@DustinB Hmm - just got done running mem86+ - 4 passes -- all 14 tests. No RAM errors. I wonder the what would cause this error? I'll probably just save config and reinstall. So strange.

@Danp UEFI

Thanks for engaging! In this thread I would say: Storage I need it to get ISO files uploaded without going native (CLI). Or in other words, the basic stuff you would expect of a web-interface to be able to launch working VM's.

@acebmxer Hello, We’re aware of the Backblaze rate limits and this isn’t the first time it’s been raised. We’ll be looking into this on the XO side, studying different options such as caching restore points to reduce API calls. Longer-term improvements, possibly tied to advanced XO6 dashboards, are more of a 2026 horizon. Thanks for bringing this up!

@Pilow did you try tcp?

@abudef Got it, the agent was not changed since the last version so the build number was not bumped. I'll keep that in mind for the next release.

@AtaxyaNetwork Did try to change those files and add the missing drivers, but couldn't get it to work with plugins. I think I will just have a look at you image when I have it and see what I am missing

Hi, Small side note: lately I’ve noticed that some posts look like they were generated by LLMs. This can actually make it harder for the community to help, because the text is often long, unclear, or missing the basic details we really need to assist. I’d really encourage everyone to write posts in their own words and share as much relevant information as possible. The real value of this community is people helping each other directly

On DOM0 (host xcp-ng) traffic is filtered by iptables. So iptables -L will show which ports are open. Everything else will be rejected by default. For testing, you can stop iptables. If that helps, add rules. Keep in mind that XCP-NG is based on CentOS. So you can easily find an answer on Google for any question.

@DustinB Guest tools simply don't support the system I'm running.

Sorry, I'm asking if I should be good deleting the snapshots

I would recommend Intel or Mellanox NICs, and generally avoid Broadcom due to sub-par drivers.

@KPS Unfortunate, no. I just replicate and avoid moving live VM on the same host, target for replication.

@PaulDCL [image: 1757633451167-9eb17eb5-9a99-4743-9df5-51edcc2b1847-image.png] This benchmark was taken inside the Windows Server VM on that iSCSI device. The iSCSI host is a QNAP NAS with Toshiba 18 TB drives configured in RAID-6. I think this is a decent speed for non-flash storage. Both devices are on a 10Gbit network. If you need more specific details, I'll be happy to help.

Hi, There is an issue and/or a PR (I don't remember where though) to have a specific extra file to manage user config without overwriting it. Until then, it will be overwritten after updates. @Team-XAPI-Network could provide the link to the issue (or PR?) and check to make it merged when possible

@mdavico said in Debian 9 virtual machine does not start in xcp-ng 8.3: Update: If I change the vCPU configuration to 1 socket with 4 cores per socket the VM starts correctly Interesring. First time I heard it had any effect at all on a VM.

We don't have any feedback on that, so I can't tell

It's not the first approach, you have KubeVirt for example.

Before the end of this month.
