Hi.
Is it possible through engine to specify configuration parameters for
network interfaces that must be passed through on initialization? For
example, I need em1 and em2 configured with LINKDELAY=10. I can add
it after the fact, but I don't want to do that. I want vdsm to
configure the interface with that setup already the first time.

Argh x 10.
I have 2 x Intel 10G ports on an Intel X540 adapter. If I kickstart a
brand new host, and configure em1 with LINKDELAY=10, the system boots,
and gets an IP via DHCP. If I then add the host through engine, vdsm
reconfigures em1 and removes LINKDELAY. Now, since the network adapter
takes a little extra time to initialize, install fails. If I add
LINKDELAY=10 back manually to
/etc/sysconfig/network-scripts/ifcfg-em1, VDSM will happily remove it on
the next reboot. If I modify
/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt, and insert:
linkdelay:10, and reboot, vdsm fills it in for me as I'd expect, but
it's too late - engine thinks the install already failed! I can delete
the failed install host, and re-do the install. This time it will
work, but then my instructions are messy... Install the host, let it
fail, modify a file manually, re-install... clearly, not clear!!
Finally, as a last attempt, I've tried to copy
/var/lib/vdsm/persistence/netconf/nets and bonds to the host during
kickstart, hoping that when vdsm initialized, it would see those files
there, and I'd have all 4 networks configured already for me. The result
is weird. ovirtmgmt configured fine including LINKDELAY=10.The
other ones did not.I suspect it's a bad idea to write directly to
/var/lib/vdsm/persistence/netconf ... What I want to do doesn't seem
like it should be too complicated...
Ideally, when you add a host through engine, you should be able to
specify custom network parameters. Likewise, when you add the other
interfaces, you should be able to do the same. Any ideas how to solve
this problem?
