VMware Virtual Network Doubt !!!

your_shadow03 · 06-19-2009, 01:06 AM

I have been reading topic regarding Virtual Network and Come across thsi passage.

Code:

A virtual network is a network of virtual machines running on a single physical machine that are connected logically to each other so that they can send data to and receive data from each other. Virtual machines can be connected to the virtual networks that you
create in the procedure to add a network. Each virtual network is serviced by a single virtual switch. A virtual network can be connected to a physical network by associating one or more physical Ethernet adapters, also referred to as uplink adapters, with the virtual network’s virtual switch.

And then Line which really confused me

Code:

If no uplink adapters are associated with the virtual switch, all traffic on the virtual network is confined within the physical host machine. If one or more uplink adapters are associated with the virtual switch, virtual machines
connected to that virtual network can also access the physical networks connected to the uplink adapters.

What does it really mean?

I see a question. What's your doubt?

And to answer your question (I didn't find either
of the statements confusing):

If you have a real (physical) network adapter on
the computer that runs the host operating system
the VMs can get access to the physical network.

If you don't have a NIC the VM guest(s) can still
talk to each other and the host.

hi

i am having trouble with virtual n/w.

i have host system with 2 nic.(both on same subnet) network is 192.168.1.0

i created 3 virtual machines , 1 win , 1 suse and 1 redhat. i connected all this 3 virtual machines on vmnet2. which is subnet 192.168.5.0 .

all VMs are given static ip adress.dhcp is not active for that subnet

i just want guest only network connection and communican between all guest VMs . i do not want any thing connected to outside network.

but whenever i start my all 3 virtual machines -- only 2 of them can talk each other. 3rd one not able to comunicate even though its network services are up.

not conneting host can be any one which started last.

would u pls help me on this ?
