Hi,

Have a question related to containers: let's imaging we have enterprise infrastructure based on MS Applications like Exchange (all roles, 10 servers), Skype for Business (all roles), 20 MS SQL servers, SCSM (4 server config), SCOM (4 server config), 10 AD server, 10 file servers, 10 nodes of the Terminal Server, 10 other Application servers based on Windows Server with 3'rd party applications and other. All these located in virtual environment. Is it possible to use containers to save resources and reduce maintenance?

Thank you

GoodDay,

I need some assistance with a configuration.  For simplicity sake I may refer to hardware with incorrect terms in order to clarify host verses client.  I have done some thorough searching for what I wish to do to no avail. I cant imagine this not being a unique setup.

In simplest terms I have diskless server blades.  I wish to boot them directly from my VM's located on my SAN's Box.

• I have plenty of gigabit nic cards, cable, etc...
• Assuming the need to use the iSCSI  virtual disk in server manager?  However, I cant get my head around the setup required.
• Need to use the diskless blade resources, CPU/Memory for the VM's running from the SAN's Box.

It looks as though that with a fiber backbone that this is a common setup.  However it appears that gigabit Ethernet is not an option?

I have found that the latest version of the Dell MD Storage has ODX on by default. When using the storage migration with this turned on the VHDX files transfer instantly between the LUN's but the VHDX is corrupt and causes the Virtual Server to blue screen and then to never boot again.  I have yet to find a way to recover any data. 

My current work around is to disable ODX on the array itself which means that the data is transferred by the hosts, but does not corrupt the VHDX files.

show storageArray odxsetting;

set storageArray odxEnabled=false;

Is it possible to have two VMs on different hosts communicate on crossover cable?

I have two hosts with two physical NICs, one connected to external production switch and other is connected via Crossover cable with each other. I have external virtual switch created which allows both hosts to communcate with each other as well as VMs on each host to ping both hosts.

Host1: Crossover cable External vSwitch (10.0.0.14)
VM1: connected to External vSwitch (10.10.2.14)

Host2: Crossover cable External vSwitch (10.0.015)
VM2: connected to External vSwitch (10.10.2.15)

ping host1 from VM1 -- success, ping host1 from VM2 -- success
ping host2 from VM1 -- success, ping host2 from VM2 -- success
ping VM2 from VM1 -- failure, ping VM1 from VM2 -- failure

Any suggestions are greatly appreciated!!!
Thanks,

We have a 2012 R2 Server Standard VM running on Hyper-V 2008R2 Host for few months, then we migrated the 2012R2 VM to Hyper-V 2012R2 Host. Since then, the VM crashes twice a day with BSOD and no specific crash message.

The Hyper-V Host is running fine, and other instances (none is 2012) runs fine on it including some Linux based ones. The Hardware is latest Intel Xeon E2600 v3 with 32GB DDR4 RAM.On the old Hyper-V 2008R2 Host, everything was working perfectly fine.

The VM is 2012R2 Standard with 5160MB RAM assigned and 4 Virtual Processors.

What we have tried so far:

- Remove Device Manager devices, and allow windows to reinstall them

- Integration Tools says it is up to date

- Removed NIC and let windows reinstall, reinserted the IPs

- Ran chkdsk C: /R (it didn't do anything)

- Ran rootkit/virus scan, checked nothing suspicious in DriverView (all MSFT drivers loaded)

- Checked the BSOD dumps using Bluescreen View and WindDBG , the results are inconclusive (below):

- Performed memory diagnostic scan on the VM, no issues

- Ran Verifier, there was no drivers loaded other than MSFT drivers. Also checked Sigverif , and found no issues. Also updated mc_updateGenuineIntel.dll with updated Intel micro code update.

- The problem was happening with the disk in VHD format, so we converted it to VHDX but the error persisted. There were no errors while converting and have not seen anything indicating an issue with the VM (nothing missing, nothing corrupted). The VM runs MSSQL 2012 DB.

- All Important, Critical and Optional Updates installed

- The old Host 2008R2 had NTFS partition, the new Host has ReFS partition

- The errors are:

Hello all

Have just setup Hyper-V on a standalone server and I want to iron out all the wrinkles before it goes into production. I have noticed an 16945 event in the system log (MAC conflict: A port on the virtual switch has the same MAC as one of the underlying team members on Team Nic Microsoft Network Adapter Multiplexor Driver).  Checking this out lead me to http://social.technet.microsoft.com/wiki/contents/articles/31357.hyper-v-mac-address-conflict-event-16945.aspx.

In the article the screenshot shows 3 identical MAC Addresses for a physical NIC, the NIC Team and the Management adapter (exactly what I have).  I also notice in the article that the author only changes the MAC Address on on the NIC Team (Microsoft Network Adapter Multiplexor Driver), leaving the Physical NIC and the Management adapter with the same MAC Address.

Is this correct? I would have thought that you would need to also change one of the other 2 (Management adapter?) MAC addresses as well.

Cheers
Tony

Hello, I am looking to setup a 2 node Hyper-V cluster, each with it's own local storage for OS boot. For the virtual machines, I am looking to use a Netgear NAS product, RN51600-100NAS, however I am not sure whether this will work or not. 

So two questions, 

1. Will this work?

2. Will this build be supported by Microsoft?

Dear Hyper V Expert,

May I know whether is it possible for 2 Virtual Private Switches in to communicate to each other? I am trying to simulate the environment whereby HQ is connecting to remote sites, so I will be assigning 2 different subnets and to check the replications whether can work. The reason why I am using private switch is because I am trying to avoid the communication from the test environment to accidentally access the production environment. So, I think the safest is to use virtual private switches and connect those VMs to those switches.

Please help to advise.

Thanks.

Regards,

H

Hello!

I have Intel Server R2308GZ4GC. I've installed Windows server 2012 R2 Standard with Hyper-V role. Recently I've installed 2nd Intel Xeon E5-2630. But host windows still detects 1 CPU/6 cores/12 logical processors only.

I tried to remove Hyper-V role - windows detected 2 cpu/12 cores/24 logical processors. After I installed Hyper-V role windows began to detect 1 CPU again.

I couldn't find out answer why is this happening?

As I understand it the "Move Virtual Machine Storage" screen is supposed to enumerate the CSVs available to the cluster in the bottom left portion of the window.  It seems to be stuck on a "Loading..." status and never shows the CSVs.  Also, when I try the "Add Share" button and type in a share to use it doesn't do anything.  Thoughts?

Hello,

    If I was to have three hosts with say (5) physical drives attached to each host to be used as storage volumes. 

Host1:  Drive (F,G,H,I,J)

Host2:  Drive (F,G,H,I,J)

Host3:  Drive (F,G,H,I,J)

Is there a way to provision/limit the storage individually on each drive so say I wanted to reserve 100GB on each drive so it never hit its max capacity.  So Drive F,G,H,I and J can use all of the storage except until it hit that 100GB threshold or a predefined limit.  Can this be done within VMM or is there a way to set this up?  I appreciate any help and apologize for my newcomings.

Thank you,

-Bill Q

All,

Am fairly new to this technology. So please pardon me if there is something silly question i have asked.

I have Server 2012 R2 as my host OS where i have enabled the Hyper-v role. I have only one NIC card on my host OS. I created a new VM of Server 2012 as guest.  I have created a Internal Virtual Switch and provided an IP address as 192.168.100.101 and a default subnet mask and no gateway IP address. On my Host OS I can see a new ethernet and have configured the IP as 192.168.100.100. 

I am able to share the folder from the host and the guest. But cannot access the internet from the guest. I tried enabling the internet connection sharing (ICS) on the host Physical NIC, but it gives me warning that "LAN adapter will set to use IP address 192.168.137.1"

So how can I enabled the internet and also sharing from the guest ? Please advise.

Hi,

had to perform some job on Hyper-V host (2008 R2) of Remote Site.

When logged in found a weird time issue.

Two VMs (2008R2) running on Host: one is DC and other Print Server.

DC shows correct time, while Host and second VM (print server) are 10 min ahead.

1. Time sync is unchecked in both VMs settings

2. Logon server for the Host and second VM (showing wrong time) is DC (running on the same host).

3. All three are on the same Site and subnet.

What is wrong?

Thanks.
