Hi Everbody I have a very odd issue on the KVm host where both agent and management is installed.
Recently I have tried to mirror outbound smtp traffic from a test vm to IFB device to analyze it using zeek for spam filtering. I did the mirroring using tc filters. Everything was working before I added a custom libvirt hook inside */etc/libvirt/hooks/qemu.d* and restarted libvirtd service to add tc filter rule to any new VM being created. Once I restarted libvirtd host freezed and afterwards everytime host boots it freezes not accepting any input even in emergency mode. When I enter emergency mode, it only allows me a few seconds to issue a command and then freezes. This happens even if I mask NetworkManager, libvirtd and cloudstack-agent during boot to disable any service that cause system freeze I have reverted back everything but still kernel freezes As I needed to analyze existing smtp traffic I needed to do on the production server but everything is down. Please help! Best Regards
