But with oVirt it fails on a server with 4 physical interfaces, but
only two connected, and return an error:
You want that eth0 and eth1 are UP, and eth2 and eth3 are DOWN?Yes.snmptable XXX IF-MIB::ifTable | less
SNMP table: IF-MIB::ifTable
ifIndex ifDescr ifAdminStatus ifOperStatus
1 lo up up
2 eth0 up up
3 eth1 up up
4 eth2 up down
5 eth3 up down
24 ;vdsmdummy; down down
25 vnet0 up up
And indeed on the server:
ip link show eth2
4: eth2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state
DOWN mode DEFAULT group default qlen 1000 link/ether
40:a8:f0:30:81:1a brd ff:ff:ff:ff:ff:ff
looks like eth2 is DOWN, as expected.It's in state DOWN, but marked UP anyway.A really DOWN interface is shown as (on another server, not an ovirt host):4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000link/ether a0:d3:c1:fa:8c:8a brd ff:ff:ff:ff:ff:ff
eth2 seems to be in state DOWN, which seems to be reflected in
ifOperStatus.Yes it match. The state is reflected in the ifOperStatus. The ifAdminStatus match the UP in the <...>
Is the issue that ifAdminStatus is up for eth2 and eth3, but you want
it to be down?That's it. I never ask it to be in such state.
