More info please:
Sometime ago I got to virtualize this bare-metal WinXP laptop under *Ubuntu and I was happy.
Later on, the performance proved to be unbearable (processor pegged at 100% load 100% of the time) and I was unhappy.
Life went on.
Bug went itching...
Geek sprung into action and:
I vdi(ed) the laptop's HD and fired up a run-of-mill VM and...
surprise, surprise...
VirtualBox running in this AMD-64 processor (not sure what, research still not in full swing) runs my Virtual XP juuuuust fiiiine...
Same VM running on the Intel "Core Duo" of the laptop, SUUUUCKS! 100%... :(
4GB RAM both machines, *Ubuntu 10.04.
Does this make any sense?
