XCP-ng 7.5.0 final is here
Congratulations to the whole team for the release of the new version XCP-NG 7.5.
Well, technically everything will be announced officially tomorrow
Also, don't use it now, it's broken (my fault!)
Fixed, new ISO incoming!
@olivierlambert is the ISO link updated?
@stormi will tell you when it's up (with the new md5sum)
It's fixed at last! Same link as before, MD5SUM is
There was a bug that was my fault (wrong product name in configuration files), but not the one about the installation failure actually. That one was dormant and already potentially present in XenServer installation ISOs too. There was some RPM that needed /bin/uname in a preinstallation script but in that version of the ISO, it got installed before the coreutils package that contains /bin/uname, so the script would fail and the installer display an error message. I fixed it by adding
Requires(pre): coreutilsto the package like it should always have been.
Further explanation: how can that happen?
Actually, when a package A requires another package B, it does not guarantee that B gets installed before A. They can be installed in the same transaction and then the order is undefined unless other dependencies are taken into account. That's what happened here. If A really needs B to be present so that it can be used in pre- or post-installation scriptlets, then one must specify it explicitly:

Awesome! Thanks a lot for your work. Can the update now be done via yum or it's advised to use the standard upgrade procedure (from 7.4.1).
It can be done via yum but we still consider it safer to use the ISO (because that kind of installation has been tested for a longer time, because it creates a back-up in the back-up partition...).
We'll give the yum upgrade procedure in the announcement.
Nice! that was fast

@stormi Okay, crystal clear thanks.

Gonna install it from scratch on the 3 develop servers.
Used Rufus to install the ISO to USB.
Booted, upgraded pool master from 7.4.
Tried to migrate all running VMs from the 2nd host (server1) to the pool master (server2) to apply the upgrade to server1.
2 VMs wouldn't migrate. Forcibly shutdown, now they are stuck as "Starting VM on server2..." not completing.
1 VM can't start "The operation cannot be performed because the specified virtual disk could not be found."
Upgrading from Xenserver 7.3 to XCP-ng 7.4 was cleaner.
Double check your shared SR is connected on all host.
@olivierlambert It is. Reconnecting all the SRs was the first thing you're presented with after the upgrade. Even the local filesystem and DVD needed to be repaired.
After a reboot and a "PANIC on CPU 0", I did a cold shutdown. All VMs start now except the one that can't find the VDI, yet I can detach and reattach the VDI in XCP-ng Center.
that's… strange. Could it be a hardware issue? Panic on a CPU is not commong.
This post is deleted!
@olivierlambert The VDIs are over shared ISCSI on FreeNAS VDEVs. There are other VMs with VDIs on the same RAID10 LUN that are running fine.
It's actually 2 VDIs and I moved both (boot and swap) of the failed VM to an alternate RAID5 LUN and it made no difference.
Is there a log I should be looking in to see more detail?
SMlogabout this VDI error.
PANIC on CPU 0isn't a good news regarding your hardware.
