@stevewest15 My understanding is that being able to check CPU masks went away a long time ago and the pool master supposedly automatically deals with all the CPU masking now. If none of these are in production you have not much to lose.
I'd suggest trying it out with the three different hosts and see what happens. Worst case, it won't work.
Caveat: If in a pool and you eject a host, it will lose all the information on its local SR(s).
Also, the Gold 6132 is going to suffer some if it has to be downgraded to work with those lower-end machines. I would in general not advise making pools with hosts that have that wide a disparity in CPU age and capabilities.

Might those page fault entries indicate a memory error?

@chcnetconsulting Glad to hear and nice debugging work! Yes, the HA-Lizard folks are very responsive and I'm sure will have this taken care of in the next release.
I published an article originally on xenserver.org back in 2016 on tests and improvements to HA-Lizard I did in cooperation with the company, but alas, the chart with all the findings didn't translate properly when taken over by this site. I may have the original squirreled away somewhere.

@chcnetconsulting Are you running the latest version of HA-Lizard? They care very responsive to issues if you contact them. And, yes, see if you see anything odd in the logs. Also make sure you hosts are properly time-synched with each other.

@EddieCh08666741 Indeed. Run top and make sure you have adequate resources allocated for dom0 for both memory and CPU. There should be no swapping to speak of and the CPU should be nowhere close to 100% in use.

@jhansen Great news! Maybe the SR-IOV issue is driver-related - is there a newer driver available or perhaps some setting in the BIOS?

And, yes, I bet wiping all the old partitions made a big difference.

@tjkreidl
Although it's my test lab, I have a backup of everything. I'm something of a burned child with many years of bad experience.
Unfortunately it would take a few days to play everything back.
But I'll get a new SSD and give it a try.
But first thanks for the help, I'll write if it worked.
Regards Joerg

Sounds good, Joerg. Good luck!

@jhansen If you have the full metadata, I would think that's possible. What about any VM backups, custom network settings, etc.? Lots to make sure you have before anything that drastic.

Mayby you are on the right trace.
It is a Dell Server.
This time i will wipe the disk before installation.
As the Data is on other disk i will try to mount then afterwards.
Thanks

I am willing to bet you got bitten by the Dell utility partition disk issue. And, yes, best to wipe it out. Or delete it and redo one of the other partitions. But frankly, you will really want the new 36.5 GB total layout with the dual 18GB partitions, etc., that was mentioned above. You will want the right order of partitions to match what the XCP-ng installation wants to do at some point, but it should redo the layout I hope once you get rid of that extra Dell partition. Check out what I did in my article referenced above:
"The solution was simply to delete that sda1 partition altogether using fdisk and re-install. Deleting the partition can be performed live on the host prior to the installation process."

@jhansen Any old Linux distribution recovery-like boot disk should work, as long as you can get to the partitioning app.

@jhansen I'd suggest booting off some Linux rescue disk and just redoing all the partitions manually. I ran into an upgrade issue once on a Dell box because of some stupid little extra utility partition they had in there. See: http://xenserver.pl/author/tobias-kreidl
Look for "The (In)famous Dell Utility Partition."

@Gheppy Run "top" ans well as "iostat" during your backup to see if any saturation is taking place -- CPU or memory on dom0, queue and I/O throughput on the storage. I agree with @olivierlambert that a 2.4 GHz CPU is marginal in this day and age.

Do you have the use memory above 4G decoding disabled in the BIOS settings?

@Gheppy If you go over a VLAN and/or a priviate, non-routed network, why even introduce the overhead of SSL unless you are super paranoid about security?

@Berrick Run iostat and see if anything shows up as slow or saturated with your storage I/O.

@anturk What errors do you see in /var/log./SMlog related to this? Have you run ifconfig or netstat to look for network transmission errors? Is this a new setup and if so, are you sure the cables are of good quality? Is this a dedicated NIC or is it part of a VLAN?

@splastunov Hmmm, not sure that will work for long for a P4 or T4 without an NVIDIA license. At some point, it will likely throttle down to a maximum of 3 FPS after the grace period expires.

Then again, you might get lucky.

@splastunov My guess is that it's not going to be possible to do any customizing since the GPU configuration types are managed by the NVIDIA drivers and applications, which incorporate specific types associated with each GPU model. As newer releases appear, sometimes this will change (such as with the introduction of the "B" configurations some years ago).
About the only close equivalent to a "raw" designation for a VM would be to do a passthrough to that VM,but even then , you still are going to be restricted to defining some standard GPU type.
