Aaron Brady created CLOUDSTACK-9357:
---------------------------------------
Summary: DHCP DNS option is incorrect for Redundant Router config
Key: CLOUDSTACK-9357
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9357
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: SystemVM
Affects Versions: 4.8.0
Reporter: Aaron Brady
Priority: Minor
With two redundant system routers, my guests are given DNS option 6 containing
the *system* IP (not the virtual IP) of whichever router is master as their
first DNS server entry.
This means that if one router is down or stopped, DNS requests are slowed until
it moves on to the external secondaries I've supplied.
It looks like the `cloud-early-config` script does the right thing with
dnsmasq.conf, but then the cloud.conf put in /etc/dnsmasq.d/ is incorrect.
I've had a look through the code and that appear to be written by
`systemvm/patches/debian/config/opt/cloud/bin/cs/CsDhcp.py`, but I've been
unable to find where it's being passed the incorrect, non-redundant, IP
information.
