Unable to add KVM-Host on VXLAN Logic structure - Errors
**### On the AGENT side:**
Not sure if this is just related to Ubuntu systems:
there is an error on the management server every time i reload it:
DEBUG:root:execute:sudo /usr/sbin/service cloudstack-management stop
DEBUG:root:execute:sudo update-rc.d -f cloudstack-management remove
DEBUG:root:execute:sudo update-rc.d -f cloudstack-management defaults

Obviously there is no such file: Should I create One?

**### On the management side**, only when i restart the agent:

**### Regarding the VXLAN** i found the Cloudstack does not link the Interface
Loopback to the VXLAN interface,
I did manually and now it propagates the routes
CLOUDSTACK ALONE DOES NOT ADD THE PARENT Loopback interface:
vtysh -c 'show interface vxlan1000'
Interface vxlan1000 is up, line protocol is up
Link ups: 4 last: 2025/04/06 03:16:37.88
Link downs: 0 last: (never)
vrf: default
index 143 metric 0 mtu 9050 speed 0 txqlen 1000
flags: <UP,LOWER_UP,BROADCAST,RUNNING,MULTICAST>
Type: Ethernet
HWaddr: 7e:05:79:2f:33:7d
Interface Type Vxlan
Interface Slave Type Bridge
VTEP IP: 10.23.133.14 VxLAN Id 1000 Access VLAN Id 1
Master interface: brvx-1000
protodown: off
Once I manually Link the parent Loopback interface:
vtysh -c 'show interface vxlan1000'
Interface vxlan1000 is up, line protocol is up
Link ups: 0 last: (never)
Link downs: 0 last: (never)
vrf: default
index 17 metric 0 mtu 9050 speed 0 txqlen 1000
flags: <UP,LOWER_UP,BROADCAST,RUNNING,MULTICAST>
Type: Ethernet
HWaddr: b6:9d:d9:66:b1:60
Interface Type Vxlan
Interface Slave Type Bridge
VTEP IP: 10.23.133.14 Link Interface lo VxLAN Id 1000 Access VLAN Id 1
Master interface: brvx-1000
protodown: off
Parent interface: lo
Is propagating the routes, and I can reach from the remote VTEP
Now the System VMs agent-state shows green
But still the System Vms' Interface name are not populated, should it be
populated ? what is the normal status for this?
Please let me know.
Tata Y.
