[Xen-users] Dedicating a physical CPU core to a domainU guest
Just like dedicating a PCI device to one of the dom-U guests, Is it possible to dedicate a physical CPU core to any of the dom-U guests?

RE: [Xen-users] Dedicating a physical CPU core to a domainU guest
You could use the cpus options in your configuration file. e.g. you have 4 processors you can make the domU use only processor 1 with: cpus = "0" # all vcpus run on CPU0 For all of your other domUs cpus = "^0" # all vcpus run on !CPU0 or cpus = "1-3" # all vcpus run on CPU1-CPU3 or cpus = "1,2,3" # all vcpus run on CPU1,CPU2,CPU3 check the example configuration files for more information. The difference with this to assigning PCI devices to a domU is that the dom0 kernel will still use this processor.
