Thanks for taking the time to report this bug an trying to make Ubuntu
better.

Is this the only relevant message you found in the syslog? Is this error
causing some unexpected behavior apart from this message in the syslog?
You mentioned the error in the log but did not mention what is the
impact of that, is this not allowing you to reboot the VM?

I am setting the libvirt task to Incomplete until you provide more
information, when you do that please set it back to New and we will take
a look again.

** Changed in: libvirt (Ubuntu)
       Status: New => Incomplete

  Steps:
  1. Power on SUT and install Ubuntu 22.04 LTS on VROC NVMe RAID 0 disk.
  2. Install KVM features and desktop GUI.
  3. Run "apt upgrade" to update packages.
  4. Create a namespace on BPS DIMM App Direct Not Interleaved mode.
  5. Run "virt-manager" then install Windows Server 2022 on the namespace.
  6. Reboot Guest OS and Host OS to check if there is any unexpected error in 
system logs. (=> failed, there are libvirtd errors in /var/log/syslog when 
booting into OS or powering on/off the virtual machine:
  libvirtd: internal error: A field data length violates the resource length 
boundary.
  libvirtd: message repeated 3 times: [internal error: A field data length 
violates the resource length boundary.] )

  Expected behaviors:
  There are no any unexpected errors in system logs.

  Current behaviors:
  There are libvirtd errors in /var/log/syslog when booting into OS or powering 
on/off the virtual machine:
  libvirtd: internal error: A field data length violates the resource length 
boundary.
  libvirtd: message repeated 3 times: [internal error: A field data length 
violates the resource length boundary.]
