Product Activation - Says "Not Available"

Hello all,

I apologize for asking about a Production Activation issue but I just want to be clear on something. I just formatted my PC today and re-installed Windows 8 Pro and activated just fine.

I enabled Hyper-V and installed a new Virtual Machine and pointed it to the same installation disk and provided the same Product Key. I am concerned because I never got an error or wanring about it validating or not. 

When you right click on My Computer and look at the default page that has your system specs, at the bottom where the Windows activation section is it simply says: Product ID: Not Available.

Should I be worried?

No external network access from guest VM, on Windows 8.1 host

This is driving me crazy and I've spent a little too long of a vacation trying to figure thus out. But since this vacation was a chance for me to make some progress on a non-work project - well, it's really bugging me (and is a blocker I've had for two days so far)! Any help would be appreciated.

I am running HyperV on a Windows 8.1 host. I need to create a guest that has internet access. Just to remove any questions as to whether my hardware and OS installation support this, I had this working perfectly last week on the exact same machine. I simply added an external network through the HyperV Virtual Switch Manager, added that under Settings -> Network for the VM in question and everything just worked immediately. The guest obtained an IP address just fine and all was rosy.

So, then I come on vacation and set up a VM. I'm on a different physical network but everything seems the same from the host perspective - I just connected to the wireless network and the host itself works just fine.

However, no matter what I try I can't get the guest VM to obtain an IP address. I've done the same configuration with the external virtual switch, bound (in Settings -> Network) to the VM and so on. The VM sees the virtual NIC card just fine - but always fails to obtain an IP address (can't reach the DHCP server, I believe).

The only thing that has changed - as far as I know - is the network environment. The new environment immediately and easily supported me getting the host hooked up (it got an IP address itself) and provides access to the Internet.

By the way, I did see some recommendations to create an INTERNAL virtual switch and bridge with the wifi connection. I don't know why that would be preferred over the more direct use of an external virtual switch - but, regardless, that approach failed too (same issue - no response from DHCP server).

Any ideas on what might be going on here?

Thanks in advance.

Hi,

We have 2 windows server 2012 Datacenter member of windows cluster, servers are running hyper-v. the 2 nodes hang once we try to access CSV volume (c:\clusterstorage\volume1) when i tried to do live migration from node1 for virtual servers and move it to node2 it fails. also when i restart node1 the server keep on "Please wait for the System Event Notification Service"

cluster events:

1- Cluster resource 'Virtual Machine' (resource type 'Virtual Machine', DLL 'vmclusres.dll') did not respond to a request in a timely fashion. Cluster health detection will attempt to automatically recover by terminating the Resource Hosting Subsystem (RHS) process running this resource. This may affect other resources hosted in the same RHS process. The resources will then be restarted.

The suspect resource 'Virtual Machine' will be marked to run in an isolated RHS process to avoid impacting multiple resources in the event that this resource failure occurs again. Please ensure services, applications, or underlying infrastructure (such as storage or networking) associated with the suspect resource is functioning properly.

2- The cluster Resource Hosting Subsystem (RHS) stopped unexpectedly. An attempt will be made to restart it. This is usually associated with recovery of a crashed or deadlocked resource.  Please determine which resource and resource DLL is causing the issue and verify it is functioning properly

3- Cluster resource 'Virtual Machine Configuration' of type 'Virtual Machine Configuration' in clustered role  failed.

Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it.  Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.

4- Cluster Shared Volume 'Volume1' ('Cluster Disk 2') is no longer accessible from this cluster node because of error 'ERROR_TIMEOUT(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.

5- Cluster Shared Volume 'Volume1' ('Cluster Disk 2') is no longer available on this node because of 'STATUS_IO_TIMEOUT(c00000b5)'. All I/O will temporarily be queued until a path to the volume is reestablished.

Unknown devices on Windows 2003 Virtual Machines

We have recently setup a Windows Server 2012 R2 environment, Hyper-V and Clustering.

Our existing environment is Windows server 2008 R2 / Hyper-V and Clustering.

We are experimenting with migrating VM’s from the old cluster to the new cluster, either using the cluster migration wizard or simply exporting VM’s / re importing VM’s

We are experiencing issues with Windows Server 2003 R2 virtual machines, we always end up with 2 unknown device drivers in the device manager, both are stating they are on the Hyper-V Virtual Machine bus, we have installed  the integration services on the VM’s, we have even on the existing ones removed any mention of the Integration servers from the registry and completing a fresh install but they still show up as unknown.  The strange thing is the device status is working properly, the VM functions correctly but I’m not happy going forward into production with unknown device drivers.

Windows 2008 guests are fine it’s only Windows 2003 guests, we still need to run a number of these legacy servers so upgrading the VM’s not an option.

Has anyone else come across the issue / fixed this issue?

Any advice?

Hi,

I am running a custom Linux VM on Windows Server 2008 R2 Hyper-V.

I need to get the version/hostname of Hyper-V from the running custom Linux guest. How can I do that?

I am having Integration Service 3.4 installed. Is there any option I can configure using Integration Services code?

What is the Linux kernel version in which Integrations Services code is ported? I hope 2.6.32. Is this correct?

Any help is appreciated.

Hi all,

I am running a custom Linux VM on Hyper-V 2012. Do we have a virtual machine packaging mechanism in Hyper-V 2012 Server, similar to OVF in ESXi?

I tried MSVMC tool. But looks like it only works for Windows guests.

Do we have any other option for getting a VM package in Hyper-V ?

Thanks in advance,

I cannot import my Vm's on a new Server 2012 R2 box.  The old server ran Server 2008 core.  I get the error "Hyper V did not find virtual machines to import."  I have trying exporting and importing, also have tried turning off the hyper v management service after shutting down all the VM's and copying the virtual hard drive to the new server.  Nothing worked.  Is there an incompatibility between these versions?

Adding routes to Hyper-V

December 18, 2013, 9:12 am

Hi,

I have 2 Hyper-V 2012 R2 servers. They have 4 nics each, which is fine.

Now they are in their own vlan so my host has told me I need to add routes to each server.

So I have:

A (physical server)
B (physical server)

A1, A2, A3 and so forth (VMs on A)
B1, B2, B3 and so forth (VMs on B)

A and B can ping each other, but B cannot ping A1 etc, despite being in the same subnet in terms of ip config settings (same switch etc).

The host has said this:

You need to setup static routes on both servers, if both servers are in the same
subnet. You need to do that, because our switches are configured with vlans for
security issues. 

route add -host xxx.xxx.xxx.xxx (=IP of the server you want to reach) gw
xxx.xxx.xxx.xxx (gateway of the subnet) eth0

Note that I use Hyper-V server so I can't add things like RRAS role to the parent OS.

The servers A1, A2, A3 etc do not have gateway IPs as they are not on public IPs, so I am not sure how to add route entries as I keep getting paremeter incorrect, eg:

route add 10.0.0.0 mask 255.0.0.0 192.168.0.1

Hi,

We would like to create a master virtual hard disk and use the same for all other VM's. Can we do that ?

my requirements :

1) create 10 VM's

2) first create a master virtual hard disk with win OS and use the same to create the 10 VM's.

3) After creating the VM's change the HDD size.

              -- if i have created master virtual disk with 500GB , and use the same for creating a virtual machine. can we change the HDD size to 1TB ?

After creating the VM's ,i will change the system names and activate the windows accordingly.

Will there be any implications ,if we can/will do like this.

Thanks.

Hi,

I have the Hyper V 2012 R2 standalone edition running with two Windows 2012 VM running on one physical machine.   The hyper-v is not joined to the domain but both the VMs are.   I have no problem with the VMs.   I do not seems to be able to login via the administrator (via keyboard attached to the machine) to the hyper-v via the password that I setup earlier during the installation.

What is the best way to reset the local administrator password?  Any help would be appreciated. Thanks.

Can I install a Server 2012 R2 VM on a Server 2012 Hyper-V Host?

Hi all,

I'm just wondering if there are any implications of installing a Server 2012 R2 VM on a Server 2012 Hyper-V Host?

I currently have 3 VM's on this host. 2 are Server 2012 and the other is Server 2012 R2. The biggest problem I'm having is when I run my backup (Altaro). The Server 2012 VM's completes the backup without a hitch, when it gets to the Server 2012 R2 VM it basically freezes the backup until the backup is complete. Altaro support have recommended untickingthe 'Volume Snapshot' Backup option from Integrated Services, but this seems to pause the VM for a few seconds before it proceeds with the backup. This is an RDS Server, so all the clients gets disconnected at this stage and they have to log back in.

Any help on this would be much appreciated.

Hyper-V over SMB 3.0 poor performance on 1GB NIC's without RDMA

December 19, 2013, 3:03 am
$

This is a bit of a repost as the last time I tried to troubleshoot this my question got hijacked by people spamming alternative solutions (starwind) 

For my own reasons I am currently evaluating Hyper-V over SMB with a view to designing our new production cluster based on this technology.  Given our budget and resources a SoFS makes perfect sense.

The problem I have is that in all my testing, as soon as I host a VM's files on a SMB 3.0 server (SoFS or standalone) I am not getting the performance I should over the network.  

My testing so far:

  • 4 different decent spec machines with 4-8gb ram, dual/quad core cpu's, 
  • Test machines are mostly Server 2012 R2 with one Windows 8.1 hyper-v host thrown in for extra measure.
  • Storage is a variety of HD and SSD and are easily capable of handling >100MB/s of traffic and 5k+ IOPS
  • Have tested storage configurations as standalone, storage spaces (mirrored, spanned and with tiering)
  • All storage is performing as expected in each configuration.
  • Multiple 1GB NIC's from broadcom, intel and atheros.  The broadcoms are server grade dual port adapters.
  • Switching has been a combination of HP E5400zl, HP 2810 and even direct connect with crossover cables.
  • Have tried stand alone NIC's, teamed NIC's and even storage through hyper-v extensible switch.
  • File copies between machines will easily max out 1GB in any direction.
  • VM's hosted locally show internal benchmark performance in line with roughly 90% of underlying storage performance.
  • Tested with dynamic and fixed vhdx's
  • NIC's have been used in combinations of RSS and TCP offload enabled/disabled.

Whenever I host VM files on a different server from where it is running, I observe the following:

  • Write speeds within the VM to any attached vhd's are severely effected and run at around 30-50% of 1GB
  • Read Speeds are not as badly effected but just about manager to hit 70% of 1GB
  • Random IOPS are not noticeably affected.
  • Running multiple tests at the same time over the same 1GB links results in the same total through put.
  • The same results are observed no matter which machine hosts the vm or the vhdx files. 
  • Any host involved in a test will show a healthy amount of cpu time allocated to hardware interupts.  On a 6 core 3.8Ghz cpu this is around 5% of total.  On the slowest machine (dual core 2.4Ghz) this is roughly 30% of cpu load.

Things I have yet to test:

  • Gen 1 VM's
  • VM's running anything other than server 2012 r2
  • Running the tests on actual server hardware. (hard as most of ours are in production use)

Is there a default QoS or IOPS limit when SMB detects hyper-v traffic?  I just can't wrap my head around how all the tests are seeing an identical bottleneck as soon as the storage traffic goes over smb.

What else should I be looking for? There must be something obvious that I am overlooking!

VMs have no network connectivity after reboot

December 19, 2013, 4:32 am

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.

Slow I/O using Excel 2013

I have written a VBA program that extracts data from a number of small (80K) Excel worksheets. The problem that I am having is with the I/O on these worksheets. Using Excel 2010, I am able to average processing of 3.7 worksheets per second, but when I run the same program on the same computer and the same database using Excel 2013, the the throughput drops to 1.5 worksheets per second.
The slowdown does not seem to be processor related as in a separate test program with no I/O run on the same computer, Excel 2013 is about 15% more efficient than Excel 2010. I suspect that the actual problem is not the I/O time itself, but instead the time that it is taking to display the retrieved workbook that is slowing down the process.
Do you have any ideas on what is causing this slowdown in Excel 2013 and what I can do to speed things up?

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

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?
