try creating two different virtual switch

 

by: nourbenPosted on 2009-09-01 at 06:02:15ID: 25231093

Where and how?

 

by: nourbenPosted on 2009-09-01 at 06:27:24ID: 25231303

I have WMware Server installed on the host (not ESX), and I don't see any virtual switch option.
I am not going to have more than 2 virtual machines on this host.
Is there a may to connect one virtual machine 1 to use one NIC 1 on the host and Virtual Machine 2 to use NIC 2 on the host?

 

by: sathishchowdhryPosted on 2009-09-01 at 06:30:13ID: 25231333

yes you can, go into virtual machine settings (the hosts have to be powered down for making changes to NIC's)

if there is an existing NIC, make sure you have the NIC which has the subnet you want the VM to communicate externally.

Make same changes for the other host as well

 

by: nourbenPosted on 2009-09-01 at 06:41:52ID: 25231456

If I shutdown the host, then everything is down host and virtual machines.

When I edit the virtual machine nic, I see only Bridge/HostOnly/NAT, I don't see anything that tells me using subnet on NIC1 or NIC2 on the host

 

by: za_mkhPosted on 2009-09-01 at 06:46:33ID: 25231498

You need to configure your virtual network settings for the vmware server first.

vmnet0 is normally the default 'bridge' network and is bound to the first active nic adaptor on your host computer.

So for your second guest, you need to configure vmnet1 (which is not configured by default) to be bridged to your second network card.

This link, although quite old, (still applies for vmware server 2.0) shows you how to configure virtual network settings for VMWare Server.
For vmware server 2, you need to click on start -> programs -> vmware server -> virtual network settings or configure virtual network settings to get to the same screen.

http://www.vmware.com/support/gsx3/doc/network_change_bridged_gsx.html

What you need to do is this:

vmnet0 -> bridged to nic 1

vmnet1 ->bridged to nic 2

Then for Each Virtual Machine, ensure that the vNic is bonded to the appropriate vmnet.

Hope this helps.

Let me be more specific:

Hosts has two NICs:
NIC / IP Address / Subnet Mask / Default Gateway
NIC1:10.26.6.10 / 255.255.255 / 10.26.6.1
NIC2: 10.26.14.12 / 255.255.255.255 / 10.26.14.1

VM1 has one NIC: 10.26.6.50 / 255.255.255/ 10.26.6.1

VM2 has one NIC: 10.26.14.52  255.255.255.255 / 10.26.14.1

Only Virtual Machine WM1 has network connectivity, not VM2

 

by: nourbenPosted on 2009-09-01 at 06:57:46ID: 25231601

za_mkh:, I will try it and let you know.

 

by: nourbenPosted on 2009-09-01 at 07:04:17ID: 25231664

za_mikh,

I got the first part, but how to ensure that the vNic is bonded to the appropriate vmnet on each virtual machine?

 

by: nourbenPosted on 2009-09-01 at 07:12:58ID: 25231755

Got it, it shows on the drop list when you add it, I need to test it after hours.

 

by: za_mkhPosted on 2009-09-01 at 08:19:49ID: 25232477

Cool ... I think you will not be dissappointed ... it should work!

BTW, I hope you just made a typing error, but hoping that your subnet mask for network 2 is 255.255.255.0 and not 255.255.255.255

Worked fine, thanks
