example: Use public DNS servers in VM network config#183
Merged
Conversation
On managed Macs, corporate network extensions block DNS traffic from the vmnet bridge to the host's resolver (mDNSResponder), causing DNS lookups in the VM to fail. This also prevents installing avahi-daemon, breaking mDNS-based IP discovery. Use 8.8.8.8 and 1.1.1.1 as static nameservers and disable DHCP-provided DNS, since the macOS host DNS cannot be trusted.

Allow overriding the default DNS servers (8.8.8.8, 1.1.1.1) for users
who prefer private DNS servers or have specific company policies.
Example:
% ./example test --dns-servers 10.0.0.1,10.0.0.2

The dns servers can be changed using new --dns-server= option.
