Guys, I''ve been setting up Xen on a dual Opteron box as I mentioned in my previous emails. Now all pieces seem to come together so I actually started to pay more attention to balancing available resources between domains. I started at the CPU. My question is if I set ''(dom0-cpus 1)'' in xend-config.sxp then why can I see dom0 using both processors when runnging ''xm vcpu-list 0''? root@jeff:/etc# xm vcpu-list 0 Name ID VCPU CPU State Time(s) Affinity Domain-0 0 0 0 -b- 548.4 any cpu Domain-0 0 1 1 r-- 365.1 any cpu What I do until I find a solution to the above mentioned problem(?) is I pin each vcpu of dom0 to the first physical cpu: root@jeff:/etc# xm vcpu-pin 0 0 0 root@jeff:/etc# xm vcpu-pin 0 1 0 root@jeff:/etc# xm vcpu-list 0 Name ID VCPU CPU State Time(s) Affinity Domain-0 0 0 0 r-- 551.2 0 Domain-0 0 1 0 --- 367.7 0 Is pinning dom0''s vcpus the solution to what I''d like to achieve at all? Any ideas howto make this change permanent? Is there any way to make dom0 see only 1 vcpu? Any suggestions, ideas, hints are welcome. Thanks, Frank PS: Debian 3.1 + self compiled Xen-3.0.0 (x86_64) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
