It appeared that the following naming convention in the domain config file: vcpus=2 cpus=[0,1] does not pin the first VCPU to the first physical CPU, and the second VCPU to the second physical CPU. How to get 1-1 mapping, which will survive the booting. Thanks, Vitaly. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

As we''re aiming at feature parity among xl and xm for Xen 4.2 release, I''ll start looking into it as soon as I can. I''ll let you (and the list) know when I''ll have something ready, ok?
