Hi,
We have had the same problem in our datacenter. We have a lot of virtual ESXi5 hosts running for training purposes. We had some weird network connectivity issues. After a lot of troubleshooting we found the culprit of the problem:
- All of the virtual ESXi5 hosts had the same MAC address on vmkernel0 interface.
After changing MAC address our connectivity was fully restored. To recreate your "Management Network" vmkernel with a new MAC use the following commands from the ESXi shell:
esxcfg-vmknic -d "Management Network"
esxcfg-vmknic -a -i 10.10.10.10 -n 255.255.255.0 "Management Network"
