Hello !
Not enough CPU and not enough RAM, because the RAM is 32G (dynamic max) and the CPU is 16 (8 socket 2 core). The host has max 8 CPU and 27G ram.

Unfortunately, I also get "body timeout error" errors during backups. I run several xen-orchestra servers, but it only occurs where the version is up to date. It also occurs with random VMs, and even with metadata backups. I've attached this morning's log. [xo-server.log](Invalid MIME type)
Which ISO are you booting?
The default Alamlinux 10 only supports CPUs from amd64 v3 upwards. You need to download the amd64 v2 installer separately.
@anthoinebThe problem still persists; when can we expect it to be resolved?
Hello !
I'm a senior linux/unix administrator/system engineer and I'm also working with networks (L2/L3).
I first started using virtualization in 2006 on a Debian/xen basis, then Xenserver 5.5 -> 6.0.2 -> 6.2 -> 7.2 -> xcp-ng ...
I've also been using xen-orchestra since the first public version.
@andSmv thanks for the reply
The server is a home test, power consumption is more important than stability, so I'll try to recompile xen.I guess it will be enough to recompile only version 4.13.4 ?
PS.: I just looked at the source code and I don't see that there is a switch to turn it off. I will modify mwait-idle.c to see if it works 
PS2: Done :
[09:50 home-xcp ~]# xenpm get-cpuidle-states 0
Max possible C-state: C9
cpu id : 0
total C-states : 5
idle time(ms) : 134037
C0 : transition [ 5351]
residency [ 6507 ms]
C1 : transition [ 13]
residency [ 15 ms]
C2 : transition [ 71]
residency [ 120 ms]
C3 : transition [ 701]
residency [ 6956 ms]
C4 : transition [ 4566]
residency [ 120437 ms]
pc3 : [ 13371 ms]
pc6 : [ 23594 ms]
cc3 : [ 14446 ms]
cc6 : [ 63719 ms]
The intel.c had to be modified to be correct. Let's see how stable it will be.
@olivierlambert I updated the XO from source, it looks good for now.
@jsox79
Initrd does not include the xen drivers. You need to regenerate and you will be fine.
boot with sysrescue CD, and in a chroot olt environment you can create a new initrd with the xen drivers.

@pierrebrunet This is the same error, but it occurs more often when saving metadata. I'm attaching the logfile. xo-backup-error-log.txt
The problem is that my VM backups don't run either, because I still get a timeout. This morning out of 11 VM backups, 2 failed, on Tuesday 1 failed, 20 were good.
@poddingue httpInactivityTimeout changed the only thing for me, I received the email half an hour later that the metadata could not be saved.
Narrowing it to something that changed between the late-November 2025 build and the July 2026 ones gives everyone a better place to start than "it just times out".
The backup function was definitely still good in the 2026-05-28 build. So I think you should look at the last 1 month.
@pierrebrunet I'll try to collect the logs.
However, I can't even backup VMs. What's interesting is that the error always occurs with only 1 VM or 1 Metadata backup. This morning's backup report:

the ones where it works and the ones where it does not work.

@Bambos It's possible, but with the old version, there was no such problem, and nothing else changed except xen-orchestra.
Unfortunately, I also get "body timeout error" errors during backups. I run several xen-orchestra servers, but it only occurs where the version is up to date. It also occurs with random VMs, and even with metadata backups. I've attached this morning's log. [xo-server.log](Invalid MIME type)
@pkgw I tested it with a cluster size of 2 megabytes. I got similar results to those with the default size.
Might be interesting to test a different cluster size and see the impact
I tested it with a cluster size of 2 megabytes, and nothing changed
