Tonight i noticed our XOA memory usage was high today so i tried running xo-cli xo.clean as you suggested. It returned a status of "true" but unfortunately did not seem to make a difference in overall memory usage. [image: 1772944104119-50b98e75-8bb6-4a31-8529-33f003796d3d-image.jpeg]

@florent One last update. I reverted to Master branch (6699b) yesterday evening and the backup ran without issues overnight.

@TeddyAstie Thanks for the update. I do actually have a VBIOS for that GPU, but I wasn't entirely sure what to do with it - is there a process to inject it? I've found resources for Proxmox and others, but I really like XCP and equally I don't want to migrate my entire setup just for that. If it's really tricky then I'm not too worried about it, as I say the VM actually runs the cameras perfectly fine on CPU alone, it's negligible. Edit: Looks like this post might answer my question: https://github.com/xcp-ng/xcp/issues/786 "Even when specifying romfile and rombar properties on the xen-pci-passthrough device in QEMU, the ROM region is not mapped into guest memory." timemaster5 created this issue in xcp-ng/xcp open PCI ROM BAR not exposed to guest when using xen-pci-passthrough #786

502 is an answer coming from your S3, telling the server is having an issue. Adding @florent in the loop

I've had a lot of updates happening in the homelab. I've replaced the T620 with an R740, expanded my storage for both HDD and NVME pools. Also did a little min-maxing on the hardware to help separate traffic, decrease some latency and jitter for internet traffic and introducing IDS There are a lot of additions and modifications, but I guess the other big one is setting up a Dell Precision 5820 with XCP-NG as a studio and prototyping rig. Replaced Ansible with AWX, added some more VMs and migrated others but in all that I've updated the diagrams as well! Will say that XCP-NG offers up the flexibility and performance that I've needed so far. Would love to try out the XOSTOR storage at some point but will have to move around my entire setup haha.

I looked into the backup job and i forgot to enable a few settings when recreated the backup job. After renabling the below settings i reran the backup job. The vm in question did a full backup. All passed.

@AtaxyaNetwork Hello! I am on an XOA trial with no airgapping.

@florent I have tested in our dev environment backing up a 30GB VM, which compressed into 22GB and was uploaded in 739 parts of 40MB each. I will test a larger VM next week but I think this was successful test is already conclusive. Thank You

@hawkpro I believe it will be worse with continuous replication because your replica will be in a shut down state. When you decide to start it, you will have to shut down the original VM and start the replica. You will have a downtime during shut down and start up sequence. Downtime during VM migration is a necessity so there is nothing unexpected there. All types of migrations require a VM to be suspended for some time (usually seconds) during the switchover from one host or SR to the other host or SR. If you have extended downtimes of your VM migrations, then something is not quite right with your setup.

I am in the same situation as @vhaelan. same as in same iGPU (alderlake) passed-through, same output for those latest commands, same OS (Fedora CoreOS on latest Xcp-Ng stable). Tried current avenues suggested in this thread with no progress. It seems vhaelan has settled with CoreOS under Proxmox (which works!). He also mentioned it works in Debian under XCP-ng, though I haven't tested that myself. I would appreciate additional suggestions for troubleshooting to take this further, in case anyone has any other ideas.

All vms still on host 1 after setting Migration cooldown time to 0 this morning. Maybe bug or just ui bug. When set to 0 save config when you load the page the "Fill information" for Migration Cooldown setting is unchecked but 0 is still applied. If set to 1. and reload the box is check as expected.

@simonp I'm not sure which one as I can see 2 config.tom file. 1st is under "/root/.config/xo-server/" config.toml.txt 2nd is under "/opt/xo/xo-server/" config.toml2.txt Both config.toml attached. Thank you. Best regards, Azren

No worries, it happens! Glad you found the problem

@Greg_E Thanks, I've got another thread up and it's potentially being addressed!

@firefly because the underlying hardware that the VM has registered has likely changed, maybe substantially. A sysprep has the Windows system go through and validate what it's hardware is, it removes hardware specific drivers namely, but it does other stuff too.

And to really round this out, the MTBF for any of these is in the millions of hours (1.2-3M), that's a use time of 136.968 - 342.46 years respectively. Basically, if a drive dies, just replace it no matter what, but in the end the reliability of these drives is meant to outlast all of us. Unless you actually need some specific function provided in some form-factor or model, don't bother.

@DustinB doesn't it use the exact same mechanism? I have to find out.
