Hi,
The cirros cloud images[1] appear to run a bunch of useful commands, and log
them to the nova console.log --
/var/lib/nova/instances/instance-foo/console.log by default. It was very useful
for debugging. The file size is just about 16K , and there is no considerable
performance impact either.
IMHO, we could do the same for Fedora cloud images -- which currently do not
log any info to console.log -- by default. it'll be useful troubleshoot
networking and other boot related problems.
Enumerating the list of commands cirros runs for reference:
$ /etc/rc.d/init.d/sshd start
$ ifconfig -a
$ route -n
$ cat /etc/resolv.conf
# pinging nameservers
$ uname -a
$ dmesg | tail
$ tail -n 25 /var/log/messages
Thoughts ?
