assigned the Widows Server 2022 to the VM, waitted a looooong time and the VM eventually did boot.

Hi,

I am still on XCP-NG 8.2.1. I am trying to update the Windows Guest Tools driver for windows 2022 following the CVE that flashed up on my screen and I get the following message:

When I ran the XenClean tool as suggested, the VM doesn't boot and I had to revert from snapshot.

Could anyone please advice?
Thank you

@Pilow said in Unable to update XOA:

or a good reboot of the XOA if there is no backups at this time

Rebooted XOA and Hypervisor. I managed to install the template. Any sugestion about the time sync issue?

@Pilow said in Unable to update XOA:

could you verify the time/date on XOA, and XCP host where you want to deploy it

My time is completely wrong.
XOA:

[09:08 01] xoa:xoa$ date
Mon Dec  1 09:08:42 AM EST 2025

Hypervisor:

[14:06 uk-dc1-prod-hv1 ~]# date
Mon Dec  1 14:10:06 GMT 2025

I just ran timedatectl set-timezone Europe/London but not sure how to sync time

@Pilow said in Unable to update XOA:

do you see a task progressing / failing when installing the template from the Hub ?

Yes I do.

@fred974 v6.80.6 is definitely very old, and did report MemFree, we ship v7.30 with XCP-ng 8.2. You will likely want to update it, from the "XCP-ng tools" SR.

Probably because I installed xe-guest-utilities from ububtu repo.. I tried to update from the CD and got the following error:

@yann said in Memory reporting incorrect values:

@fred974 the tools should be reporting the value from MemAvailable, so buffer/cache should not be considered as in-use.

Doesn't seem to be the case

It would be great to have a bit for details on the memory so we can monitor the system better.

@olivierlambert But all modern OS will use the RAM as cache for performance etc. So how can I ensure I get the correct info? At the moment I bombarded with email saying high RAM usage

@olivierlambert said in CPU reporting incorrect values:

Check carefully your htop output. See the huge yellow bar? That's the buffer/cache used

So Xen Orchestra see cached value as ram in use and not the actual active used ram?

Hi,

Could anyone please help me understand wich value I should go by when looking at CPU resources?
XOA:

XO Lite:

Server htop

According to Xen Orchestra, I am using almost all of my 8GB RAM where as in htop, I am only using 1.74G.

Which one should I trust?

Thank you

@olivierlambert said in What are Custom field used for?:

I would go against storing secrets though

lol Thank you for the advice

Hi,

In the advance tab of any VMs, we have the option to create custom field and I wonder if anyone please explain what it is for. I found it when trying to find somewhere to store the VM Root password
