-| Configure guest VM with linux bridge using SMT connected via vhost-user
-| | [Documentation]
-| | ... | Start QEMU guest with two vhost-user interfaces and interconnecting
-| | ... | linux bridge. Qemu Guest uses 2048M.
-| | ...
-| | ... | *Arguments:*
-| | ... | - dut_node - DUT node to start guest VM on. Type: dictionary
-| | ... | - sock1 - Socket path for first Vhost-User interface. Type: string
-| | ... | - sock2 - Socket path for second Vhost-User interface. Type: string
-| | ... | - vm_name - QemuUtil instance name. Type: string
-| | ... | - skip - number of cpus which will be skipped. Type: int
-| | ... | - count - number of cpus which will be allocated for qemu. Type: int
+| | ... | _NOTE:_ This KW expects following test case variables to be set:
+| | ... | - cpu_count_int - Number of Physical CPUs allocated for DUT.
 | | ...
 | | ... | *Example:*
