    Hi All,

    Two windows 2012 hyper v host, both use NIC team LACP, and use Cisco switch

    VM in hyper A host, can ping hyper b host, can not ping vm in hyper b, also can ping other physical machine, can ping google,vm in hyper a can ping each other

    VM in hyper B host, can ping hyper A host, can not ping vm in hyper a, also can ping other physical machine.can ping google,vm in hyper b can ping each other

    hyper a host and hyper b host can ping each other

    all fw in host and guest disable. updated all nic network,

    all guest vm use different MAC address.

    who have same issue?

    I think it's switch cause this issue,but no idea how to correct it.

    Just a few questions that come to my mind that could be useful to find the solution.

    - Can you tracert the ip-address or hostnames of the machines?

    - Have you tried something like wireshark to track where you actually lose the package?

    - Are all machines visible in the server manager console? (either on a win8 or server 2012 machine)

    - Can the virtual machines be managed from a Hyper-V manager console?

    And sorry for asking, but what ip-addresses/subnet are you using for each machine?
    Are all addresses static, or do you have a dhcp-server in place?

    Hello

    usually it is a problem on your lag configuration.. just remove lacp use a normal load balanced team and see what happen.. however..

    you forgot to mention an important thing.. what kind of Vswitch on your hyper host are you using ?!
