Intel x710-t2l Problems

@olivierlambert

Good morning!

I've performed a clean v8.3 install with all updates.

As before, the Intel x710-DA4 works when added to a vm in Xen Orchestra. I'm still unable to do a pci passthrough to a TrueNAS vm. I can pass LSI hba and Intel datacenter nvmes.

The Intel x710-T2l is listed via lspci but is otherwise unresponsive.

Your thoughts?

Hi!

What do you mean by "unresponsive"?

@olivierlambert

Good morning!

I've created a Debian 13 vm with x710-T2l as the network device.

When I try to install Debian 13, the installer fails when trying to acquire a DHCP address.

My original plan was/is to build a pfSense router/firewall using the x710. The installer configures the interfaces (WAN/LAN) but fails when trying to access the internet.

The XCP-ng v8.3 host is using the alt i40 driver.

And if you add a fixed address, does it work?

@olivierlambert

I ran through the install with a fixed address without success.

I've attached some screenshots for your perusal.

Is your card having a recent firmware? I don't know why a passthrough NIC wouldn't work

try to disable tx/rx offload from xcp-ng side.

1. get VIF list of your VM

xe vm-vif-list uuid=VMUUID

2. disable features for each VIF

xe vif-param-set uuid=VIFUUID other-config:ethtool-tx="off"
xe vif-param-set uuid=VIFUUID other-config:ethtool-rx="off"

3. reboot VM

@olivierlambert
Yes, there has been a recent firmware update.

Here is the info on the x710-T2l:
[08:19 xandria ~]# ethtool -i eth9,
driver: i40e
version: 2.26.8
firmware-version: 9.54 0x8000fb5f 1.3800.0
expansion-rom-version:
bus-info: 0000:41:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

The x710-DA4, which is assignable to a vm via Xen Orchestra but not assignable via pci passthrough, is on a much older firmware rev:
[08:24 xandria ~]# ethtool -i eth4
driver: i40e
version: 2.26.8
firmware-version: 6.01 0x80003484 1.1747.0
expansion-rom-version:
bus-info: 0000:04:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Hi!

Thanks for your input. I set the vif parameters as suggested and am still unable to ping the gateway.

@olivierlambert

I realize this is an older topic and I'd like to share you with what I have learned.

The x710 series has a reputation for being picky about driver and nvram versions.

According to the "332191_Intel Ethernet Controller X710-XXV710-XL710 Feature Summary_Rev5_12" publication, page 34, the closest match for XCP-ng's intel-i40e-alt.x86_64 (version: 2.26.8) is nvram 9.52.

I flashed both the x710-T2l and the X710-DA4 to 9.52 and have success passing the x710-DA4 through to a vm.

I haven't tried to do a passthrough with the x710-T2l; I've got PfSense running using XCP-ng's vlan feature and some tuneables in PfSense and am reluctant to rock the boat.

I'm including a snapshot of page 34 of the Intel pub for your review.

Best regards!

Out of curiosity, is there anything reported by the linux driver that would allow make the situation obvious?

[wlp94114]

@yann Hi yann,

Sorry for the radio silence. Have been away.

How would I check for that?

[yann]

@wlp94114 for example, did you get any warnings in the kernel logs about the firmware version mismatch?
