So if i set VMs to Best-effort or disabled for HA i get not enough memory. @pkgw Do you have Twinstore configured and/or HA enabled? If no I will continue my issues at the twinstore post. If i set to restart i get this.... host.setMaintenanceMode { "id": "35233210-4e37-4703-9bf6-9e8a9c24df9f", "maintenance": true } { "code": "HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN", "params": [], "call": { "duration": 5, "method": "host.disable", "params": [ "* session id *", "OpaqueRef:d9bd976f-445c-8244-1b56-879f446efc12" ] }, "message": "HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN()", "name": "XapiError", "stack": "XapiError: HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN() at XapiError.wrap (file:///opt/xen-orchestra/packages/xen-api/_XapiError.mjs:16:12) at file:///opt/xen-orchestra/packages/xen-api/transports/json-rpc.mjs:38:21 at runNextTicks (node:internal/process/task_queues:65:5) at processImmediate (node:internal/timers:472:9)" }

Great! I think this is really the best possible approach to make it clean

Hello. Thank you for your input. I am aware, that this is more of a warning message, than a error. I´m just trying to figure out, what is my best way to go here. My plan was: Setup a repljob for the vm in a lets say hourly interval On the day of the migration, shutdown the vm and start the last replication manually Disable the cr job Start the replicated vm on the new pool, check it and if all is ok, use it as new vm, otherwise start the old vm. The documentation says "If you want to start a VM on your destination host without breaking the CR jobs". Tbh i dont care about breaking the job. If everything works fine, i dont need it anymore, if not, i can setup a new job pretty fast. I was just wondering, if the new vm will stay in "blocked mode" for ever. Kind regards

@florent said: where does this disk comes from From my Redhat 10 @florent said: if you have access to your SR from the outside, you can also put the qcow2 file directly I create a VM to be a NFS to access the 3 HDs, the qcow disks are on the Redhat 10 that I was trying to import from. Do you mean I put the qcow disks on one of the HDs and access them when I create a VM?

@dthenot said: you will also likely need to give the host-uuid of the host the disk is on Thanks, and I'm assuming this UUID or Machine ID from: [14:45 xcp-kbbn NAS]# dmidecode --type SYSTEM # dmidecode 3.0 Getting SMBIOS data from sysfs.

@johnnezero The full HTML versions will render much better. The PDF conversion is less than perfect. iIll try to get those uploaded, as well.

Hi! I think what you're seeing may be stale entries in the XAPI database, ghost records that can survive upgrades or host reconfigurations. From what I've read, xe vm-destroy uuid=<vm-uuid> removes the record without touching any storage, which seems like what you need here; the xe CLI reference confirms storage is left intact. I think you can get the UUID first with xe vm-list name-label="Before Ubuntu Update" (replacing the name with whichever one you're after). I'm not entirely sure why xsconsole would show them but XO wouldn't, so if the VMs don't turn up in xe vm-list, it might be worth a mention to Team-XAPI-Network, they'll know the right way to dig into XAPI state.

@poddingue there is a notion of appliance too (group of VMs) https://docs.xcp-ng.org/appendix/cli_reference/#appliance-commands where you can start/stop a group of VMs, never tried it, doesn't seem to have a boot order in the vAPP neither

@bvivi57 xo do check license if you have xostor installed, since it need some magic to work at a lot of steps ( like the rolling pool updates) this is the expected behavior with a manually installed xostor ( cc @julienxovates for information )

@julienXOvates Got it. I didn't get a chance to work on this over the weekend, so sometime this week, I'll just bounce the host and see if it comes back. Right now, while I can SSH into it, the admin console appears to be frozen and unresponsive (over iLO).

@delacosta456 said: the pool host maximum limit is 3200% right right

@dinhngtu Thanks for the fast response, as always.

@gregbinsd let us know. If you do use my script. It pulls nodejs from NodeSource so it may not install the latest 24.15.0 tls. If you specific 24.15.0 it will install that version. If you need to change node version with my script use the rebuild option.

@Andrew Yeah but XOA is still using it hence my interest in aligning my XO-CE instance with XOA as close as possible.

Hello @tsukraw , normally your client should be able to bind the new license on their XOA. BTW, you talk about binding the license to a pool but an XOA license is bound to an XOA. I suggest your customer open a support ticket so we can help them with that issue.

While I was updating all the pools, a micro-update for 5 packages was released again. They come out every week now. Same issue with basic migration. Now it impossible.

Ping @Team-XO-Backend

@dinhngtu Yeah, I suspected that as well. So I inspected the SR and it showed connected to both hosts (at least in the XO UI - I didn't drop to the CLI to really confirm). By altering my workflow a bit and slowing down, I seem to have found the right "sweet spot" of delay and the issue hasn't resurfaced. Here's what I'm doing now, when I need to revert the snapshots of all three VMs: In the XO VM list, I select the three VMs and power them off at the same time. I then start with VM1 and eject the ISO, VM2 and eject the ISO, then VM3 and eject the ISO. By the time I circle back to VM1 for the next step, about 10-15 secs have elapsed. I then start with VM1 and revert the snapshot, and repeat the same on VM2 and VM3. By the time I circle back to VM1 for the next step, another 10-15 secs have elapsed. I re-attach the ISO to all three VMs in sequence. Another 10-15 secs elapse. I then start with VM1 and power all three VMs sequentially. The entire workflow takes about 30-45 secs, and I'm finding that by doing this, the issue hasn't resurfaced.
