I just checked installation of qemu-kvm & libvirt & virt-install on a Fedora
Server Edition, that is a headless server. It installed 338 packages / 158 mb including
poppler, mesa, wayland, libX11, gtk3, cairo and a lot of additional graphic related
software.
I’m wondering, why I need Wayland or X11 etc for kernel virtualization and running
virtual machines? It turns my headless server into a graphical workstation. It installs
software that I don't need for running a headless server, and don't want there.
qemu-kvm installs the full graphical virtualization stack. You want
qemu-kvm-core to get a subset without the graphical UI.
Those libraries are required for the QEMU GUI to work, which people
*do* use. It also allows QEMU to work properly as an X11/Wayland
client app in a desktop environment.
If I install the same combo on a Debian / Ubuntu headless Server it
installs about 40 packages / 20 mb. I know, the packages are not the same, but
Debian/Ubunt doesn’t need X11, poppler, mesa, etc. for virtualization on a headless
server. Can't we do the same?
By default, Debian does the same thing. The qemu-system-x86 package
recommends the qemu-system-gui package, which pulls in that stuff.
This is not "dependency hell". "Dependency hell" is a *very* specific
thing, and this isn't it.
