I migrated all the VMs to the other host (.214) and did the install.

post-install I got the iSCSI drives for host file storage reattached to the new 8.4 host (.215) but now I can't seem to get the other host (.214) to (re)join the pool. From XenCenter it says it's already a member of the pool but none of the VMs appear in the list. When I ssh to the host (.214) and run xe vm-list -s <xx.xx.xx.214> it says "authentication failed". From the control panel it says that no vms were found.

Not sure how to proceed from here. Do I need to create a new pool for the 8.4 host (.215), try to promote .214 to pool manager and then migrate?

Clean installation of XenServer 8 (2025-04-22) succeeds without issues.

In-place upgrade from XenServer 8 (2024-12-09) to XenServer 8 (2025-04-22) also fails with the same target-platform error.

However, in-place upgrade from Citrix Hypervisor 8.2 CU1 to XenServer 8 (2024-12-09) is successful.

From hour own investigation we think the problem has something to do with the numa assignment.Why: we see at many times that de vcpu assignment is not assigned to a single socket, but assign accros cores on both sockets. This leaves the preffered single socket numa.

I have a dumb question about Rolling Pool Upgrade.

I have a customer with 42 host in the same pool for Citrix DaaS Workload. I plan to do a Rolling Pool Upgrade but Citrix estimates the upgrade for about 35 min per host, that's means the whole upgrade will take approximatively 24 hours.

Is it possible to use the automatic Rolling Pool Upgrade and to select a subset of servers to make some batch (ex : 10 servers at a time).

Or do I need to do a manual upgrade.

Thank you for your help.

I have a pool with two Hypervisor 8.2 servers. We decided to buy two new servers (to current ones are 10 years old...) to replace them.

Is it possible to install Xenserver 8 (8.4 being the current one, as I've seen), add the new servers to the pool, migrate the VMs then remove/kill the old servers? Is that the best path? Should I replace the servers in some other way?

Thank you,

Roberto

I have a freshly installed pool consisting of two hosts running Xenserver 8.4. The pool is licensed as "Xenserver Premium Edition". The Normal Update Channel is selected. When attempting to synchronize with the update channel, I get the message: "Update your server license to apply software updates to XenPoolxx. Synchronization isn't working. If I remove the license from the pool, it operates as a 90-day trial version, and synchronization and installation of updates work. I've already generated a server status report and run the health check at cis.citrix.com. No issues were detected.

Any recommendations on how I can synchronize and install updates with "Xenserver Premium Edition" license?

Best regards!

all my attempts to install XenServer 8.4 on a ProLiant DL20 Gen10 have failed so far.
The installation always stops at the hardware detection.
A search has now revealed that this server is not in the HCL and is therefore not officially supported, only ProLiant DL20 Gen10 Plus or  ProLiant DL20 Gen11.

https://hcl.xenserver.com/servers/?serversupport__version=21&vendor=6

Any idea how to install the XenServer anyway to at least check if it runs on the hardware even if the scenario is unsupported?

Regards
Roy

I'm trying to figure out how can I install updates or hotfixes on the new XenServer 8. 
I'm aware of the new update process, the Normal channel and the Earley access channel nevertheless from what I can see both require internet access.

Is there way to download the hotfixes like we have done it with Citrix XenServer 8.21  and then apply them on the hypervisor ?

Thank you. 

i have a problem after reboot my (Dell 440 ) with my  Xen Hypervisor 8.2 CU1 the iSCSI Storage ist not attached.

The Systme is already running for 2 Years without a problem. 

both Host shows multipath is not active. Biut they are active on the system.

Repair did not helped.

While updating XenServer 8, i am getting this error. It is running with XenServer 8 (Fresh Installation).

I do not see any known issues as such from the release notes, anyone facing the similar issue ??

I have a quick question regarding a Network installation and the post-install script that can be used to perform post build configuration.

in the past XenServer was used with the initd system of booting, while the latest version uses systemd

the initd used start-up scripts starting with 'S' in the relevant run level folders (rc3.d, rc5.d, etc). That means that the post-install script just needed to copy/link in the relevant scripts to get the first-boot script to run after the reboot of the server after the system build.

Systemd requires you to run a command ("systemd enable <'script.service'>") to enable the bootup scripts to run. So for example the old post-install script might have looked like

#!/bin/sh
touch $1/tmp/post-executed
wget http://192,168.10.100/first-boot-script.sh -O $1/tmp/first-boot-script.sh
chmod 777 $1/tmp/first-boot-script.sh
ln -s /tmp/first-boot-script.sh $1/etc/rc3.d/S99zzpostinstall

but the new one should look like (where "first-boot-script.service" is the config file to run the bash script)

#!/bin/sh
touch $1/tmp/post-executed
wget http://192.168.10.100/first-boot-script.sh -O $1/tmp/first-boot-script.sh
wget http://192.168.10.100/first-boot-script.service.sh -O $1/tmp/first-boot-script.service
chmod 777 $1/tmp/first-boot-script.sh
cp $1/tmp/first-boot-script.service $1/etc/systemd/system/first-boot-script.service
systemctl enable first-boot-script.service

unfortunately the last line of the script does not work as the systemd environment has not yet been initialised.

I can either run this last line manually after the system gets rebooted, then reboot a second time (after which it works as expected), or run the /tmp/first-boot-script.sh manually.

I'm trying to get the installation to work as automatically/seamlessly as possible, so does anyone know how to enable the service via the post-install script?

What we want to do.........

Configuration and install Citrix hypervisor using best practice for a 2 site active-active setup isolated from each other.

• Site DC1: 4 * DC1 hosts with DC1 shared storage
• Site DC2: 4 * DC2 hosts with DC2 shared storage
• Both sites will need to connect to Single Shared storage too where we have the master image for building and updated Citrix VDI.
• The HPE Shared storage at the corresponding DCs will be used to deploy the VDI to and will need to be set so it supports thin provision
• We have current pool 8 Citrix Hypervisor already using the 8 licences, but we want to do a side by side build  and then migrate users in phases then shut down old, how can we utilise the licenses already to allow this and will it allow the same licenses to be used twice?

For ease of understanding above please see a diagram of how the above should look on the new setup .

anyone managed to get a XenServer installation onto a HP ProLiant server using PXE/TFTP boot and HTTP source location?

I've got the TFTP boot working as per https://docs.xenserver.com/en-us/citrix-hypervisor/install/network-boot.html

I've also got an answer file configured on a HTTP server which is being read successfully after the TFTP Boot (UEFI Booting with grub.cfg file), but when it comes to the source  location on the same HTTP server, I get an error message "Unable to access repository (url, http://10.1.1.1/XenServer/)" (NOTE the web server is running on 10.1.1.1)

If I remove the answerfile entry from grub.cfg so that it becomes a manual installation, and I specify the source location manually as http://10.1.1.1/xenserver/ it comes back with "A base installation repository was not found at that location".

If it point my browser at http://10.1.1.1/xenserver/ is successfully lists the contents of the ISO I copied across (even the .treeinfo file)

My lab is a very simple, flat network on a 10.0.0.0/8 address range

Any pointers to where I might be going wrong gratefully received.

Regards

Ken Z

As an aside, anyone know how to get the installer to auto-run once the TFTP boot has occurred? it stops on the grub menu waiting for the user to press Enter

My questions is what does it take to do it?, What does it requires? Any special hardware requirements? How does it get setup?

It's on a Lenovo TS140.

Ubuntu, Windows 10, ESX, LVM, and any other product installs on the machines without a problem except XenServer AKA Citrix Hypervisor.
