networking - Can't set manual IP to Virtualbox Host Only adapter in CentOS 6.5

When I configure the IP address of VirtualBox 4.3.2 (running on Windows 8.1) host only adapter, it changes it back to some other IP. Guest OS is CentOS 6.5.

I tried to set the IP in network connections in device manager. But I get this error after I clicked on properties of TCP/IPv4:

In order to configure tcp/ip you must install newtwork adapter.

I want to give these settings to Host only adapter:

• IP: 10.20.0.2


• Mask: 255.255.255.0

DHCP disabled.

But it automatically gets changed to something like:

• IP: 169.254.134.67 // Not fixed every time a new one


• Mask: 255.255.0.0

Here is the output of hostonlyifs:

C:\Program Files\Oracle\VirtualBox>VBoxManage list hostonlyifs

VBoxNetworkName: HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter

As you can see above it shows DHCP enbled even though I did not enable it.

I tried doing this:

VBoxManage hostonlyif ipconfig "VirtualBox Host-Only Ethernet Adapter" --ip 10.20.0.2 --netmask 255.255.255.0

Still nothing happens.

I have disabled APIPA now the IP gets changed to 0.0.0.0.
