Hi, All, Can experts examine the settings above if they are problematic? Could Management Server, KVM host and VMs all sit in the same 192.168.0.0/24 network? I checked a lot but have no idea, all firewalls have been turned off but still the SSVM could not contact Management server and the outside. Thanks a lot!
