Whiteboard:
Fixed In Version: kexec-tools-2.0.0-300.el6.1 Doc Type: If docs needed, set a value
Doc Text:
When the kexec-tools was used on a bridge device containing a tap interface member connected to the OpenVPN software, the kdump mechanism failed to start due to the missing /etc/sysconfig/network-scripts/ifcfg-* configuration file for the tap interface, which is one type of the unsupported logical network interfaces. Because the bridge is able to work without the logical member, if it contains at least one physical interface, with this update, kdump skips the unsupported logical interface. As a result, kdump now starts as expected in the described situation.

Hi PM,

The build for this bug fixing can't be found in errata when I tried to save the build. Below is the error message in errata.

 RHBA-2016:24810-02 kexec-tools bug fix and enhancement update
Build Search Errors:

kexec-tools-2.0.0-300.el6.1: Error retrieving build kexec-tools-2.0.0-300.el6.1: Couldn't find BrewBuild with nvr = kexec-tools-2.0.0-300.el6.1

Any idea for this?

Thanks

I would like to invite Xunlei to have a look at this because he worked on the original bug fix.

Thanks
