    I am running NVIDIA P40s on a DELL R720/R730 and a NVIDIA A2000 12GB on a DELL Optiplex 9010 in my playlab. Getting the GPUs to be accessible for VMs was quite easy: shutdown the XCP-ng host, install the GPUs, start the host again, activate the GPU in the advanced settings of the host in the PCI Devices section (“Passthrough enabled”). The host will restart at this point after displaying a warning. That's it – the GPU can now be assigned to a VM in the VMs advanced settings. I do use the GPUs for AI workloads under Debian though, so your use case might vary.

    @bleader Hopefully the palm print on my forehead isn't visible from where you are sitting. Of course the interface needs an IP address. In my defense, normally for something like this, I wouldn't put it on the bonded interface with all the trunked VLAN's for guest traffic (we don't give that one an IP) and it would go on the other bonded interface that isn't trunked and does get an IP, but these are test hosts and I didn't set up the other bond, so it is pulling double duty. I was able to set the IP's and get SDN working. Thanks!

    @Greg_E i think protection is doing its job. do not delete. but in case of healthcheck, the process should bypass that for the restored VM thoughts @bastien-nollet @florent ?

    Kubernetes CCM for Xen Orchestra v1.0.0-rc.1 We’re shipping v1.0.0-rc.1, our first release candidate on the road to a stable 1.0.0! This RC is feature-complete and ready for real-world use. Please try it out and share any feedback—bugs, regressions, or usability notes—so we can polish the final release. Thank you for testing and helping us! https://github.com/vatesfr/xenorchestra-cloud-controller-manager/releases/tag/v1.0.0-rc.1 Golang SDK for Xen Orchestra v1.11.0 SDK v2: VM and Task services now match the latest REST API. Host service has been added for host data retrieval. Integration tests have also been strengthened to boost reliability. The v2 SDK is gradually becoming our main library for all the other DevOps tools (Kubernetes drivers, Terraform provider…). There are BREAKING CAHNGES in the v2 SDK, so please read the release notes carefully. Remember that the v2 SDK is a beta version and can be subject to significant changes. The current semantic versioning we use is mostly for the v1 SDK. When the v2 SDK becomes stable, the major version number will increase. https://github.com/vatesfr/xenorchestra-go-sdk/releases/tag/v1.11.0

    @julien-f Hmm, that's a bit disappointing that there isn't much you guys can do to help. No worries, I'll keep testing. My AD environment works fine, since the accounts in question are not locked and are being used daily. The only place they're failing is in XOCE or XOA. It's gotta be something with how the library is handling characters in either the username or the password. I'll keep testing until I can find a repeatable pattern. Thanks to both you and @olivierlambert for the help thus far.

    file restore on large backups ends in print_req_error: I/O error's

    @olivierlambert said in file restore on large backups ends in print_req_error: I/O error's: Yes, that sounds the next step to do Something is wrong during the mount phase. Also check you have enough RAM in your XOA. Ok, filesystem checks out - as far as I can see having: Done full restore of VM from the same Delta image. Booted VM, logged in and done 'tar cvf /dev/null *' of the filesystem I'm trying to restore from - which ran to completion without error. I upped the RAM for XOA from default 2GiB to 16GiB and re-tried - and same result. I can try yet more RAM if needs be but would hope 16GiB is more than enough? The console error on XOA is more detailed than my install- so don't know if this helps: blk_update_request: I/O error, dev loop0, sector 8912912 op 0x00:(READ) flags 0x80700 phys_seg 1 prio class 0 Looks to be the same issue, just reported differently. You also (on both systems) get kernel chatter about "tasked blocked" (understandable, as it is).

    Can't restore VM's from 'read-only' remote?

    @olivierlambert said in Can't restore VM's from 'read-only' remote?: A remote (now Backup repository) is meant to write backups into it. If you aren't able to write, then, sure, you can restore but you won't be able to backup anything. Yes, understand that - I'll have to re-test here, but I'm sure when it was 'read-only' - I couldn't restore anything from it, as nothing showed up in XO's "Backup / Restore' list of backups... The remote was mounted on two systems - hence why made R/O for one of them (this was just for testing restores).

    @Zevgeny Did you succeed to remove the protection with "xe vm-param-clear"? It didn't worked perfectly for me. Before I use xe vm-param-clear, I have the following: [18:28 xcpng02 ~]# xe vm-param-list uuid=37b7a201-eb45-b7de-5ce4-da25b1c7b547 | grep block blocked-operations (MRW): pause: true; hard_shutdown: true; (unknown operation): true; hard_reboot: true; clean_shutdown: true; suspend: true; clean_reboot: true [18:28 xcpng02 ~]# Now I try to clean: [18:28 xcpng02 ~]# xe vm-param-clear uuid=37b7a201-eb45-b7de-5ce4-da25b1c7b547 param-name=blocked-operations The value given is invalid field: blocked_operation value: (unknown operation) [18:28 xcpng02 ~]# After, "blocked-operations" looks like this: [18:28 xcpng02 ~]# xe vm-param-list uuid=37b7a201-eb45-b7de-5ce4-da25b1c7b547 | grep block blocked-operations (MRW): (unknown operation): true; hard_reboot: true; clean_shutdown: true; suspend: true; clean_reboot: true [18:30 xcpng02 ~]# In the GUI of XOA, the "Protect from accidental shutdown" is removed but not on the command line.

    I think this is important. When the issue appears the replicated VM that auto-starts has the [IMPORTING] prefix as in the image below. [image: 1689001402269-130e1c45-ad28-4b6c-a4d7-202b552ab723-image.png]

    @pdonias Hi, On Master, as of yesterday, I see this only when I am logged in using an IP address on the URL instead of the hostname. Either way it is SSL with trusted certificate. There are no console errors Browser is Microsoft Edge on Windows No difference in behaviour between incognito mode and normal. Yes I see all the VMs There is an improvement - now if I am creating a new VM only the selected network is reverting back to default when it refreshes, the other things like number of cores and ram is remaining when I set it, whereas previously these also were wiped back to default every 20 seconds or so. Thanks Alex

    Yeah for doing a fresh start it's easiest to just nuke the backup directory you were using and start over, have done it before and it's quick and easy vs trying to manually remove them all within XOA.

    [Solved] Last XOA from sources and backup with NFS (doesn't work because error in --options argument while mount)

    @ronivay, I resolved my problem with orchestra which did not want to make backup with NFS. Orchestra wrote errors like: Command failed with exit code 1: mount -o -t nfs 192.168.11.53:/backups/xo /run/xo-server/mounts/0e5e9511-8912-48d4-96ad-532979533332 mount: only root can use "--options" option In general, orchestra tried to use mount option "--options" but mount command rejected this option. When I mount my NFS-shares manually everything was ok - mount works, read-write too, umount also. I did simplest process. I removed at all "--options" from mount command. (As far as I understand, *BSD mount will not work without this option but my Ubuntu works). Background: xcp-ng server (centos 8.2) as NFS server ubuntu server 16.04 where orchestra is going to be placed Orchestra installed 10 days ago from sources according to https://xen-orchestra.com/docs/installation.html#from-the-sources I complete followed document before chapter "Installing dependencies". I made yarn Then, before "yarn build", I manually edited file: /opt/xen-orchestra/@xen-orchestra/fs/src/_mount.js at string 68 I replaced await this.#execa('mount', ['-o', options, '-t', type, device, realPath], { with await this.#execa('mount', ['-t', type, device, realPath], { I then proceeded to follow the instructions: yarn build a so on... Now "patched" orchestra fine makes any kind of backup with NFS. At least, I solved this problem. Yet another question appeared as backup works What kind of Backup should I use to make full copy which enough for restoring (Heaven forbid)? I tried simply "Backup". It SUCCESSFULLY (!) created several files with 56 kbytes (no giga, no mega but kilo). I suppose it abnormal. My VM has got 20 Gb of disk space and about one half is already used (ubuntu server, postgres etc). As far as I understand (https://xcp-ng.org/forum/topic/7034/backup-with-local-usb-hdd-attached-sr_operation_not_supported/5?_=1688120707451) my version of xcp-ng (8.2.1) does not support "Snapshots" with local disks. Now I copy imagine of my VM with cron as temporary option but may be there is some more correct backup option?

    @julien-f @julien-f All I have done is let ronivay's script do the builds daily on schedule if there is a new commit on the master branch. His script has not changed. There have been no new patches to the hosts. I don't have an explanation.
