By default, the virtual machine is configured to have 1 CPU and 1024MiB memory. It may be too small for testing with desktop environment enabled inside. You can set options <code>virtualisation.cores</code> and <code>virtualisation.memorySize</code> to enlarge the CPU cores and memory size for the virtual machine. Note that due to [https://github.com/NixOS/nixpkgs/issues/59219 issue 59219], you need to import an extra module in order to use these options. | |||
