+# Configure guest CPUID responses:

+#cpuid=[ '1:ecx=xxxxxxxxxxx00xxxxxxxxxxxxxxxxxxx,
+# eax=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' ]
+# - 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=xxxxxxxx00000001xxxxxxxxxxxxxxxx,
+# edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
+# '0x80000008:ecx=xxxxxxxxxxxxxxxx0000xxxx00001010']
+# - CPUID.1[EBX] : (Thread * Cores ) per processors
+# - CPUID.1[EDX][HT] : Enable HT
+# - CPUID.0x80000008[ECX] : Number of vcpus * 2
+#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=xxxxxxxxxx0000xx00xxx0000000xx0,
+# edx=xx00000xxxxxxx0xxxxxxxxx0xxxxxx',

+# '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 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' ]

+# Configure guest CPUID responses:
+#
+#cpuid=[ '1:ecx=xxxxxxxxxxx00xxxxxxxxxxxxxxxxxxx,
+# eax=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' ]
+# - 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=xxxxxxxx00000001xxxxxxxxxxxxxxxx,
+# edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
+# '0x80000008:ecx=xxxxxxxxxxxxxxxx0000xxxx00001010']
+# - CPUID.1[EBX] : (Thread * Cores ) per processors
+# - CPUID.1[EDX][HT] : Enable HT
+# - CPUID.0x80000008[ECX] : Number of vcpus * 2
+#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=xxxxxxxxxx0000xx00xxx0000000xx0,
+# edx=xx00000xxxxxxx0xxxxxxxxx0xxxxxx',

+# '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 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' ]
