Default CPU Allocation
Default CPU Allocation
Like the memory settings discussed, the settings Shares, Reservation, and Limit can be configured for CPU. Figure 9.10 shows the default values for CPU Resource settings.
Figure 9.10 A virtual machine's CPU can be configured with Shares, Reservation, and Limit values.
When a new virtual machine is created with a single vCPU, the total maximum CPU cycles for that virtual machine equals the clock speed of the host system's core. In other words, if you create a new virtual machine, it can see through the “hole in the system board” and it sees whatever the core is in terms of clock cycles per second — an ESX host with 3GHz CPUs in it will allow the virtual machine to see one 3GHz core.
