Description haiyang,dong 2012-12-13 06:53:01 UTC 
Description of problem:
when configured kdump on Dell smbios 2.6+ machine via NFS/SSH to saving the dump file to remote nfs/ssh server.
There is no dump file in remote nfs/ssh server.

Also make a summary here:

1.configured kdump via NFS/SSH on 6.3 build

normal machine- 100% saved dump file in remote nfs/ssh server
Dell smbios 2.6+ machine - 100% saved dump file in remote nfs/ssh server
HP biosdevname 2.6 - 100% saved dump file in remote nfs/ssh server

2.configured kdump via NFS/SSH on 6.4 build

normal machine- sometimes could save dump file in remote nfs/ssh server(may the root cause is that Missed the line "link_delay 60" in /etc/kdump.conf)
Dell smbios 2.6+ machine - 100% missed dump file in remote nfs/ssh server
HP biosdevname 2.6 -   80% can send dump into remote nfs/ssh server

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20121206.0.el6

How reproducible:
100%

Steps to Reproduce:
1. Install rhev-hypervisor6-6.4-20121206.0.el6
2. Configure the Kernel Dump with NFS/SSH in the TUI.
3. echo c>/proc/sysrq-trigger to make the system coredump.
4. check the remote nfs/ssh server folder

Actual results:
1. There is no dump file in the remote nfs/ssh server.

Expected results:
There is dump file in remote nfs/ssh server.

Screenshot showing that /dev/HostVG/Data can not be found

Seems to be that the VGs are not found/nodes created.

An update from 892703 comment 7 : There is a fix for this problem but afterwards the bridge has problems to retrieve an IP address (seems to be a different bug, like 817157).
