Server 2012: Enabling replication hangs

0
0

Hello All,

I have setup replication between 2 Hyper-V 2012 server clusters. When enabling the replication of a VM, everything looks fine. The Replica Server is found. All settings are correct and the replica server is reachable over the used tcp port.

When I click finish, I see a progress bar, stating "Enabling Replication..." which never disappears. Only when hitting Alt-F4, the bar disappears, but then I'll get back to the wizard.

It doesn't matter what setting a set for initial replication.

How can I troubleshoot this?

The operation on computer localhost failed

I did a hard reboot of my host machine when the VM was still running. Now I am not able to select my localhost from Hyper-V manager.

I am seeing this error - "The operation on computer localhost failed". I see all the HYper-V related services running on my machine and also have the .vhd of the VM. How do I restore my VM ?

DHCP/DNS on Internal Hyper-V network

0
0

Hi all,

Probably a relatively simple solution, but I've searched all over and can't quite find the answer I'm looking for.

I've got a Hyper-V host server running Server 2012 with several guests configured.  There are 3 NICs setup with Server 2012's NIC Teaming feature intended for use by the Hyper-V External network. There is a fourth NIC dedicated for use as a server management interface and not associated with Hyper-V.

I've setup a Hyper-V External network that uses the NIC Team. I've also setup an Internal network to allow the guests to communicate with the host and map drives from the file shares on the host without having to loopback through the host's management interface. 

Here's where I run into problems: I understand that DHCP is not available as a native feature of Hyper-V for internal networks and that each guest will receive a APIPA address by default. What I would like to achieve is to get DHCP and DNS working on the internal Hyper-V network (be it via the DHCP/DNS roles on the Server 2012 host, or another lightweight method) so I don't have to manually assign IP addresses to each guest, and then give this interface priority in the guests so they don't loopback through the host's management interface to access file shares stored on the host. They should also have External access but should never be accessing the host through the External interface.

I've tried setting up a DHCP role on the host and binding the Hyper-V Internal interface to it, but no DHCP addresses are assigned to the guests (they only end up getting APIPA addresses). What am I doing wrong, and is there a better way to go about this? Should I forget the idea of the Internal network altogether and instead team 2 NICs for Hyper-V and 2 NICs for the host's management interface to balance it out?

Thanks in advance for any input.


Virtual machine stuck in 'Left-Click-Down' state

0
0

So we have this very intermittent issue with our virtual machines.  By intermittent, I mean it occurs maybe once every 5,000 hours of virtual machine use.  However, we tend to see that every couple of days, so this comes up fairly often.

The user is connected to the virtual machine through an ActiveX RDP control.  At some point, the left-click button becomes 'stuck' in the down state.  When connecting directly to the virtual machine from the host, the mouse is still stuck.  The only way I've found to correct the issue is to reboot the virtual machine.  My first thought was that this was an issue with the integration services, but now I'm less sure.

Has anyone else seen this issue? If so, is there a workaround?  Is the problem fixed in 2012 with 2012 integration services?

Thanks,

Hi new to Hyper-V and Server 2012 - I have a test server but wanted to know the best way to utilize multiple NIC's

Current Setup (Dell PE1900 Server with 1 nic for connecting to VM's and 2 other for NIC Teaming)

Switch Independent - Hyper-V Port

Setup the two nic in a team called (Hyper Team) and in Hyper-V its using "Microsoft Network Adaptor Multiplex Driver" thought it should show/ use "Hyper Team"

create cluster vmm 2012 sp1

I can't seem to create a cluster.  When I try using the wizard, at the end I get an error that says "Network configuration of hosts to be clustered requires at least one static IP address to create a cluster.  Please specify at least one IP address and retry the operation.  ID 25342".  No where in the wizard is there a place to specify an IP.

The only place where this may be appropriate is teh "virtual switches" tab, which has nothing in it.

Both hosts have 2, 2gbit NICs attached to the same logical switch with a single virtual adapter with the management IP.

How can I create a cluster here?

Need help plz

Disk Layout Translation: Physical to Virtual?

0
0

Hi,
 
I have a physical server with Windows Server 2012 installed.  It has 10 fast 15K drives.  I need to have it configured for a SQL Server 2012 install. 

When installing SQL directly on a host OS, we take great care to separate IO types (random data read-write, random tempdb read-write, sequential log write, sequential backup write, etc) to different mirrors or arrays.  Our configuration considers performance and recovery. 

I'm considering Hyper-V.  I think it has some management/DR advantages even if I only have one VM hosted.  When I request a configuration, are the old disk-layout practices still valid?  Should I ask for a similar set of disk mirrors and arrays on to which to place fixed VHDs?  (Our server team will be doing the work.  If I don't say anything, I will end up with a single raid 5 or 10 with 10 disks.  This is not ideal for a non-virtual SQL system.)

Also, is it okay to use one mirror for both the host OS and the VHD used for the VM OS drive?  If not, then I lose 2 drives going virtual.  For example, for 5 mirrors:

Mirror 1: Host OS, VHD - OS
Mirror 2: VHD - SQL binaries, system database data files, system database log files, and error logs
Mirror 3: VHD - SQL user database log files and tempdb log files
Mirror 4: VHD - SQL user database data files
Mirror 5: VHD - SQL tempdb data files and database backup files

Thanks

Good morning,

we have a Hyper-V Server 2008 R2 with all updates.
A tandberg RDX USB-drive is connected.
The RDX is formatted with NTFS and use Bitlocker drive encryption.

We change the taps daily. After the change it isn't possible to access.
In the device manager the tap hasn't a file format.
Then I restart the Hyper-V Server 2008 R2 and the access is possible again.

Also I installed the official Microsoft hotfix:

Have a nice day and thank you for your help.

Win8 Hyper-V - VM getting internal IP when bridging with Wifi

I've followed all of the guides out there that say to create an Internal adapter for my VM, then bridge that adapter to my Wifi connection.  My host can access the internet, but my VM is getting an internal IP (169.x.x.x).  What am I missing?  This is the thread I followed...

Unable to run Virtual Switch Manager for a Hyper-v 2012 server

0
0

Hi,

I've had all sorts of issues with the virtual network management capabilities of Hyper-v Server 2012 (all, I suspect, due to my lack of understanding not with the technology itself).

After enabling "Allow management operating system to share this network adapter" I lost network connectivity on my server. In order to restore it I had to use "nvspscrub" and "netcfg" (per http://etechgoodness.wordpress.com/2011/08/02/virtual-networkswitch-troubleshooting/).

However, now when I run "Get-VMSwitch" on the server I get a "Generic Failure" error.

I also get the error "An error occurred while trying to retrieve a list of virtual switches" trying to use the Virtual Switch Manager.

Any ideas how to fix this?

Thanks

Hyper-V guest loses network connectivty

I have a server runing windows 2008 R2 SP1 with hyper-v role.  I have a windows 2008 R2 SP1 guest running that loses network connectivity.  I am getting this event message when the issue happens.  Event Id 7042

The TCP/IP NetBIOS Helper service was successfully sent a stop control.

The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]

I have disabled the power management option on the network adapter on the hyper-v server and rebooted but I am still getting network connectivity loss.  I have tried hotfixes that is supposed to fix the issue but the install says it is not for my computer.  Any suggestions on this would be helpful.

Thanks


Create a network bridge in Hyper-V

0

One of our clients has a windows 2003 TS. They plan to migrate it to a Hyper-V VM on Windows server 2012. They would like to test it be before the migration. We have converted it to the VM, but can’t activate it (we have only 3 days to do so) because the Windows 2003 and Windows 2012/VM are in the same network and same host name. Is there a way to setup VM to access the Internet without having host name conflict (current TS and VM host name are the same)? Perhaps, a bridge? But how?

How to create a 64-bit guest in Hyper-V on a 64-bit Windows Server 2008 R2 Ent?

0

Hello,

We have Hyper-V running on 64-bit Windows Server 2008 R2 Enterprise. How do I create a 64-bit guest in Hyper-V? I'm trying to install Windows 2008 R2 Std as a guest on this system, but the guest always ends up being 32-bit. I looked around and checked the docs and can't find any switch to determine if a new virtual machine will be 32 or 64 bit.


Consideration of consolidate several file servers to one VM acting as fileserver

0
0

Hi

I need some input and experience regarding this scenario we are heading against during the first half this year.

We have today a file server 2008 R2 and it is a VM running on a Hyper-v host (2008 r2)It has 3 partitions one c: (system partition) d: (home folders) e: (department data.) 3GB RAM

Is it 60 users that use the file server. And the amount of data is 350GB on the d: drive and 1,1 TB on the e: drive. The vhd`s are set to dynamically expanded (was going to set them to fixed but after an initial try the time it took to create them was extremly long so I was decided to go with dynamically). We are backing up the fileserver with DPM 2010 and from the agent installed on the hyper-v host once a day.

The  hyper-v host is a HP DL380 G5, 32GB RAM and 2 sata disk in a raid 1 with the parent partition and one raid 6 build on 6*500GB sata disks where all the VM running. It is running 5 VMs on the partition that is on the raid 6 disk array they are not any high load VMs except the fileserver that time to time write large amount of data to the disk.

Sometimes users complain that the performance of the file server is bad (that happens if several users copy data to the fileserver at the same time). I suspect that happen when data added to one of the vhd`s so it have to expand and the take all the disk IO and impacts the whole server. (and the other vms on the host)

We are heeding against a fileserver consolidation after we have acquired a new company with a 60 users and 1 TB data. So after that we are 120 users and 2,45 TB fileserver data and the growth rate of data is about 40 % every year.

I understand that we are need hyper-v windows 2012 to be able to have vhd larger than 2 TB.

So the plan is to buy new hardware to install hyper-v 2012 and export the current fileserver vm to that host and convert the vhd`s to vhdx. Then move the data from the oter filservers into the filserver VM.

My 3 questions are:

First have anyone experience about file servers that are running as VM`s that have a medium workload, and have vhd that are in the size off several TB`s? Was it working well or any problems?(I know that MS best practices is to use iscsi pass throw from the VM to  a physical disk area and not save the data on a VHD for large filservers)

How to size the underlying hardware? I have planned to have a hyper-v host with 6*3TB sata disks in a raid 10 to get better disk IO , then I hopefully can have some other vm`s running on the same disk array (and also parent partion).

Can dpm 2010 with an agent on a windows 2012 hyper host do hyper-v vm`s backup with single items restore as when running an dpm 2010 agent on a windows 2008r2 hyper-v host?

I hope I did not was writing to much now but if you read down to here, please reply if you have experience of this with large fileservers running as vm`s on vhd file(s)

Thanks

Jonas

NOw i made vm but when i am trying to start it i am getting this msg.

An Error occurred while attemption to start the

iSCSI target randomly gets dropped while doing backup (Hyper-v)

0
0

Hello here is our situation.

We bought a cloud-storage product, the company provided us an hyper-v (linux) VM.

The hyper-v mount the physical hard drive, and we use iSCSI Initiator to connect the VM ip.

I created a shared folder from that drive(mapped from iSCSI Initiator  )

The problem now is when we run the backup from another server, the speed will getting slower and slower, and when each file seems writting into the disk, the drive will be down from network(I can't access it from network at that time.)and the backup job will fail, but after a while the drive will be up again. (I can access it from local server, but not from the network when the problem happens)

I googled and found some people also have this issue:

http://www.experts-exchange.com/Microsoft/Applications/Virtual_Server/Q_23920391.html

https://www-secure.symantec.com/connect/forums/iscsi-target-randomly-gets-dropped-while-doing-incremental-backup

Now I am sure it's the problem from the 3 things : Hyper-v,  iSCSI Initiator, or the linux VM they provided to us.

Anyone has any idea? also I can't see any error from event logs, when the drive down from network.


Jason
