Hi,

I want to emulate the MCITP 2008 network and I notice there are 2 parent disks ie. in the Base folder there is Base10A-W7-Office07-HV.vhd (8,099,552 KB) and in the Drives folder there is Win7-OFC.vhd (1,329,940 KB). What is the point of this?

I've created a fixed Base disk (20,975,616 KB)- maybe should have kept it a differencing disk-  and a child disk (6,580,224 KB) which, I suppose, I could create as another parent, but the size is far larger than the Microsoft WIN7-OFC.vhd. Why is this ?

Thanks, (Confused)James.

Hey all - I just took my 70-659 class, so I am (of course) considering switching my home/lab setup to Hyper-V from ESX.  Thinking about it, I realized there are SO MANY options and I thought I would throw out a semi-poll to those of you who have used it already and/or have experience with many of the options.

SO - I will try to make this as organized as possible, delineating my parameters.  I have just renewed my TechNet Pro subscription, so there are no worries about licensing.

1. Gear

   2 Shuttle Servers with the following hardware:

      Intel i7 870 @ 2.93 Ghz (quad with HT)

      16GB RAM

      3 NICs (1 on-board Realtek 8168, 2 PCI-X Intel 82576)

      1TB Seagate ES.2 HD (7200 RPM, 64MB cache)

   1 ReadyNAS Pro 6 populated with 6 WD 2TB Green drives (variable rotation, 64MB cache)

   1 16-port unmanaged Netgear switch

   1 R6200 Netgear router

2. Current Config

   I've got each server running ESX, and running all the VMs off the NAS via NFS (easier than iSCSI),
   servers clustered together, domain controller as a VM, DHCP on the router.

   As you can tell, this setup is mostly about my laziness rather than performance optimization, so keep
   that in mind please :).

3. Options Going Forward

   I've been weighing some options, and I'm honestly not sure what would be the best as far as flexibility,
   performance and longevity.  I can easily account for performance hits - this is mostly just a lab for me to
   do stuff I'm not allowed to do at work (enterprise, no DC access); that being said, I would like it to work
   as well as possible (obviously).

   I will set out each of the options I've been thinking about, and say that the common change will be
   setting up an iSCSI target on the NAS in order to accommodate clustering.

   Option 1:

      Each server running Server Core 2012 with Hyper-V installed, one actually running the DC instance
      and the other running the DHCP instance.

   Option 2:

      Each server running Server Core 2012 with Hyper-V installed, but DC and DHCP as VMs rather than
      physical.

   Option 3:

      Each server running Hyper-V Server 2012, everything VMs.

I have never been able to get a straight answer out of any of the MS people I've spoken to as far as differences in features between Server 2012, Server Core 2012 and Hyper-V Server 2012, or overhead required to run each of them (thereby consuming host resources I could use for VMs).  The party line seems to be "run Server 2012 in either flavor so you can get the most out of your host", but since I would most likely be using the hosts as pure hypervisors rather than server instances (except for my first option up there), my instincts say using Hyper-V server with management VMs would be the most flexible and leave me with more host resources.

I know many or all of you get paid to do this stuff, so I appreciate your time on it, but rather than scoff at someone looking for free advice, please take it as an opportunity to have fun with a poser, and discuss what you think the benefits and pitfalls are of each technology.

Thanks in advance!

Hyper-V Problems Installing a VM. RDP Error?

I'm new to Hyper-V, but not virtualisation and I'm tasked with setting up a virtual application server under Hyper-V.

All seems pretty straight forward, set up VM, pointed at an ISO to install 2008 R2 server and powered it up. I can see the server booting in the preview window so I double click on the preview to try to connect so I can run through its installation;

Remote Desktop Connection;

An authentication error has occurred (Code: 0x507)

Remote Computer: <fqdn of host server>

OK, what does the event log say;

Event ID: 12480 '<virtual machine>' failure in machine remoting system. Error: 'The client and server cannot communicate, because they do not possess a common algorithm.' (0x80090331). (Virtual machine<VM MAC>)

So this seems to be an issue with RDP not communicating with Hyper-V, even though the VM isn't installed yet?

Any suggestions/ ideas on how to progress?

2-Windows 2008R2 a physical nodes clustered with the hyperV roles installed with back-end FC attached SAN

I have created 2 hyperV Win2012 HA guests on a CSV LUN

Mission:

Create a hyperV guest cluster - install SQL and SCVMM 2012 on the cluster to manage my virtual infrastructure.

Use the cluster to create groups with tiered storage (local & SAN) which would then be used to create clouds with a self-service portal to each.

I am having a heck of a time with this. If I use iSCSI, I create a target name, and add my physical nodes as my iSCIS Initiators Idenitfiers. However, after I clikc next I am forced to pick a resource group (either guestA or guestB). I then create VHDs in hopes of presenting them out to both guests, but cannot.

I am stuck. There HAS to be something I am missing. I'll keep poking around the Interwebs while I await a response.

Note - I was able to use a standalone SCVMM installation to manage my physical cluster, HyperV guests, clouds, and portal etc...but at a recernt chalktalk the MS instructor spoke about how "EASY" this VM guest clustering is to accomplish and this this is now "Preferred."

Never had this problem before, but today am installing some new windows 2008 R2 Standard VM's and I have no mouse control.

says mouse not captured in remote desktop session.

obviously I cannot install integration services as there is no OS installed yet.

I can connect to any exisitng VM, and mouse control works fine, the issue is only occurring when trying to install window son to a new VM.
I presume integration services is supposed to be loaded by the installer.

Normally I only install Web edition and never had this issue before.

Dear all,

I have a setup of two HP SAN and 6 hyper-v nodes divided geographically to two sites 3 nodes in each but in one windows cluster, there is HP san storage in each site and SAN replication is enabled

there is a fiber connection between the two sites so the 6 nodes can access the two SAN storages at the same time

As a test I created a new disk on the SAN storage and replica disk on the other SAN storage then I presented the two disks (primary and replica) for the same hyper-v node   

in windows disk management I found that two disks are appeared instead of one disk as I have in my old setup one of the disks is online and the other one is offline and cant be taken online as it is write protected 

can anybody help why I had two disks shown in disk management console

I am configuring Windows Server  R2 VMs on a Server 2012 Hyper-V host.

The VM's that do not have integration services installed show a VM bus network adapter.
The VM that does have integration services installed shows a Hyper-V network adapter.


Which network adapter type should I be using, and should I be installing the Integration services on the 2008 R2 VMs (if not how do I remove them from the one VM where they are installed?)

Hello,

If using DPM with CSVs it has always been necessary to use a storage device on the Hardware VSS supported list here:http://technet.microsoft.com/en-us/library/hh758219.aspx

Is this requirement the same when using Shared SAS JBOD with storage spaces in Server 2012?

Many thanks,

Hi,

I have a fully working 2 node Hyper-V cluster 2008 R2 SP1.

When a virtual machine with a VLAN tagged is live migrated, connectivity to that VM is lost during the live migration process.
The VLAN is configured in the vNIC properties as recommended.  I have tested VM's that do not have a VLAN ID and they Live Migrate witrhout packet loss.

We have a NIC Team consisting of four NICs (Intel GB Quad adapter) for the VM network which all VM's use.

I have tried disabling VMQ on the team on each host however this doesn't make any difference.

Thanks

Windows Server 2012 with Hyper-V added - all patches applied - not on a domain since it's sitting in my home office.  Live internet connection on both NICs.  Testing on an HP XW8400 desktop, dual Xeon, 8GB RAM, 15K SAS drive for the O/S, and a 2 TB SATA drive for the VHDs.

Created VHDs with both Sysinternals DISK2VHD and Symantec 2011.  Have done multiple conversions to both fixed and dynamically expanding VHDXs, although I think in production I'm going to use fixed since the software development programmers might run the system out of space with a bad SQL job.  Basically tried ever reasonable combination that I could put together.

With either a Windows 7 system sitting at the logon prompt (and same for Windows Server 2003) in the resource monitor see substantial disk I/O.  After awhile when at steady state the max read is about 5,000,000 B/sec and write is about 2,000,000 B/sec per the resource monitor.  Then it varies significantly   Min read ever is about 150,000 B/sec and and write is about 5,000 B/sec.  Nothing else in the system has any read activity and only trivial write activity.  Even if kill the task manager and the resource monitor the hard drive LED just constantly shows activity.

Obviously I understand that it's SATA but still - what is going on?  What VHDX (or VHD) causes the least I/O (especially in an idle system)?

This is really a complaint not a question.  I've been using the free version of VMware ESXi for development testing for years.  I keep reading about how Hyper-V is catching up to VMware in features.  I was excited about the free stand-alone version and decided to try it out.  I downloaded the Hyper-V 2012 RC standalone version and installed it.  This thing is a trainwreck!  There is not a chance in hell that anyone will ever use this thing in scenarios like mine.  It obviously intented to be used by IT Geniuses in a domain only.  I would really like a version that I can up and running in less than half an hour like esxi.  How the heck is anyone going to evaluate it this in a reasonable manner?  I feel like it was just thrown out there so Microsoft could claim they have a free virtualization server like MS?

Steps for free ESXi.

1. Download from website burn to CD/DVD.

2. Boot from disc, follow steps to overwrite hard drive and install.

3. After reboot, config management IP address.

4. Go back to my desk and open my web browser to Management IP and download client.

5. Install ESX client and start running VMs!

Steps for Hyper-V

1. Download from website burn to CD/DVD.

2. Boot from disc, follow steps to overwrite hard drive and install.

3. After reboot, config management IP address.

4. Scour the internet for server tools that install the Hyper-V management snap-in for Win 7.

5. Install server management tools pack.

6. Go to add/remove and enable the Hyper-V snap-in.

7. Open Hypver-V snap-in and connect TRY to connect to box.

8. Receive generic authentication error message.

9. Spend several hours scouring the internet looking for registry hacks, firewall hacks that actually allow you to connect to a damn hyper-v box!

10. Eventually you come across the website/project. http://archive.msdn.microsoft.com/HVRemote

This site walks you through all the script changes/reboots you have to make to connect to bloody hyper-v! 

Here is what I would prefer

I don't want to download any tools at all.  I just want a HTML5 web server on this box that allows me to do everything I can from the  Hyper-V console and doesn't make me configure anything other than a password.  It would be great if it was themed similar to the new Windows Azure Virtual Machines console.  I doesn't have to provide like a built-in viewer to actually interact with the VMs, I would be happy with a remote desktop style connection.

Hello,

I am stuck with Hyper-V Replica.

My Scenario: I have 2 node Hyper-V 2012 Cluster and I want to test Hyper-V Replica. So i had setup a standalone Hyper-V Replica Server for this cluster. I have created a Hyper-V Replica Broker role and Enabled Replication on my VM which was successful. Planned Failover is half success since i have not  configured replication setting in my replica broker role. Planned failover throws a warning that reverse replication is not configured so perform a reverse replication manually.

Now I got totally confused what to configure in replica broker role. Which Primary server and storage are to be configured?

please put me out this.

Hello,

I am looking for information regarding how many virtual machines am I able to run on a Windows 2008 R2 Enterprise server with Hyper-V.  The only information I have found via researching is that it all depends on the RAM installed, CPU, host operating system, and memory allocated for each virtual machine.  How can I determine how many virtual machines I can run at the same time?  Please help!

I'm setting up a new server for a client and attempting to install Hyper-V Server 2012.

When I turn on 'Embedded SATA RAID' within the BIOS settings on the ML330 G6, the Hyper-V installation cannot find any available disks for the installation to proceed. I searched for drivers for the 250GB SATA drives that are installed to no avail. I installed Windows and it can see the RAID1 array perfectly fine.

Upon turning off the 'Embedded SATA RAID' function in the BIOS, the Hyper-V installation can see both drives. Hurrah. But now I can't use HW RAID :(

I've turned 'Embedded SATA RAID' back on and tried the Hyper-V installation once more, again no drives available.

What's the go? Hyper-V doesn't support HP's Smart Array controllers, or this controller specifically? But Windows does??

I have 2 servers running 2012 standard gui with Hyper-V enabled. They are on a domain. I have followed instructions for enabling remote mmc management on the microsoft site, but it still doesn't work. If login to one of the servers and try to manage the other in hyper-v, or try to move a vm to the other, it fails. The error i get is that the rpc server is unavailable. If i disable the firewall on both machines, it works just fine.

So what I'm trying to determine is how many servers (total) I can install with a Windows Server 2012 Standard license.  Am I correct in that I can install a host operating system and then two more additional Virtual Machines after installing the Hyper-V Role making 3 total servers?  Or does the Host OS count as one of the licenses only allowing a single additional VM to be installed making 2 total servers?

The thread below is a response that can be found all over the Web but I'm still not 100% clear.
