Hi,
I decided to try QEMU to install a simple basic win10.
As I wanted to keep it minimal I try first with 32bits install.
I follow the wiki page
qemu-img create -f raw qemu_win1032.raw 20G
qemu-system-x86_64 -cdrom Win10_21H2_French_x32.iso -boot menu=on -drive file=qemu_win1032.raw,format=raw -m 4G
It works pretty well picking "Family/Home" version... until it reboots where I get an endless "Preparation...."
Before I saw "Starting service" and "Preparing devices".
Nothing special shows in the console.
It tried with 64 version
qemu-img create -f raw qemu_win1064.raw 20G
qemu-system-x86_64 -cdrom Win10_21H2_French_x64.iso -boot menu=on -drive file=qemu_win1064.raw,format=raw -m 4G
I go not even that far! I got a wonderful blue screen at first cdrom boot related to "System thread exception not handled"
Any idea what qemu parameter I am missing here?
Thx

Trying to insist a bit with win10 32 bits / professionnal .... disk a bit bigger 32G
after a long long time the 2nd reboot happened .... now it crashes systematically and ask to restart . Not sure if good new or not!
It refers to check my wifi/network looking for update ... maybe something to look after?

I have never run Windows with Qemu, so I don't exactly know what is correct or what isn't.
What I seem to miss here is '-enable-kvm' you also didn't mention if you installed drivers ... virtio?
While I find our wiki very good may I suggest you have a look at Gentoo wiki, they have a separate page for Windows guests on Qemu https://wiki.gentoo.org/wiki/QEMU/Windows_guest

I recommend 'virt-manager' as a GUI for QEMU or at least as a starting point. It has many templates for different OS. You can also extract the QEMU cmdline out of the logs if you need it. That's very handy.

Thx interesting info in gentoo article. It seems to suggest LVM is a must for win10 guest.
I did not want first to go that road as I was aiming to create the most platform agnostic image to use both on Intel and ARM host.
I was under the impression that LVM & qcow2 are more efficient… at the cost of portability.
QEMU&raw for portability as priority.
Maybe I got it wrong!
Will check what virt-manager propose. Thx I missed it.

Hi,
You need a better hardware for Win10, haha, just some parameters will fix...
better hardware than the default (pc)
-machine type=q35
but the secret is this...
-cpu host,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-time
I suggest also add
-device qemu-xhci -device usb-tablet
Offline
Thx!
So LVM/Vtio is the only way …

LVM? Than short for LinuxVolumeManagement which is for Linux not Windows.
Anyway, djgera probably gave some excellent pointers you could add to that script you find on Gentoo wiki.
This would translate into something like:
Like I said before haven't used Windows on Qemu, test it yourself!
#!/bin/sh
exec qemu-system-x86_64 -enable-kvm \
-machine type=q35 \
-cpu host,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-time \
-device qemu-xhci -device usb-tablet \
-drive file=WindowsVM.img,if=virtio \
-net nic -net user,hostname=windowsvm \
-m 1G \
-monitor stdio \
-name "Windows" \
"$@"
This may be a good read too; https://access.redhat.com/articles/2470791

Thx ... I mixed up ... meant KVM!
Need to find out how to mount 2 cdrom isos at the same time (os & driver/virtio isos) ... should be straight forward but we are in Newbie Corner ;-)
Or should it/can be done in 2 steps? install os then driver?

My version of the script
#!/bin/sh
exec qemu-system-x86_64 -enable-kvm \
-machine type=q35 \
-cpu host,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-time \

-boot menu=on \
-net nic -net user,hostname=windows1064 \
-m 4G \
-monitor stdio \
-name "Windows 10 64 bits" \
"$@"
Which I launch as
./qemu_win1064.sh -cdrom Win10_21H2_French_x64.iso
but hdd not recognize (missing driver)
Probably need to remove the virtio parameter for the intial install
Going for
#!/bin/sh
exec qemu-system-x86_64 -enable-kvm \
-machine type=q35 \
-cpu host,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-time \
-device qemu-xhci -device usb-tablet \
-drive file=qemu_win1064.img,format=qcow2 \
-boot menu=on \
-net nic -net user,hostname=windows1064 \
-m 4G \
-monitor stdio \
-name "Windows 10 64 bits" \
"$@"

Output of
# modprobe kvm_amd
(run as root) ?
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

What's the output of 'uname -a'?

In my case just needed to activate virtualization in the bios ... but
Victory!
Now the basic installation is done.
Thx again
Now wondering if I really need those "virtio" drivers ...
[EDIT]
I could have done it from the beginning (missed the line from Gentoo page)
./WindowsVM.sh -boot d -drive file=WINDOWS.iso,media=cdrom -drive file=DRIVER.iso,media=cdrom
So the correct file to install/boot is
#!/bin/sh
exec qemu-system-x86_64 -enable-kvm \
-machine type=q35 \
-cpu host,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-time \
-device qemu-xhci -device usb-tablet \
-drive file=qemu_win1064.img,format=qcow2,if=virtio \
-boot menu=on \
-net nic -net user,hostname=windows1064 \
-m 4G \
-monitor stdio \
-name "Windows 10 64 bits" \
-drive file=Win10_21H2_French_x64.iso,media=cdrom \
-drive file=virtio-win-0.1.215.iso,media=cdrom \
"$@"
