I have a problem after commit 6e508b0.
I can no longer select the export method.
With 6e508b0, all are ok

Commit a386680

Commit 6e508b0

At a certain point, I don't know when because we are talking about a home lab here.
I could attach the USB HDD same as a virtual HDD and I could put exclusions on it

More detailed:
At the moment I have this:
A VM with TrueNAS that has:

• sda 100Gb, the operating system
• sdb 2Tb, the first hdd to use in TrueNAS
• sdc 2Tb USB, clone of sdb 2Tb made in TrueNAS

I want to backup the TrueNAS system, which means only sda
I excluded sdb via [NOBAK] [NOSNAP]
But I can no longer exclude sdc via [NOBAK] [NOSNAP]

Is there a possibility to implement the same options as for disks, for VUSB to?
I mean the option to use [NOBAK] [NOSNAP].
Before the update, I saw the USB-HDD as a normal disk that I could attach to VM and use the [NOBAK] option to excluded it from the backup.
I have XCP-ng 8.3 is installed on the server.

This is what I was thinking

• [NOSNAP] to be like SDA and disk 3
• [NOBAK] to be with SDA and disk 2
• In both cases disk 4 is excluded

From my point of view, it should be with "OR" and if the condition is fulfilled to execute.
E.g :

• if I have "[NOSNAP] 'VM name' " not to execute snapshoot
• if I have "[NOBAK] 'Vm name' " not to execute backup
• if I have "[NOSNAP] [NOBAK] 'Vm name' " not to execute snapshot and backup
  But if you make a backup, remove only what is with [NOBAK]

It's not really necessary.
As I said, I have 3 x DC and I restored them in the test lab and they were ok.
All three were backed up at the same time with a single normal backup task.
Below is the task I was talking about.

@fatek
AD has a maximum period of difference between Domain Controller's and as far as I know it is 24h.
If you don't do this, the oldest one will be out of sync and useless.

I have something like this and I have no problems so far.
The only thing is to do them all on the same day.
I have a task that backs up all three VMs at once.
And the restoration is done the same way, all from the same day.

@AtaxyaNetwork
thank you

@olivierlambert
ok, thank you

@AtaxyaNetwork
off topic,
how can I activate the dark mode for XOCE?

We need to talk to the XCP-ng team and see if they can provide the module for the xen kernel.

Try to install lm-sensors and see what it detects.
It seems to me that the kernel it does not have drivers for IPMI BMC KCS.
My fans have 8000 - 8100 rpm

yum -y install lm_sensors
sensors -v
sensors-detect
sensors

Did it come fully equipped?
Did you install Lenovo signed HDD in it? Or you have compatibles HDD.
If you have compatibility, try to put a HDD with (original) Lenovo firmware.
I had the same problem with an Lenovo ThinkSystem SR630, I had installed a Lenovo non-firmware HDD, all of them. I bought one with Lenovo firmware, I installed and the problem disappeared.

@olivierlambert
Thank you, this solve the problem

I am on commit 17ed63fd58451737e6ca0f9899332b49861b2407 and I can't export VMs.
I get "unknown error".
I have on one server XCP-ng 8.3 and I can export VMs with XO-lite without problems.
I tried to export them with or without compression

@manilx I use the last one - Windows Server 2008 R2 (64 bit)
Steps are:

1. On XCP-ng 7.5 create a VM with template Windows Server 2008 R2 (64 bit), with out hdd
2. Copy the VM to XCP-ng 8.2
3. Import HDD to XCP-ng 8.2
4. Attach the imported HDD to VM
5. Start VM

If you get BSOD you need to insert xenbus driver.
You have them on https://ncloud.neandria.ro/index.php/s/89i8D6E3nDX99G7
I use Dism++ for insert them, just mount de disk to other windows
https://github.com/Chuyu-Team/Dism-Multi-language/releases

What I did.
I installed XCP-ng 7.5 from https://updates.xcp-ng.org/isos/7.5/ , on VirtualBox with the ability to enable Nested VT-x/Amd-V
Copy templates for windows 2008 in the current XCP-ng, be it 8.2+, as in the photo. The template is to recreate the existing VM and attach the existing HDD

Download the XenServer 7.2 image from http://downloadns.citrix.com.edgesuite.net/12636/XenServer-7.2.0-install-cd.iso

Open with 7zip or equivalent.
Extract XenServer-7.2.0-install-cd.iso\Packages\xenserver-pv-tools-7.11.0-1.noarch.rpm
From the above file extract xenserver-pv-tools-7.11.0-1.noarch.cpio\opt\xensource\packages\iso\guest-tools-7.11.0-1.iso. Here you have PV drivers for windows 2008

Mount and install the PV driver in the VM and everything is ok

Or already extracted on https://ncloud.neandria.ro/index.php/s/89i8D6E3nDX99G7

The template must be for windows 2008, otherwise the PV drivers will not install properly

And I confirm this, the problem has disappeared.
Thank you
