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=
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... =20 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=

=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
