RE: Remove a VM without Destroying the Disk
@JSylvia007 If you made the backup with a tool like XO / XOA then the backups should be unaffected. So long as they were proper backups and not just snapshots ! LOL
If you are worried, just do a restore before you delete the original VM. It will have the date appended to the end of the VM name, so it will not overwrite the existing VM..

CleanVm incorrect backup size in metadata
Hi all,
I keep seeing this weird error in the logs when my incremental backups run every night. It dosent appear to be causing a problem, but it is beginning to drive me a bit mental.
The backups complete without error, but the below is in my logs when I look through them.
I am using:
Any idea what this might be or how can I clear them. I have about 40 VM's that are showing this problem LOL

RE: Mellanox ConnectX-3 - Card not working
@Pyroteq I have seen others mention that its a lack of physical resources being allocated to the card.
As far as the firmware.. I think fw-ConnectX3-rel-2_42 is the latest for that series of card.

RE: Mellanox ConnectX-3 - Card not working
@Pyroteq Just as a point of reference, I use Mellanox ConnectX-3 cards all the time in my home lab for 40G Ethernet connection to my SAN. No problems with them at all. But as everyone has mentioned before, be careful of the firmware and model.. Some of the cards will only work in IB mode and others can work in IB or ETH mode.

RE: XCP-ng 8.3 beta 🚀
So I got a weird one. I have installed the latest XCP 8.3 updates and rebooted my server. All the VM's I had on my test server worked perfectly fine except for a single Debian 9 VM that would start booting and then "power off" just as the kernel started to spit stuff on the display.
I banged around with it for a while and what I found is its a kernel crash somewhere when SMP is initialized. If I only give a single vProc to the VM, it boots normally and all works fine.
At this point, its not causing me any more problems because I jsut rebuilt the VM on something more modern (Rocky 9)
I have perserved this VM if the dev's would like to get more debugging information or wish to try anything. I can also capture the logs if its of interest.

RE: XCP-ng 8.3 beta 🚀
@ravenet This worries me because I use the Connectx-3 cards in my setup. I wonder if I am going to run into the same problem or is it only a Connectx-4 problem.

RE: EOL: XCP-ng Center has come to an end (New Maintainer!)
@michael-manley Lovely! If you need beta testers, let me know... I use XCP-ng Center quite a bit and would not like to see it die either.

RE: XCP-ng 8.3 beta 🚀
Hi All,
Let me first say that I am using 8.3 Beta in my home lab and I quite like it. Seems stable and all is good in the world so far..
But I was wondering something. If 8.3 is not going to be a LTR, is there any point in upgrading my production stacks to it or should I just wait for 8.4 (I presume that is what will be the LTR).
I am assuming that if you needed some latest and greatest bleeding feature (maybe TPM?) then you should go 8.3?
I just dont want to go through the trouble of upgrading everything to 8.3 and then 6 months later having to do it again for 8.4
Kind Regards,

Any reason to not use NBD?
Hi Everyone,
I was wondering if anyone could offer some insight or advice. I have recently turned on "Use NBD Protocol" option for my local backups and CR backups between various DC's.
I must say that I am very impressed with this option. Using a concurrency of 1, the conventional backups give me a 300Mb/s throughput between Data Centres and with NBD enabled, I get roughly 790Mb/s (over a 1Gb line). So.. YEA!!
I have also noticed that if I re-dimension a VDI, it dosent trash the entire backup, but seems to understand that the VDI had expanded and writes the new data in the current backup, so again.. YEA!!
But I was wondering.. Is there any reason to not use NBD? Having the option to enable or disable almost makes me feel as if there could be a potential downside that I am unaware of.
Thanks in advance,
