SymptomsNetwork of a virtual machine has the following configuration:
- LACP-enabled physical switch
- Two or more Ethernet interfaces on hardware node plugged in to the switch ports
- Two or more NIC adapters in virtual machine are bridged to corresponding physical NICs of the hardware node
- A single bonding interface is created by means of guest OS
CauseBy default MAC filter rejects any traffic which has MAC address which differs from virtual NIC MAC.
ResolutionDisable ARP filter for all NIC adapters of corresponding virtual machine:
~#prlctl set VMNAME --ifname net0 --ipfilter no --macfilter no --preventpromisc no
NOTE: Virtual machine reboot is required to apply the changes.
