VMware: ESXi 6 503 Service Unavailable endpoint: [N7Vmacore4Http16LocalServiceSpecE:0x1f098b08] _serverNamespace = / _isRedirect = false _port = 8309)
Summary:
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.

Workaround:
Unfortunately, the only workaround I've found is to:
SR-IOV effectively changed my CNA cards to NIC adapters only.
Config:
ESXi 6.0 Build 5050593
Dell FX2 - FC630 - Qlogic 57810 adapters

Workaround:
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.
