Evengin All,

 

I need some help please.  I have been using the VM feature in unRAID recently with great success, seeing up a Windows 10 gaming machine which has been working perfectly.

 

I have just rebooted my machine as I moved it and now the VM is missing from the dashboard and also the VM tab, all my dockers and apps seem to be working OK.

 

Both of the vdisks for the VM I created are still on the cache (which is 2x 240GB SSD's in RAID 0 for 480GB total).  Could somebody please help, I spent a lot of time setting up the VM and even longer downloading games from my Steam account!

 

Many thanks, Jon

Did you go into settings and confirm that enable VMs is set to "on"? I've had it reset on me in the past after a hard reboot, so that may be your issue. If it is set to "off" it will hide the tab in the menu...

Hi DoeBoye,

 

Thanks fro your comment, yes Enable VMs is set to 'yes' in the settings.  Also I have the VM tab so pretty sure it's enabled.

 

Thanks! Jon

Ahhh. Sorry! The way I read your original sentence was that the VM Tab is also missing!

No problem, my mistake not explaining myself properly

 

To confirm, it's the Virtual Machine I set up that is missing, it's neither on the Dashboard or under Virtual Machines in the VM tab, here it says 'no virtual machines installed'!  Cheers!

No worries! After a reread, it makes sense. I may have skimmed too quickly!

 

As far as the issue is concerned... that's a puzzler. If you ssh into unraid, what do you get when you type:

virsh list --all

 

It is a puzzler...

 

I overcame this by setting up a new VM and just directing the vdisks locations to the .img files I already had.  This seems to have done the trick although the Windows machine has a different IP address which causes a couple of headaches but nothing I can't manage.

 

Is this something I have to do each time I reboot?  Surely not.

 

I entered your command and got the following, though that shows the newly created VM i just set up (was too quick off the mark!)

Glad to hear you're back up and running!

Absolutely not. VMs don't usually disappear like that. I've rebooted what seems like dozens of times the last few weeks trying to isolate a different issue, and the only time my VMs disappeared was when the toggle to enable VMs was flipped to off for some reason. Once flipped back on, my tab reappeared, and my VM was back to normal.

 

I'm still fairly new at the whole VM thing, so maybe someone with more experience has seen this before and can comment.

 

 

Thanks DoeBoye,

 

Yeah I have rebooted in the past without any problems, and to be honest I don't reboot that often so not such a big issue. I was just a little concerned that everything had gone!  Though when I saw my .img files I was a little more relaxed.

 

This also happens sometimes with certain plugins, maybe I'm just a bit buggy.

 

Anyhow thanks for you help!! I'll see how I get on next time I need to move the server

If the VM was gone something happened to your libvirt.img, that's a system file where all VM XMLs are stored, location is on the VM manager settings.

Hi Johnnie,

 

I thought that may be the case, the libvirt.img hasn't moved from the main array ever, the location shown in the VM settings is where the .img is on the array. 

 

Very strange, that was the first thing I checked but all seems to be OK...

If it wasn't moved it may have corrupted, re-creating a new one will result in an empty VM list.

 

It's a good idea to back it up, or at least the XMLs.

Thanks Johnnie,

 

Yeah I have done that, tested and everything seems to be back to normal now. Many thanks for your help!! unRAID is awesome but

 

Jon.
