Hello,
Does anyone happen to know how the upcoming multi-core CPU will be handled
by the kernel? Does it see each core as a physical or logical CPU or ?
Vanderpool is a hardware support for OS virtualization (running multiple OS
"at the same time"), how does Linux kernel make use of this, particularly
which part of the kernel code?
I poke around the source (2.6.10) some but haven't figured both issues out
yet.
Many thanks!
Linda

There's Xen support for upcoming VT, which will allow running unmodified
guest.
thanks,

Can't answer this, but I guess each core will be seen as a physical
CPU as they are real CPU cores, not just logical CPUs as with
multithreading.

At least, Xen will make great use of Vanderpool (VT) for
virtualization purpouses.
