Screen resolution on KVM guest, how to do it?

Question

Windows

There is a host machine, a small server, without a PCI video card.
On the KVM server virtualization, through libvirt.
Two virtual guest machines with windows 7 are deployed.
Connection to guests is made through Teamwiever 11. The
maximum resolution is 1024x768 (4:3). The
virtual video card is installed by cirus.
Q:
How do I achieve a 16:9 aspect ratio?

Answer 1

Set the video card type in the settings to SPICE / QXL and enable the tunnel for the agent, and install the drivers from QXL and the SPICE agent on the guest machine . Then you will not only be able to set any resolution, but the resolution will also change depending on the size of the window, as in VirtualBox
