    • Logged-in User: in the Sessions tab should be filled if a user is logged in.
    • All IPs (IPv4 and IPv6) in the Network Interfaces tab in the Guest Agent Data section for each interface.
  • Verification via on the VDSM side:
    vdsClient -s 0 getVmStats <VM UUID>
    
    • Reported fields are non-empty:
      • guestFQDN
      • netIfaces
      • disksUsage
      • memoryStats
      • guestName
