OVS crashes if there are multiple conflicting installations. As such, the charm currently errors out when detecting system OVS services. The problem is that with DPDK, we expect OVS bridges and bonds to be preconfigured through MAAS/Netplan, which currently use system (deb) OVS packages. Instead of erroring out, we'll stop and mask system OVS services, then reapply Netplan to move the OVS bridges to the snap based OVS installation. Netplan is expected to contain the following patch: https://github.com/canonical/netplan/pull/549 Note that any configuration defined in the system OVS db that's not set in Netplan will be lost.
