Virtual Machine clone fault (bug?)

[el1milka]

Dear Community,

I tried to clone a VM on my Truenas Scale in GUI, but I got the next message:

libvirtError

operation failed: domain '4_ubuntu' is already defined with uuid eb1f9d24-0daf-4b43-a2dc-c8e0ce5c3ba3

The VM_clone0 was created, but I cannot edit anything in it. Then I tried to delete this clone, but I got the following message.

CallError

Can somebody tell me, how to clone a VM correctly, and how to delete this false VM clone.

Thank you,

Which version of TrueNAS SCALE were you using?
Any idea whether it worked on a previous version.... or is this your first attempt?

 

[luredivino]

Same error. TrueNAS-SCALE-22.02.1

Tried to clone a vm, now getting the same error. Tried to delete the vm and now its stuck. Tried removing all devices and rebooting, but will not delete

Hi,

TrueNAS-SCALE-22.02.1
I installed it last Friday. This was my first attempt.

Hello Forum,

I can confirm the cloning error on TrueNAS-SCALE-22.02.1-MASTER-20220508-040717 nightly. After rebooting the cloned VM does appear in the list, but cannot be started:

And just to be complete, trying to delete the (incorrectly) cloned VM triggers the original cloning error again:

operation failed: domain '1_debianvm1' is already defined with uuid 058531df-b4a4-4adf-bc6e-3c98e87296e7

Perhaps the code fails to set a new uuid and/or name for the clone?

[Adnan]

same issue

 

[ctag]

I'm seeing the same error. Does anyone know if there's a bug report filed?

 

[el1milka]

I don't think so.

 

[unixland]

same issue here.

 

[unixland]

same issue here.

I filed a bug report here: https://jira.ixsystems.com/browse/NAS-116289

 

[vyper013]

Hey all... I had the same issue... I was fortunate enough that I could try deleting the "original" VM.... this then allowed me to delete the failed clone... I had just started to create a "template" VM to save me doing installs each time... for now that is what I will have to do!! lucky I don't need too many

 

[Dasos]

I can confirm I have ran into the same issue.

The "work around" was mentioned here did work. I had to delete the orginal VM (using the "forced" option) then I was able to remove the other and re-make the original attaching the orginal zvol & re-attaching the NICs with the MAC addresses I saved before hand & same devices & device order etc.

 

[stergio]

I have not cloned anything. I restart to change Bios time to match UTC time, I was curious how my VMs would react, and i got this error when I tried to run it. What gives?! Makes no sense! Wow this is beyong frustrating, it is irritating. Same issue happened when i Forced a bridge connection on the NIC.

Are you all telling me I need to delete the VM and redo thing install and config from scratch everytime I see this kind of error? That is plain crazy

Anyone else seen this before?
