Basically I enabled SR-IOV on the only two pNIC's I had in my ESXi host in my lab. This doesn't necessarily cause a connectivity problem, but the ESXi management agents did not like this at all. Meaning I could connect to my hosts, as evident in the error message, but the agents basically broke once SR-IOV was enabled on the only two physical uplinks I had.
Unfortunately, the only workaround I've found is to:
- "Reset System Configuration" from DCUI
- This basically bring ESXi back to default install config. root password is blanked out, etc. etc.
- Re-Deploy the host.
SR-IOV effectively changed my CNA cards to NIC adapters only.
