Configuring GRUB

You can use these GRUB parameters to configure the Virtualization hypervisor:

mem

This limits the amount of memory that is available for domain0.

com1=115200, 8n1

This enables the first serial port in the system to act as serial console (com2 is assigned for the next port, and so on...).

dom0_mem

This limits the amount of memory that is available for domain0.

dom0_max_vcpus

This limits the amount of CPUs visible to domain0.

acpi

This switches the ACPI hypervisor to the hypervisor and domain0. The ACPI parameter options include:

/*   ****  Linux config options: propagated to domain0  ****/

/*   "acpi=off":      Disables both ACPI table parsing and interpreter.   */

/*   "acpi=force":    Overrides the disable blacklist.                    */

/*   "acpi=strict":   Disables out-of-spec workarounds.                   */

/*   "acpi=ht":       Limits ACPI from boot-time to enable HT.            */

/*   "acpi=noirq":    Disables ACPI interrupt routing.                    */

noacpi

This disables ACPI for interrupt delivery.
