Hyper-V R3 and Datalink Layer

0
0

Running Windows 8 Pro (x64) With Hyper-V installed.
Trying to talk from a VM (Windows 7 Pro, x86) to some equipment using PN-DCP (Profinet Discovery and Configuration Protocol), ref
http://en.wikipedia.org/wiki/Discovery_and_Configuration_Protocol
http://wiki.wireshark.org/PROFINET/DCP

I cannot get this working. Using a physical machine with the same OS and the same Application running the PN-DCP everything is ok.
I suspect that non-IP protocols are not Hyper-V's best friends.

Does Hyper-V (R3 ?) on Windows 8 support these kind of protocols (Layer 2 ?).
If not, any workaround ?


Backing up HyperV Guests that have no Integration Tools

0

Hi, I am running a slightly older FreeBSD guest in HyperV. If I want to use Windows Server Backup to backup the server, will the backups of the FreeBSD VHD file be crash-consistent? Does the VM get paused while it is backed up? What is the best strategy to backup guests that have no integration tools installed, or are unable to be installed?

Thanks

Hi,

 I installed share point trail version previously, now i got new license key.So How can we activate new key through cmd prompt or Unattend mode wise.?

Thanks,

Kishore.

expanded the size of a VHD - didnt realize it had a snapshot - do not have a backup of the original vhd

Our exchange 2007 server runs in a VM.  It ran out of space today, so I shut it down, enlarged the disk and then attempted to reboot it.  It would not reboot.  Of course this is when I discovered that for some reason, somebody had done a snapshot back on 9/2.  I just called the outsourced IT group that manages our backups and it turns out that they have not been backing up the mail server, so I do NOT HAVE THE ORIGINAL VHD anywhere.

I'm sick to my stomach because everything I've read over the past several hours basically says there is no way to recover from this error without a copy of the original VHD.

Failover cluster yapısı için en uygun senaryo?

Merhaba,

Bir web servisi yayınlayacağız. Bu servisin veri tabanı çok önemli. Bu yüzden 2 node tan oluşan cluster yapısı kurmayı düşünüyoruz. Ama hangi senaryoyu uygularsak bizim için verimli olur karar veremedik. Donanım ve yazılım alt yapımız şöyle;

Server 2012 Datacenter(Hyper-v)

my motherboard is intel DH61DL, with the buildin network adapter 82579V (pro1000).

the hyper-v r2 cannot reconize the adapter. nomather I used the intel CD or the latest Driver from internet.

I've try win7 and win2008 r2, both can reconize .

Windows Server 2008 Hyper-V virtual network problems

0
0

Hello all,

I am renting a dedicated server running Windows Server 2008 R2 and I only have access through RDP at this moment. I have been trying to create a virtual network so I can set up a Ubuntu VM and connect it to the internet, but I have had no luck yet. There are 2 questions that I have:

1. In the dedicated server there is one Realtek gigabit NIC so I will have to use one card for both my OS and the virtual machines. When I try to create a virtual network and select 'External' and set it to work with the onboard NIC, my remote desktop can't connect to it anymore and I have to ask one of the technicians to remove it so I can RDP back into it. What am I doing wrong? Is there anything in the properties anywhere that I have to set up specifically?

2. Before I tried to fiddle with it there was already a virtual network present with the desired settings (external, using my NIC) that as a 'comment' has "Microsoft virtual switch", I did not set that one up as far as I know. I tried creating a VM and connecting it to this VNIC but it would not connect to the internet (no DHCP as far as I can tell). So I configured it manually by going into the VM (ubuntu 12.04 desktop) and putting in the gateway, netmask, ip and dns manually, using the assigned values by my datacenter provider. It said it was connected in Ubuntu, but I was unable to ping any domains or IPs. Any idea what could cause this? 

Thanks a lot in advance

Hyper-V DC Internet / LAN

Dear Folks,

I am desperately in need of help. This is the situation:

At the moment I am trying to create a DC at location. The company has a head DC but on other location. 

My 1st goal is to make an local DC at my current location with a DHCP and DNS. After I succeed with this then I need to connect the companies current phisical machines to the DC.

I've installed this Server with 2 NIC's: External "Internet" NIC(automatic DHCP from ISP: 192.168.178.1) and an "Internal only" NIC(with static IP) 192.168.179.1/24.

My 2nd goal now is to connect the current phisical machines to the static Internal NIC(192.168.179.1), so they automatically get IP-address from DHCP.
As you can see there are 2 differend subnets. To solve this i've configured NPAAS to route between Internet and Local NIC's.

Now the problem is thet I can't connect with the phisical PC's to the domain because it cant be found. When I assign the Phisical PC to automatically get IP from the 192.168.178.1 ISP(as mentioned above), I can Ping my Internal DC NIC 192.168.179.1. But shamely I still canno't join the domain controller and AD.

CAn anyone please help me out with this? I would really appreciate it. Thank you in advance



Are there any issues running 32 bit Server 2003 SP2 in Server 2012 Hyper-V

0
0

I've been having an issue with a Server 2003 SP2 32-bit VM I moved over from my old 2008 R2 Hyper-V farm recently.  It periodically BSODs and then reboots.  It was rock solid in the previous environment, so I am wondering if there are any documented issues with Server 2003 in Server 2012 HV.  

The previous environment was a Server 2008 R2 cluster comprised of three Dell R815s.  The current environment is also three Dell R815s in a cluster running Server 2012.  I used SCVMM 2012 SP1 to migrate the VM.

Also, after changing the RAM allocation down a bit from where it was (6GB to 4GB since the server wouldn't have used that much anyway), I now notice that the virtual NIC isn't connecting to anything.

Thanks,

-Russ

Manging Hyper V Centally

We have 5 nodes that are not being managed centrally. We have been advised that there is no budget to purchase SCVMM for central management so was wondering what the best options are. What has Microsoft got for small business like mine or are there any free tools that do the job from reputable software vendors such as Veeam or quest?

Limited Hyper V knowledge so please forgive me if there is an obvious answer

Hyper-V bin file consuming disk space.

Hi,
  
Host OS Configuration:- Windows 2008 Enterprise ,Hyper-V with KB950050 (64bit) update.
Host Hardware Configuration:- Xeon X7350@ 2.9 GHz x 4 CPU / 64 GB

I installed virtual servers on Hyper-V and found that everytime ".bin" file( with GUID) in snapshot folder ( default path is - C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines - this location can be changed using the snapshot location settings in Hyper-V settings) consuming disk space exactly same as memory configured for the guest OS in host system disk.It get disappeared when the guest OS became down.
we require to configure virtual servers with 20 GB RAM or more & found it requires additional disk same as RAM allocated in host system apart from the VHD allocating.

Does this mandatory ? i didnt find any MS article stating anything about it.
there is no snapshot created in hyper-v for virtual servers anyway.
Can we avoid this additional disk space requirement ?

Dynamic Memory shows wrong numbers and as such doesn't work...

Hello all,

I have quite a lot performance issues on a Hyper-V 2012 cluster. I have enabled Dynic Memory for my VM's, but I have the idea that it is not working, or maybe even contra-productive.

What I see is the following: When copying a large file from the network to a "local" disk of the VM (disk is running on an iSCSI volume attached to the hosts), the first couple of GB's are going fine. Then at once, the memory is filled up (the memory graph in the taskmgr increases liniar to almost 100% usage. The VM becomes very unresponsive and the copy slows down from 115 MB/s to some 100 KB/s.

This is where dynamic memory comes in: The amount of memory that I see in the host is the startup memory (in this case 6 GB). It does not increase, all though there is enough mem free on the host and the max memory is set to, well let's show all values:

PS C:\Users\superadmin> get-vm sp0002-003 | refresh-vm | ft Name,VMAddition,Memory,MemoryAssignedMB,DynamicMemoryBu

                                                    centage
----        ----------       ------ ----------- ----------- ----------- ----------- ----------- ----------- -----------
sp0002-0... 6.2.9200...        6144        3238         200        1133        True       40960        2048         OK 

So what I see is that the DynamicMemoryDemand is 1133. But in the VM, the memory usage is 98% of 6GB! 

Why is this not matching? Please help me troubleshoot this.

Regards,

Stephan van der Plas

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?

How to find the VMname with the DNS Name of this machine

0
0

Hi,

how can I figure out the VMname in the Hyper-V Manager (Not the Computername FQDN). The only information I have for this is the DNS Name, AD Computer Object and a powershell VMM 2012SP1 access.

Any ideas ?

Regards


Windows 8 Client Hyper-V: Hosted W2K8r2SP1 Server with both External & Internal vSwitch connections unable to access remote WMI of hosting windows 8 client - Access Denied Errors

0
0

Hi Folks,

Setup:

I've got a standalone windows 8 pc running client hyper-v.

Within the Hyper-V environment I've built a windows server 2008r2 sp1 standalone virtual machine.

The w2k8r2sp1 vm has both an internal and an external legacy network adapter connected.

I can ping the windows 8 host from the w2k8 vm.

It's also possible to ping the w2k8 vm from the windows 8 host.

I can remotely connect to WMI on the w2k8 vm from the Windows 8 Host using a local admin account for the w2k8 server.

Problem:

I can NOT remotely access WMI on the Host Windows 8 pc from the w2k8 server using a local admin account for the Windows 8 pc.



Already tried:

Disabling both firewalls has not made a difference.

I'm using a local windows 8 admin account with UAC disabled.

The following thread was also followed to no avail -

http://social.technet.microsoft.com/Forums/en-US/winserverManagement/thread/4f33837b-1cb1-4648-85b1-3ba87cbfe93e/

Questions:

  1. Is it possible to access a Client Hyper-V HOST systems' WMI Remotely from a HOSTED VM?
  2. Is there some special security flag that needs to be set at the vswitch level?
  3. Has anyone published an "Idiots Guides" (step-by-step) that I could obviously benefit from for configuring WMI Remote Access with Windows 8 and Hyper-V nodes?

All help is much appreciated.

Ultimately, I'm trying to manage the windows 8 client hyper-v host, create new vms, stop/start etc. from the hosted w2k8 vm.

Kind regards,

Graham.


Windows 2012 VM receive an installation warning message "Windows can not be installed to this disk"

0

   Hello to all. I have a Windows 2012 Std. working as Hyper-V host that currently holds just one guest, a Windows 2012 DC. I´m trying to install the second VM that will be a Windows 2012 Std. file server. I created all the virtual disks (.vhdx) on Hyper-V and tried several times to install the file server guest OS but I always receive the same message when arrive the "Where do you want to install Windows?" screen and select the Windows .vhdx to install Windows 2012: "Windows cannot be installed to this disk. This computer hardware may not support booting to this disk. Ensure that the disk´s controller is enabled in the computer´s BIOS menu" . I put the already created and reserverd for windows .vhdx on IDE controller and this problem always happens when there is at least one disk on the SCSI controller. The problem is that I have 4 .vhdx and one DVD drive, what will force me to have at least one .vhdx attached to "SCSI" controller and I don´t want to install Windows on another volume (other volumes are for data and backup and are large ones, 1,5 Tb, 2,5 Tb and 4 Tb).

   More information:

   1- The production DC has Windows installed on a .vhdx attached to IDE and has two other .vhdx disks attached to SCSI controller and I didn´t have any problem when setting it up.

   2- I tried a lot of things on this Windows 2012 file server: recreated the Windows (reserved for OS installation) file server .vhdx, moved it to another IDE controller on Hyper-V; deleted and recreated the guest OS; changed disks order to different channels and no results.

   Can you give me some help?

   Best regards, EEOC.

guest clock drift

0
0

Quick description so that people will not give me completely useless pointers like google has been doing.

1 - big hairy servers. 2008 r2 data centre, hyper-v with clustering, 5 active VMs per server with about 32gb each. Guests are all 2008 r2. 

2 - trouble has a 10g tomcat and is the only one drifting.

3 - There appears no way to tell the guest vm "you really REALLY want VM IC Time Synchronisation" like all the other VMs.

4 - NONE of these vms is a DC, that duty belongs to a completely separate machine. Repeat, the VM's are stand alone w2k8 r2, they areNOT in a domain.

5 - *EVERYONE* except this one VM is happy. Hosts getting time from the PDC, PDC getting it from NTP.

6 - Rebooting anything is an ABSOLUTE LAST RESORT. This is not the dark ages anymore.

7 - Integration stuff includes time stuff. Windows Time Service appears to be running as "delayed start"

8 - I don't need NTP accuracy, I just want VM IC Time Synchronisation to *work* 1~2 seconds is fine.

...

On this and only this vm, w32tm /query /source says

Local CMOS Clock.

The clock drifts back about 5 seconds in between 45 and 70 minutes. When first noticed, the windows time service was mysteriously "disabled" and this drifting started at 4am on a sunday when no one was playing with it. Before that it appears to have been in sync for some time.

CPU for this guest is all over the place, typically around 25% (the host registers a whole 1% cpu) the java process is quite busy brewing logfiles like there is no tomorrow. Possibly related to this, the terminal window's cmd.exe is horribly laggy. 

Experimentally restarting windows time has no effect, it is stuck on Local CMOS Clock,

The only interesting thing is that in the registry, there is no "IPC" under "VMICTimeProvider". I do not know where it went.

Q1 - what pokes it when it gets 5 seconds behind, how does it poke it.

Q2 - where did VM IC Time Synchronizaition Client go, why doesn't it come back?

So, any ideas, pointers or actually useful pages?

HyperV replication re-enable problem

0
0

Hello,

I have a problem about replication.

I already replicated exchange virtual machine to another Hyperv server. versin of two hyperv server is 2012 core edition.

When I checked replication status, I see replication isn't running.

 so, I removed replication from production server. After than, I try  to re-enable replication. However, isn't running again.

I get this error message;

 

and I see this log from event viewer ;

Hyper-V suspended replication for virtual machine 'Mars2' due to a non-recoverable failure. (Virtual Machine ID 4D84CB14-10B0-4B06-A0CC-2A709D8407FF). Resume replication after correcting the failure.

How can I re-enable replication ?or How can I research this problem ?

Hyper-V cluster - configuration failed

Hi all,

          We have a 10 node 2008 R2 cluster in prod and a 2 node cluster in the DMZ.

One VM guest in the DMZ cluster has recent;y started coming up with the following errors

The Virtual Machines configuration BB15D5EB-2966-47C2-9AEE-9B4E4FB569DF at 'C:\ClusterStorage\Volume1\DMZ11' is no longer accessible: The system cannot find the path specified. (0x80070003)

Cluster resource 'SCVMM DMZ11 Configuration' in clustered service or application 'SCVMM DMZ11 Resources' failed.

The configuration file (BB15D5EB-2966-47C2-9AEE-9B4E4FB569DF.xml) does exist, the VM is running fine.... but we cannot fail-over this one VM (the rest are fine).

Any suggestions apart from import/export? (which we will do as an option of last resort.... just at 500GB, the export/import will take the machine down for longer than we would like)

Guest NIC Speed and copy from host to guest

0
0

   Hello to all, I have a Windows 2012 host and started a copy today from the host to another VM that works as File Server that is also a Windows 2012. The rate is very slow, something around 10 Mbps, physical NICs are configured as auto sense and can reach 1 Gbps.

   Questions:

   1- Should I set a value (customer switch operates at 100 Mbps) on physical NICs, i.e. remove auto-sense and insert 100 Mbps for example?

    2- If I'm not wrong, a long time ago (virtual server or PC) one could quickly copy files from host to guest through special "extensions" on the guest, is it still possible? 

    Any special recommendations to increase NIC rate on guest OS?

    Best regards, EEOC.
