Hi Friends...

How to mount USB Drive to the virtual machine...

base 2012 is loaded on the hardware and 2003 VM is created on that using hyper-v. Now iam trying to mount USB Drive to 2003 VM but it not happenning...

help out to solve this case.....

I want to set up a Windows 2012 Server running Exchange 2013 as a VM in a Windows 2012 Essentials domain (Essentials is also running as a VM in Hyper-V.  I also want to install SQL Server 2012 on the Essentials server.  I have an extra server to split the workloads but was planning on using one server for everything. Is this feasible and will it work?  Any help would be appreciated.

Hey guys!

This is my first post/question in MS forums ever; it is also a question that has been ask before for Hyper-V on W2008 R2 and probably on W2012 as well, but I find it very confusing. This is the deal:

We are currently building a two node Hyper-V environment on HP G5 Proliant Servers with 2CPU, 32 GB RAM and six 300 GB SAS 10k disks each. This environment is not going to use any SAN storage and will initially host two VMs on each node, namely a MS SQL Server 2008 R2 with a very low load (10-15 users) and a file server (40 users). There might be also another VM running Veeam Backup. The hosts have the HP Smart Array P400 Controller and we were planning to build one logical volume in RAID 6 for a total of 1.2 TB and then at the installation time for W2012 create a partition for the OS of say 100GB and leave the rest for another partition to host the VHDX files. My questions are:

1- Is this a good strategy? What the shortcomings or disadvantages of this setup might be?

2- If the described configuration is OK; what about configuring a separate partition for the page file for the host OS? Will that provide any extra benefits?

Eventually these hosts will have each 4 VMs, the two mentioned above plus other file servers. On this note, will it be better to set aside some extra disk space dedicated just to file serving directly from the host (with the File Server role installed) or a dedicated VM with the File Server role is a better solution?

Thanks,

Ricardo.

I run Windows Server 2012 RTM Hyper-V and I can occasionally not access the second virtual hard drive (dynamically expanding VHDX) attached to the VM through the virtual SCSI controller. I can however access the first hard drive that is connected with the virtual IDE controller.

I get the following warning in the event log under “Administrative Events” every 30 seconds when this happens:

• Log Name: System
• Source: Storvsc
• ID: Storvsc
• Message: “Reset to device, \Device\RaidPort0, was issued.”

I get this error once or twice a week and it has caused serious problems since one of the virtual servers that have this problem is a fileserver and the second hard drive contains all the data.

The only quick solution to the problem that I have found is to force the virtual machine to stop using the “Turn Off” feature since a normal shut down does not work (stops at shutting down the event log or similar) and then start the virtual machine again.

You can also wait for about 30 minutes or longer until the disk for some reason becomes accessible again by itself.

My research into this problem shows that:

• Only 2 of the 10 VMs running Windows Server 2012 RTM that I have, have this problem.
• Both these VMs have a second virtual hard drive (dynamically expanding VHDX) that cannot be accessed for 30 minutes or longer.
• Check Disk of the virtual hard drive shows no errors.
• The second hard drive is attached to the virtual SCSI controller.
• I can find no problems at all with the physical storage on the (not related) 4 hosts that I have. The problem exists only in the VMs.

I have now attached the second virtual hard drive to the virtual IDE controller to see if this permanently fixes this problem (i.e. does not happen for at least a week).

Is there something wrong with the virtual SCSI controller or the virtual SCSI device driver that comes with Windows Server 2012 RTM? Does anyone else have this problem?

Hi guys I'm looking to setup a Hyper -V environment containing a domain controller which will have WDS/DHCP/DNS server which is completely private of the Host Domain.

The Host is not on the domain but has a static IP with DNS pointing to our network.

My Virtual DC and clients can communicate together using a "private virtual machine network" however they do not have access to the internet.

I don't want to assign a internal network as that then allows the Virtual DC and client see our HOST Domain. (Can ping the domain name as DNS is on the HOST Server.)

Any one have any ideas how I can route only internet to the vm's without them seeing the host domain or even the domain seeing those Virtual clients?

I understand External network will provide full visibility to the domain

Internal will allow visibility via the HOST Server (which is off the domain) but DNS will allow visibility to the network?

Private is completely private which is ideal but no internet access :(

any ideas please

In the HyperV Hypervisor Virtual Processor Counters there is the %Guest Run Time Counter that gives me a percentage value. Is there any way to get a value in milliseconds? I think i could convert it with the knowledge of the time frame for the measurement. My calculation would be: TimeFrame * %GuestRunTime / 100.

Does anyone know how long the timeframe for the measurement is?

If we have a converged network with two teamed pNICs in LBFO on windows server 2012 Hyper-V node, Teamed adapter is assigned in vSwitch used for tenant, management, live migration, cluster and storage networks, can we enable RSS on the pNICs to leverage CPU performance for the Storage network or everything attached on the vSwitch can only leverage from the DVMQ?

I guess that everything attached to vSwitch is considered as vNIC and the answer is that DVMQ must be used instead of RSS to receive some additional performance and system offloading but I prefer to have your opinion.

Thank You

I'm getting this error and not sure how to proceed yet. As seen in the screenshot below I've had 282 out of 285 successful replications.

The three errors are as follows.

Hyper-V suspended replication for virtual machine 'XAVIER' due to a non-recoverable failure. (Virtual Machine ID 554B5DA9-139C-4207-80B9-5E7E9CD8FAD3). Resume replication after correcting the failure.

Hyper-V could not replicate changes for virtual machine 'XAVIER': The device does not recognize the command. (0x80070016). (Virtual Machine ID 554B5DA9-139C-4207-80B9-5E7E9CD8FAD3)

Hyper-V suspended replication for virtual machine 'XAVIER' due to a non-recoverable failure. (Virtual Machine ID 554B5DA9-139C-4207-80B9-5E7E9CD8FAD3). Resume replication after correcting the failure

Here is the scenario:

We have a Windows 2008 R2 Hyper-V Server and we have a problem with the VSS writer on the server.  The problem is seen when attempting to perform backups on the machine (we have used Symantec Backup-Exec as well as Acronis).  When a backup starts on the host, the job just freezes and no information is reported on the server doing the backups except that it times out.  On the Hyper-V host, when doing a "VSSADMIN LIST WRITERS" command, everything comes back as: State: [1] Stable, Last error: No error, when no backup has been attempted however when you have attempted a backup, it just freezes and doesn't report back anything at all.  In order to fix the freezing a reboot of the host is required.  Additionally, on the reboots I've noticed a stream of "Hyper-V-Integration-Data-Exchange" errors (Event 4096), Hyper-V-Integration-Data-Exchange) - The Data Exchange integration services is either not enabled, not running or not initialized."  (This is only seen during a reboot.) 

Thanks!

Hello folks,

I have a virtual windows server 2003 acting as a FTP server. This guy has been BSOD'ing more and more frequently I have generated the mini dump report. What I get from these mini dump reports is always the same, DEFAULT_BUCKET_ID:  DRIVER_FAULT, PROCESS_NAME:  dllhost.exe, which tells me that a driver failed related to dllhost.exe. Now I believe that dllhost.exe is related to COM+ but that's as far as I know how to troubleshoot.

Hi:

I've set up a test site with Windows 2012, Hyper-v, both servers in a workgroup so I'm using Certificate based replication.

Both servers have the same Root Cert in the Trusted roots, the same Issuing Cert (signed with the Root Cert) in the Intermediate CA store, and an end stage cert, with private key, in the Personal store with the CN=machine.domain.com. None of the certificates are listed as expired in the published crls. 

The certificate mmc snap in shows the cert chains and all certificates as valid.

Certutil shows both setups pass the encryption test.

Both have Key Usage: Digital Signature, and Enhanced Key Usage: Server Authentication, Client Authentication and Secure Email.

Replication setup finds the certificates and all is good until I select finish when the error is issued stating, in part,

Enabling Replication Failed Hyper-V could not validate certificate with thumbprint (thumprint of local cert). Enhanced Key Usage invalid. etc etc The Enhanced Key Usage should have Client Authentication. Error: The certificate is not valid for the requested usage. (0x800B0110).

Given that the certitfcate snapin readily sees that Client Authentication is one of the Enhanced Key Usage selections I'm guessing the problem is something else, but I can't see what.

Any help with this would be greatly appreciated.

So.....

I just tried the MakeCert route, created a root cert, and a machine specific cert, installed on the sending server, checked that they are in the Personal and Trusted Root stores.

The replication is working now with the Makecert certs and the validation turned off. This works for now but I'd like to fugure out the issue above to get this working properly. I have compared the Makecert and real certificates and can't find a material difference.

I was playing around with Hyper-V but I didn't see an option to clone VMs.

Is there any way to clone VMs in Hyper-V

What is the best storage configuration for a single host server.  

Normally I've seen a RAID 1 for the OS and another RAID 5 or 10 configuration for VM Storage.

We are trying to reduce costs and planning on removing the RAID 1 leaving a single RAID 10 with the OS and VM storage on the same array.  Any thoughts on having a single array vs having two to separate the host OS and VMs? 

I would like to know the best way on doing an upgrade\migration from a 2 node HA cluster with 2008R2 to 2012. What I need to have done is to place the new 2012 hyper-v server as the initial server and then migrate the guests to the new 2012 server. Which would create a single node cluster. I would then want to do a clean install of 2012 server on the other 2 nodes and join them to the cluster. The only problem is that we only have one ISCSI SAN that we are currently using with the 2 node cluster. Would I need to recreate the cluster to allow 2012 to join? If not can I connect to the same cluster with all of the 2012 and 2008r2 nodes connected?

These node servers each have 1.5TB of storage that is local and it would accommodate the move of the guests for the time being. Would it be wise to move the guests locally off of the SAN then move them back when all is ready and in place?

Should I reformat the CSVs drives so that ReFS would now be in effect on the SAN?

I know that the process that I have in place will remove my ability to Live migrate until the other nodes are in place but I really have no choice.

I am trying to find the best way to accomplish this.

Thank you for your advice.

Hi guys,

My test bench is Standard (GUI) Windows Server 2012, specs as follows:

• Asus Z77 motherboard with 8GB RAM, Intel i5 processor
• Single NIC - onboard Realtek GB ethernet controller
• Latest patches loaded
• Workgroup mode
• File Sharing enabled
• Testing Hyper-V with a single VM running Windows 8 (2 cores and 2GB RAM assigned)

My basic intention, other than investigating Hyper-V, was to test software in the VM. My last test machine was Windows 7 and by the time I retired it the entire desktop (at 1920x1080!) was covered with shortcuts for various bits of shareware and technical manuals. This time I thought I'd be a bit more organised :) but back to the problem...

I've noticed that at random intervals - between 30secs and a few minutes - the network connection on the VM drops out for about a second. I've left the Task Manager running on the VM with the network activity and what I see, via a standard RDP connection from the host machine, is the graph drop off for a second but the CPU and other graphs show no drop outs so it's not the VM freezing.

Things I've tried:

• Disabling the TCP offloading settings for the Realtek in Win2012
• Creating a Virtual Switch with and without the SR-IOV ticked
• Turning off the hardware acceleration features of the VM from Hyper-V

From staring at the Task Manager for some time it seems that the drop outs are more frequent under higher loads within the VM. I deliberately tried downloading some Linux ISOs via torrents as I know these are pretty severe tests of network connectivity. If I were to guess I'd say the graph has to go over 1Mbps to get the drop outs.

I would like to know, if anyone would be so kind as to enlighten me, if there are any other things I could do. For instance:

• Any other NIC settings or maybe some registry edits I could try?
• Is the Realtek a dubious item to have on a server? Should I try adding another NIC card to my test rig?
• Is it okay to share the NIC between Win2012 and Hyper-V? Should I add another NIC anyway just for the VM?
• Will any other NIC do (in the context of it being a non-production system) or are there any particular brands to recommend?

I think I have a Marvel-based PCIe card in the parts bin at work if that'll do.

I eagerly await the advice of the Wise Masters :)

Andy

I have just installed openSUSE 12.03 in a virtual machine box under Microsoft Hyper-V on Windows 8 Pro.

I attempted to change the resolution from 800x600 to something more acceptable, but under Display and Monitor configuration, there are no other options than 800x600.

Microsoft's website says that openSUSE 12.1 is a supported operating system with their Integration Services built in. This should, I would think allow me to utilize the full range of resolutions for the display adapter in my machine. I say this because all my other guest operating system installations work fine with the complete range of resolutions available for my display.

I have also installed Ubuntu 12.04 and CentOS 6.4 as well as Windows XP, Vista and 7 and none of these other installs gives me similar problems.

Is there a known problem with openSUSE in a Hyper-V V-Box with respect to resolution?  I have noticed several similar posts in my web searches, but no good answers that shed light on this problem that is apparently not mine alone.

I am running an Intel Core i3-3220 with an Intel B75 chipset motherboard that uses the Intel default graphics available through that board/cpu on the physical system.
Thank you in advance for any help you can offer

I'm checking out some new features of 2012 and have 2 standalone servers (not clustered) attached to their own storage (10Gb iSCSI). I've got a dedicated live migration network between the two servers as well (10Gb). I created a dummy VM on server #1 with a few VHDs. Shared nothing is working but I have some questions about if my setup is correct, based on what's going on.

Issue #1 - The migration seems to take a long time and isn't using my available bandwidth. I have 10Gb everywhere but the data is moving through the systems at only between 800Mb - 1.5Gb throughout the whole process. We have great tier1 san (ssds, 15k sas) for our sandbox, so I know the source and destination storage aren't stressed. The data path looks like it comes off storageA via iSCSI into server1, travels over the migration network to server2, and then is pushed out to storageB via iSCSI.

What is the holdup? Why isn't it moving faster and using more of my 10Gb links?  My only thought is that since shared nothing is using SMB 3.0, maybe SMB is throttling things? 

Issue #2 - Possibly related but I'm not sure. I have multiple VHDs on my VM (one per lun for simplicity).  In perfmon as I watch the migration happen, those VHDs are moving one at a time. The destination machine writes to the first LUN only (with no activity on the others), then upon completion it starts writing to the next lun, and so on.

Is it limited to one disk copy at a time? Can it not do parallel copies during shared nothing migration?

So in 2008 R2 I pretty much shutdown every single NIC feature, such as Checksum Offload, TCP Offload, RSS of any kind, VM queueing and auto tuning.  I did this based on problems I had and many blogs and or posts by people on this forum.

I will have new hardware arriving soon and I finally finished my SCVMM 2008 R2 to SCVMM 2012 SP1 migration (painfully).  I will be installing Windows 2012 on these new servers and I was wondering has anything changed?  Is the "best practice" just to shut this stuff off to be safe?

Thanks, -Lindy
