I installed a new vm with win10 pro, after the installation I installed the XCP-NG tools.

After reboot, the tools were functioning normally.

Very well, this means the XCP-NG tools work

Then I went to the other vm, the one where the vm tools stopped working and tried the following:

1. Unistall the XCP-NG tools.

2. Run the "XCP-ng-Windows-Guest-Tools-Cleaner_alpha" I found here in the forum (https://github.com/xcp-ng/xcp/issues/152). With this tools I managed to identify and manually delete some "left behind" file in the Windows\System32 folder.

3. Reboot and install from scratch the XCP-NG tools and finally it worked

Still not sure why they stopped working in the first place though... for now it is fine.

FYI, I am running XCP-NG 8.3 alpha (which is working great) with the latest released patched on a Intel NUC11ATKC4 (Celeron N5105 32GB ram).

borzel created this issue in xcp-ng/xcp

open Windows guest tools pre-install checker #152

Thanks for making compatible with NUC10, much appreciated

Hello there

Just updated from 8.3 alpha (updated to the latest patches) to 8.3 beta using XOA on a Intel NUC11ATKC4 and a Intel NUC8i5BEH.

All went well, great job and so far super stable.

Thank You
RP

@stormi

Update done on an Intel NUC11ATKC4 and a NUC8i5BEH, both are working fine

@stormi

I understand, I have snapshots to revert to but there are software running on that vm I prefer not to obliterate...

... so I can prepare a new win10 vm from scratch and check at each step and reporting the result.

I will report back here if it works for you.

Quick post to report that my home lab Intel NUC 11 N5105 is working without any issue since day one of the alpha release (not sure why you call it alpha then ).

Running VMs are: 1xWin10, 1xFedora, 2xUbuntu and XOA from source.

Thank you for supporting latest intel nuc!

@olivierlambert said in XCP-ng 8.3 public alpha :

xe-toolstack-restart

Done and it worked now all the VMs are displayed.

[21:24 xcp-ng-1 ~]# xe-toolstack-restart
Executing xe-toolstack-restart
done.

FYI vm154 memory is now reported.

Thank you for your help, if it counts as bug it is a small one: so far 8.3 alpha has been super-solid.

Have you considered mesh VPN like Tailscale?

@mauzilla

Have you considered mesh VPN like Tailscale?

@olivierlambert said in XCP-ng 8.3 beta :

@rRobbie can you disable/re-enable the "Auto power on" toggle, reboot and see if it works?

If it doesn't, if the problematic VM is hosted on a storage repository that's inside a VM on the same host? (could be a "dependency" auto boot issue)

I disabled / enabled the auto power on option, then rebooted the host and it worked fine. The vm started automatically along with the other vms with auto power on which started regularry the first time after upgrade to beta.

Btw, the vm is running on local storage.

Thanks
RP

@rRobbie

I quote myself to report a small issue, after the reboot following the upgrade to beta one VM did not auto power on-
When I realized some services were not available I went and started the VM myself.

The other two VM with auto power on switch did power on without issues.

Let me know if I can provide any other info.

Hello there

Just updated from 8.3 alpha (updated to the latest patches) to 8.3 beta using XOA on a Intel NUC11ATKC4 and a Intel NUC8i5BEH.

All went well, great job and so far super stable.

Thank You
RP

@stormi

Update done on an Intel NUC11ATKC4 and a NUC8i5BEH, both are working fine

xe-toolstack-restart

Done and it worked now all the VMs are displayed.

done.

FYI vm154 memory is now reported.

Thank you for your help, if it counts as bug it is a small one: so far 8.3 alpha has been super-solid.

Also, the totalizer seems to be correct: 14GB, what seems to be missing is the "green" chunk related to vm154.
From left to right: XCP-ng 1.8GB, vm104 4GB, vm153 2GB, vm152 3GB.

If it can be of any help, guest tools seem to work

@olivierlambert

Here vm153

I will be available for any test.

Hello, not sure the unusual behaviour it's XCP-ng or XOA related.

One vm does not show up in the RAM summary.

These are the active VMs on my Intel NUC

This is the RAM summary, vm154 is missing.

Odd but not problematic, just to let you know.
Thanks
