Please be gentle....I am a newbie to almost everything XCPNG and Linux... I got to this part of the guide located at https://blog.ataxya.net/add-xen-driver-to-ome-dell-open-manage-enterprise/ [image: 1782424915722-2026-06-25_17h00_34.png] ....and those links don't work for me. I'm sure I'm doing something wrong.

Evening @pierrebrunet My bad. I am now on commit b440f and the issue persist. I have written you a message with the link to the file. Regards, Marc

@yannsionneau Hi, is June still the target for the iso? Thanks

@niko thanks, that would help a ton!

mid 2026: you can't add a ipv6 address via XOA (XOA5) because the gui lacs the field for the v6 gateway-address XOA6 lacks feature to configure ips of the host the configuration of ipv6 (static) vie the "gui" on the host seems not be implemented yet (or i am missing something critical) command line configuration inside dom0 of the host is afaik not supported ? Some point looks like minor issues. it would be great to "address" pun intendet that as well

@Danp said: Smart Reboot option found on the host's Advanced tab does what you are asking Very nice!

Here is the log from when xen04 last crashed xen04-jun12-journalctl-crash-summary.txt

@Pilow pretty much

@olivierlambert said: I'm not sure it's a great idea, because even 64 hosts is huge in terms of VMs and fallout if you have a problem on your pool DB. Even if you drastically improve the current mechanism, the impact of a problem pool wide is far bigger with 64 hosts than 24 for example. It's more than purely tech, it's also a tech design/choice. Exactly, the failure domain just grows exponentially when going beyond a certain collective pool size. I was doing some more research and I found a few possible choices that Tesco may have moved too, but don't want to detract from this forum here.

@AlexanderK you could try to install perl-interpreter manually maybe? I happened to have a test host at hand that hasn't been updated since december, and the yum update went fine, perl interpreter was not installed before and yum update did install it on its own as a depency for openssl 3. Maybe others will have ideas as to why this would happen in your case.

@tuxen Doing some research, it doesn't look like the Xeon's I have are affected. But I'm willing to try the next time I need to reboot. Will report back after that.

Hello, Thanks for all !

@laszlobortel Hehe yeah, those are pretty old kernels. I'd say there's a good chance kernel upgrades will go a long way to alleviating the CPU hangs. I can't say it's exclusively a problem with lvmohba storage, that's just what we use because of our previous VMware infrastructure was block storage over fiber channel. We knew a physical infra overhaul wasn't in the cards for us for this migration so we stayed with our existing storage system. This bug bit us half way through the migration until we figured out upgrading the kernel generally fixed it.

@psafont Thanks for the quick response and clarification. I appreciate you opening a work item for this. Looking forward to seeing this improvement in a future release.

For people running XCP-ng, wanting to use NUT client to power down gracefully during longer power outages, it could be interesting to note that Unifi now has two very affordable UPS models that feature a built in NUT server. So no need to run your own NUT server.
