Public bug reported:
Hi,
In my systems (all of them where I have openstack), I found that cloud-
init does not perform well. Mainly because the bridges I have were
created with ovs.
Since they are not ready at boot time it seems that the system got
stalled for a few mins. And after boot not all services recover.
For example rbdmap is not called again after the net is up.
It may be the order where the things are done. Or maybe something worse.
The problem is that cloud-init stalls for 2 mins on boot. RBD doesn't
run because cloud-init starts in nonet mode. And the whole system
becomes broken.
It's curious that ceph-osd are re-run after net is up. So some scripts
are relaunched. In fact two times. So they start to work well. But some
others no.

Bridge br-int

root@red-compute:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down
auto eth1
iface eth1 inet manual
up ifconfig $IFACE 0.0.0.0 up
down ifconfig $IFACE down
auto br-int
iface br-int inet dhcp
And when I boot up, cloudinit does not find the interfaces so no network
is up.
I have to take an screenshot of the issue. The problem is that rbd
storage is not boot up because cloudinit does not find the interfaces to
connect to the intranet (because it's a bridge), and all the system
becomes a nightmare.
