You are running a Debian in a KVM VM. You installed spice-vdagent, started and enabled the service, yet nothing works. No screen resizing, nothing. Note: This problem still exists in Debian 12.2 Here’s the fix: Copy spice-vdagent.desktop to User’s Autostart Directory: Edit the Copied File Open ~/.config/autostart/spice-vdagent.desktop with a text editor.
You can set static IP addresses (DHCP reservations) for your virtual machines in KVM/QEMU using libvirt’s built-in DNS/DHCP server. This is done by modifying the network definition XML file.
