Re: [Xen-users] Bad network performance between VMs in a doma in.

[tgh <tianguanhua@xxxxxxxxxx>]

hi
 I have a question about credit and vcpuset
 credit could automatically allocate the doms among the cpus,and if we 
set the cpu to a domain statically ,will it potentially ruin the whole 
balancing of credit scheduler?
 and could credit not  automatically balance the load in the network 
scenario?
I am confuesd about it
could you help me out

Thanks in advance

> And how is the cores distributed between Dom0 and the two DomU's, are all using "any", or are the cores dedicated to a particular domain? If not, you may want to reduce the number of cores for Dom0 to 1 or 2, and set a dedicated core for each DomU. Setting Dom0 can be done with "xm vcpu-set" or modifying /etc/xen/xend-config.sxp (dom0-cpus n) where n is the number of CPU's for Dom0. If this number is zero, Dom0 has all CPU's in the system, and that will not be the ideal solution.
