ESX4.0 gateway not pinging.

[RahulMM]

Hello Guys,

I have an ESX server 3.5 U4. To get some hands on ESX4.0 , I presented a 50 gb LUN to my ESX3.5 and created a VMFS datastore on it. I successfully installed ESX4.0 on this 50 gb data store. So in a way I have a virtual ESX4.0 server. After installation I tried to ping my gateway which gives me destination not reachable message. I also cannot ping my ESX4.0 from outside.

ping localhost and ping <ESX4.0 IP> from ESX service console are working properly. I really dont understand why I am not able to ping my gateway from ESX4.0 service console.

Thinking it might be a firewall issue, I have disabled firewall and iptables on ESX4.0. Still the problem persistes.

My all other VM's within ESX3.5 are working fine and i can get reply from the gateway too.

Any idea why am I getting this issue with ESX4.0????

It could be to the fact that running ESX 4.0 in a VM is not supported so my guess is it having problems with the virtual NIC -

Is there any doc/pdf that mentions about this unsupported feature??

Nothing official - I am just going from history in that running ESX inside a VM has never been officially supported even though you can - and since the HCL for vSphere will be much tighter than it is for VI-3

Did you change your portgroup hosting ESX 4.0 in promiscious mode ?

If not, that should be the issue.

Hey I enabled promiscuous mode...and it worked......And finally I can run ESX4.0 as a VM inside ESX3.5............
