Hi , Thanks for the suggestion , but my ultimate aim is to run ubuntu 20 , because the packages I would like to run as benchmarks require ubuntu 20 , so I just made. a trail with full fledged ubuntu 18 distribution, the light ones I tried from this link https://www.gem5.org/documentation/general_docs/fullsystem/guest_binaries are not getting simulated on qemu , as they exit ,upon that it does not have ubuntu 20 distribution .can you please suggest me what can be done on this ?
