We pushed the updates to the xcp-ng-updates repository: https://xcp-ng.org/blog/2026/05/21/may-2026-updates-3-for-xcp-ng-8-3-lts/

Changed since the initial announcement, xen was updated with the proper vulnerability fix and an update to sm was added to fix an issue on LVM-based SRs with CBT enabled.

Thanks everyone for your feedback!

New security update candidates for XCP-ng 8.3 LTS (kernel, xen, intel-microcode)

i tested on one of my extra pools and so far i didnt see any issues. Grated i dont do much on that pool but i created a ubuntu 26 VM without issues.

Ill wait for full release to do my main pool.

@olivierlambert lol okay got it

@stormi I getting a response to reboot after applying to master.

anyone know if applying these two patches requires rebooting?

Just to add more data.
Xen Orchestra, commit 56b17
Master, commit 56b17
All patches on host are done.

the ipmitool works on my asrock MB but i dont see it in XO host screen.
I also didnt see it on xo6 interface.

yeah that was it, i removed the ip address from cfg file and it working now.

Updated to commit -db8ad this morning and backup is working.

I got back into v5 url once i removed LISTEN_ADDRESS="" from my xo-install.cfg

the backup ran on Xen Orchestra, commit cb85e

@florent I posted this in the v6 master thread, but it opens to the old interface but sits with a still loading message.

@simonp I downloaded the branch but i have no idea how to run a backup in v6 interface and v5 isnt working with the latest updates to XO. How do i run a backup job manually in v6?

I just got hit with the backup error, not sure what version i was running but it was likely a3139 or higher. I have XO rebuild each morning to fetch latest updates.
Error I can find (interface jumped to v6 so still learning)

Can't init vhd directory without using alias

Backup to NFS share

I ran into backup failure this morning, I think someone else mentioned about it in another post. I went to check if there was a newer version of XO since usually things get fixed quickly. so I updated XO to build 9dbc09011.

Few things

• XO loads up now using interface 6 as default.
• As someone else mentioned, about version is blank in v6.
• When I click on V5 link it brings me back to V5 but its broken for me. Sits there saying loading.
  
• Havent tried using guide to go back to V5 to see why backup failed. Not sure if V6 has enough to figure out backup issue since i havent used it much.

Update: looks like it failing to get something on v5 url.

Update 2: I had to remove LISTEN_ADDRESS="" from my xo-install.cfg to get version 5 working again

applied latest patches to my two host pool without issue.

curious how does this work, dont you need to put in a username and password/IP address for ipmi details. I havent looked at docs or tried this out, just wondering. I think on ESXI i had to setup the ipmi with such details before i could issue power on etc.

also noticed a new issue- seems like changes i had in the /etc/xensource/usb-policy.conf file for usb was lost during the upgrade.

I have some usb comm devices i use with a home assistant VM and they were gone post the upgrade.

anyway to make those change last post upgrade? Maybe make then options in gui so a config file can always be reflective of gui settings?

@stormi The original thread is here
https://xcp-ng.org/forum/topic/10374/xcp-with-opnsense-vm-running-att-bypass-is-vlan-0-network-possible/14?_=1766094991961

updates done on my two main servers and one dev box i happen to power on today. so far so good.

PS: Any way to get the following included on the next update for networking? I need it to run a scenario with opnsense vm. right now i have a script i run manually after rebooting the server.

ovs-ofctl add-flow xenbr3 "table=0, dl_dst=01:80:c2:00:00:03, actions=flood"

thanks

@acebmxer said in ️ XO 6: dedicated thread for all your feedback!:

@marcoi check with who wrote your script to install XO from sources.

https://github.com/ronivay/XenOrchestraInstallerUpdater - this has a option in config file to enable v6 during install/upgrade.

or try -

cd /opt/xo/xo-web
yarn run turbo run build --filter @xen-orchestra/web

that worked thanks!

what build version of XO will start showing v6 interface? I may have missed the announcement.

i am currently on Xen Orchestra, commit f4988
Master, commit f4988 and when i try the menu link

I get a new tab with error below

anything i am missing? or is the XO build not out yet?
