为什么 resolvconf 不能生成 dns-server 或者如何排除故障？
root@openstack-controller-01[Standby]:/home/user01# cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

我配置了 /etc/network/interfaces 如下。
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
bond-master bond0
auto br-ex
allow-ovs br-ex
iface br-ex inet static
address 172.25.53.61
netmask 255.255.0.0
gateway 172.25.0.1
dns-nameservers 8.8.8.8
ovs_type OVSBridge
ovs_ports br-ex
ethtool -K bond0 gro off
pre-up ifup bond0
post-up ovs-vsctl add-port br-ex bond0
post-down ifdown bond0
auto bond0
iface bond0 inet manual
up ip address add 0/0 dev $IFACE
up ip link set $IFACE up promisc on
down ip link set $IFACE down promisc off
down ifconfig $IFACE down
slaves none
xmit-hash-policy layer2+3
ovs_bridge br-ex
ovs_type OVSPort
pre-up ifup eth0
post-down ifdown eth0
auto eth1
iface eth1 inet manual
bond-master bond1
auto bond1
iface bond1 inet static
address 192.168.1.61
netmask 255.255.255.0
xmit-hash-policy layer2+3
slaves none
pre-up ifup eth1
post-down ifdown eth1
然后，我确认了其他节点。
它仅设置了绑定配置。
auto bond0
iface bond0 inet static
address 192.168.0.5
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.254
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 8.8.8.8
dns-search local.mki
slaves eth0
xmit-hash-policy layer2+3
auto eth0
iface eth0 inet manual
bond-master bond0
auto bond1
iface bond1 inet static
address 192.168.1.5
netmask 255.255.255.0
slaves eth1
xmit-hash-policy layer2+3
auto eth1
iface eth1 inet manual
bond-master bond1
此节点具有正确的名称服务器设置。
root@openstack-compute-01:/home/user01# cat /etc/resolv.conf

# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8

我认为这与 openvswitch 有关，但我不确定。
如果您有任何知识，请告诉我。
非常感谢。
