            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: [email protected]
          Reporter: [email protected]

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 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.
