在此一个VF处于错误状态期间，所有其他客户将看到与父母相同的数据包。

目前唯一的解决方案是重新启动来宾。

有时会摧毁客人并重新启动它。

The primary issue is after several hours to upwards of a couple weeks a single VF will get into a bad state for a guest and we will see the following errors on the parent and child.

Versions:

Centos = 7.5.1804

Kernel = 4.4.121-1.el7.centos.x86_64 (Current); Tried 3.10.0, 4.4.75, 4.9.52, 4.14.68

IXGBE = 5.3.7 (Current); Tried 5.3.5, 4.2.1-k, ......

IXGBEVF = 4.3.5 (Current); Tried 2.12.1-k, ....

QEMU = 1.5.3 (Current); Tried 2.0.0

Libvirt = 3.9.0 (Current)

On the parent we will see this error:

ixgbe 0000:05:00.0 ethx: 193 Spoofed packets detected

ixgbe 0000:05:00.0 ethx: 45 Spoofed packets detected

ixgbe 0000:05:00.0 ethx: 3 Spoofed packets detected

ixgbe 0000:05:00.0 ethx: 126 Spoofed packets detectedOn the child you will see an increase in dropped packets.

I don't have a way to view the spoofed packets going out, but I can see the incoming packets getting corrupted and dropped by the guest. Best example is an ARP since it will hit every parent, child. (IPs censored)

During the time this one VF is in a bad state, all other guests will see the same packets as the parent. The only current solution is to reboot the guest. Sometimes destroy the guest and start it back up.
