It depends! Does the client need VDI? Does the client want more powerful desktops than VDI can give them? There's nothing strictly wrong with this environment, though at this scale virtualizing the RDP server isn't getting them anything. Do they plan to scale up? If so, you can probably keep this and prepare to add more servers, virtual and physical. ...

Sounds like the DNS configuration is incorrect. If you only have 1 domain controller, set the DNS server on its network adapter to 127.0.0.1. If you're using more than one, set the primary DNS server to the IP of the other DNS/AD server, and the secondary to 127.0.0.1.

It sounds like you're running into IO contention. There are a couple ways of fixing it: Separating the workloads. Put the testing on one set of disks and the VMs on the other. That way one won't interfere with the other. Nuke the problem with SSD. Solid-state is much more I/O friendly. If you can afford the space you need, this will make sure your I/O ...

It's a balance between price and performance. Mechanical SATA drives obviously have better prices but are in no way designed for such jobs, so for a serious business it's a no-go SAS protocol has enhanced features (for example queue re-ordering) that allow them to better manage I/O from multiple VMs and so they are much-more efficient (even with the same ...

Is the virtual machine a domain controller? Have you tried below from http://www.veeam.com/kb1697 vssadmin list writers The results will appear as: Writer name: 'NTDS' Writer Id: {b2014c9e-8711-4c5c-a5a9-3cf384484757} Writer Instance Id: {ee24b741-eaf7-4663-8f95-b92ae8c5e164} State: [1] Stable Last error: No error If not listed as stable ...

Have you tried running precompact.exe or similar tool (easiest by mounting the ISO file) on the guest first to zero out the reclaimed space? Then run the VHD compact process after that. See Compact/Shrink an Expandable/Dynamic VHD to fully recover space

Make sure you create the VM on the node you're creating it from. I've seen if you are on NODE-A and attempt to create a VM on NODE-B, you'll get this error.

The saved state is corrupted, in Hyper-V manager select the vm and delete saved state. More details: https://support.microsoft.com/en-us/kb/2502233

EDIT @massimo already answered this (and I didn't realize he covered the attach-disk solution). But, since I already typed this up, I'll leave the answer here, since it contains a bit more detail about attaching a disk from a locked-out VM... To access your VM's disk if you're locked out, you can delete the Virtual Machine (but not delete the disk/vhd or ...

If you have installed the custom script extension, you may use it to disable or configure your firewall.

There is no way to run commands on an Azure VM from outside the VM itself; there also is no VM console access. This is a really big limit in Azure, unfortunately. If you accidentally lock yourself out of a VM, the only way to recover it is by downloading its virtual disk and running it on a local Hyper-V server, where you can get console access and fix ...

powershell is your rescue: $VM = Get-VMIntegrationService -VMName test-vm -Name Heartbeat if ($VM.PrimaryStatusDescription -ne "OK") { write-host "VM Dead ? restarting ..." Stop-VM test-vm -Force -TurnOff Start-VM test-vm } just add this to task scheduler. If You VM does not support heartbeat then modify this to ping the VM instead of ...

The problem is likely IIS running on the Virtual Machine. Did you: Reset IIS Check to make sure that the web server is configured to respond on port 57868? If you are not sure, try hitting http://10.0.0.199. If you have success, then check your port bindings

Answering my own question, because I stumbled across the answer the other day. What I was looking for was Consistent Device Naming. Apparently this problem is not specific to Windows devices. Consistent Network Device Naming is a convention for naming Ethernet adapters in Linux. It was created around 2009 to replace the old standard ethX which ...

You could always spin up a virtual firewall/router VM with two NICs, and route through to the VMs. PFSense plays nicely with hyper-v 2012r2+ and is incredibly easy to setup and manage.

On your Hyper-V host, install Routing and Remote Access. Then you can use RRAS to NAT from your public IP address inside to your virtual machines, using the IP addresses assigned to their virtual network adapters. However, beware! Installing RRAS from a remote session often locks you out as you configure RRAS as your session becomes invalid under the new ...

After over a year of waiting so as to prove the solution as valid, I'm finally able to post this answer. Dell's default BIOS settings have C-States enabled, which puts the computer in low-power mode during idle times. This is what causes the VMs to spiral into 100% CPU usage on a Hypervisor host (VMWare, Citrix included). The solution is to set the System ...

IIRC Hyper-V snapshots are supported in Windows Server 2012. In all cases, snapshots are equivalent to "restore from backup". So you should honor general rules of restoring AD from backup. The most important parameter is the TSL (Tombstone Life Time). I.e. restoring a snapshot older than TSL can cause a lot of troubles. It's better and easier to rebuild the ...

If you're using NLB on Hyper-V guests you need to enable MAC address spoofing in the Advanced Features of the vNIC on each guest.

Check the firewall (firewalld) on the F22 server and ensure that the ports are open. I would expect this to be part of the problem as by default these ports are unlikely to be opened. However, other things you may like to check Does routing need to be enable on the host and if so has it? Does the firewall on the host have to be opened and if so has it?
