| − | == VPP_VAGRANT_NICS disappear after "vagrant halt" or "vagrant reload" ==
| + | [[VPP/Troubleshooting/BuildIssues | Build issues]] |
| − | | + | |
| − | More than likely if you've added a NIC via the above env variable, its ended up an orphan after a "vagrant reload".
| + | |
| − | | + | |
| − | Sympton:
| + | |
| − | * "ip -o a" doesn't show any "ethx" type interfaces other than "eth0" mgmt
| + | |
| − | * on VPP startup (assuming emacs gud-gdb) you see:
| + | |
| − | EAL: PCI device 0000:00:03.0 on NUMA socket -1
| + | |
| − | EAL: probe driver: 8086:100e rte_em_pmd
| + | |
| − | EAL: Device is blacklisted, not initializing
| + | |
| − | EAL: PCI device 0000:00:08.0 on NUMA socket -1
| + | |
| − | EAL: probe driver: 8086:100e rte_em_pmd
| + | |
| − | EAL: Not managed by a supported kernel driver, skipped
| + | |
| − | | + | |
| − | Fix:
| + | |
| − | | + | |
| − | * Don't Panic - there is no need to "reboot" or "vagrant reload --provision"
| + | |
| − | * Do following:
| + | |
| − | sudo su
