HP DL360 G6 + NIC Intel 82576 - passthrough not work

[arcio]

Hi :smileywink:

In vmware ESXi 5.1 on HP DL360 G6 can not run passthrough for the network adapter. NIC has 82576 chipset and supports Single Root I/O Virtualization. Vmware still want me to reboot a host to start running a network adapter in passthrough mode. After rebooting is same. Here are some logs from dmesg:

In addition, I attach screenshots from vmware:

DirectPath I/O is supported...

After rebooting I have a same info: "This device needs host reboot to start running in passthrough mode" :smileysad:

Thank you kindly for your help.

Best regards

I have the same issue on a Dell server. Broadcom NIC in other slot is fine but none of the 4 Intel NIC`s (Quad Intel PRO ET) will work in pass through out of the box.

Hi,

I have the same issue on asrock whitebox server with HP NC364T PCI Express Quad Port Gigabit Server Adapter. I have found the solution on VMware Technologies Blog: PCI Passthrough (Direct-IO or SR-IOV) with PCIe devices behind a non-ACS switch in vSphere.

Select the host and navigate to Configuration > Advanced Settings (Software) > VMkernal > Boot. Search for a parameterVMkernel.Boot.disableACSCheck and enable the check-box.

It has worked for me. I have dedicated the network cards to nested esxi VMs.

This may be a few years old now but is still valid on ESX 6.0U2 - I've just used Peter's suggestion to enable some GPU passthrough on a DL380G9 where it kept saying that I needed to reboot the host even after rebooting. Enabling VMkernel.Boot.disableACSCheck did the trick.

[AllanHouston]

I'll second that, just managed to get passthrough working on an old HP Z210 using Peter's VMkernel.Boot.disableACSCheck solution - really, really useful post.

I think its fair to say I'd have never figured that out on my own!

[rigerwu]

Really thanks, Dude. It did work for me.

@peter_golis Just wanted to say thank you, as well. Enabling VMkernel.Boot.disableACSCheck allowed me to pass through my quad port HP (rebadged Intel) NIC.

[claudiovt]

Just for the record.

Still works with ESXi 6.5 U2 custom HPE image.

Server DL360 Gen 9 . Tried to passthrough NIC model NC364T.

Just wanted to confirm this worked for me with a Dell H092P 4-port nic on a whitebox AsRock J3455B-ITX I'm putting together for a needy cyber security student (installing OPNSense and wanted an isolated NIC for WAN).  Thanks!
