Hi All,
This is confusing me for a while:
I am having Intel E5620 which is having *4 cores* and *8 threads*.
I am running *3* VMs lets say *vmA vmB vmC* on it using *xen 4.1.2* on
ubuntu 12.04 dom0.
.
As from the best practices i decided to assign each vm''s cpu to
physical
core and also to give *vmB *higher Weight in Credit-scheduler since its
running Mysql server(*I/O intensive*).
from *cat /proc/cpuinfo* its showing *8 CPU. D*oes that mean that i can
assign each vm 2 cpu each(2*3=6) and assign two cpu to Dom0(2*1=2) and
thus utilizing 8cpus(6+2).
like this:
*VM*
*xm vcpu-pin vmA 0 0*
*xm vcpu-pin vmA 1 1*
*xm vcpu-pin vmB 0 2*
*xm vcpu-pin vmB 1 3*
*xm vcpu-pin vmC 0 4*
*xm vcpu-pin vmC 1 5*
*
*
*Dom0 *
*xm vcpu-pin Domain-0 0 6*
*xm vcpu-pin Domain-0 1 7*
After setting this do we still need to Increase Weight for *vmB *after
assigning dedicated CPU.
Regards,
Kevin.Parker
