Re: [ovirt-users] VDSM Network Bug or Feature?

Hello List, i think i found a nasty Bug (or feature) of ovirt. One of my network cards was set up with dhcp. At this specific time there was not yet a dhcp server set up which could respond to dhcp requests. Therefore my network interface was not able to obtain an ip address. This „failure“ leaded to that my ovirtmgnt bride would not get startet. __Maybe__ because ovirtmgmt is alpha numeric after dbvlan116? Because all my bonding interfaces bond0 and bond1 started just fine. I was able to solve it by moving my /sbin/dhclient to /sbin/dhclient.backup and creating a dummy exit0 bash script as /sbin/dhclient. Then the network startup process seems to progress to my ovirtmgmt interface. From now on i was able to connect and manage my host again and to set up my dbvlan116 interface from dhcp to none. Here is the process list it seems to loop in: root 2554 0.0 0.0 115612 1988 ? S< 10:06 0:00 /bin/bash /etc/sysconfig/network-scripts/ifup-eth ifcfg-dbvlan116 root 2594 0.0 0.0 104208 15620 ? S< 10:06 0:00 /sbin/dhclient -H ovirt-node06-stgt -1 -q -lf /var/lib/dhclient/dhclient--dbvlan116.lease -pf /var/run/ root 32047 0.0 0.0 115348 1676 ? S<s 10:06 0:00 /bin/sh /usr/libexec/vdsm/vdsmd_init_common.sh --pre-start root 32142 1.5 0.0 348460 24952 ? S< 10:06 0:00 /usr/bin/python /usr/share/vdsm/vdsm-restore-net-config Just killing the dhclient does not seem to work. It keeps retrying. I reported a bug before, but maybe its better to discuss it here first and explain the bug properly to that the Bugtracker guys know what i mean and what the problem is? :)

Maybe its best to start the ovirtmgmt interface first? Otherwise a wrong configured interface will lock you out of the system.
