What kind of proof are you looking for? > I tried this with working Ubuntu 17 on WS2016. It boots if the failover driver is configured in (as module). But if the configuration has: $ grep FAILOVER .config # CONFIG_NET_FAILOVER is not set CONFIG_MAY_USE_NET_FAILOVER=y The netvsc driver fails on boot with: [ 0.826447] hv_vmbus: registering driver hv_netvsc [ 0.829616] scsi 0:0:0:0: Direct-Access Msft Virtual Disk 1.0 PQ: 0 ANSI: 5 [ 0.836291] input: Microsoft Vmbus HID-compliant Mouse as /devices/0006:045E:0621.0001/input/input1 [ 0.839139] hid-generic 0006:045E:0621.0001: input: <UNKNOWN> HID v0.01 Mouse [Microsoft Vmbus HID-compliant Mouse] on [ 0.964897] hv_vmbus: probe failed for device 849a776e-8120-4e4a-9a36-7e3d95ac75b3 (-95) [ 0.968039] hv_netvsc: probe of 849a776e-8120-4e4a-9a36-7e3d95ac75b3 failed with error -95 [ 1.112877] hv_vmbus: probe failed for device 53557f8e-057d-425b-9265-01c0fd7e273e (-95) [ 1.116064] hv_netvsc: probe of 53557f8e-057d-425b-9265-01c0fd7e273e failed with error -95 The system has two virtual networks. eth0 is on vswitch for management. eth1 is on vswitch with SR-IOV for performance tests. You probably need to just put the failover part in net/core and select it. It is trivial to get an evaluation version of Windows Server 2016 and setup a Linux VM. Please try it. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
