I'm trying to get vlans set up and I'm having an issue

I am using PFSense Firewall Virtualized in hyper-v

I'm trying to get vlans set up and I'm having an issue
Set up is as follows:
1 PC Running Server 2012 with Hyper-V Enabled with 2 Nic Ports
3 VMs
1 CiscoSG300 10 port small business switch
1 Laptop for testing Ports on Switch

PFSense in Hyper-v VM with 2 Virtual NICs
1 nic is attached to 1 physical nic acting as WAN
2nd nic is attached to 2nd physical port acting as LAN


PFSense is set up with 2 vNICs 1 is attached to a vswitch that is attached to 1 physical NIC Actinga s WAN PORT
2nd vNIC is attached to 2nd Hyper V Switch that all the Other VMs are attached to that is also attached to the 2nd Physical NIC Acting as LAN PORT
LAN Port is connected to a Cisco Small Business 10 port Switch


Other VMs
1 With AD,DNS,DHCP(With IP Address Scopes set up for Vlans)
1 For File Server


PFsense is setup as follows:

LAN          10.100.1.1/24
VLAN 2     10.100.2.1/24
VLAN 25   10.100.25.1/24
VLAN 100 10.100.100.1/24
VLAN 150 10.100.150.1/24


VLANS are set up in PFSense and Configured correctly

Ran this command on the Hyper-V Server to set the vNIC for LAN in the PFSENSE VM to Trunk mode and allow the VLAN IDs

Set-VMNetworkAdapterVlan -VMName PFSENSE -Trunk -VMNetworkAdapterName LAN -AllowedVlanidList 1-150 -NativeVlanID 1

VMName  VMNetworkAdapterName Mode     VlanList
------        --------------------           ----     --------
PFSENSE    LAN                              Trunk    1,1-150
PFSENSE    WAN                             Untagged

My Other VMs are set up with the vlan tag turned on and they are working an will pull an ip address and can talk to devices on other Vlans

My issue is the Physical Cicso Switch doesn't seem to be passing traffic

The Switch is Configured as Follows:

10 port switch
Switch IP 10.100.2.200

Port        Mode         VLANID
1            Access         2    Untagged
2            Access         25  Untagged
3            Access         25  Untagged
4            Access        150 Untagged
5            Access        150 Untagged
6            Access        100 Untagged
7            Access        100 Untagged
8            Access        100 Untagged
9            Access         2    Untagged
10          Trunk         1,2,25,100,150 Tagged

Port 10 is connected to the Lan port on the Physical Server witch is attached to the V-Switch that PFsense is attached to but I am unable to get anything to pass to this switch in pfsense I cant even ping the switch 10.100.2.200

Any suggestions on what I have wrong here?

Hello everyone

I have a server HP Proliant DL180 that has server 2012R2 and two virtual machines one of those virtual machine needs to be restarted every one or two days CPU reaches 99% I checked it and found that system idle process is consuming all the CPU resources so I need to restart it, after restart the virtual machine works properly until the system idle process reaches 99% I read an article that I need to reinstall integration services but it seems that we can't uninstall and reinstall it an idea or solution or something that I can do to find what causing this server to consume all the CPU resources

I am trying to set up a computer to handle multiple VM's, each running SpinRite on a single drive attached to the mother board.

I have that part all working, in the sense that SpinRite starts up and detects the physical disk I've passed through to it from Server 2008 R2. The issue is that SpinRite believes the VM is reporting the disks size incorrectly so it won't run. Do VM's do things to the reporting of passed through disks that could account for this?

Hi guys.

We have an USB key which contains some license file. The USB key does not behave as "normal disk".
is there a way that we could connect this device on hyperv host and from there "push" the connection to VM?

With best regards

I'm running Windows Server 2012 R2 and the guests are on iSCSI targets. Using the Dell AutoSnapshot Manager from the host, AVHDX files are created while the tool coordinates quiesceing the operating system to make an application consistent snapshot on the SAN.  This works great, but sometimes an ADHVX file gets orphaned and are not merged afterward, and I want to know about it immediately.  Is this activity logged somewhere?  I can't seem to find anything.

Did anyone else have the same problem? What's the workaround to this issue? I can't afford complete reinstalling here, since I work remotely.

Trying to access Hyper-V running on Server 2012 R2 from Windows 10 LTSB 2016 and I only get an error:

The Hyper-V Management Tools could not access an expected WMI class on computer....

Same server accessed from Windows 8.1 H-V Management Tools is working fine.

Anybody any idea?

According to this it should be no issue

I have a hyper-v guest that is displaying an odd behavior.  Both Host and Guest are running 2012 R2 server core.   The guest is a DC/DNS/DHCP/Print server.  Printing is very low volume.  Both host and guest are current on updates, including integration services.  

The guest is configured with Dynamic Memory using the following settings:

Startup: 1024
Minimum: 512
Maximum: 6144
Buffer: 20%

The issue is that the Memory Demand reported by the host doesn't reflect the memory current in use on the guest. Here is an example:
Guest Memory Available: 1.6 GB
Guest Memory Usage:1.6GB (100%)
Host Assigned Memory: 1682MB (1.6GB)
Host Memory Demand: 1446MB (1.4GB)

You will note that I have 6GB available to the the guest, which its not using, and a 20% buffer that its not getting.  It appears to me that the Host is behaving correctly because it thinks the guest is at 85 percent utilization (it ticked up to 1.7GB Assigned shortly after this reading).  What I can't figure out is why the host thinks this guest is using less than it is.  What is also interesting is that it seems to scale with increased memory.

Any ideas?

I love the new Task Manager in Server 2012 and Windows 8. However in Hyper-V 2012 Standalone it does not show disk performance/usage. I've also noticed that the Disk graphs don't show up in Sever 2012 either. Does anyone know if it's possible to get them to show up? I'm using VMM 2012 right now and that reports on disk activity but I'd like a more active live feed of disk usage on the system. The "open resource monitor" option is in the task manager on Hyper-V standalone but doesn't work.

Hello,

I'm new to the clustering and I had a stand alone server with 8 Virtuals running on it.  I create a cluster and joined this server to the cluster. I first tried to figure out how to move the vmachines in to cluster and gave up.  So I just deleted them in Hyper-V manager and copied the vhdx to the LUN on my cluster and went to Roles and clicked New Virtual Machine and selected the hard drive and all seem to work as excepted. Then I noticed the Machine showed back up in Hyper-V manager is that normal? So then I tried this same approach on a second server it seemed to work but the Vmachine does not get added to the Roles only the first machine is listed in the Roles on the Cluster. It does show in the Hyper-V manager.  Am I missing something? 

What I have it a two node cluster both running server 2012  with a P2000 G3 storage.

Thanks 

Randy

Hi!

We have 4 Teamed NICS in our Windows 2012 Hyper-V Servers. Is it better to remove one NIC from teaming and fix it for VM Migration among Servers?

Secondly, is it better to use a different IP Range for migration network? Does it increase the speed of copying process?

Thanks.

I was doing updates on my 2012R2 Hyper-V VM and power dropped. When I booted my host PC back up the VM would start and say Hyper-V Updating your system (x%) and get stuck at 5%. I can't get past this and I have no snapshots/backups of the VM. Is there anyway to recover this VM?

Hello, I just upgraded my machine to Windows 10 and now my Hyper-V Manager cannot connect to and manage our Server 2012R2 Hyper-V Hosts. I get the following error.

"An error occurred while attempting to connect to server xxxxx. Check that the Virtual Machine Management service is running and that you are authorized to connect to the server."

I've read in multiple places that Hyper-V Manager in Windows 10 and Server 10 will support managing Server 2012 and 2012R2 hosts. I'm not sure why it's not working though.

Any help would be appreciated.

I have a Zotac CI323 mini PC. I planning on running Hyper-V Server 2016 with a pfSense guest for routing and firewalling.

The PC has two gigabit interfaces - both are Realtek 8868G chips.

I intend on using one for the LAN connection, and the other for WAN.

My problem is that when I create a VM Switch on the LAN interface ("Ethernet"), all traffic is blocked. My host and guests cannot communicate on that interface. Analysis with Wireshark shows, for example with pings, that an ARP is sent out from the host, and the remote computer sends back an ARP reply, but presumably that reply never gets back to the host once it reaches the interface. Removing the VM Switch restores connectivity.

Meanwhile, my intended WAN interface ("Ethernet 2") works fine with a VM Switch enabled - traffic passes without any problems, from the host and from the guest. Despite being the same chipset.

So far, I've tried the following steps:

Disable firewall

Reset IP stack

Configure static/DHCP IP on interface

Install latest Realtek drivers (v10.010.0714.2016)

Install latest Windows updates.

Verified switch VLAN port settings.

Checking NIC settings using NVSPBind.

I have 2 windows 2012 servers in a cluster, and the Quorum Disk (1GB) is about to run out of space.  I read that when it does used up all the space, the cluster service will stop working.  Currently all the spaces in the server are assigned to other virtual disks, so there is no room for me to create a new VD and move the Quorum to.

Can quorum be moved to the same space as the Cluster Shared Volume?  Or is there anyway to safely trim the size of the quorum to reduce it's size?  Thank you.

From my hyper-v host (windows 10), I was running anyconnect vpn.

The vpn was operational after I started a hyper-v client (linux) when following a docker for windows tutorial.

The vpn stopped working after I started a hyper-v 'external network switch', as per this link in the docker website: https://docs.docker.com/machine/drivers/hyper-v/

I doubt my IT department can help me restore the anyconnect vpn.

I'm looking for a starting point on how to isolate the problem and restore the vpn, myself.

My skill level: long time linux based software developer, with moderate understanding of IP networking.  No experience with windows admin, or networking.

Can any reader direct me, please?

Thanks

We have a Hyper-V host in a branch office to replace our existing VMWare Host.  We have created a Domain Controller Guest on the Hyper-V host and it is funtioning fine (it is talking to the DC on VMWare).  When we tried to enable the DHCP server on the Hyper-V DC we do not get any lease requests from laptops or desktops outside of the Hyper-V host.  We buit a Guest Server on the Hyper-V host and set it to DHCP and it works, grabs a lease.

The Hyper-V host is sitting on a Cisco UCS server, we are checking those setting also.

DHCP Upguard is not enabled on the Hyper-V Guest NIC

Are we missing anything in the Hyper-V host that will block DHCP requests?

Hello all,

I've created a cluster that consists of two nodes. We've created some VMs and everything was great. By Mistake, one of my colleague destroyed the cluster. We did not have a cluster for awhile since the hyper-v servers were not production yet. Now we're planning to create the cluster again.

The question is would the cluster manager overwrite the contents of the shared disk?

BTW, number of VMs were created on the shared disk after the cluster was destroyed.

Regards.

Boa tarde!

Na nossa organização temos dois dominios: dominio-A e dominio-B. Para acabar com os dois dominios e criar um unico dominio de gestão, pretendo criar um novo dominio-C. 

Gostava de saber quais as implicações que tem nas aplicações existentes, Emails, etc.

Pretendo seguir os seguintes passos:

-criar um novo domain controller com um novo dominio dominio-C

-para os novos pcs e servidores que se criem, adicionar ao novo dominio-C

-os pcs antigos ir mudando gradualmente para o novo dominio-C.


O nome do dominio que quero criar vai ter o mesmo nome que tem actualmente o do email xxx@dominio-C.

O facto de criar um dominio com o mesmo nome que é usado nos emails traz algum problema para os emails? Não sei se expliquei bem o que pretendo...
