@McHenry You can force halt the power state of each VM using vm-reset-powerstate. Then restart the VM on another host, assuming they have shared storage available on the other host.

@joeymorin That's correct. They need time to coalesce after snapshots change. Length of 1 is normal. They should clear up after a few minutes.

@olivierlambert I vote for HPE also! Thanks!

@MajorP93 I'm running with Node v24.11.0 now (on Debian 11 and 12). There have been some issues with older versions of 24, but to seems fine at this time.

@joeymorin I use @ronivay XenOrchestraInstallerUpdater script to help build my XO setups. It keeps the last three successful builds and has a rollback option.

@joeymorin @olivierlambert Same here error... updates have fixed it for me (same day).

I have updated the drivers for the Realtek RTL812x 2.5/5/10G cards. So far they are working correctly. There are a few minor issues that Realtek needs to fix (for the next version, they say). Also the new Realtek firmware has not been added to XCP (but it's not required).

The standard included 8125 driver for XCP 8.3 is not updated. To use the new driver install the new alt version of the 8125 driver. To support the 8126 install the required 8125 alt version first and then the new 8126 driver.

The 8127 driver is also available for the new 10GB chips (I just got a production PCIe card for testing). The first issue I see with this card is, it is only a PCIe x1 card, so for full performance you need PCIe 4.0... There are other 8127 chips that support x2 so they will better support PCIe 3.0.

Realtek will keep releasing new versions of the chips that will require updates to the drivers to function correctly. Even current versions of Linux needs updates to support the newer chips.

@kagbasi-ngc Alma Linux 10 release notes related to older v2 CPUs.

Try a x86_64_v2 boot ISO

@stormi Update (to the update) installed and running. Buggy Windows 2025 boots now with QEMU update.

@stormi Pool source SR is NFS. Destination has local EXT4. It's only around 70 VMs.

@stormi After pool update, XO Continuous Replication times dropped by 50%. Before, the hourly CR took about 14-15 minutes, after the update it takes about 7-8 minutes now. Most of the CR time is spent on setup of the VM for transfer, not the actual data transfer bandwidth. Normal delta backup times did not change (data transfer limited). No change/update in XO/hardware/network, just this XCP update.

@dinhngtu Correct! I was in /etc/ which has a default directory.

@stormi Running.... but...

#  secureboot-certs install
Traceback (most recent call last):

Also, can this update also include the fixvwc qemu Windows crash fix?

@dinhngtu Same results with the updated qemu-4.2.1-5.2.12.2~fixvwc2.1.xcpng8.3.x86_64. The Win2025 VM (without Xen tools) fails to boot correctly using stock XCP 8.3 but starts correctly with the fixvwc patch. (no actual performance or other testing done).

@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.

@olivierlambert @McHenry I have a similar setup... 5 host main pool (N+2) with TrueNAS NFS and a single on-site CR host (stand alone with local RAID storage) that is updated hourly from the main pool. There is also an on-site backup (for quick restore) and an off-site backup to wasabi S3 (nightly).

While CR is not a traditional backup it does allow for a quick restart of a damaged or lost VM. As my CR host is on-site it can share the same network and I can just start a VM immediately and then copy it back to the main pool. The CR also acts a secondary pool where some import redundant VMs run (ie DNS, another XO, etc). These secondary VMs are CR backed up to the main pool. If the main pool were to totally fail then VMs could be started on the CR host (with restricted resources).

S3 backups allow for a long term incremental historical storage but it takes longer to restore a large VM (but you can pick a point in time to restore from).

CR off-site is great DR option, but remember CR is not a true backup, it's just a recent copy...

@flakpyro I see the same issue.

@dinhngtu Win10 on XCP 8.3 with E5-2600v2 works just fine for me...

@florent It seems the Type: delta display during Backup fell back to a full may just be a display issue as it does seem to run a full copy.
