@anchor{guix system vm}
Build a virtual machine that contains the operating system declared in
@var{file}, and return a script to run that virtual machine (VM).
+To use this command, you may need to add the build users to the @code{kvm}
+group so they can access @file{/dev/kvm} (@pxref{Build Environment Setup}).
+
+On a GNU/Linux system, a build user pool groups may be changed like this
+(using Bash syntax and the @code{shadow} commands):
+
address@hidden
+# for i in `seq -w 1 10`;
+ do
+ usermod -G guixbuild,kvm guixbuilder$i;
+ done
address@hidden example

Arguments given to the script are passed to QEMU as in the example
below, which enables networking and requests address@hidden of RAM for the
emulated machine:
