Description

When adding a 3rd or more VMXNET3 interface in vSphere 6.7(vm version 14) and 6.7u2 (other versions not tested) the adapter installs then detaches immediately. After reboot only first two nics are still available, no entries in DMESG pertaining to VMX2, or in pciconf.

From DMESG when adding a 3rd NIC:
vmx2: <VMware VMXNET3 Ethernet Adapter> at device 0.0 on pci6
vmx2: Ethernet address: 00:50:56:9e:82:ac
vmx2: detached
pci6: detached

I have 3 VMX connected and all seems to be working. No issues.

I appear to have made a typo. It should be more than 3 adapters. I checked ran into it again a week or two ago, it was the same for E1000E also.

#4 Updated by Patrick Sanderson 3 months ago

I have run into this bug again with a VM and 2.4.5. I am unable to add a second interface at this point, they show up in messages as attached, then detached. I have preserved the VM and can supply credentials as necessary.

The VM was created with 5 VMXNET3 adapters successfully, but the ordering was wrong, so I removed 3. I then removed LAN from assigned interfaces in pfSense GUI and which point it dropped from the VM, any attempts to re-add any new NICs show attach/detach, reboot doesn't re-initialize any of the added nics.
