I'm sorry for replying this mail for so long. I named the 'Cross-Platform KVM' fvm ( 'f' is the beginning of my name :) ). The kernel module is based on kvm-kmod 3.4, and the qemu (version 1.1~1.6) can be patched easily for fvm. I named the kernel module vmmr0 (VMM in Ring0). Not like the 'WinKVM' by Kazushi Takahashi, fvm is easy to compile and use. The build environment for windows is mingw-w64. I will sum up the internals of fvm, and release the docs and codes on github later. The code of vmmr0 is disordered, so I will reorganize it before releasing. Before this, I commited a binary package for windows on github: https://github.com/fanwenyi0529/fvm-release to use the fvm for windows, we should follow these steps: you should have a computer which installed 64-bit windows 7 or higher. 1. enable 'Lock pages in memory' of current user in gpedit.msc: http://msdn.microsoft.com/en-us/library/ms190730.aspx fvm use awe memory in order to lock guest 's page. Windows kernel do not have anything like mmu_notifier :( 2.windows x64 needs driver signing, so enable testmode. bcdedit -set testsigning on 3.reboot your computer. 4.install the vmmr0.sys kernel module as service named 'vmmr0' and start it. execute in cmd: sc create vmmr0 binpath="(path to vmmr0.sys)" type=kernel start=demand net start vmmr0 5. all done! Let 's run kvm on windows. eg: create a bat file , and type this in the target blank: (path to fvm-x86_64w.exe) -drive file=D:\vm\linux-0.2.img,cache=writeback -machine accel=kvm,kernel_irqchip=off -cpu qemu64,-vmx -smp sockets=1,cores=1 -m 128 -soundhw hda -net nic,model=e1000 -net user -rtc base=localtime -vga vmware Save and run this bat as admin. Known problems: 1. I have not implement the kernel_irqchip, so please disable the kirqchip support in cmdline like this: -machine accel=kvm,kernel_irqchip=off 2. the performance of windows x64 guests is poooor, I have not found the reason. 3. do not use vmware vga card if the guest is Ubuntu 12.04, or the qemu (version 1.3 )would core, qemu-1.6 is okay. 4. The mouse auto switching while running linux guests (Ubuntu, etc.) can not work. And the qemu will lost response. Please use vnc to run Ubuntu. 5. If your cpu do not support ept, please give the guest only 1vcpu if the guest is 64 bit. Or the guest will corrupt.

Is it based on a current kvm.git or some older Win32 KVM fork on SourceForge? If so, how invasive are your changes? Or is it a clean-room implementation of your own against the header/ioctl interface? How does it work technically? etc. Regards, Andreas -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
