What does the VM misbehavior code 0x18000000 represent?

Hi!

I am using latest IGB driver(5.3.5.3) for Intel I350-T2 adapter.

Enabled IOMMU, created two VFs ('modprobe igb max_vfs=2'), and added the first VF as a passthrough device to a guest VM.

Installed latest IGBVF driver(2.3.8.2) in the guest.

Whenever I transmit packets from the guest, I observe the following error in dmesg of the host.

"igb 0000:02:00.0 p4p1: VF 0 misbehaved. VF queues are disabled. VM misbehavior code is 0x18000000"

Following this error, the host machine hangs immediately.

Could anyone please explain what does the code '0x18000000' represent and how to fix it.

Thanks much in advance!

Regards

Karthik

Hi, Good day to you.

I did use Virt-manager only. BTW, what does 'VM misbehavior code is 0x18000000' convey? Any problem with my VM?

Thanks

Hi Karthik,

 

 

Thank you for the reply. Please provide information below for better investigation:

 

 

1. Server make, model and BIOS version numbers.

 

2. Linux kernel dmesg log.

 

3. Igb PF driver version.

 

4. KVM or Xen logs.

1. Server make, model and BIOS version numbers.

Please find the attachment containing the output of dmidecode

2. Linux kernel dmesg log.

Please find the attachment.

3. Igb PF driver version.

latest igb driver - 5.3.5.3

4. KVM logs

I am not sure what do you exactly need. Could you please help me by directly specifying the names/locations of the files you need?

In between your analysis, if you could give a clue on what does 'VM misbehavior code is 0x18000000' convey, I will be able to help you in case if this is a problem in my VM.

Regards

Karthik

Hi Karthik,

 

 

Apologize for any delay. The "misbehavior code 0x18000000" means PF driver detected a MDD event. MDD is Malicious Driver Detection feature. You are using sourceforge igbvf driver that has not been updated quite a while.

 

 

Please use the in-box (aka in-kernel) igbvf driver and retest. In-box (in-kernel) igbvf driver is updated more frequently than the sourceforge driver.

 

 

Thanks,
