Description girish potti 2019-02-01 18:18:19 CET 
Running Vmware esxi 6.5 with i40en driver 1.7.11 . Guest running debian8.0 with either dpdk 18.05.1 or dpdk18.11 (lts) .

When the guest is rebooted occasionally we see the crash on esxi host and the guest is shut down.

vmware-9.log:2018-09-24T00:57:09.434Z| vmx| I120+ PCI passthru device 0000:03:0e.0 caused an IOMMU fault type 4 at address 0x7881ba04e3000. Powering off the virtual machine. If the problem persists please contact the device's vendor.```

The Device 0000:03:0e.0 is a fortville 25g nic. The guests have vfs as adapters running dpdk.

If we dont have dpdk running on guest(just the linux vfs driver)  this issue doesnt happen on host.

Anything that crashes a host is a host bug. The host can never trust the
guest to be well behaved. These are serious  often with security
implications. Hopefully VMware will or has already addressed it.

The i40e host driver is causing this.Vmware just shuts the card off when i40e host driver detects the problem.
I think Intel should look at that too.
