I have a problem with the Azure Stack deployment.

It seams like the scripts fails in the process installing Hyper-V on  my host

I have tried to just deploy Hyper-V from the Powershell promt, and the initial install is fine

But after that the Server reboots and tries to add some updates/features and after app 10 min it fails, reboots

and uninstall the cahnges again, and after that reboots again, and is back to normal...

Any inputs will be nice

Hi All,

I have Oracle Unbreakable Linux 6.5 which runs Oracle ERP application & Database it has three VHDs 80 GB , 600 GB and 120 GB on daily basis it creates RMAN backup approx 32 GB which stores on 120 GB VHD.This VM has more READ operations and around 1 MB / 1 Mins Write Operation other than Backup.

I have enable Hyper-V Replication on this machine with 60 Sec Cycle Exclude 120 GB VHD where RMAN data places but i have found that replication is not going on normal.

I can see that hyper-V replication fully utilizing 4 MB to 5 MB.

My Question :

1.If i excluded 120 GB VHD and i have very little write operations on replicating drives so why replication is not normal

2.Is read operations have impact on replication

UUGGHHhhh... I am an IT student with a bit of a challenged learning ability...apparently.  I'm Learning Windows Server 12R2 and we are using Hyper-V environment in class.  I want to set up a training environment at home.  I have the needed ISO's and am great with installing them.  What I cannot get configured is the Initial Network connections between my Virtual Switch, My V-Server (which will be my parent domain) and my Host computer.  I want to have normal daily internet connections on my PC (WIN-10-Pro) and have my virtual network utilize the host PC's NIC/Router for network connections and be able to connect to the internet...but remain private.  I believe this is considered an "internal" connection.  Where there is great frustration is the IP settings.  my ISP has me set up for automatic DHCP, and my DFGW and DNS are the same.  I have looked and looked for the configurations steps beyond setting up a VS that include  the IP configuration on the VM and the Host....  I know its here somewhere!!! please assist.

Dear friends;

I use Windows 10 pro and I have a vitual machine via Hyper-V.

As the regulary way , the way every videos explain, I've tried to connect my vitual pc to internet with switch manager.

But unfortunately, my vitual machine gives that eror " unidentified conenction" as a result of that I can not connect to the internet. How can I fix this problem.

We recently had a network traffic / virtual switch issue crop up, due to VMQ being enabled and improperly configured on Broadcom 10GbE adapters.  While that failure occurred, our backup appliances were taking backups of VMs.  Because of lost network connectivity, the Hyper-V checkpoints used for those backups remain on some of our VMs.

These checkpoints do not have the usual "Delete Checkpoint" / "Delete Checkpoint Subtree" options available to them.  How do I remove them so the virtual disks are merged and back to a single VHDX per virtual disk?

Hi,

I am trying to create a guest cluster using shared vhdx's as the means of storage.

But for some unknown reason I can't see my disks.

Although I can see them when I run a validation test. But it's telling me that the disk bus type does not support clustering.

Please see this screenshot.

Do you have any ideas?

Please can you help.

Thanks

Windows 10 Pro running Hyper-V, Windows 10 Pro  Virtual Switch up, network adaptor connected, now it wants proxy change settings to connect to internet, anyone knows what has to be done with settings and router, never used a proxy server directly.

I was "trying" Ethernet Realtech and Intel dual broadband adapter, restarted VM, a Kari tutorial said don't bridge anything to host OS, the switch will do it, invoking INTEL WI-FI adapter, its bridged, shared, and up in both instances.

The point is to get Windows 10 Pro Hyper-v VM connected to internet for windows updates and a application that can't run with Office 2013. 

The virtual switch was active, up, and I did not have network adapter selected to named new virtual switch, i restarted router, and VM a few times.  I need to know what proxy servers settings to use, I can see default gateway, and its own local IP.

Can anyone speak to proxy settings for a virtual switch and likely the adapter, the trouble shoot connections keeps coming back with change proxy settings.  It seems like I'm very close to getting this beast to work.  I've been fighting with it and reading and researching it for a couple days.

We tried merging a restored AVHD with VHD and it worked but the SQL was currupt.

We tried to try merge again on the Backedup VHD and the merge progress screen closes as such and then after give an error "invalid parameter " if we try merge again.  We noticed that the VHD file creation date is changing to current date.

Now we are looking to retrive sql data from AVHD, is there any utilities.

How to open an AVHD to access its contents?  I want to extract a file from it.

The AVHD I want to access is the most recent in a tree of snapshots for a VM.  I have deleted some of the snapshots in the tree, so the differencing chain is broken.  The VM will start, but its state reflects the original VHD, and I can't merge this AVHD back into the original VHD.

I tried using the Edit Disk Wizard to reconnect this AVHD to its parent, but got an error that the Wizard was passed an invalid parameter.

I also got an error when I tried to open this AVHD using WinImage.

Thanks.

Is there any 3rd party utility out there that can access a avhd regardless of the differencing chain?  Dont care how much it costs , badly need it.

I have a server 2012 host that just crashed, we were able to get the virtual hard drives for the servers that were on the host.

We built a new server/host running hyper-v manager.  Created new VM on the new host and used the same virtual harddrive from the previous host.  On the host, I only have one physical NIC, so I created a virtual switch in hyper-v manager (external) and it is running the host and the VM is pointed to it.  It should work

However, when I boot into the VM it takes 15-20 minutes at the please wait screen, another 10-15 minutes to logon and is sluggish, will not respond.  I boot into safe mode with network support and it logs in extremely fast.  I go into the network adapter settings, b/c I know it will not retain the IP address (static) from the previous build in the previous Host, and put the ip / gateway / subnet mask in as well as dns settings, reboot.  Same thing.

I boot back into safe mode, gateway is gone.  I try using the same IP address, it will not work.  I try putting a new, unused IP in, it then shows up with two IP addresses when I click on advanced.   I delete the old IP address out, leave just the new and it works..I can ping devices on my network and devices in other subnets.  I can surf the web, it works perfectly (in safe mode).  

I reboot, same thing.  Even when I go back into safe mode, the gateway is gone and the old IP address is in use.

I'm at a loss, i need this server going immediately. I've tried deleting and re-adding virtual switches with no luck.  There's something tieing up the ip/network on this card and i dont' know what. 

i've gone into device manager and shown hidden devices, the only thing I see that sticks out is there is a greyed out item called "RAS Async Adapter".  When I try to uninstall it, it verifies i want to remove and I click ok and it does not delete/does nothing.

I'm open to any suggestion/help.   This is a domain controller/VM for one of my elementary school sites, and I really do not wish to start over but that's my only next option.  

Any help is greatly appreciated, thank you!

Hi All,

I have a broad question about the Firewall behaviour on a Hyper-V Hyper Visor.

Does the state of the Hyper Visors Firewall affect the VMs running under it? For example if I have a VM and I enable SNMP traffic on that VMs Firewall will the traffic be allowed through without any alterations to the Hyper Visors Firewall? Or alternatively do I also need to enabled the SNMP Firewall rules on the Hyper Visor as well to ensure that SNMP traffic can get out?

Any help here will be greatly appreciated.

Kind Regards,

Davo

Hello,

I’ve build a 2012R2 Hyper-V cluster.  Each host has 6 10Gbps NICs.  I’ve created two teams,

• One team for Live Migration
• One team for Virtual machines with a vSwitch on top.
• The other two NICS are used for ISCSI A and B

On the team used for virtual machine traffic, I’ve created two parent OS vNics, one vNic for host management and another for cluster Comms\CSV traffic.

The cluster Comms vNic has been set with the lowest metric. 

Now, this is where I get confused.  I created a separate team for Live Migration so that this NIC team remains RSS capable and can therefore take advantage of SMB multichannel for fast live migrations.

However, I’ve been reading (here http://blogs.technet.com/b/cedward/archive/2013/11/06/windows-server-2012-smb-multichannel-and-csv-redirected-traffic-caveats.aspx) that CSVredirected traffic will use the NIC\team where SMB multichannel is capable. My concern is that is this only for CSV redirected traffic or also for CSV metadata operations?

So my main questions are:

Does CSV metadata and CSV redirected traffic follow the same rules? So in this case will CSV metadata traffic flow over the same team used by live migration, or will it use my cluster comms Nic that’s set with the lowest metric? 

Should I limit the amount of bandwidth used by Live Migration so that CSV redirected traffic isn’t starved when live migrations take place? (https://blog.workinghardinit.work/2013/09/03/preventing-live-migration-over-smb-starving-csv-traffic-in-windows-server-2012-r2-with-set-smbbandwidthlimit/)

Thanks loads in advance

Hi all,

a 2k12 R2 host with Hyper-V role, build on ASUS P9D WS, i5-4440 with iRST soft raid won't boot a Gen 2 2k12 R2 VM guest ("Boot Failed. EFI SCSI Device").
Even Gen 1 don't boot.

The guest was created by Disk2vhd v2.01 as vhdx on the same Hardware. After this the partitioning and formating was build up and created new by the default setup and installation of Server 2012 R2 as the new host with just the Hyper-V role.

So I have 2 questions:

How to get the guest vm boot?

Is there a licensing problem? As I understood a host with just the Hyper-V role is free or included on a Server 2012 R2 license.

Thanks for your help!

I have a VM whose status says "cannot connect to virtual machine", due to unreachable SMB storage on which it was hosted initially.

On trying to delete this VM using Remove-VM cmd,  I get this error.  But I could delete it manually in HyperV Manager console.  

Is any additional options, I need to add in Remove-VM cmd ?
