

Ive upgraded to 6.6.1 and now I keep getting the following error when trying to enable VMs on the VMs tab.

Libvirt Service failed to start.

Under VM Manager settings, this is the LIBVIRT log that I have:


2018-09-27 23:31:09.873+0000: 10287: info : libvirt version: 4.6.0

Had the same error and it disappeared after a server restart. I also used the default configuration (Flash -> Syslinux configuration -> Default button). Though, the two errors and the warnings in the log are still there. Before 6.6.x had no problems starting VMs.

I am encountering the same issue and my diagnostics are attached.

Sep 30 09:09:25 nasmedia emhttpd: shcmd (5821): /usr/local/sbin/mount_image '/mnt/cache/system/' /etc/libvirt 1
Sep 30 09:09:25 nasmedia root: /mnt/cache/system/ is not a file
IMAGE_FILE="/mnt/cache/system/"

Go to settings, VM Settings and change the libvirt image to point to the actual libvirt.img file instead of just the folder

I do not have that option. My only options are whether to enable and what libvirt image to use via a dropdown. There is no place to specify the location of that image file. Even after I click Download for that image, I cannot find the file within /mnt/cache/

 

Do I really need this file if I don't plan to run Windows VMs or is the name a misnomer and has nothing to do with Windows?

If you don't plan on running any VM, then just disable the service

You need to stop the service and switch to advanced view.  But, once again if you're not running any VMs then simply disable the service altogether.

Obviously getting a Mount Error.  Any Ideas?

It might be related to you using user0 for the path, specify the correct location /mnt/cache or /mnt/diskX

Continuing to troubleshoot.  I reinstalled the OS.  Didn't help.  I think it might just be best to rebuild the Shares?

According to that, something is horribly wrong.

That's a corrupt or invalid libvirt.img, restore form a backup or create a new image.

I've deleted it, and tried to re-create it a dozen times.  I can easily rebuild my VM's.

 

How I've done it, is Settings -> VM Manager -> Libvirt storage location -> Delete Image File

 

But doing that has made no difference.

I doubt that'll work, because I nuked my nuked my shares, in an attempt to just get VM's working, and go from there.

I'm still getting "Libvirt Service failed to start." even after making all custom directories in my VM Directory custom share.  For some reason it doesn't seem to be generating the Libvirt file.  And/or when it is, its corrupted? 

 

I'm currently generating my diagnostics file.  I'll reply/edit this post when its generated, and I've uploaded it to Google Drive.

The storage location value is wrong.   It needs to include the name of the actual file, not just the folder that contains it.

Aha! It works now.  Thanks!  And thanks everyone, I'm very much new to UnRaid. :P  But so far I love it!  Can't wait until my 10TB Parity Drive comes in.

Hello, I know that this thread is a bit old but I didn't want to create a new one.

I have similar problem, doesn't even try to create a libvirt.img file and the path in Settings->VM-Manager-> is  /mnt/user/system/libvirt/libvirt.img

I cannot see anything in syslog when I enable or disable the VMs

Can anyone help?

Thank you in advance.

I have attached the diagnostics files.
