Also notice that the physical CPUs proper of Container 101 might not remain the same during the Container operation they might change for load balancing reasons, the only thing that cannot be changed is their maximal number. It means that, from this point on, the processes of Container 101 will be simultaneously executed on no more than 2 physical CPUs while the other Containers on the server will continue consuming the CPU time of all 4 server processors, if needed. The output shows that Container 101 is currently bound to only two processors on the server instead of 4 available for the other Containers on this server. Model name : Intel(R) Xeon(TM) CPU 2.80GHz If the Container and virtual machine are running a Linux operating system, you can also use the cat /proc/cpuinfo command to view the available CPUs, for example: To make sure that the number of CPUs has been successfully changed, you can log in to Container 101 and the MyVM virtual machine and check the number of available CPUs. For detailed information on the CPU hotplug feature, see Enabling CPU Hotplug for Virtual Machines. Before configuring the number of CPUs for a running virtual machine, make sure that the CPU hotplug support is enabled for this virtual machine. In this case, the 'physical CPUs' notation designates the number of CPUs the Parallels Server Bare Metal kernel is aware of (you can view this CPU number using the /proc/cpuinfo command).Ä¢. The number of CPUs for a virtual machine or Container must not exceed the number of physical CPUs installed on the server. The Linux CLI can provide you with detailed CPU information, such as the number of CPU cores, CPU architecture and CPU usage. any virtual machine and Container on the server can make use of these 4 processors, you can set the processes in Container 101 and in the MyVM virtual machine to be run on 2 CPUs only by issuing the following commands:Ä¡. For example, if your server has 4 physical processors installed, i.e. However, you can modify the number of physical CPUs which will be simultaneously available to a virtual machine or Container using the -cpus option of the pctl set command. any process in any virtual machine and Container can be executed on any processor on the server. By default, a virtual machine and Container is allowed to consume the CPU time of all processors on the server, i.e. cat /proc/cpuinfo processor : 0 vendorid.If your server has more than one physical processor installed, you can control the number of CPUs which will be used to handle the processes running in virtual machines and Containers. File /proc/cpuinfo will display the CPU information such as processor,CPU cores,cache size etc.
