when a shared network is secondary the default gateway gets overwritten by a bogus one
dnsmasq does the right thing and replaces it with its own default which is not good for us
so check for '0.0.0.0'
CLOUDSTACK-9598: wrong defaut gateway for the nic in non-default network when guest VM has nic's in more than one guest network set the tag for each host in /etc/dhcphosts.txt, and use the tag to add exception in /etc/dhcpopts.txt to prevent sending default route, dns server in case if the nic is in non-default network
this was the behaviour with edithosts.sh prior to 4.6

CLOUDSTACK-9598: wrong defaut gateway for the nic in non-default network
Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com>
when guest VM has nic's in more than one guest network set the tag for
each host in /etc/dhcphosts.txt, and use the tag to add exception in
/etc/dhcpopts.txt to prevent sending default route, dns server in case if the nic is in non-default network
this was the behaviour with edithosts.sh prior to 4.6
added new test case test_router_dhcp_opts to test DHCP option file use of cloudstack
The VR executes a ip route flush command as part of configurations. This command performs a
DNS lookup on the VR hostname. Since the VR does not have a DNS entry, the ip command would
wait 5 seconds before timing out and executing the flush operation. This fix adds the VR
hostname to /etc/hosts mapped to 127.0.0.1 to answer the DNS lookup – reducing the
execution time.
- It was working before because the Routers were restarting about 10 times for each operation
e.g. adding a VM to a network ot acquiring a new IP.
- Adding stat_rules of internal LB to iptables
We needed one extra rule in the INPUT chain
Fixed failure on using eth10 (which CS now supports)
Refactored CSForward to us CsInterface object instead of teh way it was kludged together
Fixed hex conversion for device numbers and iptables marks
Fixing assign IPv4 on GuestNetworkGuru.java
Fixing getRouters() on VpcVirtualRouterElement.java
Fixing Fixing paths on keepalived.conf.templ
Refactor on the other files
firewallrules implemented sperately from networkacl (ugly but best that can be done ATM)
Some refactoring in CsDHCP as it made no sense to do it that way anymore
processmonitoring implemented
Domain not correctly sourced in VR
