[Oisf-users] Failure when trying to set feature via ioctl for 'eth1': Operation not supported

[Sergey Malinkin]

Hello all.
Test suricata 4.0.5 on VM CentOS 7 on Hyper-V.
Configured span, install suricata from repo.
After launch suricata have a next error message:

*<Warning> - [ERRCODE: SC_ERR_SYSCALL(50)] - Failure when trying to set
feature via ioctl for 'eth1': Operation not supported (95)*

*cat /etc/sysconfig/suricata*
*OPTIONS="-i eth1 -l /var/log/suricata/ --user suricata --set
vlan.use-for-tracking=false --set capture.disable-offloading=true --set
unix-command.enabled=false "*

So, if run *ethtool -K eth1 rx off tx off sg off tso off gso off gro off*
I have next result:












*Cannot change scatter-gatherActual changes:rx-checksumming:
offtx-checksumming: off        tx-checksum-ipv4: off
tx-checksum-ipv6: offtcp-segmentation-offload: off
tx-tcp-segmentation: off        tx-tcp6-segmentation: off
tx-tcp-mangleid-segmentation: offgeneric-segmentation-offload:
offgeneric-receive-offload: off*

On linux kvm all work fine, but with Hyper-v i don't know what doing.
May be have some ideas?
