We are experiencing intermittent connectivity on our vms. When a user complains about a specific virtual machine I ping the machine and it will have latency up to 3983ms but when I ping the blade that the machine resides on its connectivity seems unaffected in the ping status. I am not for sure if this is a host issue or if something else is going on. Not only does remote desktop sessions fail when it does work the machine has extreme lag to the point of unavailability.
.
We currently have 28 hosts in our main cluster. I think VMWARE's recommended limit is 33 hosts which we are in that range. I don't know where to begin troubleshooting this issue considering the physical infrastructure seems to be working properly.
Does anyone have any suggestions that would be a sound process in diagnosing this problem?
Are there any network diagnostic tools for virtual environments to assist in troubleshooting?
