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 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.
