i am running ESX 4.1 OS and recently I host vmotion 100 Vmachine from existing hosts to new hosts, all vmachine are working fine except one machine. After migration, the machine lost netwrok connectivity. I tried to delete the NIC card, reboot and added and configure IP, but still only can ping the IP itself, can not ping gateway.
I also tryied to disable the NIC and added new NIC and configure with IP, still no help.
Tried to configure the machine using other range of VLAN IP, no help.
checked system event log and did nto noctice anything special.
Now even I vmotion back to the original host, no connection too.
Never encounter such problem before, so strange, did any one have some idea about this?
Many thanks in advanced
