Struct GuestNetworkConfig 

pub struct GuestNetworkConfig {
    pub guest_ip: Ipv4Addr,
    pub gateway_ip: Ipv4Addr,
    pub prefix_len: u8,
    pub guest_ip6: Ipv6Addr,
    pub gateway_ip6: Ipv6Addr,
    pub prefix_len6: u8,
    pub guest_mac: [u8; 6],
    pub gateway_mac: [u8; 6],
    pub dns_server: Ipv4Addr,
    pub upstream_dns: Ipv4Addr,
}

Static guest network configuration for the virtio-net MVP.

This struct describes the two endpoints of the single virtual Ethernet link:

• the guest NIC (guest_*)
• the host-side gateway implemented by smolvm (gateway_*)

The link is dual-stack: a /30 IPv4 point-to-point pair and a /64 ULA IPv6 pair (fd53:4d00::/64 — 53:4d = “SM”, matching the MAC OUI scheme).

Fields

guest_ip: Ipv4Addr

Guest IPv4 address.

gateway_ip: Ipv4Addr

Gateway IPv4 address.

prefix_len: u8

Prefix length.

guest_ip6: Ipv6Addr

Guest IPv6 (ULA) address.

gateway_ip6: Ipv6Addr

Gateway IPv6 (ULA) address.

prefix_len6: u8

IPv6 prefix length.

guest_mac: [u8; 6]

Guest MAC address.

gateway_mac: [u8; 6]

Gateway MAC address.

dns_server: Ipv4Addr

DNS server address presented to the guest.

For virtio-net this is the gateway’s own address (gateway_ip): the guest sends DNS to the gateway, which forwards upstream to Self::upstream_dns.

upstream_dns: Ipv4Addr

Upstream resolver the gateway forwards guest DNS queries to.

Defaults to DEFAULT_DNS_ADDR; the launcher overrides it when the caller passes --dns <ip> so a VM on a network that blocks the default resolver can still resolve names.
