Re: [Xen-users] use all of my cpu cores

[Tarun Dua <tarundua@xxxxxxxxx>]

I have the same problem on CentOS 6.3 :-

/proc/cpuinfo shows only 16 VCPUs.

It should have 24 VCPUs based on the HW config:- Hyperthreaded 2 x Intel Xeon E5-2620

uname -a says :-

3.7.9-1.el6xen.x86_64 

xen-hypervisor-4.2.1-4.el6.x86_64
xen-runtime-4.2.1-4.el6.x86_64
kernel-xen-release-6-4.noarch
xen-libs-4.2.1-4.el6.x86_64
kernel-xen-firmware-3.7.9-1.el6xen.x86_64
xen-4.2.1-4.el6.x86_64
xen-licenses-4.2.1-4.el6.x86_64
kernel-xen-3.7.9-1.el6xen.x86

grub.conf looks like this :-
