Windows 10: Windows 10 inside a VM hosted locally

Hello,


We have a need to have 2 Windows 10 installations on some of our company's laptops for use on a certain project. I have read https://download.microsoft.com/download/9/8/d/98d6a56c-4d79-40f4-8462-da3ecba2dc2c/licensing_windows_desktop_os_for_virtual_machines.pdf and if I am not mistaken this answers what I need to have:


Local Windows

Virtual Machines

An organization has a group of developers

who need to test an application across

multiple Windows images running in local

virtual machines on PCs running Windows

10 Pro.

The PC or the primary user of the PC needs

active Windows 10 Enterprise with Software

Assurance or Windows 10 Enterprise E3/E5

subscription, which permits running up to

four virtual machines concurrently.


What I do not understand is, do I need another license for the Windows 10 installation inside the VM or does Windows 10 Enterprise with SA covers licensing for the host OS + 4 Windows machines installed with the same product key inside the VM containers on the same local host.

Account failed logon 4625 on VM guest when clicking the entry of VM guest on failover cluster Manager on VM Host

Issue:

We found a multiple failed logon events on VM guest (evert ID 4625) with account (the account you logon on VM host) when we clicking the entry of VM guest on failover cluster manager console on VM host with Integration servers (Data Exchange) is enabled.



How to reproduce:

1. Check the “Data Exchange” is enabled on a VM guest (Enabled by default, right?)
2. Open Failover Cluster Manager Console on VM host.
3. Click the VM guest entry
4. Then you may found multiple failed logon events on that VM guest.

Reference:

Hyper-V Integration Services



Question:

1. Does the multiple failed logons are normal or necessary?
2. If the failed logons are normal and necessary to be happened and the “Data exchange” function is good to be enabled to gather data from VM guest, any recommendation for us to correct or avoid these failed logon?

Please advise.



Constrain:

We have no chance to use same account and password on VM hosts and VM guests (because all account are managed by password management) and the Audit Policy of Audit Credential Validation must be enabled.

 

Can you allow the host to use the VM network connection?

If you use a VM...

this is possible although not immediately obviously useful. My situation was one where the vm os was able to change settings on a wireless network adapter which allowed me to pick up the signal at a useable strength. The host could not do this. So I was in the weird situation where the vm os - backtrack - had internet but the host - osx 10.6 - did not. Annoying.

Easily corrected as follows:
1. connect the vm to the network, in my case this was wireless so wlan0
2. set up the vm so that is has a local network with the host, make sure the host can ping the vm. In my case this meant enabling eth0 in the vm
3. set up ip forward and iptables masquerade rules on the vm.
4. change the default route of the host to be the vm local ip
5. enjoy the vm network via the host


now I imagine some readers will want more detail on ip forward and masquerade with iptables but there are a lot of tutorials out there for this stuff. It depends on the vm os but if you are using linux then

ip forward with:
$ echo 1 > /proc/sys/net/ipv4/ip_forward

iptables rules something like this
iptables -t nat -A POSTROUTING -s $PRIVATE -o eth0 -j MASQUERADE

{clearly $PRIVATE is your private subnet, set the rules up to run at ifup}

Can I share a network connection from a VM to the host OS?

hmm, i will assumer no responces = no, i cannot share it... lucky me, i finally got it to work in 7 with steps pretty close... Program Files > Pantech is where you will need to point windows to inorder to the card running in 7... though it would be nice to be able to share hardware and network connections from a VM to the host PC...
