    @paco On the stuck server, could you warm migrate the vms to one of the other hosts? Or could you shut down a VM at a time and cold migrate them? The second option is certainly not ideal, but maybe?

    Hi, Latest XOA, with fully patched XCP 8.3 here. I'm fiddling around again with NBD+CBT in backup jobs (was avoiding CBT for a time, to reliably control my backups and avoid unnecessary KEY points) in the context of THICK SRs to spare some space. I know that CBT is reset when migrating from one SR to another. But here is what I encounter : VM has no CBT enabled on its VDIs, it is on a SHARED SR in a pool of 3 hosts backup option changed for NBD+CBT, was only NBD before CBT is enabled on the next run by the backup job, I get a delta (was expecting a FULL ?) next run, delta, as expected i migrate this VM on another HOST, without changing its SR CBT is immediatly disabled ? why ?? next run of backup it tries a delta, but "fall back to a full" (normal as CBT has been disabled...), and do a KEY point on the remote next run is a delta as expected does this mean if I do a rolling pool update or host maintenance that will move the all VMs around, all CBT will be disabled and I should expect a FALL BACK TO FULL on all my NBD+CBT enabled backup jobs ??! why disabling CBT on a change of HOST and no move of SR ?

    @olivierlambert Thanks. --rename isn't mentioned in the KB. If I don't see something in the next week or two, I might be able to test it in a lab and then propose an update via a github fork.

    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

    @olivierlambert The only thing I can think of from newer kernels is NFS options like nconnect=xx for hopefully more speed in the day to day range of duties. As of the pre-LTS, this still wasn't in 8.3. I haven't checked after LTS.

    @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...
