XS License question. I spun up a XS host, got a license file from my partner, imported the license file on my CVAD license server and it does not appear on it. Am I doing something wrong? I noticed the hostname of my cvad license server (winsvr22) does NOT match my XS hostname (xenserver-sabcdefg) obviously, could that be the issue?

How do you calculate the vCPU for XenServer?

XenServer - Live Migration Hello Is it possible to use a dedicated network for Live Migration ? What is the default and the best practice ?

Since the update of the XenCenter I see faulty CPU values see screenshot. Does anyone have the same problem?

I installed a single XS host to play around with it. Connected to cvad, deployed some vdi, all good. a few questions for the experts as i'm a 15yr esx guy...

1. is there a recent tasks to see what the host is doing like esx has?

2. can you install xentools from the gui onto a vm? is there a way to see from xencenter if xentools is running

3. what happens when my license expires in a few months? will it continue to run or be dead in the water?

So, we've been a Hyper-V shop for like 6+ years now. I haven't done vSphere in freaking forever. I need to bring up a 3 server cluster for a specific use case. Has anyone blogged/used a "Best practices deployment guide" for vSphere that they could point me to?

@Nick Casagrande 15 year ESX guy.. What deployment guide are you using? Hook me up. 😄

none...just playing with it....pretty simple honestly...

install the iso, install xencenter, use http://ipaddy when connecting it to cvad...

Hey Team, a customer is using a XenServer 8.4 (Patched 29th of March) Pool with a configured Bond (2x 25 GBit = 50 GBit) for MGMT, which is primary used for XenMotion. When doing live-migration of VM's (Storage is NOT changed) there's only used a maximum of 802 MB/s which is way to slow. Any known issues or custom-configs which should be done to speed up the throughput? In theory there should be a max througput around 3-6 GB/s. Datacenter is in the same location, attached to 100 GBit Switches, so theres no technical brake at the infrastructure-side. Thank you!

When will we get VBS in XenServer? That's really needed 🙏

XenServer - MCS Master Replication Hello ! Does anyone could confirm me that is possible to export the MCS Snapshot of the master to another Pool to create a new MCS Catalog ? When the import on the second Pool, do we need to recreate a VM or the snaphot is usable as this ?

just caught this from the cybersecurity forum on reddit - not sure if y'all have seen it but given how widely used the tool is you might check your seals... https://zerodaylabs.net/rvtools-bumblebee-malware/

XenServer - Intellicache Hello everyone, I try to found a documentation about the sizing of the local storage when using Intellicache with MCS, but I don't. Does anyone have input to share ?

Hello, Does anyone have any experience running VDA's on Proxmox? They're not listed as a supported hypervisor, but I'm not sure thats primarly for using hosting connections/mcs etc.

It works, but as you said. No power management nor provisioning.

Buts its probably more efficent to use Xen if your plan to move from another hypervisor

Yep, but unfortunately Xen doesn't work natively with the backup solution, so trying to find the path of least resistance :D

I am having such a bad time, bad perf with W22 and XS8.4 AMD, very high CPU usage. We had to stop our rollout. Same W22 PVS vDisk on XS8.2, it's flying. It's Dell PowerEdge R7425. I found some had issue with the NUMA affinity, CPU scheduling on XS8.4. XS8.4 AMD with our W16 seems to work well.

Hi Folks, we are strongly considering migrating our PVS workload from XS to Hyper-v Windows Server 2025. Any feedback? Better perf? Main reason for us is VBS/cred guard, perf and overall support, more knows how to manage Windows.

Hi. Where can I download ESX 9 for homelab/testing without need VCF subscription? Maybe someome can provide the ISO file? 😇

So, looks like Broadcom is killing our VMWare Reseller partnership as well. Sigh. Where can you buy resell licenses these days now? Anyone dealing with this already?

Yeah, had my company's partnership terminated as well unfortunately.

To my knowledge, for homelab you can take the VCP-VCF exam, and sign up for VMUG Advantage, and the combination is supposedly supposed to provide you with home lab licensing (for personal use only). Other than that, you're stuck with using an eval.

Anybody know if there's ever going to be a Packer builder for XenServer that works? The one that's out there is ancient

Hey, I'll share what I learned after 1 month struggling with W22 performance (worse perf I ever faced) and XenServer 8.2 or 8.4 AMD processor. 1. We had good perf with W16, same setup 2. Being fully up-to-date didn't resolve the issue, including our Dell host stack and vDisk. 3. The bottleneck was the CPU, very high CPU usage for processes. 4. The issue is because NUMA, we have 2 × AMD Epyc but the amount of RAM was not good. For correct NUMA node, you must get an integer dividing cores by nb of DIMM. 5. W22 is more NUMA aware than W16, it explains why W16 was performing OK. 6. I have XenServer Intel CPU, 2 processors also and the performance is good, not sure yet if at the same level than Hyperv but clearly not as bad as AMD. 7. Really the issue is XenServer + AMD + W22 How did we fix it? We migrated to Hyper-v .... the way hyper-v handle NUMA works better, even if 32 vCPU out of the 128 vCPUs are not used (the 128 vCPUs are used in XS and it could be the issue), the performance is at the same level if not better than W16. I have a case with Citrix but so far, no fix and tbh I don't care, we're moving to Hyper-v and perf is really awesome!

So with more people asking for XenServer for on-premise pools, I was looking for a shared storage cluster that could be deployed on the XenServers to use their local storage and cluster it as iscsi for the XenServers themselves. Landed on PetaSAN. Looks pretty slick. Anyone else done anything similar to get a "nutanix" style setup on XenServer?
