One VM forcibly restarts
-
Hi,
I am a new user of XCP-ng and so far, my experience has been great! I have been a long-time user of XenServer but stopped updating the hypervisor when Citrix crippled the free version. I randomly came across XCP-ng and I couldn’t believe my eyes, how I hadn’t come across this sooner!
My server is for personal use at home, with a few VM’s and host a website for free for a local youth charity. It is great to once again, have a hypervisor that is current and not a gigantic back-door!
Anyway, to the problem… today, I experienced a strange problem that I can’t seem to find a reason for and I ended up deleting the problematic VM before thinking of trying to capture some logs beforehand. I had a Windows 10 VM that the hypervisor was forcing a reboot of. When using it, the console would just go blank and then a few seconds later, the VM would turn back on and start booting back into Windows. This kept repeating, where it would only stay on for a minute or two?
I even tried attaching the virtual disk from the VM, to another VM and it didn’t power-cycle. I then created a new virtual disk on the problematic VM and every time I tried to boot it into the Windows ISO, it would force restart to the point I couldn’t even get it to boot from the ISO any more. I ended up deleting the VM, I know I should have tried to get the logs beforehand, but I just wondered if anybody may have an idea of what might have been the cause of this?
I am just a little paranoid that hardware is starting to fail, hopefully not.
One last thing, I have been trialling Xen Orchestra and it’s fantastic! Such an improvement from Citrix XenCenter. I was wondering if there is a licence option available for people who only use the product for personal use / hosting for charities?I realise this is quite a lengthy post, apologies haha!

Hello @richiebyte
Glad you finally found XCP-ng
And wait to discover you can use XO from the sources with all XO features for free, as it's fully Open Source: https://xen-orchestra.com/docs/installation.html#from-the-sourcesXOA (the turnkey virtual machine/appliance) is meant to be sold to companies. As a home labber, it's fine to use the version from the sources
edit: to answer your original question, it's hard to tell, do you still have the issue with a fresh new VM running on Windows?

That's perfect, thank you, I'll check that out!
In regards to the problematic VM, it only happened to this single VM. With a new fresh VM, with the virtual disk from the problematic VM, seems to be working. I just found it really strange as I created a new VM using the exact same settings, with the original virtual disk. The only thing I did yesterday to this VM was install Citrix' guest tools 9.3.1 (I have this installed on other VM's and they're working OK, although the other VM's are Windows Server 2019/2022). That's the only change that I had made.

So since you installed the Citrix tools it started to reboot, right?

On this one VM yeah, all other VM's have been fine with the Citrix tools. I am not sure if the tools change anything on the VM level once installed, as the problem did continue after attaching a fresh blank virtual disk to the problem VM.
