@planedrop Why does it make sense to keep copying a VDI if there's no migration? It's just wasting resources.

RE: Minisforum HM80 (Ryzen 7 4800u)
@TheRedHerring I have an HM90 that I use as a host and it worked with 8.2 out of the box except for the 2.5G NIC. I switched to 8.3 and everything worked out of the box.

RE: Migration task cancelled but still occurring?
@planedrop Yes, that is correct. The traffic eventually stopped. I just checked and there was an orphaned VDI on the local storage.
I'm assuming that the cancellation just stopped the VM from migrating but the VDI was still copied over in full, which seems a waste.

Migration task cancelled but still occurring?
I started to migrate one of my VMs from one host to another along with moving from shared to local storage on that host. After a few minutes I decided I didn't want to do that and I cancelled the migration task. I no longer see anything in the task view but I'm still seeing network and disk traffic that indicates that the migration is occurring.
How can I make sure the migration is truly cancelled? Do I need to do any manual SR cleanup?

RE: SR migration causes full backup on delta backup job
@olivierlambert I have a related question that I can't seem to find the answer to in the documentation.
If I migrate a VM from local storage on one host to another host but with shared storage, what path does it take? Does the first host send the disk directly to the shared storage and then the memory to the second host?

RE: [DEPRECATED] SMAPIv3 - Feedback & Bug reports
I read through the intro article but I'm still a bit unclear on how this will work. Right now I have local ext storage and nfs zfs storage. What would I have to do in order to use SMAPIv3?

RE: Air gapped VM console access via XO UI
@olivierlambert I have not. I looked at it last year but haven't checked on it since.
I just tried it now and I remember one of the reasons I haven't used it. The self signed certs give my browser fits and I have to open each host up in a new tab to accept them by IP.
The console UI seems to work the same in XO lite as in XO. There doesn't seem to be any way to copy and paste.

Air gapped VM console access via XO UI
I have several tasks which require me to test things without having network access. Therefore I can't do the usual remote desktop connection as recommended. XO has a console tab but it's unwieldy and doesn't work well for copy/paste.
Currently I use Proxmox as it allows me to easily start a VNC console connection into a VM with no network access. I know this can be done via the command line in XCPng but it's a one button operation in Proxmox.
Is it possible to have this functionality exposed in the XO UI?

RE: SR migration causes full backup on delta backup job
@olivierlambert Does this happen as one step or are there discrete stages? Is there a way to get more visibility into it?
Also, is the migration going directly from SR to SR or is it passing through XO?

SR migration causes full backup on delta backup job
I've noticed that whenever I migrate a VM disk from one SR to another that my nightly delta backup performs a full backup for that particular VM. Is this expected behavior and is there a way to prevent it from happening?

RE: Is my backup configuration sane? (plus a bonus delta backup question)
@olivierlambert Okay, when you say 3 snapshots, you mean number of jobs, not retention? I tend to think of snapshots in ZFS terms so that may be where the disconnect is coming from.
In my example, there would be enough retention of the nightly diff snapshots so that you could restore to any day during the week. Once the weekend full backup occurs the nightly wouldn't be as needed.
I think I might be conflating snapshot and backup. I'll need to double check my cluster, but thinking about it, each nightly snapshot could be overwritten as it would have been backed up to the SR.
-
RE: Is my backup configuration sane? (plus a bonus delta backup question)
@olivierlambert Interesting. So you don't recommend nightly incrementals with a weekly full as it would generate too many snapshots and could start seeing performance degradation?

RE: Imbedded Docker
@DustinB Typical developer. I'll spare you my rant on the topic.

RE: Imbedded Docker
@DustinB I generally avoid mucking about with the internals of any appliance that I install but it's pretty surprising how many people want to do so.
Part of what I was wondering in your case was why Docker instead of k8s, etc. That's why I wanted to know more details about the need you were trying to solve.
-
RE: Imbedded Docker
@DustinB Curious about the reasoning behind your plan for going with Docker.
I'm currently running a Docker VM being managed by Portainer but I'm working on migrating things to Swarm to allow for easier distribution of resources across my hosts.
I've been looking at using Ansible to handle the configuration, etc of the VMs. I looked briefly at the templating but wasn't sure how well it would handle my needs.
I was using the various DevOps posts on the blog to look at the path forward. https://xen-orchestra.com/blog/virtops3-ansible-with-xen-orchestra/

RE: New Rust Xen guest tools
@yann I can't recall, but does it kick out a notice about that like BSD does? If not, is that a possible addition?

RE: two separate process for backup?
@robyt Can you post a screenshot of where you see NBD? I don't see it anywhere in mine but I'm not sure if I'm looking at the right place.
I think you need to get things working first and then start trying to push the envelop. I would set it to 1 and see what your speeds look like. Then you can slowly increase the number of connections until you stop seeing speed increases and/or you see http connection timeouts.
I'll admit that I haven't been paying attention to the whole thread, but I'm not sure what more testing you feel you need in order to determine that the problem is your NAS. What is the goal you're attempting to achieve that you're concerned that different hardware wouldn't solve?
I'm not sure what your configuration is (if you've posted it already, my apologies), but posting your XCP-ng host(s) details, XO specs, QNAP specs, and what other duties, if any, the QNAP is performing, that would be helpful. They make some powerful models, but most of them don't have that much oomph and can really only do one, maybe two things at once. And this goes doubly so if you're using very large VM disks instead of network storage.
In my case I'm backing up to a fairly beefy TrueNAS running a 11z3 setup on a 10G network. My VMs are all configured with smallish disks and pull the majority of their data from the same NAS. My biggest bottleneck is that my XCP-ng hosts only have 2.5G NICs which is why I'm considering moving XO to something with 10G in order to support the fully bandwidth.

@DustinB What are you using for cloud sync?
is not a cloud sync, is a copy to a qnap connected via gigabit ethernet
You'll note that that was a reply to @DustinB who is using cloud sync, not you.

@robyt When you say 10/12 NBD, are you referring to the setting of NBD connections per disk? Or connexion as the UI says. How are you checking that NBD is being used?
Connexion in UI
What happens if you reduce the number? From my understanding your Qnap isn't all that powerful, so it sounds like you're overwhelming the poor thing. I'm using 1 per disk and seeing over 1Gbps speeds. My main limitation is the 2.5G connection to XO.
However, I will say that I'm not sure if I'm actually using NBD or not. I don't see anything in the UI to indicate whether it's being taken advantage of. I also have my backup concurrency set to 1 to avoid running multiple transfers through XO as the switching can eat into the overall bandwidth.
