Feature pages are design documents that developers have created while collaborating on oVirt.

Most of them are outdated, but provide historical design context.

They are not user documentation and should not be treated as such.

Documentation is available here.

Verification

  • Follow the installation instructions above to install the guest agent
  • After about 15-30 seconds the Web Admin Portal entry for the VM should show:
    • the IPv4 Addresses of the VM in the grid
    • the FQDN of the VM in the grid
    • kernel package and the ovirt-guest-agent-common package in the application list
    • The FQDN in the general tab
    • 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
      • appsList
      • guestOs
      • username
      • guestIPs (if there are IPv4 addresses)

Note: The VM UUID can be found on the Admin Portal in the General tab for the VM

Note: The FQDN value is only only shown if the FQDN is not empty, not localhost and not localhost.localdomain
