Hi.

We updated Opennebula to last stable version…

now, we cant reserve ip or create reservations… because we found an error after that…

“[one.vn.reserve] No VN\_MAD in template for Virtual Network.”

At the beginning I thought it would be a failure only at sunstone… but thats not correct, the error persist using onevnet.

for example: onevnet show 14 (only header)

```
<VNET>
  <ID>14</ID>
  <UID>0</UID>
  <GID>0</GID>
  <UNAME>oneadmin</UNAME>

```

i can look the vn\_mad set to dummy… well i try to create the reserve like that.

> onevnet reserve 14 -a 1 -s 1 -i 10.112.0.IP -n alfeijoo-devel-10.112.0.IP

And have the same error…

[one.vn.reserve] No VN\_MAD in template for Virtual Network.

and oned.log

we can live without pci assign using sunstone… but not without reservations…

It looks like for some reason the upgrade process didn’t set the VN\_MAD. Please update your vnets to set the proper VN\_MAD in each of them.

Hi Tino.

Did you said that i need to set manually the vn\_mad=dummy as a atribute? or directly in the database?

You can use a “onevnet update” to add the VN\_MAD.
