Found the culprit!!! First of all, When installing Hyper-V and using an ISCSI LUNs, the MSiSCSI services is throwing DHCP discover packets when it start. After it finds the NIC that uses the iSCSI targets it uses that NIC and doesn't attempt to search for DHCP until the next reboot \ restart of the service. Apparently when installing SCVMM server and SCVMM ...

You should read documentation - hyperconverged setup at https://docs.microsoft.com/en-us/windows-server/hyperconverged/. Use all 4 machines to host S2D and VM's. Simple. It is a standard setup - basically a classic "RTFM and follow the wizards" scenario.

You can do S2D bare metal only. Storage Spaces (Direct) are unsupported inside the VMs (except Azure, but that’s another story to tell).

You want something reliable and with RDMA support. I’d stick with some Mellanox CX4lc NICs. This is what Microsoft uses to power Azure networking.

I believe what you are looking for is the Hyper-V Virtual Machine Connection tool. The tool can be installed easily on other servers and it uses the host to provide the connection to the guest, which gets around your no guest networking issue.

I would like to use the regular Ethernet adapter instead of vEthernet. Is the correct procedure to check all the items on Ethernet that are currently checked on vEthernet. Then, uncheck those options on vEthernet? No. What you're seeing is because your management OS (the Hyper-V host) is sharing the physical network card with the virtual switch. The network ...

Hyper-V NUMA spanning is what allows a VM's virtual NUMA nodes to span multiple physical nodes. This is bad for performance, when the guest OS is unaware of uneven memory latency. Leaving this off is better for performance, but it has operational complexities. As you discovered, if a guest cannot be placed in one node, it won't start. Consider this as if ...

It is PRETTY safe - note how it says in case of power failure? A UPS generally avoids power failures. If the server is connected to the UPS properly, it will see that battery power is getting used and start a shutdown in time (as per your configuration) so it never runs out of power (and yes, a shutdown, properly, is flushing those caches). Generally this is ...

A few months ago I set up two KVM hosts using CentOS 8.1.1911 with a Hyper-V VM as a nested guest and it all worked fine. A couple of months later, I set up a third KVM host with a near identical hardware and software configuration. The only difference was the motherboard, which had the same chipset, but was Gigabyte branded not ASUS branded as per the first ...

We were able to resolve the issue. When switching to Hyper-V virtualization we noticed that only half the CPUs were used. The reason for that was that only half of the memory slots were used on this system. After filling up the slots with more memory, all the issues were instantly gone. Both Hyper-V and process virtualization work as expected. Seems there is ...
