    That would explain things, and also why my latest test using AlmaLinux 10 also failed in the exact same way that Rocky Linux 10 did. I just wish I read this reply 12 hrs ago Think I'll give this stuff a go on v9 of Rocky Linux and AlmaLinux to check things are working, which I imagine will work fine. I've just confirmed the EPEL version running on AlmaLinux 10 at the time of writing this comment is indeed v 10.1 via the command; sudo yum repoinfo epel @dknight-bg What is the best way to keep track of this stuff proactively, i.e. What would I need to look at so that I could have determined what you have commented myself?

    @dinhngtu Thanks. We plan to migrate all Windows VMs from the Citrix tools down the road and only have a handful of VMs running these so far so will maybe hold off until the next version. Have been running the Linux rust tools for over a year with zero issues..

    I often wondered what's the general purpose of that option. As I only have 1 - 2 socket servers, I always choose 1 socket with x cores (mostly 2 - 8, not exeeding 1 real CPU). Also for historic reasons: Sockets have been limited, but not cores. Does it generally make any difference on Xen side/backend? VM OS might handle it different due to NUMA optimizations.

    How to protect a VM and Disks from accidental exclusion

    @dfrizon said in How to protect a VM and Disks from accidental exclusion: @olivierlambert The idea is to block the VM and exclusion disks even by root itself, and make it possible only via command line in the console. That's why I started the post by mentioning the command... We dream of the day when MFA authentication will be required to delete a VM... How would you prevent the root account from taking action..... that is the absolute opposite permission set of root, as if there is an account with even more permissions than root. You can use permission sets and move your team who are deleting powered off VM's that are protected from accidental deletion into a group that doesn't have the permission to delete VMs, at the same time, remove their permissions from deleting items from your SR. I think that would solve your problem, and doesn't cause any logical permission issues like above.

    Question about migration when creating VM

    @olivierlambert Ideally XCP-ng (xapi) could add this to a queue, and wait for some time before cancelling the task because it took too long. This also needs some kind of feedback that can be given to the user / client, which I think currently is quite undercooked (how to report is waiting on other migrations to the same host when a client asks?). For the time I think XO being aware that it can retry the operation would be simpler, especially because it already has code to do it for other operations

    Right now, it's XO -> Netbox only. As soon as you want something bidirectional, the complexity is exponential. I'm not closed to the idea, but we need to carefully think about the how and what's really expected functionally speaking from our users

    It's not a trivial scenario indeed. Dom0 is a PV guest (in other words: a VM) on top of an hypervisor (Xen), on top of an hypervisor (HyperV). As you can see, more layers means more problems

    @AtaxyaNetwork said in Unbootable VHD backups: @Schmidty86 Try to detach the disk and reattach, it should be xvda in order to be bootable That's what I was thinking as well, but obviously something is off with this VM. @Schmidty86 is the old host still online? If so you might be able to perform a Live Migration or a replication job to copy it from the old host to the new.

    Hello, thank you for your reply @bogikornel @TrapoSAMA . Here are my processor specifications: Intel Xeon E5-1620 v2 (8) @ 3.691GHz. Unfortunately @Andrew , I have to use RHEL 10 on my server ^^ but thank you for providing the link. I will change my processor/server.

    I worked with ChatGPT on this for a bit. We have narrowed it down to an issue with the NFS Storage that I ship the backups to. "When you recreated storage and moved data back, OMV is technically exporting a different underlying filesystem object than before. NFS clients that had an old handle cached (your XCP-ng host) try to access it and get ESTALE. That explains the initial backup errors and why deleting/re-adding the SR is failing now." I had to remove the NFS storage from XCP-ng, then delete the NFS share from OMV, then add the NFS share back to OMV, and then add it back to XCP-ng. I probably could have resolved this with a reboot, but I didn't wanna. This issue is resolved now.

    As @Andrew said, your host itself is unhealthy, you might be able to disassemble the CPU and heatseat, clean it up and add some new paste to address the issue with the CPU overheating (if the paste is shot). As for the memory issue, run a memtest on the host and see what is reported.

    CPU speed is great to enhance all Xen operations (using grants for example). But tapdisk got a lot of room to be better outside that, thanks to multiqueue and so on. However, it's not clear if it's better to improve tapdisk or making something different. This is an active topic of reasearch.

    @acebmxer said in Windows Server not listening to radius port after vmware migration: After migrating our windows server that host our Duo Proxy manager having an issue. [info] Testing section 'radius_client' with configuration: [info] {'host': '192.168.20.16', 'pass_through_all': 'true', 'secret': '*****'} [error] Host 192.168.20.16 is not listening for RADIUS traffic on port 1812 [debug] Exception: [WinError 10054] An existing connection was forcibly closed by the remote host After the migration I did have to reset the IP address and I did install the Xen tools via windows update. Any suggestions? I am thinking I may have the same issue if i spin up the old vm as the vmware tools were removed which i think effected that nic as well.... On your VM that runs the Duo Auth Proxy service, check if the service is actually listening on the external IP or if its just listening on 127.0.0.1 If its just listening on 127.0.0.1 you can try to repair the Duo Auth Proxy service, take a snapshot before doing so. Also, if you're using encrypted passwords in your Duo Auth Proxy configuration you probably need to re-encrypt them, just a heads up, since I just had to do so after migrating one of ours. Edit: Do you have the "interface" option specified in your Duo Auth Proxy configuration?

    We have some sites with a single-host XCP-ng pool backed by a small UPS. We install nut directly in dom-0. I'm aware of the policy for adding anything to dom-0 but we believe this usecase fits in the recommendations (simple enough, no vast dependencies, marginal resources usage, no interference ...). With proper testing works pretty well. nut inside a dedicated RPi definitely makes sense for a site with multiple hosts backed by the same UPS.

    Hello, We tried the compression feature. You "can see" a benefit only if you have a shared storage. ( and again, the migration between 2 nodes is already very fast, we don't see major difference, but maybe a VM will a lot of ram ( >32GB ) can see a difference. If you don't have a shared storage ( like XOSTOR, NFS, ISCSI ), then you will not see any difference because there is a limitation of 30MB/s-40MB/s ( see here: https://xcp-ng.org/forum/topic/9389/backup-migration-performance ) Best regards,
