Bug Description
The SR-IOV interface configuration is currently done in a one-shot mode. Either after installation of charm or after change of config option 'sriov-numvfs'.
After a reboot of the node the charm is running on, none of this will happen and the systems SR-IOV interfaces will be left unconfigured.
Other means of doing this:
- kernel or module parameters (ixgbe.max_vfs=N)
- separate init script
- rc.local
- use hook that most likely will be executed after reboot
summary: |
- SR-IOV interface configuration is not preserved accross reboots of unit + SR-IOV interface configuration is not preserved across reboots |
