    I have set up vMX with version 17.1 but not able to see GE-* interfaces, need your help to troubleshoot this problem.

     

    ping from VCP to VFPC is working.
    lx@junos-176-98> ping 128.0.0.16 routing-instance __juniper_private1__

    Hi

    Please can you confirm the CPU and Memory that are allocated to the vFPC. If you login to the console on FPC do you see error messages (also see logs is /var/log).

    If you do no meet the vCPU requirements for performance mode, please change to lite mode FPC

    Thanks Matt, After I set vMX to lite mode and enlarge the vCPU number to 3 and memory size to 16G, it is now working as expected. Really appreciate your assistance on it.

    Hi mdinham,
    My laptop:
    - Processor 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz
    - Installed RAM 16.0 GB (15.7 GB usable)
    I set up eve (RAM 10G, vCPU 8), use vMX (kvm version 17.3R3-S9.3). 
    I create a topo included 2 vMX, assign IP address to these interfaces and ping each other but I see that RTT is too large.

    And I always face the issue "Not able to see Ge-* interfaces".

    I tried to set lite-mode for FPC but can't resolve them (ping too slow, loss packet, ...).

    Can you help me on these issues?
