Easy instructions to get QEMU/KVM and virt-manager up and running on Arch

1. Make sure your cpu support kvm with below command:

    grep -E "(vmx|svm)" --color=always /proc/cpuinfo
   

2. Make sure BIOS have enable “Virtualization Technology”.

3. User access to /dev/kvm so add your account into kvm(78) group:

#' When plotting multiple data series that share a common x axis but different y axes,
#' we can just plot each graph separately. This suffers from the drawback that the shared axis will typically
#' not align across graphs due to different plot margins.
#' One easy solution is to reshape2::melt() the data and use ggplot2's facet_grid() mapping. However, there is
#' no way to label individual y axes.
#' facet_grid() and facet_wrap() were designed to plot small multiples, where both x- and y-axis ranges are
#' shared acros all plots in the facetting. While the facet_ calls allow us to use different scales with
#' the \code{scales = "free"} argument, they should not be used this way.
#' A more robust approach is to the grid package grid.draw(), rbind() and ggplotGrob() to create a grid of 
#' individual plots where the plot axes are properly aligned within the grid.
