@stormi Microcode updated on affected Gen11 i7. Running normally.

@gduperrey I jumped in all the way by mistake... I updated a wrong host, so I just did them all. Older AMD, Intel E3/E5, NUC11, etc. So far, so good. Add/migrate/backup/etc VMs are working as usual. Good for guest tools too, but mine are mostly Debian 7-11. Stuff is as usual so far.

I agree and I'll say it again, Thanks! It's not just Linux/Xen stuff. It is XCP-ng and XO that make everything work as a cohesive vertical open-source solution (some nice buzz words). Thanks to the Vates team and community that have built and support it. I look forward to ongoing continuous improvement and innovation!

@bleader Installed and running.

@bleader Updates running on several old and new intel machines (including microcode update). Working fine so far. Rolling Pool Reboot is a helpful feature.

@bleader I installed it on a bunch of busy hosts. All are fine, but none used PCI passthrough. The Rolling Pool Reboot in XO was very helpful.

@dinhngtu On a quick test, the ISO boots and installs. When the VM boots from the HD it crashes (and on reboots).

Updating XCP 8.3 with qemu-4.2.1-5.2.12.2~fixvwc1.1.xcpng8.3.x86_64 solves the issue and the installed windows image boots correctly without any additional changes.

@abudef @olivierlambert @thomas-dkmt I agree. I read block the same way... how about disable or prevent. (French? empêcher)

@julien-f @olivierlambert

Thanks for the ability to delete XO task logs feature! (XO commit f6e6e)

@gduperrey Installed and running on Intel systems, and Zen3 system that sees the microcode update.

@rzr Updates installed everywhere (on top of the previous updates). Rolling pool reboot worked this time (with correct prep).

@poddingue Since setting NBD=1, I have not seen the problem.

SR is NFS on dual 40G ethernet with a TrueNAS scale 25.10 server using all NVMe SSD, so storage performance is as good as I can make it.

I'll have to enable NBD=2 again to see if it still happens and if I can find the relevant part of the logs. As this is a random problem I can't recreate it on a normal test environment.

@All-Ki Thanks for your work!

I found the first step. It's looking for the vendor as the whole name proliant dl360p gen8

Then I have a few working, and several that don't.

Works: Total Power, CPUs Temp, Fans Speed.

@olivierlambert With the new IPMI plugin for XO I was hoping to see support for HP servers. But at least it seems I can add it to my installation and then post my results.

I added "hp" as a vendor and all of the plugin settings (if you leave it blank there is an error when saving).

But I still see no sensor data for the hosts in XO.

Any thoughts on what I should add? check? do? to make it work?

@florent As a note, I'm using Debian as the base OS for XO. Other OS, like Ubuntu may have other name conflicts...

As for links, the dropdown box should show the link and it's destination). As a link, I don't think you need to "follow" it when selected (like a directory would), it's just a file. I did not check other non-standard files (like devices).

If I select a directory to restore then it would be good if the links are included. Both tar and zip do support links, so they should be restorable.

@florent Ubuntu LVM file restore is working! (commit 38931)

Now for another important issue I noticed with file restore (not directly LVM).

Symbolic links don't show up. They should be restorable alone, but more importantly you need to be able to see and follow them for directories.

For example. In Ubuntu, /bin is a link to /usr/bin. It is important to be able to click on /bin as a link to /usr/bin so files can be found in the backup. Another example is /vmlinuz that is a link to boot/vmlinuz-5.10.0-44-amd64. At worst the file restore should show a link (and it's destination), even if I can't restore the link. This is not just a LVM issue.

@florent LVM restore still failed for me (fix_flr commit b7230). Trying file restore from Ubuntu 22 VM (on S3 delta backup). Single VDI, 3 partitions (bios, uefi boot, LVM root). Accessing the LVM root.

@rzr Installed and running. Not expecting any issues because I'm not using SMB/CIFS, ice card, or CPU with affected microcode.

Rolling pool reboot failed me again... This time it got stuck evacuating a host with no VMs.

@bleader A note on the option screen VM restart required to use new value is good enough. No realtime/live change needed. I'm just looking for quick easy GUI option rather than XPC CLI.
