Description Roman Hodain 2013-10-02 08:05:33 EDT
Description of problem:
   ovirt-hosted-engine-setup configures the firewall during the installation process in the following way:

# cat /usr/share/ovirt-hosted-engine-setup/templates/
# Generated by ovirt-hosted-engine-setup installer
#filtering rules
-A INPUT -i lo -j ACCEPT
-A INPUT -p icmp -m icmp --icmp-type any -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
#drop all rule
-A INPUT -j REJECT --reject-with icmp-host-prohibited

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Let the ovirt-hosted-engine-setup to configure the IP tables
2. Install the manager

Actual results:
   Host is non responsive and the setup scripts reads:
      Still waiting for VDSM host to become operational...

Expected results:
   Host is UP

Additional info:
We have to open port 54321. The communication does not go via LO device but from vnet0 to rhevm

# brctl show
bridge name	bridge id		STP enabled	interfaces
;vdsmdummy;		8000.000000000000	no		
rhevm		8000.ac162db11b78	no		eth0
Comment 1 Sandro Bonazzola 2013-10-02 08:59:11 EDT
I'm not sure it's actually an ovirt-hosted-engine-setup bug.
ovirt-hosted-engine-setup changes iptables rules only untill the host is added to the engine. 
When it adds the host it should be ovirt-host-deploy that take care to change iptables rules in order to have the host properly configured.
In all-in-one plugin we configure iptables during setup and disable the iptables configuration on host-deploy through SDK. But here we're not disabling that configuration.
Alon can you help figuring out what is happening?
Roman can you attach the log from host-deploy?
Comment 6 Alon Bar-Lev 2013-10-04 17:06:54 EDT
NETWORK/iptablesEnable=bool:'False' - host-deploy will not setup iptables.
NETWORK/firewalldEnable=bool:'False' - host-deploy will not setup firealld.

hosted engine is a new package, does not need errata for specific bugs during its development.
