2024-02-21_13-21-15.jpgHello, We have 2 Hyper-V cluster's both which are experincing network connectivity issues. These are hosted on-premise, Hosts are domain joined, one cluster is 2 node and the other is 3 node. I noticed recently that most of the cluster networks are being classified as public profile which seems odd to me. These are built out with network segregation, vlans, dedicated switching, etc. The VM/MGMT network is domain which is what I would expect however the others such as live migration and cluster are public, ISCSI as well. So, should these be private? Any feedbck would be appreciated.

    Hey,

    I've never changed network profile for iSCSI and Live Migration networks. Public profiles don' have certain services (like file sharing) enabled. It shouldn't have any influence on your issues. https://answers.microsoft.com/en-us/windows/forum/all/should-i-choose-a-public-or-private-network/1544a14f-d7b2-49d4-a26c-26d3b38c5819

    What kind of issues are you facing? If you have antivirus software installed, you should check that it doesn't block traffic. You might need to add exclusions to AV software. Might be helpful: https://www.starwindsoftware.com/blog/configure-live-migration-in-hyper-v-clusters

    Hi Zwart,

    Hope you're doing well.

    1. Double-check the network settings on each node of the Hyper-V cluster. Ensure that the NICs associated with VM management, cluster, live migration, and iSCSI have the correct VLAN settings and are associated with the proper virtual switches.
    2. Ensure that the Windows Firewall rules are configured appropriately for each network profile. For domain and private networks, necessary rules for cluster communication, Live Migration, and other cluster functions should be allowed.
    3. Some 3rd-party anti-virus may influence. You can try to disable it and then check whether the issue exists.

    Best Regards,

    Ian Xue
