Hyper-V Manager not able to connect the Local Server
Dear Experts...
Greetings !!!
1. Issue Description:
Hyper-V Manager not able to connect the Local Server – Shows connecting to Virtual Machine Manager Service state and did not connect. Hyper-V Host shows Host Not Responding in the SCVMM console
Due to which VDIs were not launching to newly connecting users as just disappearing
2. Temporary Fix:
If we restart the server, the issue will be resolved but the current active users gets impacted.
Need to power on all the VDIs and ensured all got registered state
And also the same issue keep on re-occurring frequently and affecting production users
3. Troubleshooting Steps Taken:
We tried to restart the service SCVMM and WS-Remote Management service which got restarted. But still the issue persists.
When we restart the WMI Service, one of its dependent service Hyper-V Virtual Machine Manager (vmms.exe) goes to stopping state and neither stopped nor restarted.
Tried to kill the vmms.exe process from task manager and via command prompt using the commands but it never destroyed.
It says cannot stop the Virtual machine manager service, already another running instance exists, access denied (when kills process from task manager), etc.
Until the server reboot the issue will not be resolved.
Thanks in Advance ...

My Virtual Machie File server is very Slow when a Copie are file with storage in cluster Hyper V
Good afternoon!
, I made a Cluster with Hyper v - Failover Cluster, with two Nodes and 16 Roles and create the Storage with 3 disks (Qourum of 1GB, and two distributions of 5TB and another one of 4TB), and it works perfectly. one of the Roles in this case the virtual machine with the file server configured and allocated the 4TB Disk.
In this Cluster I have a Database Application running very well
To make the Cluster I am using two HP Prolaint DL360 G8 servers, each with 136GB Ram with 12 CPUs for each with 2.5 GHz,
When copied a file from Virtual machine (FServ) to the server in clustter it has good perfomence of transference 80MB / s or more.
The problem starts when I try to copy a file from my file server to my PC or make storage on it, it takes a speed of 300kbs / s

Requirements for using Hyper-V
Hello,
I'm new to Hyper-V. I have a .vhdx file which is pretty big 360 GB. I to run it as virtual machine. I tried to convert it to other virtual disk image formats in order to open it in other virtualisation tools, but I could not boot the vm from the converted image files. It seems that I could directly boot a vm from the .vhdx file. I tried few tutorials to boot enable Hyper-V on my machine but I cannot see Hyper-V Manager if look for it in start-up search. What are the requirements to run Hyper-V. I have Windows 10 64-bit Enterprise running on my laptop. Also is it possible to such a big image to .vdi or .vmdk formats?
Thanks.

apply vs revert
revert and delete checkpoint are absolutely clear...
basically I can quickly test if my thinking about APPLY is correct:
revert will bring a VM to the state after a checkpoint was taking, removing all changes made after.
I understand that Apply save(apply) any changes made after checkpoint creation and it will not be reversible.
Correct?
Then if Delete checkpoint will be made this checkpoint (with Apply) will be merged to VM.

what are hrl.tmp files and can I delete them?
I have a replica server that has many files with the extension hrl.tmp. These files exist in three groups based on different dates. One group of hrl.tmp files is from august of 2017, another from January of 2018 and the last from February of 2018. The files are taking up around 1 TB worth of space.
Replication health on the server is normal and replication is occurring every 5 minutes.
What are the hrl.tmp files and can I delete them to recover the disk space?

Windows Server 2019 Hyper-V Guest on Windows Server 2019 Hyper-V Host
Hi,
Short version: Hyper-V role installed on Windows 2019 with gen2 Win 2019 VM. File share created on that Win 2019 VM. File open (200Mb) or copy from share with Win 10 client machine is realy slow.
Please check detailed issue description: https://social.msdn.microsoft.com/Forums/en-US/3248a691-d32f-4ac6-9175-94524afc35ba/windows-server-2019-hyperv-guest-on-windows-server-2019-hyperv-host-networking-performance-error?forum=servervirtualization .

Setting network configuration on Hyper-V Linux Guest VM using WMI - SetGuestNetworkAdapterConfiguration
Hi,
I am trying to set network configuration like IP address, DNS, Gateway, address policy (dhcp/static), etc. on the Hyper-V Linux guest VMs using SetGuestNetworkAdapterConfiguration API in WMI through powershell. I need some information on this API.
1. Sometimes, the call is returning asynchronously and sometimes the operation is done synchronously. Why is this happening when the parameters are the same?
2. When call is returning asynchronously, when retrieving the job object from the return variable is resulting in following error:
$ret = $Service.SetGuestNetworkAdapterConfiguration($vm, $networkSettings[0].GetText(1))
$jobInstance = [WMI]$ret.job
Cannot convert value "\\HYPER-VHOST6\root\virtualization\v2:Msvm_ConcreteJob.InstanceID="8273DB55-AF16-4264-912C-FBF321AA1664"" to type "System.Management.ManagementObject". Error: "The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)"
Am I missing something here?
3. Is there any limitation using this WMI API for setting network configuration on Linux guest VMs, since I am running into these issue intermittently in Linux VMs?
I would appreciate any pointers for these queries.
Thanks,
Priya

VM Multiple Checkpoints Created with no Corresponding avhdx files
Dear All,
Thank you in advance if are able to help me solve a problem.
I am a total newbee regarding VMs but I am stuck to solve this.
We have a physical machine Windows Server 2016 based which host 2 VMs and 1 is no longer working properly.
After a lack of disk space a local back-up crashed.
Hyper-V apparently have created multiple check-points.
The treeview of my VM shows, 2 Levels with Blue Icon and 4 subsequent non-blue, sorry for the non technical description ;-)
I have only 3 files, 1 .vhdx and 2 .avhdx.
I can set the VM to point to my vhdx file and the inspection goes well.
I have reconnected the avhdx from earliest to latest using both Hyper-V Manager and PowerShell (ignoring Id Mismatch).
Get-VHD command says correct parent-child relationships but says files are not attached.
I can start the VM but it is in initial state without data contained in the checkpoints.
I have tried to delete some checkpoints but with no success.
It's been 2 days and I am running out of ideas, any help would really be much much appreciated.
Warm regards,
Thomas

Hyper-V Server 2019 - RDP not working
Hi,
So I am testing with Hyper-V Server 2019, which I deployed to three brand new HP Proliant gen10 machines. I'll test on them for a while before putting them in production. Installation was a breeze, as with Hyper-V 2016. However, I can't seem to enable RDP on Hyper-V Server 2019. When I enable through the menu, it says it's done so, but alas, netstat -a reveals there isn't even a process listenening on port 3389.
I checked the registry, HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server is correct. The required services are running. Firewall is completely disabled through netsh for testing. Remote administration is working fine, RDP is not listening at all.
Anyone else ran into this?

Hyper-V VLAN on External Nic
Hello
I have Hyper-V 2016 installed with PFSense and I created a LAN with 192.168.1.1 range and a VLAn with 192.168.20.1 range and tag of 30. Both of the ranges have DHCP enabled. I'm also have a un-managed switch installed on the LAN port with a Unify AP router. Any device connected to the switch is able to get an IP address from the 192.168.1.1 however when I trunk the LAN adapter using "-VMNetworkAdapterVlan" I'm not able to get an ip address from both 192.168.1.1 and 192.168.20.1. I'm I able to use a standard LAN and VLAN on the same NIC adpater?
Thanks for the help in advance

Are all Hyper-V VM connections done through some type of RDP?
I have a Hyper-V VM setup on my desktop system. This VM is running a Shared PC setup and it is configured to not allow remote connections. I thought this wouldn't be an issue since I am trying to access it directly via the host machine, not through any sort of RDP client, however whenever I try to login it always says that Remote Desktop connections are not permitted.
Does this mean that even when connecting to a VM hosted on the same machine, that the connection is still technically running through some type of RDP?
