# Configure the behaviour when a domain exits. There are three ‘reasons’
# for a domain to stop: poweroff, reboot, and crash. For each of these you
# may specify:
#
# “destroy”, meaning that the domain is cleaned up as normal;
# “restart”, meaning that a new domain is started in place of the old
# one;
# “preserve”, meaning that no clean-up is done until the domain is
# manually destroyed (using xm destroy, for example); or
# “rename-restart”, meaning that the old domain is not cleaned up, but is
# renamed and a new domain started in its place.
#
# In the event a domain stops due to a crash, you have the additional options:
#
# “coredump-destroy”, meaning dump the crashed domain’s core and then destroy;
# “coredump-restart’, meaning dump the crashed domain’s core and the restart.
#
# The default is
#
# on_poweroff = ‘destroy’
# on_reboot = ‘restart’
# on_crash = ‘restart’
#
# For backwards compatibility we also support the deprecated option restart
#
# restart = ‘onreboot’ means on_poweroff = ‘destroy’
# on_reboot = ‘restart’
# on_crash = ‘destroy’
#
# restart = ‘always’ means on_poweroff = ‘restart’

# Configure guest CPUID responses:
#
#cpuid=[ ‘1:ecx=xxxxxxxxxxx00xxxxxxxxxxxxxxxxxxx,
# eax=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx’ ]
# – Unset the SSE4 features (CPUID.1[ECX][20-19])
# – Default behaviour for all other bits in ECX And EAX registers.
#
# Each successive character represent a lesser-significant bit:
# ‘1’ -> force the corresponding bit to 1
# ‘0’ -> force to 0
# ‘x’ -> Get a safe value (pass through and mask with the default policy)
# ‘k’ -> pass through the host bit value
# ‘s’ -> as ‘k’ but preserve across save/restore and migration
#
# Expose to the guest multi-core cpu instead of multiple processors
# Example for intel, expose a 8-core processor :
#cpuid=[‘1:edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx,
# ebx=xxxxxxxx00010000xxxxxxxxxxxxxxxx’,
# ‘4,0:eax=001111xxxxxxxxxxxxxxxxxxxxxxxxxx’]
# – CPUID.1[EDX][HT] : Enable HT
# – CPUID.1[EBX] : Number of vcpus * 2
# – CPUID.4,0[EAX] : Number of vcpus * 2 – 1
#vcpus=8
#
# Example for amd, expose a 5-core processor :
# cpuid = [‘1:ebx=xxxxxxxx00001010xxxxxxxxxxxxxxxx,
# edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx’,
# ‘0x80000001:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx1x’,
# ‘0x80000008:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxx001001’]
# – CPUID.1[EBX] : Threads per Core * Cores per Socket (2 * #vcpus)
# – CPUID.1[EDX][HT] : Enable HT
# – CPUID.0x80000001[CmpLegacy] : Use legacy method
# – CPUID.0x80000008[ECX] : #vcpus * 2 – 1
#vcpus=5
#
# Downgrade the cpuid to make a better compatibility for migration :
# Look like a generic 686 :
# cpuid = [ ‘0:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0’,
# ‘1:eax=0x06b1,
# ecx=xxxxxxxxxxx0000xx00xxx0000000xx0,
# edx=xxx00000xxxxxxx0xxxxxxxxx0xxxxxx’,
# ‘4:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0’,
# ‘0x80000000:eax=0x3,ebx=0x0,ecx=0x0,edx=0x0’]
# with the highest leaf
# – CPUID.0[EAX] : Set the highest leaf
# – CPUID.1[EAX] : 686
# – CPUID.1[ECX] : Mask some features
# – CPUID.1[EDX] : Mask some features
# – CPUID.4 : Reply like the highest leaf, in our case CPUID.3
# – CPUID.0x80000000 : No extension we are on a Pentium III, reply like the
# highest leaf (CPUID.3).
#
# Configure host CPUID consistency checks, which must be satisfied for this
# VM to be allowed to run on this host’s processor type:
#cpuid_check=[ ‘1:ecx=xxxxxxxxxxxxxxxxxxxxxxxxxx1xxxxx’ ]
# – Host must have VMX feature flag set
#
# The format is similar to the above for ‘cpuid’:
# ‘1’ -> the bit must be ‘1’
# ‘0’ -> the bit must be ‘0’
# ‘x’ -> we don’t care (do not check)
# ‘s’ -> the bit must be the same as on the host that started this VM
#—————————————————————————–
# Configure passthrough PCI{,-X,e} devices:
#
# pci=[ ‘[SSSS:]BB:DD.F[,option1[,option2[…]]]’, … ]
#
# [SSSS]:BB:DD.F “bus segment:bus:device.function”(1) of the device to
# be assigned, bus segment is optional. All fields are
# in hexadecimal and no field should be longer than that
# as shown in the pattern. Successful assignment may need
# certain hardware support and additional configurations
# (e.g. VT-d, see docs/misc/vtd.txt for more details).
#
# (1) bus segment is sometimes also referred to as the PCI “domain”,
# not to be confused with Xen domain.
#
#
# optionN per-device options in “key=val” format. Current
# available options are:
# – msitranslate=0|1
# per-device overriden of pci_msitranslate, see below
# – power_mgmt=0|1
# per-device overriden of pci_power_mgmt, see below
#
#pci=[ ’07:00.0′, ’07:00.1′ ]
# MSI-INTx translation for MSI capable devices:
#
# If it’s set, Xen will enable MSI for the device that supports it even
# if the guest don’t use MSI. In the case, an IO-APIC type interrupt will
# be injected to the guest every time a corresponding MSI message is
# received.
# If the guest enables MSI or MSI-X, the translation is automatically
# turned off.
#
#pci_msitranslate=1
# PCI Power Management:
#
# If it’s set, the guest OS will be able to program D0-D3hot states of the
# PCI device for the purpose of low power consumption.
#
#pci_power_mgmt=0
#—————————————————————————–
# Configure PVSCSI devices:
#
#vscsi=[ ‘PDEV, VDEV’ ]
#
# PDEV gives physical SCSI device to be attached to specified guest
# domain by one of the following identifier format.
# – XX:XX:XX:XX (4-tuples with decimal notation which shows
# “host:channel:target:lun”)
# – /dev/sdxx or sdx
# – /dev/stxx or stx
# – /dev/sgxx or sgx
# – result of ‘scsi_id -gu -s’.
# ex. # scsi_id -gu -s /block/sdb
# 36000b5d0006a0000006a0257004c0000
#
# VDEV gives virtual SCSI device by 4-tuples (XX:XX:XX:XX) as
# which the specified guest domain recognize.
#
#vscsi = [ ‘/dev/sdx, 0:0:0:0’ ]
