    @idar21 @idar21 said in Xen Orchestra 5.110 V2V not working: Don't intend to bump in but the new migration tool isn't working as per the release notes. I had similar issues, there is no warm migration. My testing against esxi v7, resulted in: .Abrupt power off of source VM on esxi. .VM disks start copying. I can see disk copy progress in tasks. .Migration tasks fails but multiple disks of the source VM keeps on copying. .when all the disks are copied, there is no VM with the name available in xcp. .All disks are labeled orphaned under health in xo. .Where is the pause/resume function as stated in the release notes. I don't think the tool has been tested properly. The only difference from older migration tool to this one is progress of disk copying. Otherwise nothing new. The old tool could only do cold migrations and had issues with vms with multiple disks. The new can also only do cold migrations and still has issues with multiple disks migrations. First, I would like to say again that latest can be fresh, and that we know that we ask for our users to be more inventive with latest, in exchange for faster features. Even more for users from source. The documentation is still in the work, and will be ready for sure before this reach "xoa stable". The resume part don't have a dedicated interface : you do a first migration without enabling the "stop source", and then, later you launch the same migration with stop source enabled ( or VM stopped ) and it will reuse the already transfered data if the prerequisites are validated. Then debugging an issue with migration is quite complex, since it's involve multiple systems, and we won't have any access, nor control on the vmware part. It's even harder without a tunnel. I will need you to look at your journalctl and check for errors during migration . Also are the failing disks sharing some specific configuration? what storage do they uses ? Is there something relevant on the xcp side ?

    @olivierlambert Thank's. Is it just a lack of memory for my Dom0 ? What memory size do you recommend ? This is my production environment, so I'll have to wait before I can do that.

    @bleader just checked the Excel assessment file I got from the security team. They used Crowdstrike (sensor is not installed on xcp-ng hosts). The funny thing is, the asset that it reports as vulnerable is the VM that is running XOA (official image provided by XCP-NG). It is deployed recently, so everything is up-to-date, but even then I don't understand how it reports the XOA VM as the one containing the vulnerabilities.

    XCP-ng on a laptop - turning off the monitor

    @abudef I ran into the same thing on a dell latitude 5411, but I eventually found a workaround. In the BIOS under System Configuration there was an option called Unobtrusive Mode, and when enabled, a specific key combination will turn off the display and speakers, independent of the OS. The same key combination will then turn them back on when needed. While an automatic feature would be preferable, the manual option meets my needs since it would be rare to need to use the laptop screen. The one downside for me is that if power is lost long enough that the battery drains, the screen will need manual intervention after power is restored - the BIOS will turn the machine back on when it receives power, but won't put the screen back in its previous state. I put a sticker on the laptop with the key combination so I will remember it when needed.

    @sushant-diwakar I think you misunderstood @olivierlambert as he was referring to the support ticket that you opened with Vates, which is still open and awaiting a response from you. I restored the forum thread that you deleted because it contains information that is pertinent to this discussion. I'm leaving this topic separate for now, but IMO there really was no valid reason to start this new thread instead of continuing the prior one.

    @ImThatFluffy said in Issues with PCIE Passthrough: @john-c Yea im not sure, it was either an issue with the way I had Debian setup or compatibility things booted up Ubuntu 22.04LTS with the HWE kernel and it worked perfectly. Well if you are using Ubuntu Linux 22.04.1 LTS or one of the later point releases then it would be using a Linux Kernel version 6.1 or later, when its a HWE kernel. So any bugs from earlier versions of the kernel would have been fixed, also the Intel ARC graphics hardware would have been released during one of the point releases. On the Debian Linux front a distribution version earlier than version 12.0 would have been unlikely to have complete properly functioning support, due to that release being the first one with the Linux kernel version of 6.1 or later.

    @DustinB said in Imbedded Docker: Has anyone else done this, and can provide benefits or faults in doing so, besides the obvious that this isn't officially supported? I am actually going through the process of trying this right now, and am having significant difficulties with the xscontainer-prepare-vm piece - it doesn't work. So far, I have built a Docker VM, made sure all prerequisites are in there, and then run this script. It does insert an ssh-rsa key into my user's authorized_keys file, but the public key it inserts doesn't actually work. The host is not able to ssh into the VM due to the certificate not matching and requires a password, which does not work because it can't pass the VM check. Has anyone else seen this behaviour before?

    I've got passthrough to work a number of times without issue, the only thing I had to make sure of was that all devices related to the GPU were passed through completely. Are you following the docs step by step? I have a Ubuntu VM running with a 2060 passed through right now, works flawlessly and even survived a power loss on the host.

    @ajpri1998 I agree in regards to XOA getting damaged somehow, so that makes sense. I think my question here to OP was more about why they're concerned with it if they already have XOA. Normally if something happens to XOA though you'd SSH into the XCP-ng host and figure it out from there (which also means XO Lite could be enabled). Not criticizing at all, just was curious about the use case here in specific since it's being evaluated for enterprise use.

    As a general rule, you MUST keep all your hosts up to date. If you update normally, you will be on a 8.2.1

    @Danp said in Patching and trying to Pool Hosts after they've been in production: Warm migration should work in this case because the VM is halted then restarted as part of the process. See here for more details. Sweet, I'll setup something small on the old host for testing and use the Warm Migration process.

    There's no issue to restore everything from scratch, as long as your backup repo (BR/remote) is available. For example, fresh XCP-ng install, deploy XO, connect to the BR and it will find all your previous backups. Then restore, that's it!

    Now we have 76 VMs running on a 3 host pool. Each server has 320 GB of RAM. Our scenario doesn't need big CPU resources so everything works fine.

    @wilsonqanda Yes, BIOS as well, assuming I am remembering right haha. If you just pick whatever is closest and go with it I doubt you'll run into issues, if you do just make a post here and I'm sure someone will be willing to help out or work on a new template or something.
