Everytime I try to open VBox, this error will display:
A Domain Name Server (DNS) for NAT networking could not be determined. Please check your /etc/resolv.conf for nameserver entries. Either add one manually (man resolv.conf) or ensure that your host is correctly connected to an ISP. If you ignore this warning the guest will not be able to perform nameserver lookups and it will probably observe delays if trying so.
Error ID:
NoDNSforNAT
Severity:
Warning
What should I do?
