Sheng Yang commented on CLOUDSTACK-1094:
----------------------------------------

It's purely guest OS bug.

For CentOS 6.2, I've figured out:

1. Set dhcpname=localhost.localdomain
2. Modify the /etc/sysconfig/network-scripts/ifup-post, search for set_hostname, change the ip command above from:

ip -o -4 addr ls dev xxxx

to:

ip -o -6 addr ls dev xxxx

Would get centos the correct host name after reboot.

Obviously it's CentOS bug to only fetch the host name based on ipv4 address. I don't think we can do anything about it.
