    Q
    @ThierryEscande are you able to provide the beta code to @redorangefreak or me? I'm on their team and we are also seeing issues when attempting to use the RAID card at the XCP-ng level as the backing for a local storage repository. No VDIs can be created on it (workaround attempt).

    @WillEndure said in Beginner advice - coming from Debian: @DustinB @DustinB said in Beginner advice - coming from Debian: Why are you keen on keeping raw XEN on Debian? Not committed to the idea - its just what I currently have and invested a bit of time into setting it up and understanding it since before XCP-ng was around. Time is a factor too because you can waste a lot of it setting stuff like this up! But overall yes, I should probably move over to XCP-ng for my host. Got it, sunk-cost fallacy.

    If the machines are on the same pool no problem. If they are not, you need to export the template and import it in the other pool.

    @tjkreidl We don't need performance, but we do need to test how XCP-ng pools, networking, migration, live migration, backup, import from VMware and so on work. It's just a playground where we can have relatively many XCP-ng hosts, but it's not about performance, it's about efficiency and low requirements, because it's just a playground where we learn, validate how things work, and prepare the process for the final migration from VMware to XCP-ng. We originally had two R630s ready for this, then 4, but that would have been unnecessary, given the power consumption, to have physical hypervisors, so in the end we decided to virtualize it all. Well, on ESXi it's because XCP-ng works seamlessly there in nested virtualization.

    @Bambos A timeout error means that the host did not reply in the expected delay, which, if I'm remembering correctly is 5 minutes. I suspect a problem on your host but we will take a look further on your support ticket.

    @techknowbabble said in GRUB waits for confirmation: What did finally work was re-installing with the 'no serial' option and everything seems to be working as expected now. I only have a handful of XCP-NG installations under my belt but I wonder if this is a known bug or if anyone else has had a similar experience. It's not something I've ever seen before and I've done quite a few installations but I can think of some possibilities as to why something like that might fix the problem. My best guess is that there's something built into, connected to, or otherwise in your system that looks like a serial port (maybe even a real serial port) that spits out a character or two into the system at boot time, confusing GRUB and stopping the normal boot process. The bad KVM I mentioned before was doing something like that, throwing a bogus keypress into the system at boot time.

    @plaidypus Ah gotcha, this makes sense. I second scaling out instead of up. If you're getting new hosts, I'd also keep in mind newer CPUs do have much higher per core performance (not sure what your current stuff is), so you also might be able to get away with less vCPUs and lower likelihood of NUMA spanning. Either way though I think scaling out is the better direction to go.

    @R2rho yeah, there are Supermicro systems with AM5 which can handle a decent amount of load, like based on the h13sae-mf, like: https://www.supermicro.com/de/products/system/mainstream/1u/as-1015a-mt (with less depth) Seem to be stable, but we have a small issue regarding onboard graphics ATM: https://xcp-ng.org/forum/topic/9976/black-screen-after-install-on-supermicro-h13sae-mf-with-ryzen-9950x/3?_=1734419502978

    Thanks for letting us know, and I'm happy you have thing working nicely now. I think to mark this as resolved you need to convert your original post as a question, and it can then be marked as resolved. I actually cannot do it myself, I think only a few people have the permission to do it for others at Vates.
