In virtualization, it aparently makes sense to provide virtual 32 bit machines instead of 64, even if the host hardware is 64 bit. Apparently they use less resources. But this could use a way more modern variant that the P-IV.
32 bit is only useful in a VM if you are providing the guest 2GB of RAM or less. 64 bit on 2GB or less of RAM is less efficient due to the larger RAM addressing scheme wasting space.
32 bit will eventually go away, I do not know why anyone would want to keep using a P4 with 1GB of Ram when they could upgrade to a much better system at a very low cost like a Core II Duo for example.
Because we already have the hardware and it costs money to replace it!
Boundries are a bit different Upper limit is about 3GB internal mem. Above that, older systems had to go for PAE. otoh, I have lots of virtual machines with just 512MB or even less. servers without X, don't require much.
