SLES 11 SP2 autoyast under Hyper-V 3.0 (WS2012)

It took me some hours to realize that SUSE Linux Enterprise Server 11 SP2 is the only supported SLES under Hyper-V 3.0 (from a WS2012 support list page). And another 2 hours to find only VHD hard disk is recognized by SLES 11 SP2: VHDX will not roll.

I have managed to deploy RHEL 6.2 VM via kickstart script from the IIS web server in the host OS, with this kind of parameter:

linux ks=http://x.x.x.x/kickstart/rh65.cfg

The only thing need to mention is, RHEL can only recognize "legacy" NIC emulated by Hyper-V during setup.

I created some autoyast script for unattended setup of SLES 11 SP2. But the guest OS alwasy complain about cannot found the URL, when I pass the paramater to installer:

autoyast=http://x.x.x.x/autoyast/autoinst.xml

Neither default NIC, nor legacy NIC will sovle this. Is it possible to do an unattended setup of SLES 11 SP2 via http?

I know there may be other options to do this:

• create customized SLES DVD, put the autoinst.xml inside the DVD, and pass on file://autoinst.xml as parameter
• create a virtual floppy disk, put the autoinst.xml in, and pass on floppy://autoinst.xml as parameter
• Send key inputs via PowerShell script, using the type methods (TypeText, TypeKey...) of msvm_keyboard(http://msdn.microsoft.com/en-us/library/hh850165%28v=vs.85%29.aspx)

Are these 4 options feasible?

So is there an MMC GUI I can get installed on the Core server and run from a console seesion on the physical server or RDP session to the Hyper-V Server 2012 Core?  I have worked extensively with Hyper-V in Server 200R2 but always in the "full" install so I had a GUI.  Never worked with Server 2008R2 Core.  Thanks for your help.

Hi there,

We are trying to configure shutdown and startup process for Hyper-V failover cluster in the event of power outage. 

There are two nodes in the cluster. What we want to achieve is:

• shutdown virtual machines on node1
• shutdown node1
• shutdown virtual machines on node2
• shutdown node2

Can I please get some help on how to configure this sequence using command line?

Thanks

Winnie

Hi, need some input please.  Where I work, there is a Microsoft 2008 R2 Enterprise server that’s got Hyper-V running with 4 VM’s – there is no SAN or storage solution – all running on this server.  I have been asked to set up another Hyper-V server as a ‘backup solution’ to the VM’s on the first host Hyper-V– with no SAN or storage solution – and I’m against the idea – because there is no SAN or storage solution.

What would be the risks in setting up this type of scenario?  I need something to take to the table when I'm asked again, please.

Thanks

Hi all,

I've a two node Windows 2008R2 SP1 cluster with Hyper-V. I've several virtual machine on the top of this cluster. If I configure an automatic start action for a virtual machine (for example I set to "auto start") and then I live migrate the VM to an other node, I loose the setting. It is resetted to "no action".

I've tryed to configure the setting via Hyper-V, via SCVMM, via FailOver Cluster but the setting is always not retained! Is it a bug?

Hi everyone.

We are about to implement a 2 node Hyper-V cluster, but we are having an internal discussion about shaving $$$ of the implementation.

the biggest area is around the Cluster/heartbeat and live migration VLANs.

The use of a switch or direct crossover cables are both widely used, but i have heard there are issues with the use of crossover.

What is the official supported method by Microsoft or are both configs supported?

Any documentation to back this up?

Obviously not having to buy 2 switches for extra redundancy is appealing

Many thanks for your help

Hi,

     Now that we are planning to virtualise our Domain Controllers. we are going to use Hyper-V for the same. 

what are all the basic points that i need to keep in mind before planning to virtualise. there are six domain controllers

1) when we set up DC on a Virtual platform, will hyper V can with stand the maximum I/O operations 

2) consider we are going to user Hyper -V cluster where it goes as Active - Active cluster

Hi People.

putting a DR plan to a customer and this involves server 2012 HV Replication.

they have 2 servers already which I want to use.

My question is can I replicate to a lower spec server?

e.g. the LIVE SBS will have 16GB of ram but the replication server may only be able to supply 10GB.

can I just change the settings on the replica server then fire up the VM?

Thanks in advance

James.

Hi guys! Little confuse on licensing please help and advise. I have running just Hyer-V services Server 2008 R2 EE. It said right here http://www.microsoft.com/licensing/about-licensing/virtualization.aspx that I can run 4 instance guest on hyper-v host. Is this means I cant moved / convert a physical server 2003 R2 and add it on the existing hyper-v host as a guest it will be my 5th guest server.

Hello, I am currently in the process of upgrading a Server 2003 VM (Hyper-V) that is a DC, to a 2008 Hyper-V and will also promote it back to being the DC. There is one other DC in this AD structure, that is on another Hyper-V host.

The Host system runs on 2008 server core. There is another VM on this same host that is an apps server.  The DC (2003 hyper-v) system currently has a low OS disk space, and I want to tackle that when I do the upgrade install.

I also want to move away from the Server 2008 CORE install, to possibly a Server 2008R2 on the Host and then install my Virtuals - one DC & one APP. I’m not sure if the client will go for this right now, but they do want to upgrade the Server 2003 DC VM to a Server 2008 DC VM.

What versions should I be considering? Any known issues? What precautions should I take.

I look forward to your feedback.

I have a hyperv box (W2K8R2) that has been running fine for quite a while but has started to hang on me the last couple of days.  It is configured with 2 nics (one dedicated to the host and the other to hyperv).

I went through the event log looking for something odd and I found a bunch of warnings stating " Port 'SWITCHPORT-SM-D3CAF5D4-BC6A-4397-AEA7-75E293C1FB50-0-1' was prevented from using MAC address '00-15-5D-03-01-03' because it is pinned to port '6FFF5F48-F8DE-4073-A'. "  One of the strange things about this warning is that this box is configured for hyperv to use MAC addresses in the 02-00 to 02-FF range so I don't know where the 01-03 is coming from.  There is a huge number of these warnings - sometimes as many as 12 per second.  What is causing these?

Thanks

Hi there,

I have a two node Hyper-v cluster on Windows Server 2008R2+SP1 with cluster shared volumes.

I want to add a new third node.

On this third node I already connected the witness disk. It is showing in Disk Management as offline.

When I run the validate a configuration wizard it fails with "No disk were found to perform cluster validation tests."

From the LOG:

Disk with identifier 73588c7 has a Persistent Reservation on it. The disk might be part of some other cluster. Removing the disk from validation set

No disks were found on which to perform cluster validation tests. To correct this, review the following possible causes:

* The disks are already clustered and currently Online in the cluster. When testing a working cluster, ensure that the disks that you want to test are Offline in the cluster.

It says me what to do, but how do i do this correctly without interrupting the cluster?
Can I altually do this while the cluster and VM's remains 100% operational?

Thanks in advance,
John

I have successfully set up WD Passport USB drives as passthrough drives to Hyper-V guest systems.

Offline the disk in the host, add it to the VM settings and it appears as a SCSI disk in the guest OS.

Now trying to do the same thing with a SAMSUNG S2, and it does not appear in the guest OS. The host sees it, I can offline and online it, and add it to the SCSI controller in the Hyper-V manager. The guest Disk Management does not see it, so I can't use it.

Hi,

I have a dell poweredge 2950 machine. I am planning to install four VMs. Is there any easy way to replicate the VMs after I created on virtual machine. Can I copy the vhd and attach to the new machines. Is it advisable. Is there any issues if I copy the same VHD for the other three machine. Please advice

Are there any specific recomendations for moving a VM to a new HyperV 3.0 2012 platform? I have a number of VM's on 2008 R2 and I am happy to move them 'offline' is there any additional process or update for the VM when it is moved onto a 2012 HyperV 3.0 server?
