            Bug ID: 204
           Summary: Crash on Vmware esxi host when dpdk guest reboots.
           Product: DPDK
           Version: 18.11
          Hardware: x86
                OS: Other
            Status: CONFIRMED
          Severity: major
          Priority: Normal
         Component: core
          Assignee: dev@dpdk.org
          Reporter: girish_potti@affirmednetworks.com
  Target Milestone: ---

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 t=
he
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. Power=
ing
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 adap=
ters
running dpdk.

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