[Libguestfs] [PATCH v2 1/4] appliance: Use dhclient instead of hard-coding IP address of appliance.

qemu in SLIRP mode offers DHCP services to the appliance. We don't use them, but use a fixed IP address intead. This changes the appliance to get its IP address using DHCP. Note: This is only used when the network is enabled. dhclient is somewhat slower, but the penalty (a few seconds) is only paid for network users. We could consider using the faster systemd dhcp client instead. --- appliance/init | 9 +++------ appliance/packagelist.in | 1 + 2 files changed, 4 insertions(+), 6 deletions(-) diff --git a/appliance/init b/appliance/init index 6d62338..d688a52 100755 --- a/appliance/init +++ b/appliance/init @@ -79,12 +79,9 @@ hwclock -u -s ip addr add 127.0.0.1/8 brd + dev lo scope host ip link set dev lo up -ip addr add 169.254.2.10/16 brd + dev eth0 scope global -ip link set dev eth0 up - -ip route add default via 169.254.2.2 - -echo nameserver 169.254.2.3 > /etc/resolv.conf +if grep -sq guestfs_network=1 /proc/cmdline; then + dhclient +fi # Scan for MDs. mdadm -As --auto=yes --run diff --git a/appliance/packagelist.in b/appliance/packagelist.in index 276b4c2..4e93eaf 100644 --- a/appliance/packagelist.in +++ b/appliance/packagelist.in @@ -210,6 +210,7 @@ binutils bzip2 coreutils cpio +dhclient diffutils dosfstools e2fsprogs -- 2.0.4
