On the tuning suggestion, my guess, untested and purely from reading your paste, is that if something is genuinely holding sockets then raising tcp_mem buys headroom rather than stopping the accumulation, and your post#4 about throughput coming back on an xo_server restart points the same way.

It might be worth a mention to @Team-XO-Backend, since they would know whether xo-server keeps sockets per pool.

This is why I'm not increasing the numbers quite yet. Since this would only mask a potential issue. If an underlying cause is responsible, then this would be of interest.

Thanks for chiming in!

Did a much closer look and can indeed confirm that the network capabilities go up from kb/s -> MB/s immediately from xo_server restarts.

Comparing against the weaker XOCE

Strong:

net.ipv4.tcp_mem = 90147        120196  180294
net.ipv4.tcp_rmem = 4096        131072  6291456
net.ipv4.tcp_wmem = 4096        16384   4194304

Weak:

net.ipv4.tcp_mem = 41766        55688   83532
net.ipv4.tcp_rmem = 4096        131072  6291456
net.ipv4.tcp_wmem = 4096        16384   4194304

Adding the initial memstats I was looking at whilst trying to troubleshoot

$ cat /proc/net/sockstat
sockets: used 3478
TCP: inuse 37 orphan 0 tw 25 alloc 3149 mem 194631
UDP: inuse 5 mem 0
UDPLITE: inuse 0
RAW: inuse 0
FRAG: inuse 0 memory 0

$ cat /proc/sys/net/ipv4/tcp_mem
90147   120196  180294

Hello

This is an early start of a thread for documenting a potential issue. I will add to it with findings accordinly.

---

I'm having some issues with on XOCE instance, commit 7a187. Three times this week, it has gotten quite unresponsive with network trafic. And looking at the console give clues as to why:
"TCP: out of memory -- consider tuning tcp_mem"

The weird part is that this is my most beefy XOCE instance of all.
4 cores, 8GiB, management agent 10 (Citrix), Rocky 10.2.

In troubleshooting I tried restarting the XO-server service. And this seems to have resolved the issue for now. But TBH, I was looking at several point at the same time. So it is possible that it had resolved itself (unlikely but possible) whilst I was troubleshooting and reading up on tcp_mem.

My other XOCE instances are setup identically, and are actually a little bit smaller in the amount of RAM assigned. And they show no problems.

Failing XO instance connects to three separate 1Host pools.
Working XO instance connects to 1 HA-pool with three hosts.

Installation is done by a port of https://github.com/cloudrootab/ansible_role_xoce, adjusted for Rocky10 instead of Ubuntu/Debian.

Edit: I should also add that this XOCE has shown the same behaviour on both a recently updated XCP-ng host, and one that is two months behind on updates. Running on Dell Inc. PowerEdge R670 for each of the hosts (RAM on hosts has plenty to spare, roughly 50% utilization)

@florent

I'm seing the same behaviour as well.
To answer the questions you're asking for:

XO from source (7a187)

XO is connected to three separate pools. Backups work most of the times. But I've started seeing the same error. However, it seems intermitent. And somwhat random. Since it will generate an error from one VM, but not on another on the same host with the same SR etc etc.

can't compute delta OpaqueRef: <ref>
from OpaqueRef:<ref>, fall back to a full
can't connect through NBD, fall back to stream export
Backup fell back to a full

• There is an assigned backup-network, and it is the same as the management network. With NBD enabled
• XO can access all of the hosts on the management/backup network
• IPv4

I've taken a quick look, looks like it'll be solved as part of the Windows guest agent overhaul, so please look forward to that.

Thanks for the info. I will be looking forward to that, indeed.

@olivierlambert

Unfortunately the Rust-based agent is effectively not progressing. Last commit was months ago, and the 0.4.0-release was over 2 years ago, Issues aren't tagged for many months. Simple and easy MR's are left hanging in limbo.

I'm hoping they will show this project some more love and attention soon. Since I really like the idea of an open source Rust-based agent. As it is clear other things are taking precedent over it.

@olivierlambert

Thanks again for your input and recomendations! I'll verify that this is solved by having the LUN expanded to 8GB instead. Afterwards I'll mark your answer as the solution!

@olivierlambert

Thank you for your reply.

The reasoning here is that we are experimenting quite heavily at this moment.
And the thinking here is to have three LUNs each for their intended purpose.

LUNs
1 for VHD-based VDIs
1 for qcow2 based VDIs
The ones above will be used and modified quite a bit
1 for the Heartbeat. Being left alone to be as standard out-of-the-box as possible.

All of the LUNs reside on the same storage systems (Dell PowerStore at the moment). So my resoning here is that they're all on the same storage cluster, and therefore will be affected similarily regardless. Exotic corner-cases may of course show up.

But I will absolutely take your recommendations into account! And when we've stopped messing with the storage for the VMs. I will have the Heartbeat there on that as well!

@ronan-a

Sure

xensource.txt

Update:

We just expanded the SR to 2GB. And I'm still getting the same error.

Write permissions were verified by creating a vdi on the SR. And that was successfull with no problem.

Next step in our lab testing was going to be to enable HA. For this we chose to go with a 500MB Fibre Channel LUN.

• According to the docs, the minimum requirements are 356MB. https://xcp-ng.org/blog/2024/08/22/xcp-ng-high-availability-a-guide/

However, when I try to enable HA I will find an error in the logs saying SR_SOURCE_SPACE_INSUFFICIENT. (Full log down below).

So my question then becomes. Are the docs out of date, or could this possibly be something else under the hood?
Note: I'm currently waiting on the storage guy to expand the SR to 1GB.

Update: Changed title to better describe problem

@poddingue

I have done some more testing.
Windows Server 2022 is also affected. 9.1.145-77

I also tried the latest WindowsPV drivers from Vates, on Windows Server 2025. 9.1.200-0. And the "problem" still persists.

It is a very low impact and low importance "problem". Since it is afaik purely costmetical.

ping @poddingue for visibility as I believe I've found the trigger for IPv6 expanding... Live Migrations

Ah sorry I read it too quickly. This panel is only there in some occasions, but I see the point of only displaying it when we click on a relevant element. Feedback for you @julienxovates

While on the topic of the tree-view panel.
Have you noticed that the indentation changes if there is a chevron indicating that there are VMs on a host? Making it so that the hosts no longer are alinged vertically

@olivierlambert said:

@jr-m4 do you know you can collapse the side bar? Use the hamburger icon just after "Xen Orchestra" title to do so.

Yes, but it is the rightmost pane that I'm not agreeing with.
The left most "tree-view"-sidebar is quite usefull. And has imho good potential.

@colomb said:

I really miss the description column XO5 has in the default/home view. I understand space is limited for the tree view, but maybe it could appear when a host is selected in the tree view?

In XO6, you will see it if you click on the eye at the end of the row, then on the right panel.
Is this OK ?

Personally I don't really find the rightmost pane/section all that usefull. It's to narrow to have any clear information. And it also leads to the other panels being smaller than they (imho) need to be able to show their base information as well.
This is especially noticable when using windows sizes narrower than 1080p.

The rightmost pane I hope will get either removed, and redone in UI v7. Because right now XO5 is far more informational than that is.

Sorry for jumping on with my two cents.

@poddingue

Thanks for your input.
Yes I'm aware that basically everything on the VM is incorporated into the snapshot. Including settings and metadata. This is acctually why I was surprised that the creation date wasn't preserved as part of that metadata. And as you say, if one uses that metric to track VM history. Then it can, and will, throw you off.

I'll gladly submit this as a feature request. But my gut feeling is that it is more akin to a bug than missing feature per se.

Thanks!

@TeddyAstie

I do not have Citrix ones. This VM was pretty much freshly installed to test Windows2025 on as pure Vates-maintained stack as possible.

Update: Please note my post above. Tha this seems to be triggered by live-migrating the vm
