Today I vmotioned 5 MS SQL 2005 servers over to a new DRS Cluster. All SQL servers use the "Production_LAN" network and a single virtual NIC of type "VMXNET 3".

The first 4 SQL VM (Windows 2003 Standard or Enterprise x32 bit) vmotioned over without a hitch.

The last SQL VM I vmotioned (Windows 2003 Standard x64 bit R2) vmotioned over without error, but I upon completion, I could no longer ping the VM. I went into the VM and could not even ping the gateway, however I could ping the loopback. This SQL server is extremely busy in comparison with the previous 4 VM's. I restarted the server and it came back up with the virtual nic working just fine.

The build of both servers (vmotioner and vmotionee) is ESX 4.0.0 175625 - So, pre-update 1.

Should I suspect the network switch/VM for possibly not updating the mac table on the switch?

Anybody else ever have this issue or know what may have caused it?

Thank you!

Why is the vSphere console view so slow?

Hi, Why is the Console view on the vSphere client so slow? It's a real shame because it's a shame to have to establish an RDP session every time you work on one of the VMs because of the speed of the console (I saw a tool to right click and open an RDP session to a VM in vSphere Client/ESX but this… >>> More
