I am implementing Oracle RAC using 11.2. For shared disc option and low cost, we are planning to use Virtual Machines. I have installed one virtual machine (PARENT) Specifications: Oracle Linux 5.8 (64 bit) RAM 16GB HDD 90GB CPU 1

After installing VM, I tried to install another VM (CHILD) using Oracle Virtual Box. Specification for CHILD vm Oracle Linux 5.8 (32 bit) [ as Oracle VM doesnt give a 64 bit option while installing Child virtual machine] RAM 2GB HDD 50GB CPU 1

It's giving error

Starting udev:................................[Failed]


What is the possible the possible reason?

I want to use Oracle RAC using Linux 5.8. We have don't have other option than Linux. What is the procedure which I need to follow.

When I am installing Oracle VM Box on 64 bit machine. The option for 64 bit child machine is not available at the time of creating virtual machine


Nested virtual machines are not supported in VirtualBox. 64 bit options don't show up because they require hardware virtualization, which is not available in virtual machines.
