‘nmi=dom0’: Inform DOM0 of the NMI.

‘nmi=ignore’: Ignore the NMI.

mem=xxx Set the physical RAM address limit. Any RAM appearing beyond this

physical address in the memory map will be ignored. This parameter may be

speciﬁed with a B, K, M or G sufﬁx, representing bytes, kilobytes, megabytes

and gigabytes respectively. The default unit, if no sufﬁx is speciﬁed, is bytes.

dom0

mem=xxx Set the amount of memory to be allocated to domain0. In Xen 3.x

the parameter may be speciﬁed with a B, K, M or G sufﬁx, representing bytes,

kilobytes, megabytes and gigabytes respectively; if no sufﬁx is speciﬁed, the

parameter defaults to kilobytes. In previous versions of Xen, sufﬁxes were not

supported and the value is always interpreted as kilobytes.

tbuf size=xxx Set the size of the per-cpu trace buffers, in pages (default 1). Note that

the trace buffers are only enabled in debug builds. Most users can ignore this

feature completely.

sched=xxx Select the CPU scheduler Xen should use. The current possibilities are

‘bvt’ (default), ‘atropos’ and ‘rrobin’. For more information see Section 7.4.

apic verbosity=debug,verbose Print more detailed information about local APIC

and IOAPIC conﬁguration.

lapic Force use of local APIC even when left disabled by uniprocessor BIOS.

nolapic Ignore local APIC in a uniprocessor system, even if enabled by the BIOS.

apic=bigsmp,default,es7000,summit Specify NUMA platform. This can usually be

probed automatically.

In addition, the following options may be speciﬁed on the Xen command line. Since

domain 0 shares responsibility for booting the platform, Xen will automatically propa-

gate these options to its command line. These options are taken from Linux’s command-

line syntax with unchanged semantics.

acpi=off,force,strict,ht,noirq,. . . Modify how Xen (and domain 0) parses the BIOS

ACPI tables.

acpi skip timer override Instruct Xen (and domain 0) to ignore timer-interrupt over-

ride instructions speciﬁed by the BIOS ACPI tables.

noapic Instruct Xen (and domain 0) to ignore any IOAPICs that are present in the

system, and instead continue to use the legacy PIC.

8.3 XenLinux Boot Options

In addition to the standard Linux kernel boot options, we support:

1 2 ... 40 41 42 43 44 45 46 47 48 49 50 ... 55 56
