Description Sachin Ghai 2016-03-21 08:46:45 UTC

Description of problem:
I was trying to configure alias and vlan interfaces on rhel7 host using static subnet. Host was provisioned successfully, but none of the interfaces configured.

I checked the interface configs are found that device names were incorrect.

Alias interface config file named ike:
 /etc/sysconfig/network-scripts/ifcfg-_0

[root@sghai ~][root@sghai ~]# cat /etc/sysconfig/network-scripts/ifcfg-_0  | grep DEVICE
DEVICE=:0


vlan inteface config file named as:
/etc/sysconfig/network-scripts/ifcfg-.1

[root@sghai ~]# cat /etc/sysconfig/network-scripts/ifcfg-.1  | grep DEVICE
DEVICE=.1



Version-Release number of selected component (if applicable):
sat6.2 beta snap4

How reproducible:
always

Steps to Reproduce:
1. configure alias and vlan interfaces on rhel7
2.
3.

Actual results:
incorrect device names in alias and interface config files 


Expected results:
Device names sould be correct

Comment 8 Sachin Ghai 2016-04-07 10:07:38 UTC

Verified with sat6.2 beta snap6.2

when we provision a host by adding a alias interface, host provisioned successfully but with incorrect alias interface name:


[root@alias network-scripts]# cat ifcfg-_0
BOOTPROTO="none"
IPADDR="192.168.100.120"
NETMASK="255.255.255.248"
DEVICE=:0
ONBOOT=yes
PEERDNS=no
PEERROUTES=no
TYPE=Alias


however, if I rebuild the same host then interface comes up correctly:

[root@alias network-scripts]# cat ifcfg-eth0_0 
BOOTPROTO="none"
IPADDR="192.168.100.120"
NETMASK="255.255.255.248"
DEVICE=eth0:0
ONBOOT=yes
PEERDNS=no
PEERROUTES=no
TYPE=Alias

same issue with rhel6 host.

Comment 10 Sachin Ghai 2016-04-11 07:32:01 UTC

Okay, Marek and I worked together to find the root cause of issue. Thanks Marek for your help.

Finally, we got to know that user needs to specify the identifier for first interface.

when we provision a virtual host from satellite6, webUI doesn't set the identifier for first interface. However, when we create alias of first interface, we need to specified the identifier under "attached_to" otherwise, alias interface won't be configured and it fails silently.

However, UI should raise a validation error for alias interface, if user forget to set the identifier for first interface.  I'll file a new bz.

Comment 11 Sachin Ghai 2016-04-11 10:47:39 UTC

By mistake, closed this bz. Moving this back to ON_QA so that I can move it to verified state it.

Comment 12 Sachin Ghai 2016-04-11 11:05:42 UTC

As per comment10, original issue has been fixed. Moving this to verified. I can create virtual interfaces on rhel6 and rhel7 host.

Please see the screenshots for verification.
