i have vector 32 and 64 installed. 32 vector i easily installed virtual boxby downloading and then running it inthe terminal. but in 64vector, it said in the terminal that i had to install the build and header files for the current kernel3.2.22 for virtual box 4.2.4. i do not know how to go about doing this. any help is appreciated. i want to compare the functionality of vector32 vs. vector64 inregards the performance of virtual box, as i constantly load new distros via virtual box-there are so many!
