Hello Folks,
I hope everyone is doing great…!
So recently i was testing the feature of importing the unmanaged instance from
VMware to cloudstack which is working smoothly. So I have a unmanaged instance
running in the VMware, I have deleted the NIC from vCenter itself (Before
importing it into the CloudStack. I am able to import the instance and able to
add a NIC from cloudstack itself, i.e I have added a NIC from a VPC Tier, But
what I have observed that it doesn’t configure it to the default NIC - Which
means it doesn’t put proper routes under the VM because ACS consider it as a
secondary NIC.
First I looked at the vm_instance table - private_mac_address and
private_ip_address is kept empty. Then I have stopped and start the instance,
After it both rows got populated. Now whenever I tried to set this as a default
NIC, it always give below error -
`Failed to find a Nic profile for the existing default network. This is
bad and probably means some sort o configuration corruption. `
The output of my Nic table is -
mysql> select * from nics where instance_id = '1917' \G
*************************** 1. row ***************************
id: 5306
uuid: db50625f-65f8-40a1-8931-4a696ae29462
instance_id: 1917
mac_address: 02:00:3e:c4:00:07

removed: NULL
ip6_gateway: NULL
ip6_cidr: NULL
secondary_ip: 0
display_nic: 1
1 row in set (0.00 sec)
Then I tried to update the row - default_nic = 1,
mysql> update nics set default_nic = 1 where id = '5306';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
then it started working properly, Now if I add another network to this VM and
also able to make it default as well. So is this correct way to make it
working or should I need to take care some other parameters so that it can be
done from UI as well.
