Hi ovirt users,
=20
I was trying to check on IRC the below, did not get any replies, so sendin=
g this
mail.
Can someone help me understand what could be the issue that causing
my man=
aged host to lose network settings, when i try to discover it from
ovirt-eng=
ine ?
I have to then manually (using a remote console) re-setup the
network.. it=
even overrites my ifcfg-eth0 file
=20
I see a new bridge getting added called ovirtmgmt and route entry corr. to=
that..
the ifcfg-eth0 also has that entry
I feel that ovirt scripts running on the host should atleast take a
backup=
of the ifcfg* files they modify so that in case of issues like these, user
c=
an login via remote console and restore the original ifcfg file.
=20
This is what i asked on IRC... responses appreciated...

deepakcs> Hello, i just configured ovirt-engine and discovering my first m=
anaged host.. got some Qs
<deepakcs> what diff does it make when i select "override
ip tables" check=
box during new Host workflow ?
* djasa has quit (Ping timeout: 480 seconds)
<deepakcs> this is the second time i am discovering this host and everytim=
e
the host discovery hangs during "Installing" and if i check the host, it g=
oes out of network.... has anybody faced this problem before ?
<deepakcs> While discovering the host, the host network ipv4
address is go=
ne ! and thus the host goes out of network
=20
Some more updates..
1) I manually re-setup the host network, made it pingable, esp from the ov=
irt-engine node, and clicked on Re-install on the web gui, this time with th=
e 'override ip tables' check enabled
2) this time it successfully completed the node bootstrap steps (as
seen f=
rom the Events window) and status was Reboot
3) But after reboot the same thing happened.. the host lost ipv4
addr, rou=
te entries are completely gone and onthe web gui the host is seen as
non-res=
ponsive, which is expected bcos the host is not on the network anymore...
=20
what is the reason the above is happening ?
Hi,=20
First, in order to understand the reason for bootstrap failures, please atta=
ch engine.log (ovirt-engine) and node logs (under /tmp/vds_bootstrap.log, vd=
s_installer.log).
Second, what you describe regarding the loss of network could derive from th=
e following reasons:
- host is configured with bonding - but bonding is not configured correctly.=
- NetworkManager interfere with networking config.
- bridge (ovirtmgmt) is not set to with any BOOTPROTO or ONBOOT.
Please attach network scripts (ifcfg-eth0, ifcfg-ovirtmgmt) and /var/log/mes=
sages .
Haim
