Hi,I have a Quad Core CPU Dell PowerEdge R710 which has 4 Virtual Hosts running on top of it. I want to allocate a CPU core to each of the hosts.How can I do that on Xen.I am using Debian Lenny. -- Tapas +91 8971248477 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Assuming the 4 VMs are vmA, vmB, vmC and vmD and that Core 0 is allocated to Dom0 syntax (as provided in xm man page as well) is xm vcpu-pin <Domain> <VCPU> <CPUs> xm vcpu-pin vmA 0 1 xm vcpu-pin vmB 0 2 xm vcpu-pin vmC 0 3 xm vcpu-pin vmD 0 4 Hope this helps.

For best performance, I fixed dom0 to a single core and allow the remaining 3 cores to handle the guests. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
