Problem of Copying the Original VM to 2nd VM in Oracle 11gR2 RAC system

Question

Folks,
Hello. I have been installing Oracle Database 11gR2 RAC system using 2 nodes that are 2 Virtual Machines (rac1 and rac2) on the top of VMPLayer 3.
I follow the tutorial http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html to do.
The original Virtual Machine rac1 has run correctly. I configure rac1 network (eth0 and eth1) by opening VM rac1 and using command "[root@rac1\] #neat" as root user to invoke the network configuration.
For the second Virtual Machine rac2, I simply copy all files in "C:\VM\rac1" into "C:\VM\rac2". Then I have done the following:
1) In the directory "C:\VM\rac2", rename "rac1.vmx" to "rac2.vmx".
2) Change display name from "rac1" to "rac2" in the file "rac2.vmx".
The next thing to do for rac2 is to open the Virtual Machine rac2 and configure its network (eth0 and eth1) by using the command "[root@rac2\]#neat" as root user.
But by this step, I don't understand how to open the Virtual Machine rac2 so that can configure its network (eth0 and eth1).
Can any folk tell me how to open the VM rac2 to configure its network by this step ?
Thanks.

Folks,
Hello. Thanks a lot for replying.
The public IP for eth0 and private IP for eth1 in the file "/etc/hosts" are as follows:
rac1 eth0 192.168.138.35 eth1 192.168.137.35
rac2 eth0 192.168.138.36 eth1 192.168.137.36
In rac1, I have added 2 entries in /etc/hosts as following:
#VIP for eth0
192.168.138.130 rac1-vip.localdomain rac1-genetic-vip
192.168.138.131 rac2-vip.localdomain rac2-cellar-vip
Then I execute the command: [root@rac1 /]# ping rac2
Output:
PING rac2.localdomain (192.168.138.36) 56(84) bytes of data
From rac1.localdomain (192.168.138.35) icmp_seq=1
Destination Host Unreachable
In rac2, I try to add the above 2 entries in /etc/hosts. But cannot save it. The following error message comes up:
"E45: readonly option is set (add ! to override)".
My questions are:
First, do I need to add VIP in the file "/etc/hosts" for both rac1 and rac2 ?
Second, why rac1 still cannot reach rac2 after add VIP in /etc/hosts for rac1 ?
Third, why the file "/etc/hosts" in rac2 is read-only ? How to change it to be editable ?
Thanks.
