Server 2012 R2 Hyper-V and Drivers
Hello all,
Question is regarding drivers on our Dell Systems we are deploying for use in a MSFT 2012 R2 environment. Some of the systems are showing requiring NIC driver updates from Dell. I'm a little leery of replacing the MSFT drivers with Dell Drivers so want to hear back on recommendations. I'm concerned that MSFT may not have tested fully the drivers and/or Hyper-V has been tested extensively using MSFT drivers versus vendor NIC drivers.

sharing host to guest, large-ish (500MB) file, virtual internal vs physical NIC
Hi,
small business <10 people with a small server running 2012 R2 doing DC, file serving and hyper-V with 2 guest VMs, 1 running a small db app on one of the guest VMs (quickbooks enterprise DB) and the other running an old internal single-user progam we
need for (!)
as the root is acting as a file server (although this is easy enough to change but I dont want too many VMs as its not exactly a monster of a server or anything), the guest VM needs to access a largeish shared file which is currently stored on the root and is accessed via a share.
This file is currently 450MB and is the quickbooks company file (no, it wont shrink any more).
Whats the best way to setup this file ?
1) as it is on a share on the root, that the guest VM accesses as a share using the virtual adaptor
2) inside the guest VM vhdx ?? (a bit scary).
Will #2 faster or slower (assuming it were all to end up in the same RAID array as it it were on the root but now inside a vhdx) than accessing via virtual switch to a share on the root (same physical raid array but over the virtual switch layer as opposed
to the vhdx layer)
if #1 is faster, I assume I get better performance if the guest VM access the shared file from the HOST via an internal virtual switch vs dedicating a GB NIC (via a virtual switch that does not include the host NIC) to the qb guest VM and having it communicate via actual wires to the host (surely the internal virtual switch has to be faster)
what if guest vm and host share an external virtual switch, is there any performance difference in terms of guest accessing host if the host is also using external switch for other network jobs ?
should I setup a) internal virtual switch for just guest -> host operations and then b) use "dedicated" NIC for guest -> external and another for host->external ?
is there another, better way ? i.e. qb server on the root, not in a vm, accessing local file on the root

File service gone after moving virtual machine in Hyper-V
We have file server virtual machine with vhd system disk and connected data on physical drive. All users (800) have folders on the attached disk. After exporting and importing virtual machine to the new Hyper-V file service is gone. We moved the data disk too the new machine too. What we are doing wrong? I tested also just copy vhd and create virtual machine, but we encounter the same problem. We was forced to recreate shares manually (script). Why file service is not preserved??

Hyper-V 2012: Replication fails to automatically resume after a server reboot
Hello,
I have a VM lab with Windows 2012 and Hyper-V. Overall it has been awesome, but I have one small glitch:
The VMs on server A replicate to server B. The new Hyper-V replication feature works perfectly, except for my one problem. When I shut down and then restart the servers, replication does not always automatically resume for all VMs. Some VMs will resume replication on their own and some will require a manual resume - and it seems to be random. I can always restart replication by right clicking and the hitting Replication --> Resume Replication, but I rather hoped that this would happen automatically, all of the time.
Has anyone else experienced this? Is there a cure?

Why virtual interfaces added to ManagementOS not visible to Cluster service?
Hello All,
I"m starting this new thread since the one before is answered by our friend Udo. My problem in short is following. Diagram will be enough to explain what I'm trying to achieve. I've setup this lab to learn Hyper-V clustering with 2 nodes. It is Hyper-V server 2012. Both nodes have 3x physical NIcs, 1 in each node is dedicated to managing the Node. Rest of the two are used to create a NIC team. Atop of that NIC team, a virtual switch is created with -AllowManagementOS$False. Next I created and added following virtual interfaces to host partition, and plugged them into virtual switch created atop of teamed interface. These virtual interfaces should serve the purpose of various networks available.
For SAN i'm running a Linux VM which has iSCSI target server and clustering service has no problem with that. All tests pass ok.
The problem is......when those virtual interfaces added to hosts; do not appear as available networks
to cluster service; instead it only shows the management NIC as the available network to leverage.
This is making it difficult to understand how to setup a cluster of 2x Hyper-V Server nodes. Can someone help please?
Regards,
Shahzad.

Hyper-V VM Windows Server 2003 R2 SP2 Network Problems
Hi Guys,
I am trying to setup a new VM in my lab (I am using windows 8.1 in my host) with Windows Server 2003 R2 SP2. I already installed the integration services in that VM, the network adapter is ok (Hyper-V network adapter). Well, everything it seems to be ok, but my W2K3 Machine keeps getting 169.xxx ip. My host is wireless , the virtual switch is ok, since I have other 4 VM (W2K8, W2K8R2, W2012, W2012R2) working fine with that switch and having access to the internet, just this VM with W2K3 is not working.
Do you guys can help ?
Thanks

WMI class for Hyper-V Virtual Storage Device
Hello,
I am working on script to calculate disk latency in hyper-v environment using WMI.
I don't find any WMI class which gives me read and write latency for virtual disks.
However, there is a perfmon object "Hyper-V Virtual Storage Device" which gives required counters.
Please let me know corresponding WMI class/Namespace for this counter.
Thanks,

failed to start worker process: server execution failed
I've been trying to get windows phone 8 emulator working with no luck. This lead me to find out that it's not emulator problem, but hyper-v itself. I installed new VM and when starting it, I'm getting the following error after it attempting to start for
about 5 minutes:
"Name" failed to start worker process: Server execution failed (0x80080005)
I've checked cpuid for compatibility with virtualization (vmplayer works ok)
I don't see anything in windows event log, but Hper-V-Worker/Admin log has the following entry:
The Virtual Machine Worker Process has lost its connection to the root\virtualization WMI namespace: General access denied error (0x80070005). As a result, some WMI operations may not function correctly. To correct the problem, try restarting the Windows Management
Instrumentation service.
and Hyper-V-VMMS has the same message as above about worker process not starting.
I've tried re-reinstalling hyper-V with no success.
Thanks for any help.

Local Disk Volumes question
Hi,
My Hardware is HP DL380 Gen8 with four 146 Gig disks. I'm planning to install hyper-v 2012 r2 on this machine and create two virtual machines. Could someone recommend how the four disks be best utilized for virtualiation?
If I leave the two 146Gig for the two VMs, when I create the VMs is there an option what disk the VMS be placed or something like that. Coz, on my first try I left two 146Gig for my VMs and when I created them I am only presented what folder should I place the VM files, etc...I am not sure if the two 146gig disk that I allocated has been utilized.

Virtual Switch Weird Performance
Hi hoping someone can point me in the right direction here. I have an underperforming external vswitch.
I am testing using Lantest (Client Server) so using memory to test throughput so storage is taken out of the equation. Setup is Hyper V 2012 r2 cluster (2 node) patched. I have removed antivirus and firewall is disabled. I have been through all turn off VMQ turn of offload etc over the past few days, and nothing makes a difference. Here are the figures that are odd and not up to par with what should be happening. NIC's are Intel I350-T4 using latest Intel Driver, VMQ disabled but all other offload enabled. All integration services are up to date. I have tried using the latest drivers, the 2nd latest and the MS one.
Test physical server (not HV Host) to NIC on Hyper V Server (assigned to external vswitch) - 800Mbps read 800Mbps write
Test physical server to virtual guest (2008 R2) 120Mbps read 750Mbps write (odd the write is different here) so its my guest receiving traffic which seems sluggish.
Test physical server to both nodes external vswitch NIC (after enabling allow management to share) 800Mbps both ways
Test VM to VM on same host on private network 125Mbps both ways.
Test VM to VM each on separate host using external vswitch around 125Mbps both ways.
VM performance is great within RDP session, low cpu low diskq etc. Networking latency is good, but throughput is terrible,
There is no bandwidth management set within guest settings, there are no QOS policies set. If I do throttle the guests using bandwidth management I can see that working. If I remove it I get the figures above.
Seeing I can get great performance using the NIC that I have assigned (its actually now a team, tested it single and teamed) the only factor that sits in the middle is the vswitch. Considering the poor performance with a private switch which should absolutely fly, there is something horribly wrong, or something I have overlooked.
Thanks for reading, hopefully someone can point me in the right direction.

1st VM can connect, but second cant??
I have a Windows 2k12 host server where I've installed Hyper-V and have 1 VM running. I configured a virtual switch attached to the physical NIC of the host server and was able to configure the static IP and gateway to get internet on the child system.
Now I'm trying to make another child system and I've duplicated the same exact settings, except IP and MAC address of course....and this VM is not able to ping the gateway of the host, or the host...and of course not reach the internet. Can someone tell me
whats going on? Why can one child reach the internet and not the other? I've disabled all firewalls just to remove that as a possibility...but what could I be missing? I repeat, both child VMs are identical twins with the exception of their IP addresses and
assigned MAC IDs.

A port on the virtual switch has the same MAC as one of the underlying team members on Team Nic
Experts !
Windows 2012 R2 Cluster.
2 Physical NICs dedicated for Hyper-V data traffic. These two NICs are used to create a team using Windows teaming (Switch Independent + HyperV Port) and this teamed interface is used for HyperV Virtual Switch.

While I did the same configuration using SCVMM for my Windows 2012 HyperV clusters, the fabric was deployed from SCVMM and hence the team and the virtual switch was just one. In the similar way, How should I do this with out SCVMM ?

Xendesktop 7.1 - Connecting to Provisioning Services - Please wait
Hi,
We have a problem with Hyper-V 2012R2 and Citrix Xendesktop 7.1:
When PXE booting our VM's we get a delay from 1 minute before the connection to the PVS server will be made and the vDisk will be found. It shows:Connecting to Provisioning services. Please wait....
When we take a 2012 server instead of 2012R2, everything works fine and fast...
What's changed within 2012R2 what could cause this problem?
Somebody?
Kind Regards,
Kris

RE: virtual machines going offline and virtual disks going offline when Netgear router is restarted (physical router connected to ISP)
Hello everyone I am currently running a 2 node microsoft windows server 2012 failover cluster and i have a funky issue that is happening ONLY when the physical router connected to the WAN is restarted. a bit more information to help with trouble shooting: 2 nodes (identical in specs/build) are connected to 1 synology NAS where i have created the iscsi luns that are mounted on the 2 nodes via mpio (round robing w/ subset). Every thing runs smoothly until the physical netgear router is rebooted from time to time.
When i reboot the router the virtual disks in the cluster go offline and so do the associated virtual machines. They will only come back online when the router is up and running once again.
Any ideas on what can be causing this ?

No Boot from USB Support
I have been looking for a logical method to use to boot from USB for Hyper-V, as I would like to test a new boot sequence I have placed on it before attempting it on an actual computer, but there is no sure method to allow me to do so and myflash drive doesn't support diskpart => offline. When will this issue be addressed?
With the Tech industry of boot media abandoning booting from CDs and should I even mention 3.5 floppy? Why has such an integral method of boot media been ignored in a brand new piece of software that for all intent and purposes should DEFINITELY support booting from USB Flash?
I would love a Microsoft Expert's official answer on this if you would please, thank you
