    @poddingue Thanks for looking into this! I checked the bulk "Reconnect to all hosts" action as well, and you're right — it doesn't work either. It only works if I select a single SR, open its page, and use the "Reconnect to all hosts" action from there.

    @ludalm13 the PCI-DSS Requirement 10 part helps your case, I think, because it turns this from a nice-to-have into something an auditor will ask for. You're not the only one asking, either. The Feeder request @dknight-bg linked is at four votes now. I'll also point the XO backend folks at the PR directly, a tag in a forum thread is easy to miss in a busy week.

    Just as an update on this. Did get the migrations working. Still haven't gotten the backups working. Pool is still stable otherwise. Have managed to get backups by using Veeam so it's not to much of a problem.

    Hi, This was fixed in Latest. But if you need to stay on Stable, you can open a ticket to have a patch.

    For anyone else who steps through this, I've also installed the latest xen-guest-agent with the below process. Repeat for each host in the environment, 1 at a time from your Helper VM. ### ssh into your helper ### oc debug node/fedora-cmp-1/2/3 chroot /host cd /var/tmp curl -LO https://gitlab.com/xen-project/xen-guest-agent/-/jobs/6041686376/artifacts/raw/RPMS/x86_64/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm sudo rpm-ostree install /var/tmp/xen-guest-agent-0.4.0-0.fc37.x86_64.rpm mkdir /var/tmp/xga && cd /var/tmp/xga rpm2cpio ../xen-guest-agent-0.4.0-0.fc37.x86_64.rpm | cpio -idmv ### From your helper... DRAIN YOUR WORKERS ### oc adm drain fedora-cmp-1/2/3 --ignore-daemonsets --delete-emptydir-data ### log back into fedora-cmp-1/2/3... ### sudo systemctl reboot ### from helper ### oc adm uncordon fedora-cmp-1/2/3 ### login to fedora-cmp-1/2/3 ### chroot /host sudo systemctl enable --now xen-guest-agent And then from XO this is what your VMs will look like.

    Have you read the link I've sent? It explains exactly the reasons and answer your question You can imagine that if we have hundreds of 3rd party scripts, each doing their own way to install, it means we'll have to de facto support them all, despite it's unrelated to Xen Orchestra itself. Which means spending resources instead of working on Xen Orchestra directly (or fixing XO bugs). That's why it's preferable to open a ticket in the Github repo of the script creator, because that's exactly there you'll find the right answer, and also making sure the script creator could even fix their scripts if needed. If you need community support in here, you have to install it by following the official documentation: https://docs.xen-orchestra.com/installation#from-the-sources

    Just a reminder for myself, or other people in need in the future thanks again for all people who helped me understanding this Had to reinstall my entire XCP system, and almost forget how to configure Ldap plugin to only allow my admin accout to login So here's my Ldap plugin conf, to allow only admin user (member of specific group) to login. my AD is a windows 2K19 server with active directory without ssl. URI : ldap://dc.domain.net:389 no certificate info base : dc=domain,dc=net Credential : Fill = tick DN = full DN of service user (CN=xen,OU=service_account,DC=domain,DC=net) password = password of this account it's a simple account with no specific right, can only read AD and login User Filter, where it can stuck (&(sAMAccountName={{name}})(memberOf=CN=SG-XCP_Admin,OU=service_account,DC=domain,DC=net)) in real my OU have spaces inside their name, it work anyway. SG-XCP_Admin is a security group having my admin users inside ID Attribute : sAMAccountName and that's all.

    @Andrew many thanks. As do I. See my OP. A failed build doesn't break XO. It leaves the previous successful build in place. My post wasn't to ask how to fix my problem, but to point out the issue to others who might care to know (see my last post). Cheers.

    This is an old thread, but I ran into this myself recently. While there is a link to deleting the entire XO configuration, I think I fixed it with a less drastic solution. Remember: I'm just a random dude on the internet posting dangerous commands to try. It worked for me, but your mileage might vary. I run Xen Orchestra in a container (Xen Orchestra, commit e8733 at the time of writing). So I got a command line in the container with: docker exec -it xoa bash Then I ran redis-cli to get a redis command prompt. I typed KEYS * to get a list of keys. One key I saw was: 7) xo:server_host:172.30.0.214". That's the IP of the host I was trying to join (the master of a single-host pool). So I ran: del xo:server_host:172.30.0.214 Then I restarted my container with docker restart xoa. After that, I was able to successfully add the host to Xen Orchestra. Maybe this will help someone else. It got me working again.

    @jsox79 No I did not. Disclaimer - I inherited this FreePBX system and don't know a whole lot about it. Once I got it to boot, I tested by calling my cell from a desk phone and making a page, and both worked as expected so I'm considering everything to be working. Didn't realize re-registering modules was something I may have needed to do.

    Bit of a necro-post, but we're mid migration of storage/VM hosts/pools. I have a single win11 VM that's UEFI (not secure boot). It runs just fine on our old 8.1 server that we're migrating off of. If I provision a new UEFI VM on the new pool and point it at the shared storage VHD, it refuses to boot with the same "The emulator required to run this VM..." error OP posted. I've tried restarting the toolstack and "updating the Secure Boot certs" on the host server. Any guidance very much welcomed, I was unaware that this VM wasn't booting on the new pool (the VM is off a lot of the time), and we're a couple weeks from this project completing (and the old server being WEEEd).

    Not with XOA then (yet). We might switch XOA to UEFI in the future for that. If you are using XO from the source, sure, you can do that

    @bleader Hi, After a restart of the entire host, port 6640 is now listed when I trigger ss. But, unfortunatly, tunnels are not working, every VM on this host loose connection to other in the same sdn network. Exemple with an ping between two hosts : 2025-10-09T12:22:54.781Z|00026|tunnel(handler1)|WARN|receive tunnel port not found (arp,tun_id=0x1f1,tun_src=192.0.0.1,tun_dst=192.0.0.3,tun_ipv6_src=::,tun_ipv6_dst=::,tun_gbp_id=0,tun_gbp_flags=0,tun_tos=0,tun_ttl=64,tun_erspan_ver=0,gtpu_flags=0,gtpu_msgtype=0,tun_flags=key,in_port=33,vlan_tci=0x0000,dl_src=56:30:10:5c:4d:ad,dl_dst=ff:ff:ff:ff:ff:ff,arp_spa=192.168.10.10,arp_tpa=192.168.10.20,arp_op=1,arp_sha=56:30:10:5c:4d:ad,arp_tha=00:00:00:00:00:00) 2025-10-09T12:22:54.781Z|00027|ofproto_dpif_upcall(handler1)|INFO|Dropped 61 log messages in last 59 seconds (most recently, 1 seconds ago) due to excessive rate 2025-10-09T12:22:54.781Z|00028|ofproto_dpif_upcall(handler1)|INFO|received packet on unassociated datapath port 33 If I migrate the VM on the third host to another, network came back. This is very strange, because the network I've choose to test it is one of firt of all created, not last one, so it have worked before, and not now. I don't understand why and what to do...
