Mode, so the recommended is 320x240, 640x480, 800圆40.Ī timeout could be passed to bios, guest will pause for The resolution should be supported by the SVGA limitation: The splash file could be a jpeg file or a BMP file in 24īPP format(true color). Show it as logo, when option splash= sp_name is given and menu=on, The default isĪ splash picture could be passed to bios, enabling user to Menu=on as far as firmware/BIOS supports them. Interactive boot menus/prompts can be enabled via Order only on the first startup, specify it via once. The x86 PC uses: a, b (floppy 1Īnd 2), c (first hard disk), d (first CD-ROM), n-p (Etherboot from networkĪdapter 1-4), hard disk boot is the default. Letters depend on the target achitecture. Specify boot order drives as a string of drive letters. To createĪ device which is not created automatically and set properties on it, In particular, you can use this to set driver properties forĭevices which are created automatically by the machine model. Qemu-system-i386 -global ide-drive.physical_block_size=4096 -drive file=file,if=ide,index=0,media=disk prop = value Set default value of driver's property prop to value, arg = value Set parameter arg for item id of type group drive file=/dev/fdset/2,index=0,media=disk add-fd fd=4,set=2,opaque="rdonly:/path/to/file" You can open an image using pre-opened file descriptors from an fd VCPUs respectively, and possibly -object to specify the memoryįurthermore, if one node uses memdev, all of them have to useįd= fd ,set= set Add a file descriptor to an fd set. Still has to use the -m, -smp options to allocate RAM and Is, it just assigns existing resources to NUMA nodes. numa option doesn't allocate any of the specified resources. If mem, memdev andĬpus are omitted, resources are split equally. Node ] Simulate a multi node NUMA system. Maxcpus specifies the maximum number of hotpluggable CPUs. Values is given, the total number of CPUs n can be omitted. Number of threads per cores and the total number of socketsĬan be specified. For the PC target, the number of cores per socket, the On Sparc32 target, Linux limits the number of usableĬPUs to 4. On the PC target, up to 255ĬPUs are supported. cpu model Select CPU model ( "-cpu help" for list name ] Select the emulated machine by name.
