RE: [Xen-users] Dedicating a physical CPU core to a domainU guest

["James Dingwall" <james.dingwall@xxxxxxxxxx>]

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.

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?
