qemu: Add support for SMBIOS command line otions (Alex Williamson)
Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.
Binary SMBIOS entries can be generated as follows:
dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin
These can then be passed to the BIOS using this switch:
-smbios file=smbios_type_1.bin
Command line generation supports the following syntax:
-smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
-smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
[,uuid=$(uuidgen)][,sku=str][,family=str]
For instance, to add a serial number to the type 1 table:
-smbios type=1,serial=0123456789
Interface is extensible to support more fields/tables as needed.

extend -smp parsing to include cores= and threads= options
For injecting multi-core and multi-threading CPU topology into guests
extend the -smp syntax to accommodate cores and threads specification.
Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\
[,socket=nr_sockets][,maxcpus=max_cpus]
smp_value is the legacy value specifying the total number of vCPUs for
the guest. If you specify one of cores, threads or sockets this value
can be omitted. Missing values will be computed to fulfill:
smp_value = nr_cores * nr_threads * nr_sockets
where it will favour sockets over cores over threads (to mimic the
current behavior, which will only inject multiple sockets.)
So -smp 4,threads=2 will inject two sockets with 2 threads each,
-smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1.
If max_cpus (the number of hotpluggable CPUs) is omitted, it will
be set to smp_value.

qdev-ify virtio-blk.
First user of the new drive property. With this patch applied host
and guest config can be specified separately, like this:
-drive if=none,id=disk1,file=/path/to/disk.img
-device virtio-blk-pci,drive=disk1
You can set any property for virtio-blk-pci now. You can set the pci
address via addr=. You can switch the device into 0.10 compat mode
using class=0x0180. As this is per device you can have one 0.10 and one
0.11 virtio block device in a single virtual machine.
Old syntax continues to work. Internally it does the same as the two
lines above though. One side effect this has is a different
initialization order, which might result in a different pci address
being assigned by default.
Long term plan here is to have this working for all block devices, i.e.
once all scsi is properly qdev-ified you will be able to do something
like this:
-drive if=none,id=sda,file=/path/to/disk.img
-device lsi,id=lsi,addr=<pciaddr>
-device scsi-disk,drive=sda,bus=lsi.0,lun=<n>

extend -smp parsing to include cores= and threads= options
For injecting multi-core and multi-threading CPU topology into guests
extend the -smp syntax to accommodate cores and threads specification.
Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\
[,socket=nr_sockets][,maxcpus=max_cpus]
smp_value is the legacy value specifying the total number of vCPUs for
the guest. If you specify one of cores, threads or sockets this value
can be omitted. Missing values will be computed to fulfill:
smp_value = nr_cores * nr_threads * nr_sockets
where it will favour sockets over cores over threads (to mimic the
current behavior, which will only inject multiple sockets.)
So -smp 4,threads=2 will inject two sockets with 2 threads each,
-smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1.
If max_cpus (the number of hotpluggable CPUs) is omitted, it will
be set to smp_value.

extend -smp parsing to include cores= and threads= options
For injecting multi-core and multi-threading CPU topology into guests
extend the -smp syntax to accommodate cores and threads specification.
Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\
[,socket=nr_sockets][,maxcpus=max_cpus]
smp_value is the legacy value specifying the total number of vCPUs for
the guest. If you specify one of cores, threads or sockets this value
can be omitted. Missing values will be computed to fulfill:
smp_value = nr_cores * nr_threads * nr_sockets
where it will favour sockets over cores over threads (to mimic the
current behavior, which will only inject multiple sockets.)
So -smp 4,threads=2 will inject two sockets with 2 threads each,
-smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1.
If max_cpus (the number of hotpluggable CPUs) is omitted, it will
be set to smp_value.

extend -smp parsing to include cores= and threads= options
For injecting multi-core and multi-threading CPU topology into guests
extend the -smp syntax to accommodate cores and threads specification.
Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\
[,socket=nr_sockets][,maxcpus=max_cpus]
smp_value is the legacy value specifying the total number of vCPUs for
the guest. If you specify one of cores, threads or sockets this value
can be omitted. Missing values will be computed to fulfill:
smp_value = nr_cores * nr_threads * nr_sockets
where it will favour sockets over cores over threads (to mimic the
current behavior, which will only inject multiple sockets.)
So -smp 4,threads=2 will inject two sockets with 2 threads each,
-smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1.
If max_cpus (the number of hotpluggable CPUs) is omitted, it will
be set to smp_value.

qemu: Add support for SMBIOS command line otions (Alex Williamson)
Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.
Binary SMBIOS entries can be generated as follows:
dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin
These can then be passed to the BIOS using this switch:
-smbios file=smbios_type_1.bin
Command line generation supports the following syntax:
-smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
-smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
[,uuid=$(uuidgen)][,sku=str][,family=str]
For instance, to add a serial number to the type 1 table:
-smbios type=1,serial=0123456789
Interface is extensible to support more fields/tables as needed.

qemu: Add support for SMBIOS command line otions (Alex Williamson)
Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.
Binary SMBIOS entries can be generated as follows:
dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin
These can then be passed to the BIOS using this switch:
-smbios file=smbios_type_1.bin
Command line generation supports the following syntax:
-smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
-smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
[,uuid=$(uuidgen)][,sku=str][,family=str]
For instance, to add a serial number to the type 1 table:
-smbios type=1,serial=0123456789
Interface is extensible to support more fields/tables as needed.

extend -smp parsing to include cores= and threads= options
For injecting multi-core and multi-threading CPU topology into guests
extend the -smp syntax to accommodate cores and threads specification.
Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\
[,socket=nr_sockets][,maxcpus=max_cpus]
smp_value is the legacy value specifying the total number of vCPUs for
the guest. If you specify one of cores, threads or sockets this value
can be omitted. Missing values will be computed to fulfill:
smp_value = nr_cores * nr_threads * nr_sockets
where it will favour sockets over cores over threads (to mimic the
current behavior, which will only inject multiple sockets.)
So -smp 4,threads=2 will inject two sockets with 2 threads each,
-smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1.
If max_cpus (the number of hotpluggable CPUs) is omitted, it will
be set to smp_value.
