    I have setup vCP & vFP using  vmx Junos: 19.4R3-S8.6. if I setup all the interface using E1000 and lite-mode, all just working fine.
    But when I change all the interface to use the SR-IOV, the FPC can not be online, it always on testing.
    does any one have success setup using SR-IOV on ESXI?

    I use Intel NIC X550, ESXI 6.7U3, I have follow the juniper kb Enabling SR-IOV for VMware
    Juniper remove preview
    Enabling SR-IOV for VMware
    You can configure VLAN tagging on SR-IOV interfaces on vMX instance deployed in VMware ESXi host with the following steps:: We've used the hardware and software combination for the following procedure: VMware ESXi version 6.5 Update 3 i40en driver version 1.10.6 for Intel 700 Series network adapters Firmware version 7.20 for Intel 700 Series network adapters Enter the CLI configuration mode after logging in to the vMX.

    Testing is what I have found to be a normal and functional state for vMX FPC's (linecards)...
