XCP-ng 8.3 public alpha 🚀

olivierlambert

@cocoon VM actions are already planned (next step after the graphs, so maybe before 2023, but there's very little time now )

About ublock, I don't remember having issues with it, but obviously, we'll test (also, on the longer run, if the "online version" will fail to load, we'll fallback to an locally "older" installed version.

In that Browser I have even more blockers like AdNauseam + uBlock + NoScript, but the problem can be the same, just to remember that Browsers might have blocking utils in it if there is a problem for someone.

olivierlambert

But that's weird that Adblockers will block our domain, which is harmless and without any spam How could we explain it's "flagged"?

I can't explain it, just had seen the error
and here it seems to have happened, too:

Might worth a contact to the plugin authors to put it in a authorized list (or avoid to put it in a block list)

Is this release technically the point where XCP-ng starts to veer off more from the XS source as to my understanding they're already keeping some parts out of public repos nowdays?

It'd be interesting to see newer Xen for example in the future and the SMAPIv3!

olivierlambert

We can't answer since it's not only on us. But on our side, we have more knowledge and more capabilities than previously to make our own moves. However, we want to keep our "upstream first" philosophy and convince XS to stay close to us. That's why we spend some times to get decent pull requests and some patience to get them merged

We truly hope to share a common future where we wouldn't have to work twice on the same problems, but instead share our man power to be more efficient together. The rest is on XS team

Also, as said before, in increasing order of complexity:

Get a more recent Xen version
Get a more recent Linux kernel version
Get a more recent platform (beyond CentOS 7)

Hi Everyone,

I was wondering if this is a bug or if it is something specific to my setup. But.. I just noticed that a 'rescan' seems to be happening on my lab server every 30 seconds..

I noticed this because I was making a new template for XOCE and was deleting snapshots (viewing the /var/log/SMlog to wait until the coalescing was complete) and noticed that this was happening.

I will include the log file for viewing.. The log file is trimmed from 0730 -> present so it would fit in the posting limits.. But this was happening from the begging of the rotated logfile..

This is normal Adding @ronan-a in the loop to get a confirmation that SMAPIv1 is scanning every 30 secs.

@Anonabhar Could you upload the other logs (xensource.log, daemon.log, etc)? There is no valid reason to have a call to cleanup.py (not a SR scan) every 30s if there is nothing to coalesce.

Anonabhar

@ronan-a Sure.. I would be happy to... I just had to append a .txt to the end of the file in order to upload it.. Please remove .txt and decompress

So I read about the 'VM snapshot with disk exclusion' feature.

Is this supported at the XAPI level now? If so, how would one go about using it?

Regards

@Fungusware Hi!

Yes this feature is supported at XAPI level, the VM.snapshot method now has a ignore_vdis field which is a list of VDI ref to not include in the snapshot.
This also available through xe:

xe vm-snapshot vm=... ignore-vdi-uuids=uuid1,uuid2...

Regards

olivierlambert

@Fungusware Yes, @BenjiReis spent some time to make that contribution to XAPI upstream, see https://github.com/xapi-project/xen-api/pull/4563

benjamreis opened this pull request in xapi-project/xen-api

closed Add `ignore_vdis` to `VM.snapshot` method #4563

olivierlambert

Note: this is already implemented in Xen Orchestra since a while (by default we try to ignore the [NOBAK] disk if XAPI is able to do it, which is now the case for 8.3)

Fungusware

@BenjiReis Thanks for the info.

I'll see if I can support into the SDK also, at least for .NET anyway.

What is current status? What is the rough expectation of next alpha/beta release

olivierlambert

What kind of status are you expecting?

Fungusware

@olivierlambert Yes, I had been doing this also for quite some time. It was certainly one of the most requested features. It also felt a bit 'brute force' to me so would be nice to use it built in.

Anonabhar

@olivierlambert Well.. I have been doing the occasional "yum update" with no new problems. Everything is working great, but I still have that re-scanning of the FS every 30 seconds.. Not impacting anything but just a little weird...
