If vm uses the same ip range 192.168.122.0/24, there will be some issues. In some cases, if we run tcpdump inside vm, we will see the ip of kvm hypervisor as source ip. > CloudUtils getDevInfo function only checks for KVM bridgePort and not OVS > ------------------------------------------------------------------------- > > Key: CLOUDSTACK-10081 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10081 > Project: CloudStack > Issue Type: Bug > Security Level: Public(Anyone can view this level - this is the > default.) > Components: cloudstack-agent > Affects Versions: 4.11.0.0 > Reporter: Sigert Goeminne > Assignee: Sigert Goeminne > Priority: Major > Fix For: 4.11.0.0 > > > CloudUtils getDevInfo function only checks for KVM bridgePort and not OVS.
