NIC attach/detach action fails when FW is enabled
|Category:||Drivers - Network|
|Target version:||Release 4.6|
|Affected Versions:||OpenNebula 4.4|
When FW is enabled, NICs cannot be attached or detached.
NIC detach physically disconnects the interface but the whole action fails with:
[VMM][E]: Error detaching VM NIC
(and ONE still show that interface as connected)
NIC attach doesn't work at all:
[VMM][E]: Error attaching new VM NIC
I'm trying to get more information, the problem seems to be somewhere in chain handling and naming for iptables. Detach seems to fail on iptables clean-up and attach on chain creation.
