Internet Connection Drop

[rootcj]

I am having a issue, that whenever i run Bootvm.sh file macos boots fine but the internet just droops, first i dual booted my windows witn xubuntu and faced this problem and thought that the problem might be because of xubuntu then i installed ubuntu as secondary os installed mac on it but facing the same issue here as well.
The problem continues whether i use wifi or ethernet my host as well as vm both gets disconnected from internet. as soon as i close the vm internet starts working on host.
