OK I changed the disk size from 1GB to 20 and now it created the file.

 

thanks

There is no need to have a file anywhere near that big.    The default size of 1GB is probably far more than is needed as all that is stored inside it is configuration information about the VM service and any VMs you create.

Ok how do I change that?  I don't see that option in the VM settings any longer. I do see the btrfs as 20GB.

 

NM figured it out

Hi Guys,

I've been using Unraid for years now, but only as a file server.  Today I've started looking at Dockers and VM's and since I'm still a noob at those, of course I've run into my first snag.  I also get the "Libvirt Service failed to start" message after enabling VM's in the VM manager.  When I look (with midnight commander) at the /mnt/user/system/libvirt directory, there is no such file as "libvirt.img".  They way I understand it, Unraid should create this file automatically when the VM's are enabled, no? 

What am I doing wrong?  (Unraid version is 6.8.0 rc6)

Thanks!

Ok.  I've now added the libvirt.img to the storage location, so it now reads "/mnt/user/system/libvirt/libvirt.img".  Still, no file is created and the error remains.  (when I ssh into the server, I still see no file). 

I've added another diagnostics file.

Go to Settings -> VM Manager and set a valid path to "Default ISO storage path:"

I'm facing a similar issue too. I've tried all the steps detailed above and unable to find a resolution. I also copied over my libvirt.img file from a backup, but still no luck.

 

Here's what I see in my libvirt logs under Settings > VM Manager

Also attaching my diagnostics. Any help would be much appreciated! I've made a lot of tweaks a lot on my VM and would hate to lose all of it :(

I'm worried I won't be able to log back into it via OpenVPN upon reboot.

Wireguard would work better in this instance, however, I'd always recommend a backup method to get in to your home network. Router based VPN can be one way, a different way would be a pc with teamviewer or some other remote access package that runs all the time.

Hello, I didn't want to create a new topic as I'm experiencing this same issue with "Libvert Service failed to start" appearing. I've rebooted, I've tried to restore the previous Libvert.img. I've made sure that it's pointing to an img file as shown here2481038_Annotation2020-03-24231308.thumb.jpg.909690bc70faab146885754339a0efce.jpg

 

I've included the diagnostics. What's strange is this happened after I downloaded the newest VirtIO Driver ISO after building a second VM.
