As recently discovered, newly applied permissions are not updated on already running processes, the MicroOVN install starts the daemon and then gives it the needed permissions, so we must restart the daemon to be able to use them. This only affects things that require specific linux capabilities to be enabled compared to just file permissions, such as netlink connections for devlink in the upcoming dpu work. This will not affect microovn installed from store as connections are applied before processes start. Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit ac1a0cc)
Setup Build MicroOVN workflow to be used in test.yaml and future workflows that build the MicroOVN snap. Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit 906578f)
Adds DPU setup to join and bootstrap, this will detect if its running on a DPU and return the PCI address, then it will extract the serial number and properly insert it into the ovn-cms-option. Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit ef8e289)
Iterating through maps is non deterministic, so this unit test only passes half the time, which means builds fail half the time, so we need to remove it. In the real world we likely shouldnt have multiple valid ports, so this wont be an issue, and even if it comes up just using the first one we get should work fine. Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit 7589627)
In recent research with real hardware we have found our previous assumptions to be incorrect, so we are updating it to be controller = 1 and pcipf OR pcivf in the devlink port output[0].

Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit 61f3938)
MicroOVN will now check for a file, which if it finds it will allow the user to force install microovn alongside system OVS. The file should only exist if the user *really* knows what they are doing and intentionally creates it. Signed-off-by: MJ Ponsonby <mj.ponsonby@canonical.com> (cherry picked from commit 0392316)
