ESXi VM NTP Server

ntptimevirtualization

We need to setup an internal NTP server.
Because this server will pretty much ONLY be a time server I was thinking of just creating a VM for it.
However, Googling around it appears that there there might be serious clock drifting issues with VM servers.
So, is running our NTP server in a VM a completely dumb idea?

Thanks,
John

Time can be a problem inside VMs but by the same token if done correctly can be as accurate as a physical machine. It may seem odd but I'm a huge fan of using my switches (always Cisco in my world) as my NTP sources - not only are they easy to setup as such but it they have the handy benefit of being your DG too usually - see if your switches can do this too.
