Hi,
I have a Red Hat machine created in previous version of VirtualBox (can't remeber what version), that worked and is working without any problems even after upgrading VirtualBox to 3.2.10 (withou recreating the machine).

But, when I create a new machine using the same vdi in VirtualBox 3.2.10, Red Hat doesn't boot. It ends by giving "Kernel panic: No init found. Try passing init= option to kernel."

Can you help?
Thanks.

I would look closely at the settings. I just created a new VM using my RHEL-6 VDI ( I don't have 5.5 ) and had not problems.

VBox 3.1 (and older) had IDE disk controller by default
VBox 3.2 has SATA disk controller by default

If you upgrade, it won't change to new default, but if you recreate a new VM, it will.

Try to switch disk controller from SATA to IDE.
