CBT Error when powering on VM

[rustylh]

Trying with XOA Lite. VM Acts like it's starting then just stops.

The VM is now starting to the Alma boot page, goes past that then shows Paused. Then just goes back to a powered off state.

[olivierlambert]

Are you sure the VM operating system isn't crashing? Are you seeing anything during boot phase?

[rustylh]

It acts like it is starting normally and goes to the Kernel version selection for Alma, starts to boot then shows paused, then goes back to powered off state and shows the attached.

[rustylh]

XOA Just shows it starting

[rustylh]

Does this help?

@rustylh Can you try another kernel version or a safe mode if available in the Grub menu of your VM? It seems the OS cannot boot anymore, for whatever reason happened inside the VM.

[rustylh]

I tried the second Kernel. I can try safe from Grub. I am not familiar with that, but I will try.

[rustylh]

Same result

[olivierlambert]

To me, you have an issue inside your OS. You can try to mount the disk of this VM in another VM and try to check what's going on, maybe do a file system check or something.

[rustylh]

Ok, thank you for looking. Is there anything in my previous screen shots that sticks out? Something else I can try?

[olivierlambert]

I would check inside the OS that cannot boot anymore, running an fsck

That's what I would do

[rustylh]

Ok, this is weird. I just created a new VM with new name. It is booting and hung at the same message.
vdb vdb-5696: 19 xenbu_dev_prob on device/vdb/5696

Not sure what to think.

[olivierlambert]

That's an OS issue, as I said. You need to mount it in another VM as an extra drive, or use a LiveCD to explore the filesystem

[rustylh]

I understand. However, this is a bran new VM I just created with a new name.

[AtaxyaNetwork]

@rustylh How are you creating your VM ?

[rustylh]

Center. I'm trying to get away from that and go with XO

[rustylh]

Can I do everything in XOA Lite that I can in XCP-NG Center?
