Xcp-ng 8.3 - unable to create virtual machines

Networking & Firewalls
1

Hi Team,

I have upgraded xcp-ng from 8.2 to 8, I have also tried a fresh install of xcp-ng 8.3, I cannot create new virtual machines using xen orchestra, specifically xoa created from xenorchestrainstallerupdater.

I can create vm’s using xoa imported from the xcp-ng host.

Receiving the following error:

No object with UUID or opaque ref: OpaqueRef:8783d81d-14fd-fb7b-db44-7478e66c8b63

Sounds like a configuration issue in your pool. Might be storage or network.

Was it working before and stopped? How is the storage configured?

Update you XO to latest. Had same issue.

I had the same problem. The issue started after a clean install and right after attaching an nfs share with isos - as instructed.

I really wanted to try xcpng but with xoa install freezing mid-download (at around the 50% - 60% mark, every time) and now this, I’ve given up trying. There’s only so much time i can spare trying to fix what i expect to run out of the box. I switched back to proxmox.

@juniper, @burcak… You do realize for the best experience is to use the official XOA, right? I’m sure you would not have ran into any issue that way. The source version is for testing and bugs are to be expected. Though it is pretty stable in the source version.

It’s the official xoa that hangs mid download. Source build works fine.

I tried the 8.2 lts release hoping that would work, same thing, hangs mid download.
I tried the shell command, same thing, hangs mid download.
I tried the install xoa button on xo lite, same thing, hangs mid download

Worst part, it’s persistant. You cant stop it, you can’t cancel it, it keeps retrying on reboot.

Source build from an OS iso i downloaded to the root folder worked. But then I ran into the problem in the title of this post as soon as I linked the nfs share on my NAS for ISO to preserve root disk space.

Too many problems to even get a simple VM running, let alone getting to gfx passthrough that was my initial aim

Is that what you are using, the official xoa?

I did state above my issue was with the compiled version, no issue with official XOA.

To be clear I am not complaining, as a hypervisor my experience has been good, I personally do not like xoa’s ui, doesn’t mean it’s bad, it simply means i do not like it.

I have been testing Nutanix the past few weeks and the experience has been good so far.

Fair enough. As long as you like it and it works well for you. :slight_smile:

No. The official xoa never finishes downloading. I had to build from source, that works but then I ran into the “mount ISOs through NFS share and creating local VMs gets borked” issue.

I was asking xMaximusx :slight_smile:
