Bug#963797: qemu user-mode networking (SLIRP) DNS doesn't work without resolv.conf
Package: qemu-system-x86 Version: 1:5.0-5 resolv.conf(5) states: > If [/etc/resolv.conf] does not exist, only the name server on the local > machine will be queried, and the search list contains the local domain name > determined from the hostname. qemu user-mode networking (a.k.a SLIRP, a.k.a -netdev user) doesn't seem to follow this convention. Indeed, if the host doesn't have /etc/resolv.conf (or if it's empty), qemu is unable to answer DNS queries from the guest VM. The workaround is to create a valid /etc/resolv.conf with a "nameserver 127.0.0.1" line.
