    build: Do not compress the (already compressed) VM qcow2 images.
    
    The qcow2 format supports compression, and the qcow2 type supported by 'guix
    system image' produces compressed qcow2 images.
    
    * Makefile.am (release): Do not re-compress the qcow2 VM images with xz.
    * doc/guix.texi (Running Guix in a VM): Adjust VM image URL.

 @cindex virtual machine
 To run Guix in a virtual machine (VM), one can use the pre-built Guix VM image
 distributed at
-@url{@value{BASE-URL}/guix-system-vm-image-@value{VERSION}.x86_64-linux.qcow2.xz}.
+@url{@value{BASE-URL}/guix-system-vm-image-@value{VERSION}.x86_64-linux.qcow2}.
 This image is a compressed image in QCOW format.  You will first need to
 decompress with @command{xz -d}, and then you can pass it to an emulator such
 as QEMU (see below for details).
