I wanted to get more graphics memory on my QEMU Windows client.
I decided to install **Virtio** drivers for QEMU to achieve that purpose.
I create an *imagine_file* like this:
qemu-img create -f raw image_file 4G
Also, I ran the windows-install like this:
qemu-system-x86_64 -enable-kvm -m 4G -cdrom "OS.iso" -boot order=c -drive file=image_file,if=virtio
But when Windows ran, it didn't find any hard-drive (the *image_file*
basically). It asked for some drivers instead. I think it wanted drivers
to communicate with the hard-drive (*image_file*).
Running the install without Virtio works though:
qemu-system-x86_64 -enable-kvm -m 4G -cdrom "OS.iso" -boot order=d -drive file=image_file,format=raw
The difference betweeen the two commands is:
order=c vs order=d
and
if=virtio vs format=raw
How do I install windows with Virtio in QEMU?
My original goal is to get 512 MB of graphics memory on Windows (running
as a guest in QEMU). Unfortunately, by default (no Virtio) I get 8MB of
video memory which is not enough for my purposes
Thanks
P.S. My OS is Arch-Linux

Since you use ArchLinux, wiki.archlinux.org is rather helpful, as always. Yes,
you need virtio drivers:

Hello Fam.
I managed to installed Windows with the *Virtio* drivers. Thanks for your
tip.
It has made a change in that I got 2X more graphics memory. But not nearly
enough. I need 512 and now I have 16.
How do I specify to Virtio how much memory to allocate?
Thanks
Jenia
