Hi All,
If I understand the process correctly, when specifying the number
of guest cores in KVM, I am not actually specifying any particular physical
core: I am specifying how many connections to the cores I can have open
at once. I get the next free core, who ever that might be, up to the limit.
I have an i7 processor (love it!) with four physical cores. But Linux
thinks
I have 8 cores due to hyperthreading.
Here is where some confusion arises: Should I stick to four or fewer cores
in my KVM guest, or should I go for all eight?
I was thinking of six cores to leave some left over for the host. And an
even number as some of Microsoft's fine software freaks at an odd number
of cores (M$SQL server).
Many thanks,
-T
p.s. l since no one is going to believe me about M$SQL and odd cores,
this is straight from the horses mouth:

There are other instances, but I can not prove them. Things just
cleared up with an even number of cores (X5650 with 6/12 cores)
