Seen on the reference machine while a Windows VM held the RTX 4090:
berth vfio status 0000:01:00.0said "berthd unreachable" while berthd answered. With an address, the command skipped berthd along with nvidia-smi. Now only nvidia-smi is skipped.Proof:
TestVfioStatusWithAnAddressStillAsksBerthdfailed before the change (output included "berthd unreachable") and passes after.TestVfioStatusNamesTheVMNotAStaleReadingcovers the wording. Run live during the VM session, the new binary prints the VM state and the grantedvfio:galaxyhold. Full proof green.
