64 bit opensolaris guest

[srimalik]

Hi, all

I am running VirtualBox v=2.1.2 on an RHEL5(amd64) host, I already have RHEL5_x64 and unbuntu_x64 guests running on it but when I tried installing opensolaris11 it installed in 32 bit mode, while I expected it to be installed in 64 bit mode.
I used an iso kept on my filesystem instead of a CD, but I think that should not matter.

Has anybody else faced similar issues ?

Thanks
Sri
