The driver adds a character device\n(/dev/kvm) that exposes the virtualization capabilities to userspace. Using\nthis driver, a process can run a virtual machine (a \"guest\") in a fully\nvirtualized PC containing its own virtual hard disks, network adapters, and\ndisplay.\n\nUsing this driver, one can start multiple virtual machines on a host.\n\nEach virtual machine is a process on the host; a virtual cpu is a thread in\nthat process. kill(1), nice(1), top(1) work as expected. In effect, the\ndriver adds a third execution mode to the existing two: we now have kernel\nmode, user mode, and guest mode. Guest mode has its own address space mapping\nguest physical memory (which is accessible to user mode by mmap()ing\n/dev/kvm). Guest mode has no access to any I/O devices; any such access is\nintercepted and directed to user mode for emulation.\n\nThe driver supports i386 and x86_64 hosts and guests. All combinations are\nallowed except x86_64 guest on i386 host. For i386 guests and hosts, both pae\nand non-pae paging modes are supported.\n\nSMP hosts and UP guests are supported. At the moment only Intel\nhardware is supported, but AMD virtualization support is being worked on.\n\nPerformance currently is non-stellar due to the naive implementation of the\nmmu virtualization, which throws away most of the shadow page table entries\nevery context switch. We plan to address this in two ways:\n\n- cache shadow page tables across tlb flushes\n- wait until AMD and Intel release processors with nested page tables\n\nCurrently a virtual desktop is responsive but consumes a lot of CPU. Under\nWindows I tried playing pinball and watching a few flash movies; with a recent\nCPU one can hardly feel the virtualization. Linux/X is slower, probably due\nto X being in a separate process.\n\nIn addition to the driver, you need a slightly modified qemu to provide I/O\ndevice emulation and the BIOS.\n\nCaveats (akpm: might no longer be true):\n\n- The Windows install currently bluescreens due to a problem with the\n virtual APIC. We are working on a fix. A temporary workaround is to\n use an existing image or install through qemu\n- Windows 64-bit does not work. That\u0027s also true for qemu, so it\u0027s\n probably a problem with the device model.\n\n[bero@arklinux.org: build fix]\n[simon.kagstrom@bth.se: build fix, other fixes]\n[uril@qumranet.com: KVM: Expose interrupt bitmap]\n[akpm@osdl.org: i386 build fix]\n[mingo@elte.hu: i386 fixes]\n[rdreier@cisco.com: add log levels to all printks]\n[randy.dunlap@oracle.com: Fix sparse NULL and C99 struct init warnings]\n[anthony@codemonkey.ws: KVM: AMD SVM: 32-bit host support]\nSigned-off-by: Yaniv Kamay \u003cyaniv@qumranet.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nCc: Simon Kagstrom \u003csimon.kagstrom@bth.se\u003e\nCc: Bernhard Rosenkraenzer \u003cbero@arklinux.org\u003e\nSigned-off-by: Uri Lublin \u003curil@qumranet.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Anthony Liguori \u003canthony@codemonkey.ws\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ] }
