I have a CentOS 6 server with eight physical network adapters.
I want to run Windows Server 2008 R2 as a Guest OS in VirtualBox with a bridged network adapter. On my CentOS box eth2 (192.168.10.4) is the main network adapter. eth0 is the adapter I want to use for the bridged adapter for my first Guest OS.
In CentOS eth0 has an IP address of 192.168.10.17; my Guest OS has an IP of 192.168.10.10. There are no networking problems with this setup, everything works just fine. My problem is that I am using two IPs for a single Guest OS: 192.168.10.10 and 192.168.10.17.
Can I eliminate 192.168.10.17 on eth0 (by commenting out IPADDR in ifcfg-eth0), or are both IPs (on the host and guest) required?
