VMware has the notion of a "cell" where VMs can be scheduled only within a cell, not across cells. Cell boundaries are determined by VMware by default, though certains settings can override them. An interesting project might be to implement "numa=cell" for Xen.... or maybe something similar is already in George Dunlap's scheduler plans? > -----Original Message----- > From: Keir Fraser [mailto:keir.fraser@xxxxxxxxxxxxx] > Sent: Wednesday, November 04, 2009 5:33 AM > To: Papagiannis Anastasios; xen-devel@xxxxxxxxxxxxxxxxxxx > Subject: Re: [Xen-devel] Xen 3.4.1 NUMA support > > > Add Xen boot parameter 'numa=on' to enable NUMA detection. > Then it's up to > you to, for example, pin domains to specific nodes, using the > 'cpus=...' > option in the domain config file.
