Hi,
Is it possible to configure a virtual switch in private mode that allows VM's on separate nodes communicate? This was not possible on Server 2008 R2 and I was hoping that this had been fixed on Server 2012. I'm trying to avoid the use of VLAN's for was is basically private traffic between VM's spread across nodes in a cluster.
Cheers,
Matt

I have a brand new Dell PE R720 with 8 NICs (4 identified and NIC1-4 and 4 identified as dual NICs in Slots1-2)
All Drivers and Firmwares 100% updated and iDRac Enterprise, LifiCycle controller, etc.
Host with Win2012 and a VM WIn2008R2 with latest Integration Services enabled
At firts i saw a very slow data transfer operation, so i´ve installed the NT TCP testing Tool and the data transfer was terribly slow
I have 2 old R710 servers and a data transfer between then achieves 912 Mb/s
When i try to copy data to the Hyper-V Host using a crossover cable i could achive a 708 Mb/s, that´s OK for now.
If i try to use another cable connected in VLAN, using the a Cisco Swicth L3, ii can achive a max of 30 Mb/s, so i can assume that the cisco can slow down the speed, let´s trust in the crossover cable.
But...
When i create a VirtualSwitch using one of the cards connected to the virtual Switch (not using the crossover cable, but the cabling connected to the Cisco) the speed drops to 300 Kb/s... Believe-it! After turning off VM Queue on the Host machine properties the speed goes up to 5 Mb/s.. and now i´m stucked transfering data to and from Host and Guest with 5 Mb/s speed.
There is a lot of inconsistency in the fóruns, people solving the problem with a vaiety of solutions, sometimes updated drivers and firmwares, sometines changing TCP parameters and so on. There´s no patterns, a lot of solutions to the same problem.
I´m confused, because some parameter can exist in Host, in Guest and sometimes in both!
Wich is the best practice?

I want to write a VM management website to let our customers control their VMs.
I hope our customers can connect to the console session of their VMs by by themselves.

This thread says we can use Hyper-V RDP ActiveX control to implement this easily,and there is a sample on the ddc homepage.But I can not find the Hyper-V RDP ActiveX control file and the sample code.
Can anyone tell me where can I download them?
Hello ,

I am just wondering if it is possible to edit the OS disk without downtime in Hyper V 2012.
This is possible in VMware but it appears that you cannot in HV. Why can a competitor product do this but Microsoft's own cannot for a Windows guest?
Hii... all..
I am using windows server 2012 with hyper-v too. I have installed 4 Virtual machines in hyper-v.
The host machine is having the internet connection and NIC attached as we can understand. Now, in all the VM's, I have created two network adapters in which Virtual switch which is already created by me in the host machine is defined. Now, the issue is that the internal switch defined there is working nicely and communication is possible whereas the external switch defined with another network adapter is not working and as per the configuration the VIRTUAL EXTERNAL SWITCH can be used for internet connection only. Finally the main issue is that I can not access internet from the virtual machines.
Please help me out..

I have a dell server which is running with windows 2008 server. I have enabled hyper v and dhcp roles on it. This server has a static ip in a private network.
I have four hyper v guests which are running windows 7, however, it could not get dhcp from the host OS.
I have searched the internet and it seems that it is only possible to have dhcp on the host OS with two NICs. Is it true? Does all NICs need to have static ip associated with it?
I'm not sure if this would be a better suited question for the plain old Server 2012 forums, so feel free to move this topic moderators.
Quick back story on our infrastructure. We have been building our own servers for the past couple of years to serve as a private cloud foundation using SCVMM 2012 so that our engineers can build out and deploy VMs as needed without having to ask IT to do this for them. This has been working great up until recently when I decided to use Server 2012 after the recent release of SCVMM SP1 instead of 2008 R2 on our latest build.
All 4 machines are identical other than operating system, 3 of which are using 2008 R2 Enterprise and the most recent 2012 Standard. 2 of these boxes are running 4x2TB locally in a RAID10, one of them is using the Microsoft iSCSI initiator to a Microsoft iSCSI Target we setup that has a 8TB LUN and the latest Server 2012 is also using the iSCSI initiator storage to house VHDs and VM config files.
The Server 2008 R2 box currently has 24 VMs running with the iSCSI disk reporting a highest active time of 30%. The VMs work seamlessly and I've had no complaints.
The Server 2012 box currently has 12 VMs running with the iSCSI disk jumping between a highest active time of 10% and 100% and of course when it spikes to 100% the VMs become incredibly slow and sometimes completely non-responsive. Of course I'm getting complaints
left and right.
The NIC configuration on the hosts are identical since the motherboards are the same the NICs are the same. I'm trying to figure out why the IO is so terrible in 2012 but works fine in 2008 R2.
Goodday Folks,
I have a brand new windows server 2012 Server. I setup a VM w/ win2k8r2.
for whatever reason, I cannot RDP into the VM. I'd like to gain access from other PC's inside the domain, as well as from remote locations. I can ping the virtual internal network adapter, but cannot RDP into it from within the network. I cannot ping the external virtual adapter(from within or outside of the LAN), but can RDP into the physical external adapter(both both within and outside the LAN).
Is there anything im missing?
Please advise,
thanks in advance

can anyone please tell how multiple administrators can manage SCVMM remotely??? Since RDP is not feasible.
Thanks in advance
Can anyone please tell how to deploy or create ova files in hyperv i.e SCVMM or Hyperv manager??
Thanks in advance
Hey,
I'm trying to install Hyper-V on a new machine (HP Elite 8300) and getting an error: Use RAM the provides error correction, I can't seem to find this specifc in the Windows server Catalog.
I'll try to upgrade the bios - but before doing so, is there any way I cant tell this server is qualified for Hyper-V?
I wan to install websitepanel with server2008r2 sp1 whith hyper-v to manage my server from any where is it possible
Please provide me links ir steps i have read documents ut after doming that its giving me error

hello everyone,
I know it's an old problem and based on all the posts I found on the forum, it doesn't seem to be easy to be resolved.
the situation is that we run software on virtual servers and this software is a single thread type of application. it would run a single process on a single vCPU and maxis out, and as of now the developers of the application don't have any plans to make the software take advantage of all of the available CPUs.
I tried with the weight and relativity but it does not seem to help. so I thought to myself, what if there's a software out there that you can install on the VM and it would actually create a single virtual CPU that runs on top of all the available CPUs, so that when an application with a single thread like that one I am dealing with uses this virtual CPU, it would actually be using all the available CPUs without even knowing.
it might sound like a crazy thought I know but I already found some free ones that could actually do that, such as:
http://sourceforge.net/projects/unen/
http://sourceforge.net/projects/vcpu-64bit/
however the company I work for would not allow shareware or any free software for security reasons, so I am looking for something similar that's not free and comes with support and what have you.
any ideas?
any help or comments are much appreciated.

Good morning all,
we have a web server that hosts lots of web applications that I create with a batch file script using appcmd.exe. the idea here is that each team has their own web app and they must not be able to access the other's web apps.
I am able to secure them with Authorization Rules, which by defuault is set to inherit and allow access to all, but I would like to be able to secure them with appcmd.exe so that I can add a line for that in the same batch file.
I am not being lazy, but I am trying to make sure that I don't forget to secure them and then fail audit or security scan.
any ideas?
I appreciate all comments and assistance with this matter.
Thanks

I am setting up a couple of servers that have 4 10G adaptors in them, 2 are for ISCSI storage and the other 2 are for network traffic. I have them currently teamed using the teaming software in server 2012. When I try to create the switch in hyper-v it gives me an error saying the adaptor is part of a team...
I only have the 2 adaptors available, do I need to break the team and assign 2 IP addresses to them and then create the hyper-v v-switch? I am not concerned with using multiple vlans. All the servers were going to be a part of the same vlan as the hosts.
Thank you
