How to add physical network card to vSphere Client?
Please answer!
Thanks

Are you wanting to add another NIC to your system or adding it specifically for a single VM to access?

Add it specifically for a single VM to use

Depending on the hardware you have you may be able to use VMDirectpath to pass through the NIC to the VM. VMDirectpath depends on AMD IOMMU or Intel VT-d to accomplish this.

In the vSphere client go to Configuration tab for the host and select Hardware > Advanced Configuration. If the option is available, click the Configure Passthrough link to enable the NIC for VMDirectpath.

Then edit the VM, add new hardware and select to add a PCI device.

If the Configure Passthrough option is not available, it may be that the option is not enabled or not available on your host.

I'm sorry,
Could you please tell me how to add a network adapter DRIVER while the Vmware host is installed

I don't beleive ESXi supports hot-add of NICs so you would have to shut the host down first.

I mean after vmware is installed

So I've reread the thread and it looks like you want to add a driver. Is there a driver package for the NIC from VMware or the hardware vendor? If so you would download the ZIP package and use esxcli software from the vCLI to update the host.

If it is a community driver in an oem file, you would simple need to add the file to /bootbank and /altbookbank and then edit boot.cfg in both locations to add your tgz file to end of the modules list.

I have added the driver but when I restart the server it hangs and now my computer won't start

What driver package did you use and what process did you follow to install it.
