If you are new to vmware , do check Tarry's article hereto get some idea . Below i try to explain some of the errors while using the VMware for the first time. Note: You can also check VMware website and their docs for more details

I cant communicate between host and virtual machines
- Check your vmware network settings . In case of Bridge Connection, by default your host machine's physical network card (say eth0) is mapped with vmxnet 0(virtual network adapter) though you can change it.Virtual Machines communicate with the host machine using vmxnet0-eth0 interface.

I cant communicate between my Linux virtual machines
- Check your Linux machines' firewall settings(if needed disable it)
- Edit /etc/xinet.d/telnet and mark the disable attribute to no (disable=no)
- Reload the xinet.d service (/etc/init.d/xinet.d reload)

Here is an excellent resource for installing / understanding Oracle RAC. Tarry did a neat job here by showing us how to install Oracle RAC on a Linux/Windows node using vmware virtualization software.Thanks Tarry!So if you are new and want to setup a Oracle RAC test environment without much of hardware constraints (vmware simulates network cards/shared disks etc) then check this out!
