Hyper-V Issues

[deanbossert4 (Dean Bossert)]

hello,

I Windows Server 2012 installed on a machine and im trying to test something before i buy a 3000 dollar server.

i have hyper-v installed on the machine with 2 windows 7 86x vm’s running on it ip’s are 10.0.70.22 & 10.0.70.31

the servers IP is 10.0.70.18

and my actual desktop is 10.0.70.15

the problem i am having is as follows.

i can ping the server(.18) from my desktop(.15) but i cant ping the VM(.22)

i can ping the desktop(.15) from the server(.18) but not the VM(.22)

HOWEVER

from the VM(.22) i can ping the server(.18) and my desktop(.15)

the point of these VMs is to have users log onto them using remote desktop to preform functions… please advise.

i think it is a windows firewall issue but i am unsure

Well you certainly can use them in such a way for all devices to connect to each other. It very likely is a windows firewall issue.

Try a traceroute how far down the chain does that get?

Wireshark where are the packets getting dropped?

Are these computers joined to a domain?

If they are part of a work group then make sure you make that network a company network. (You know how Windows first connects to a network and it asks you if its a home/business/public network? Don’t choose public network.

It probably won’t be that simple but best check the easy stuff first, right?

Is the Virtual Switch you created configured as External?

If so, disable all firewalls and try.

[Gary-D-Williams]

Have you tried turning the firewall off on the VM’s and seeing if that works?

Is RDP enabled on the VM’s? By default it’s disabled.

What kind of switch did you setup? (External, Internal, Private)
I assume they are WORKGROUPs and not in a domain?
Just to test, can you either turn the firewall off and/or allow ICMP (on the VMs)?

Have you looked into a terminal server?

[benisj]

if you suspect a firewall issue, you should start disabling the entire firewall one device at a time and see if eventually you get the connections you expect, then troubleshoot the firewall that magically unlocked everything.

How many licenses are you using?

If hyper-v is the platform, a single standard license will allow you to install the hyper-v role, then two VMs as guests. However, you reference your desktop IP and pinging from/to that desktop. For a single license, the host must be running ONLY the hyper-v service. That could be a source of issues.

If, however, your guest VMs were installed with a different license, then that should not be the issue.

In that case, have you configured the virtual network adapters?

Configure Networking

[deanbossert4 (Dean Bossert)]

all of these machines are joined to he same domain. they are all selected to be company/work networks.

the virtual switch in hyper-v is an external

the only thing i see that is weird is this: the windows server is using the the virtual switch for an adapter…

[mattscan (Matthew5502)]

Ah, yes. If you only have one nic, hyper-v will abscond with it. It can cause issues. If you have dual nics, configure the other one.

Given your configuration I’d look at the firewall in the VM guest. Can the VM Guest connect out to your network and also the world?
