Virtual network hangs in status LOCK_CREATE after VN creation

Community Support Network
1

Dear all,

I would appreciate any help on the following issue.
As soon as I create virtual network (VN) in configuration as below the status of VN is LOCK_CREATE with 0 leases:

NAME            ="priv"
DESCRIPTION     = "A private network for VMs"
VN_MAD          ="dummy"
BRIDGE          ="br0"

AR=[TYPE="IP4", IP="10.55.9.1", SIZE="254"]
AR=[TYPE="IP4", IP="10.55.10.1", SIZE="254"]
AR=[TYPE="IP4", IP="10.55.11.1", SIZE="254"]

NETWORK_ADDRESS = "10.55.8.0"
NETWORK_MASK    = "255.255.252.0"
DNS             = "8.8.8.8"
GATEWAY         = "10.55.8.1"

There are no errors in the oned.log.

If I do ‘onevnet recover <VN_ID> --success’, status is changed to READY, but if I do 'onevnet delete <VN_ID> the status hangs in LOCK_DELETE. It seems like the problem with driver operations.

OpenNebula version is 6.4.0 CE on AlmaLinux 8.7 x64 (FN and CNs).

I was not able to find any related issue in the Known Issues.

Can you post the output of onevnet show -j <vnet_id> ?

Hi @knawnd,
I’ve double check that the feature is working in CE version for dummy driver.

Please, can you check the output in /var/log/one/oned.log at the time the VN is created?

Here it is:

I see no errors in oned.log file related with a vnet creation.

It seems around VNET creation there is the following error message:

[Z0][IPM][E]: Unable to find IPAM Manager driver

In the oned.conf the corresponding to IPAM driver section is commented:

#IPAM_MAD = [
#    EXECUTABLE = "one_ipam",
#    ARGUMENTS  = "-t 1 -i dummy,aws,equinix,vultr"
#]

IPAM driver related files are in place:

The reason of the problem was in that part (quoted above). It needs to be uncommented.
