2015-03-25powerpc: fix -machine usb=no for newworld and pseries machinesPaolo Bonzini
Capture the explicit setting of "usb=no" into a separate bool, and use it to skip the update of machine->usb in the board init function. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2015-03-16migration: Allow to suppress vmdesc submissionAlexander Graf
We now always send a JSON blob describing the migration file format as part of the migration stream. However, some tools built around QEMU have proven to stumble over this. This patch gives the user the chance to disable said self-describing part of the migration stream. To disable vmdesc submission, just add -machine suppress-vmdesc=on to your QEMU command line.

2014-11-04sysbus: Make devices spawnable via -deviceAlexander Graf
Now that we can properly map sysbus devices that haven't been connected to something forcefully by C code, we can allow the -device command line option to spawn them. For machines that don't implement dynamic sysbus assignment in their board files we add a new bool "has_dynamic_sysbus" to the machine class. When that property is false (default), we bail out when we see dynamically spawned sysbus devices, like we did before. Signed-off-by: Alexander Graf <agraf@suse.de>

2014-08-28intel-iommu: add Intel IOMMU emulation to q35 and add a machine option ↵Le Tan
"iommu" as a switch Add Intel IOMMU emulation to q35 chipset and expose it to the guest. 1. Add a machine option. Users can use "-machine iommu=on|off" in the command line to enable/disable Intel IOMMU. The default is off. 2. Accroding to the machine option, q35 will initialize the Intel IOMMU and use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for the pci bus. 3. q35_host_dma_iommu() will return different address space according to the bus_num and devfn of the device.
