Hyper-V Network Virtualization

0
0

Hi,

Good Day!

Hyper-V Network Virtualization is bit confusing and not much documentation available on practical examples.

Appreciate your time for clarifying some of our doubts:

CustomerA has two VMs (RDID1) and CustomerB  (RDID2) has three VMs running on the "same" Hyper-V Host. There is only one provider address (192.168.2.2). This PA is used for all the VMs (two + three). 

We have implemented an open source software router as a VM on the same host. We would like RDID1 VMs and RDID2 VMs to use one gateway IP address (VM Router). Is it possible or we need to have one router VM for each VM Network? Our primary goal is to allow VMs to access Internet via this router. So we don't want to implement two routers for two VM Networks.

We also would like to know the gateway IP address to be used by the VMs. For example, we assign 10.0.0.99 IP Address to VM Router. Since the PA address is 192.168.2.2, we thought of using 192.168.2.1 as the default gateway address for VMs and assign the same IP to VM Router also. Please clarify. 

Thank You,

Aurther L

Gen 2 Server 2012 VMs fail to start after December Windows Updates

0
0

I've been able to reproduce this on two separate hosts (both Win 8.1 Pro) running Gen 2 Windows Server 2012 VMs. I believe it is after the December 2012 round of updates (and I'm trying to confirm which specific one), the VMs fail to boot, indicating that applying a patch failed and it is reverting the changes -- it enters a reboot loop which I'm unable to get out of.

Has anyone else experienced this with Gen 2 Server 2012 VMs?

VMs have no network connectivity after reboot

0
0

Hello,

We've recently had a problem appear across our Hyper-V 2008 R2 and 2012 clusters. When a virtual machine is rebooted, some of its virtual network cards will have no network connection. The VMs run 2008 R2 and 2012, both of which are affected.

Some VMs have 4 virtual NICs and different ones will lose connection randomly, it can take 4 reboots before all of them are working. The problem happens as soon as the VM comes up after a reboot, the network shows as connected in Windows, yet no traffic will pass through it. Running an ipconfig on the affected VM will show 2 IP addresses for each NIC with no connection - the normal static address and an autoconfiguration 169 address.

The hosts and VMs are all up-to-date with the latest patches, integration services have been updated on all the VMs and there are no errors showing in the event logs. I've tried reinstalling the virtual NICs, created a new virtual switch, disabling offloading and disabling VMQ but nothing has helped. Once all the virtual NICs are connected, they don't have any more problems until the next reboot.

I'm really stuck with this one now.  Any advice would be appreciated.

Connect to Hyper-V guest via RDP, Wake on RDP

Hi all,

i am using Windows Server 2012 and integrated Hyper-V to virtualize some old machines and a few new ones to replace physical PCs.

Some of the machines are only needed a few times. I am able to connect to the VMs via RDP just by IP as if you would connect to a physical machine - works. But how can I wake up the machines via RDP? May I adress the machine over the server, which wakes up the machine and redirects me to it?

Thanks,

Hans

Why a max of 50 snapshots with Hyper-V?

0
0
I realize the more snapshots Hyper-V has the more inefficient the machine gets - by the time you get to 50 it must be crawling. I was wondering, however, why is the limit 50? Is this an arbitrary number for the sake of efficiency, or is the limit due to something else? I have no intentions of getting up to 50 snapshots, but I was wondering if there was a solid reason for this limit instead of "I guess it has to do with efficiency." I could not find any documentation that said why the limit was 50.

0.0.0.0 IP Address Conflicts on the network, VMs lose network after reboot

0

We are having a strange issue happen on our network which appears to be affecting most hosts and VMs which is a combination of a Windows 2012 Hyper-V Cluster and Standalone Windows 2008 R2 Hyper-V Hosts.

Prior to implementing the Windows 2012 Hyper-V Cluster we did not have the issue. That said, previously we did not use NIC Teaming either.

The problem appears during the gratuitous ARP request during a reboot for any Physical server or VM that are running Windows 2008 R2 & 2012. The Host or VM gets a conflict with a 0.0.0.0 address and then assigns itself a 169.254.X.X IP address. The conflict arises from the uplink Trunk port MAC address from a Cisco Switch. The conflict MAC address randomly changes and can be from any of uplink Trunk MACs from all access switches in the network. I can not reproduce the issue on a Windows 2003 box but this likely because Microsoft changed how gratuitous ARP works since Windows 2008.

We are using NIC teaming with switches that were created at the Host level not in SCVMM 2012 SP1. We are also using standard VLANs. There is a MGMT team which uses a separate pair NICs. The NICs on each team are split over 2 Cisco switches with all adapters active for load balancing and redundancy.

The cluster and livemigration networks are vEthernet Adapters that use the Hyper-V NIC team which is the same team the vSwitch is connected to.

The bandwidth allocation is done by weight and not by percentage.

Portfast is enabled for all end devices.

Any help would be great!

HyperV with VLANID does not work!

0

Hello, 

I created a nic teaming with 3 network cards and a virtual switch. 

My need is to create the following scenario: 

- Nic Teaming with 3 network cards 
  - VEthernet (Live migratory-on) - 1 VLANID 
  - VEthernet (ClusterHB) - VLANID 2 
  - VEthernet (Management \ Backup) - VLANID3 

I have two switches cascaded in (LinkAgredation / Trun-k). 

My server is connected as follows: NIC1: SW1, NIC2: SW2, CIN3: SW1 

I asked for support networks configure the switch ports which I will use for my NICs in Trunk. 

Here we go: 

- I created the Nic Teaming in Independent mode - HyperV-Port 
  - Created vEthernet (Live migratory-on) - 1 VLANID 
  - Created vEthernet (ClusterHB) - VLANID 2 
  - Created vEthernet (Management \ Backup) - VLANID3 

My main network I'm connected is in VLANID 3 (172.16.16.50) and try to ping the vEthernet (Managment \ B-ackup) - VLANID3 that has the IP: 172.16.16.60 does not work. 

I removed the NIC Teaming and put the IP: 172.16.16.60 on each (NIC1, NIC2, CIN3) to verify if there was any problem in the SW configuration, but the ping worked normally. 

The problem only occurs after creating the nic teaming. 

PS1: I put the IP: 172.16.16.60 directly in the Nic Teaming driver, I type changes Nic Teaming for static and not funciounou too. 

PS2: I created a second nic teaming, as your blog and assigns putting VLANID3 and neither worked an IP. 

What am I doing wrong? 

Thank you....

Hyper-V Events-- 10170 and 16010

Hi, 

On a windows 2012 when I take a backup, I see error in windows event viewer, though my backup job is successful.

"Requester reported unsuccessful backup for the virtual machine '<computerName>'. (Virtual machine ID)"

The exact snippet of the event message is as below. 

Error 11/28/2013 8:39:42 PM Microsoft-Windows-Hyper-V-VMMS 16010 None The operation failed. Warning 11/28/2013 8:39:42 PM Microsoft-Windows-Hyper-V-VMMS 10170 None Requester reported unsuccessful backup for the virtual machine 'ABC-Eng01'. (Virtual machine ID XXXXXXXX-YYYY-DDDD-DDDD-BBBBBBBBBBBB)

What does this event message mean?

Does it mean that my backups aren't successful? Do I need to take care of something in my setup so as not to see this error events?

Is there any known windows issues already logged around this? I dont find any KB article for the same.

Thanks,

Santosh

Hi

We have configured Hyper V clustering with Windows 2012 R2 DC. All the disks are configured as CSV, later installed guest OS and applications and everything is working fine as of now. Now most of teh CSV are showing the information Chkdsk scan needed. We are looking for a solution to correct this / run Chkdsk on CSVs and if required how frequently do we need to run chkdsk on CSVs

Thanks in advance

Dear sir,

Problem : Hyper-V failed to enable replication for virtual machine 'xxx' : Cannot create a file when that file already exists. (0x800700B7). Virtual machine ID 27bxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx

Replication scenario : I am getting this error while i am enabling the replication again as it was disturbed so i need to re-enable it. But getting upper error.

Replication for other two VMs are running. But other replication of two VMs are stopped so i have removed the replication and deleted the VM folder from replica. still it is showing as above and not enabling the replication.

Please help.

HyperV 2012 R2 Cluster across two Datacentres

0
0

I need to design and implement a Hyper V 2012 R2 cluster.

We have two Datacentres (DC). Both Datacentres are connected with 20 GB network connectivity.

Each DC has its own SANs and SAN replication is enabled for some LUNs. Within a month SAN will get its own 10 GB connectivity which will allow servers in one DC to use SAN in the Second DC.

Should I create one cluster spanning across two DCs? Or Create one cluster in each site?

Are there any best practices for designing Hyper-V cluster across Datacentres?


Kind Regards Tim (Canberra)

Microsoft VDI Error

0
0

Hi,

I have a Microsoft VDI LAB setup with Windows 2012 Core servers. Recently I started facing some issues in the VDI setup.

I am getting authentication error (Error 1) when I launch the Virtual Machines. And also I am not able to create the new Virtual Machine pool using gold image  (Error 2 - Getting the network error).

Error 1:

An authentication error has occured.
The Local Security Authority cannot be contacted
remote computer:
This could be due to an expired password.
Please update your password if it has expired.

Error 2:

Could not identify the state of the virtual desktop. Ensure the RD virtualization host serveris avaliable on the network and that the virtual desktop gold image test1 is shut down.

So far i have taken the below steps to troubleshoot,

1. Created the new test gold image.

2. Rebooted the Virtulization Hosts.

3. Rebooted the VMM, RD gateway and Connection broker servers.

4. AD diagnostic has been done and did not find any errors.

Please let us know if any one gone through the same error and any work around.
