Hi all,
I'm planning following environment:
Server 1: Hyper-V Server 3.0 Clutster Node 1
Server 2: Hyper-V Server 3.0 Cluster Node 2
Server 3: Hyper-V Server iSCSI Target SMB 3.0
This scenario has High Availability for Hyper-V Servers, but iSCSI Target Server is a single point failure.
What's best way for make HA iSCSI Target role?
Thanks anyone!

Except something already avaiable in the past, did you see any free and useful tool for file exploring and related basic operations in core mode ?

Hi,
I am having a bit of a problem...
I am using Windows 8 Enterprise x64 as my host OS for Hyper-V - Already joined to a server 2012 domain.
-----------
When making a new virtual network switch - everything works fine - until the time I've installed a guest OS (server 2012 standard ).
---------
I am already using ICS sharing my WIFI connection with the rest of the network.
When I make a new switch I told it - external - and use the physical NIC as the bridge. as that's whats connected to the rest of my internal network.
-----
Soon as I do this - the guest OS has no network connection - even with all IPs set right -
On further inspection my LAN card has lots unticked - like ipv4 / ipv6 etc.
------
It does make a virtual adapter in the middle of those 2 (lan and wifi).
------
so I don't know if this is possible - but can I somehow make it so I can still use my LAN card for internal domain access - and somehow make it use the shared wifi connection still?
------
Any other questions please let me know.
-----
not sure what to do here - and when I use the LAN card for the virtual switch - it stops all ip componants and I then cant even access my internal (physical network anymore).
----- Hope someone can help because I have no idea how im gonna make this work.
ICS must work the same as before using hyper-V as should my normal internal Lan card - or it seems I have big problems.
Thank you for your help

I just bought a toshiba laptop with window 8 and upgraded to windows 8 pro so that I could utilize hyper-v for my old 32 bit program (which worked great in windows 7 virtual machine in the windows XP mode). I then checked all the hyper-v boxes, in the Windows Features, except for the hyper-v platform, which it wouldn't let me. The dialog box says that Hyper-vcannot be installed: virtualization support is disabled in the firmware. I suppose there is another step or 2 I need to do. I can't seem to find any info online. Could someone please point me in the right direction in achieving my objective? I'd very much appreciated it......HubCore
Dear all
Recently we established a test environment consisit of 4 physical servers with 10Gbps network connection.
We use NTttcp to test the network bandwidth between physical servers. By setting the Jumbo Frame, the testing result is over 8Gbps.
But when we use the same way to test the network bandwidth between VMs, the result is only 3Gbps.
Is there any way to optimize 10Gbsp network connection between VMs in hyper-v environment?
Hello,
We have the following problem:
Loss of connectivity guest vM hosted in a clustered environment 2008 R2 SP1 x64 composed of two DELL PowerEdge R410 servers equipped with
network card broadcom BCM5709C (Driver 7.0.11.0) [teaming LAN with two ports for each server]
Is there a solution that fixes this slow Broadcasting MAC address between Hyper-V switch and NIC teaming???
Any idea??

We have a two node Hyper-V Server R2 cluster and are trying to connect a third node to the cluster but when I try and make the connections to our iSCSI SAN the system hangs when trying to mount the volumes. Then when I look on the event viewer for the node there are a bunch of errors:
Source: NTFS, Error: "The file system structure on the disk i scorrupt and unusable. Please run the chkdsk utility on the volume X:"
Then when I try to go in and look at the Disk Management on the new node it won't load.
The cluster is running just fine but I can't get the new node to see the LUNs on the SAN.
Hi
I have recently implemented DPM 2012. The DPM Server was installed as a Virtual Guest machine on a Windows 2008 R2 2 node Hyper-V Cluster. As part of the configuration I installed a Storage Pool based on Pass Through Disks Presented to the Hyper-V Cluster. I have followed the correct procedure for Configuring Passthrough Disks in DPM - however every time a change (Extremely Minor changes) is made to the under lying SAN - such as expanding an unrelated volume or even adding a label to a SAN LUN. The Storage Pool goes Offline with the following error "The Disk IBM 2145 SCSI Disk Device cannot be detected or has Stopped responding" All Subsequent protection activities that use this disk will fail untill the disk is brought back online.
Previously I have had to go back and recreate the Storage Pool and recommence backups. I have no problem getting the storage pool to work - however every single time there is a change on the SAN, the Storage Pool fails, and the Volume hosting the Pass Through Disks goes offline - and we loss backups on the disk.
I'd appreciate if I could obtain some assistance with this issue

How do we do a Virtual to Physical for Hyper-v? Is this possible?
This is not a physical to virtual conversion but the opposite.
Virtual to Physical is the conversion direction. We have a virtual server which we want to make into a physical server.

My ISP provides a static public IP after I establish my PPPoE tunnel. I am going to plug my ADSL model directly into the my server's ethernet port and I want to establish the PPPoE tunnel directly from the MS Server 2008 R2's ethernet interface. My cpanel application that really needs this address is running on Cent OS in a VM on this server. When I setup the VM, I specified that it would be connected to the external interface. So my question is, when I establish the PPPoE tunnel, the public IP will be assigned to my host's interface, will that same IP be assigned to my VM's is interface? Or is NAT happening between the host and VM's interface. I notice that there were some virtualization interfaces established after setting Hyper V so perhaps a private internal address is assigned to my VM's interface.
If so, is there a way to bridge the address to the VM since I am told that NAT will break the application.
If this doesn't work could I use the host to establish the PPPoE session on the physical interface, assign it an "unnumbered" address and bridge the public IP onto the VM's interface?
Or if that doesn't work could establish the PPPoE session directly from the VM's interface and have it traverse the host's interface back to ISP, where the IP address response will bypass the host and end up on the VM's interface?

I have a two-node Windows 2012 Hyper-V cluster with two NICs in each node. Could someone let me know what the best practice is for the network configuration? Should I team these NICs or use them separately? For example, is it better to use one NIC for live migration and the other for the guest virutal machines rather than teaming the NICs? Do the two NICs in the cluster node need to be on a separate subnet? Also, which property settings should be enabled for a NIC that is being used for live migration, and what are the recommended property settings for TCP/IP v4?
Thank you.
I have a physical server setup with many roles. This server is running windows server 2012 standard. I want to virtualize and split up the roles. I have installed the Hyper-V role.
What I was thinking about doing was using the "disk2vhd" tool to convert the physical machine, which is actually the host OS to a virtual disk. I would then like to rename the host machine, change it's IP address and then create a new virtual machine with the same name that the physical machine used to be and attach the physical disk that I created.
So I basically want to move the machine that is on my host OS to a virtual machine. I am then going to remove many of the roles from the Host OS. I want the host OS to just be a DC and DNS Server. I figure the less it has to do, the less often I'll have to reboot it.
Can anyone tell me if this will work the way I'm hoping? Or will this not work.
Thanks,
Nate
I have a new Hyper-V Server running in GUI Mode, with 6 NICs across two cards. The goal is to setup Host then add three Guests for various Windows Server Roles (Exchange, RDS, DC).
Being very new to this Virtual World I have a question about NIC Teaming and Virtual Switches. I understand the basic concepts of both and was working on the assumption that I could create a NIC Team for Host OS to use (using two NICs), then I would use the remaining four NICs for Hosts connectivity. When going about this I thought I would create the NIC Team for hosts then create the Virtual Switch and would of thought I was binding the NIC Team to the switch, but this was not an option in GUI.
Perhaps my strategy is all out, so what is the best solution with amount of NICs? Do I simply bind individual NICs to each VM?
Created a SL 6.1 VM with a single core, 4 legacy NICs on hyperv (win server 2012), and they were passing traffic ok.
Shutdown VM, add an additional core, and power up. Didn't noticed any errors during boot, but after machine is up, the NICs can no longer communicate to the outside - can't even ping the host mgmt interface (connected to one of the virtual NICs via a vswitch).
Remove the additional core, and everything works again.
Since it's very reproducible, I wonder if this is a known issue. Please let me know if I can provide any info to help diagnose the issue.
I understand this is the Server Fourm but I was wondering if some one had a soloution?
Setup
Windows 8
1 x Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller (Ethernet, Physical) << Drivers are up-to-date
1 x Hyper-V Virtual Ethernet Adapter #2 (vEthernet (External Virtual Switch), External Network)
1 x Hyper-V Virtual Ethernet Adapter #3 (vEthernet (Internal Virtual Switch), Internal Network)
The Host OS uses the "vEthernet (External Virtual Switch)" to connect to the internet, and is used also by VM to connect to internet, but the host also has the Internal Network shown under network?
Issue
Eery time the PC gose to sleep and wakes up the Host conencts to the ineternet ok (No Problems), But the guest OS (Windows Server 2008 R2, Windows Server 2012, ect) do not get internet connection, and no matter what you try they will not get an IP Address,
example: -
ipconfig /release & ipconfig /renew
Tempary Fix (Works every time)
I have to run the following batch file (So I can run it remotly) to get the Guest OS to connect to the internet: -
Echo Disable Network Card
netsh interface set interface "Ethernet" DISABLED
Echo Enable Network Card
netsh interface set interface "Ethernet" ENABLED
Why an Issue
Where I work we have staff that show software currently on VMWare Workstation (Cost Allot of Money) and was looking at upgrading to Windows 8 so we can take advantage of Hyper-V, but if the staff have to do this every time they turn there laptops on or wake
them up its not very professional and in turn I cant recomend moving away from VMWare?
