@borzel Does this still work with current versions of the guest tools?

Depends a lot on what you have available. IMHO, I consider the system as disposable, since you can export the metadata, reinstall and import the metadata again. Or backup your VM, reinstall, restore. Or migrate out to another host, reinstall, re-migrate the VMs. So many possibilities, that all depends on your setup.

That's the right way to do it in the future I suppose, however if it's not done, I can suspect it was during early "Citrix times" and decided it wasn't easy to do with the SMAPIv1 structure. Hopefully, since SMAPIv3 is splitting the things in a better way, it might be easier to make it real

@poltushima There technically is no CentOS 9, only CentOS stream. CentOS died a premature death when they pulled support for version 8 in 2021. We moved all of our workloads to rocky Linux and haven't looked back. Stream is basically a rolling beta and not something I would use unless you're just mucking around with it.

Very cool ! Will a great move relying on a single entrypoint.

@rjt You can customize the hook timeout by adding this setting in your xo-server's config: [xapiOptions] # Timeout in milliseconds syncHookTimeout = 300e3 # 5 minutes

This is unconditional for a reason. The CSTATE errata in Nehalem are crippling - IIRC a core going in an out of a deep C state does not maintain cache coherency correctly, resulting in arbitrary memory corruption. You really do care about not hitting this errata, even on a test/hobby server.

@splastunov said in Host CPU Statistics: You can get it with such command That command doesn't give me the aggregate, it only gives me the CPU for Dom0. I'd like to get that aggregate number.

@jbamford So yes no dynamic memory there. Perhjaps an issue with the Citrix guest tools but never seen this reported.

Hi, If someone would build this, it should use Xen Orchestra API, as the central orchestrator, that would make most sense to do it that way But yes, if someone want to start working on this, we'll be happy to assist on the API part

As you can see, the first alpha was not released in September Another XCP-ng pre-release will be done with vTPM, since there's more progress on upstream side (Citrix). When is hard to tell since it's not our call for this component

We always try to work with Citrix ("XenServer" division now), to push things upstream and manage to get it merged.

@olivierlambert For now I am going to script it with 'xe vm-export" command. Also it would be good to be able to export to the server itself, instead of downloading to the client. My VMs are over 500Gigs

@reinvtv said in NFS nconnect support: As far as I understand it, this will give us multiple tcp streams over an LACP link, truely aggregating traffic on multiple interfaces. (Until now, you needed to use iSCSI multipathing for this, which isnt able to thin provision.). You're neigher right nor wrong: LACP is more complex than just bundling NICs and in many cases it will NOT give you any benefit. Why? Simple: For that you need to have NFS using multiple ports but stay with same MAC and IP, which means that your LACP balancing algo needs to be set (and support) L4. Many just go L2 or L3 (means they decide on MAC or IP-Address). As a quick search didn't answer me: If it even doesn't go that 'passive range' multiple port way: In typical environments it won't help you at all with LACP. One might correct my post.

@Andrew I didn't say "Xen" I said XenServer.

Hi, Xen isn't Linux. When you boot on XCP-ng, you boot on Xen first, then the "control domain" will boot first (aka Dom0, aka what you think is the host but it's not). This has to be implemented inside Xen, and I'm not sure that's the case. Let me ask around.

Thanks a lot for your answer. I installed it on the XCP-NG host, and it works, but I do not claim that it works without errors, since I did not check the logs.

Hi, This will be the case at some point, and it shouldn't be too difficult. We have the will to be able to provide a "cutting edge" version for people who want to play with fire
