Dears, I use sr-iov vf for docker network device by kubernetes, but there has a bigger probability of system reboot
syslogs record nothing, and only happened when there are release & allocate VF
what should I do for solve this problem?
My environment:
BIOS already enabled VT-d and SR-IOV global enable
os is ubuntu 16.04, kernel version 4.10, options is
BOOT_IMAGE=/vmlinuz-4.10.0-35-lowlatency root=UUID=xxxx ro cgroup_enable=memory swapaccount=1 intel_iommu=on iommu=pt
set max_vfs to 63
echo 63 >/sys/class/net/enp4s0f1/device/sriov_numvfs
