Doing so gives me the flexibility to keep the old VM on the old laptop, and start with a fresh build of Windows. For me in particular, there is some software I need for work that can only run on Windows. Additionally, it may be useful to have Windows running directly on your hardware for things like gaming. It is convenient to be able to boot Windows as a virtual machine from Linux, and also reboot and boot from Windows directly if necessary.
After configuring a recovery disk and re-installing Windows , I booted into a Kubuntu After installing KVM , [2] I followed this tutorial to get it up and running. After a bit of troubleshooting, I found the right configuration archived link to get Windows up and running from Linux. Unfortunately, running from a live disk is different from my actual set up.
In the actual set up, I share the same EFI boot partition across two separate operating systems. Even if I could mount the boot partition as read-only, I run into the issue where my default configuration - booting Linux - would cause the VM to try to boot into Linux as well.
This is a bad. I spent some time trying to create my own efi partition as a virtual file and having it point to the Windows partition, but this does not work because EFI needs to be on the same physical disk as the OS partition.
This tutorial lays out the steps correctly archived link. I also assume you already have kvm installed on a modern Linux kernel. I am running on Kubuntu How would I make it work? I assume windows is missing drivers required for the qemu-emulated hardware to work. Improve this question. McEnroe McEnroe 1 1 gold badge 3 3 silver badges 5 5 bronze badges. Architecture is good, but I don't think there's anything one can do about the ahci since qemu doesn't seem to support it Try this: avforums.
And you always can turn off AHCI on physical machine and change it back, or even simply backup registry files. Show 2 more comments. Active Oldest Votes. Booting an native, physical Windows 7 partition can be done by this: Prepare requisites Windows 7 installation media, Virtio drivers.
Make your hard drive accessible read-only for your current user. Boot it using QEMU in snapshot mode. By the way, this works fine for Windows 10 as well. Download Virtio drivers, e. Improve this answer. The 10 reputation thing is a pain. It stopped me, and a lot of others, from giving the detailed kind of help we wanted. To be honest, 10 points are not too hard to get. The issue is that I am not able to find the screenshots anymore. I am pretty sure that they are somewhere on my disks, but Don't forget to remove -snapshot if you actually want to persist the stuff.
A quick update: I also managed to get the drivers installed with drvload. It MUST be renamed. This worked for me on arch linux — jameh. Add a comment. It says to listen on port localhost-only , adds SPICE channel between host and guest to allow remote copy-paste and 4 remotelly-attachable USB devices.
If the original local VM graphical output is not needed, add -display none parameter. Have fun with virtualized Windows and remember — Windows is good for games only and for stuff like government PDFs which use proprietary Adobe XFA forms and are therefore supported in official Adobe Reader which has the best support in this platform only. By default it is very limited maximum number or RAM, maximum number of CPU cores, maximum number of listening socket connections, etc until you pay huge amounts of money to Microsoft.
In my case qemu-windows. This second flash represented also as a file here stores the bios settings — mainly boot order the EFI boot order manages the OS like Windows or utility efibootmgr on Linux and BIOS stores it in this config flash. Thank you for these instructions. My Linux install is on the same disk as my Windows install.
Is there a way to boot Windows virtually when Linux and Windows are on the same physical device? Partitions are on different parts of the physical drive. And this is exactly what I am doing here. That Windows bootloader would then load that partition and continue normal windows booting. So you will use EFI partition initially, run Windows bootloader on it you can use EFI console mounted as cdrom at the beginning or use boot options of the TianoCore EFI firmware — hit ESC during boot , which then finds and loads the the big windows partition, mounts it and boots from it.
Thank you very much for these instructions. I was able to boot up my windows partition. I am not clear how to go about doing this and more specifically what drivers to install from the fedora repository. Could you please give some additional details on virtio driver installation in the windows guest? Fedora ships these drivers signed so they will install without any hacks.
Thanks for this. Saved me a ton of time. Used it to boot a copy of the WinEdge MS developer ova after converting it to qemu. Alternatively you can compile those drivers from the source code and disable driver signature verification in the Windows guest.
