"Unable to allocate and lock memory virtualbox"

[Phoxlox]

I'm trying to emulate Windows XP through Virtual Box with the latest version of it. But when I start the system, it appears Welcome to Windows XP and ends up crashing, appearing the error in the title. How can I fix it?

The specs from the Windows XP emulated :

System operational : Windows XP 32 bits
Principal memory : 2048 MB
Processors : 2

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

You are assigning memory to your guest, that you do not have available. Either close some applications on the host, buy more RAM for the host, or reduce the amount of RAM assigned to the guest.

PS. Editing a message does not notify anyone about the editing. You should have posted a new message with the log info.
PPS. You missed the "compress the log" part...
