Hi,
I have two boxes with 2 * Xeon 3.0 Ghz
I''ve enabled Hyperthreading in the BIOS.
- One box is with Xen 3.0.1
I''ve enabled SMP + SMT in my kernel Xen0 config, and SMP + SMT works
perfectly.
I can see 4 cpus in my VCPU list for Domain0, and I see also 4 CPUs in the
/proc/cpuinfo file.
- One box is with Xen 3.0.2
I''ve enabled SMP in my kernel Xen0 config, and SMT has disappeared !
Thus I can see only 1 running cpu in my VCPU list (4 vcpu lines indeed), and
I see also only 1 CPU in the /proc/cpuinfo file.
I don''t really understand why SMT has disappeared from the kernel
configs,
and I can re-enable it... in order to have the same CPU config between 3.0.1
and 3.0.2
I''ve just seen a message in the Xen-users mailing-list archives
(http://lists.xensource.com/archives/html/xen-users/2006-04/msg00089.html),
but I don''t rellay know if it''s related to my problem. Thank
you for your
help.
