How to boot vm in order to reset Administrator password

Hello guys,

I want to reset Administrator password. I tried to boot, but I even couldn't boot.

Server OS: Windows Server 2012 R2 I have a VM Generation 2.   I set "Boot from DVD Drive" in Firmware category in Hyper V setting and tried to uncheck Enable Secure Boot, but the Windows Setup menu didn't show up.

I referred to the following sites:(Sorry I cannot contain any links...)

Hyper-V VM Generation 2 - How to boot from .ISO

Resetting Administrator Password in Windows 2012

Actually, I tried similar things by making a similar situation in my windows10 at home and I could boot and reset a password, so I don't know what I'm missing for the windows10 in the office. 

I would appreciate any advice. 

Thanks in advance.

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 ...

Hyper-V 2016 VMs stuck 'Creating checkpoint 9%' while starting backups

We have a two clustered W2016 Hyper-V hosts, every couple of days one of the hosts gets stuck when the backup kicks off. In Hyper-V manager the VMs all say 'Creating checkpoint 9%' It's always the same percentage 9%. You can't cancel the operation and the VMMS service refuses to stop, the only way to get out of the mess is to shutdown the VMs, and hard reset the effected node. The backup works for a few days then it all starts again.

The only events I can see on the effected node is:

Event ID: 19060 source: Hyper-V-VMMS

'VMName' failed to perform the 'Creating Checkpoint' operation. The virtual machine is currently performing the following operation: 'Creating Checkpoint'.

Can anybody help please? Cluster validation is clean. Hosts and guests are patched up.

Using Teamed NIC with Hyper V, and a WS2016 VM

February 21, 2019, 4:38 am

I have a server running Hyper V 2016, which manages a WS2016 VM . The server has dual ethernet NIC's which I was looking at teaming up to improve ethernet performance on the vm. I followed the procedure in this article 

https://docs.microsoft.com/en-us/windows-server/networking/technologies/nic-teaming/create-a-new-nic-team-on-a-host-computer-or-vm

The procedure worked fine for Step 1, items 1-18.

In Step 2 where you set up the NIC team in Item 2, I see the two virtual switches setup in Step 1 (not the two ethernet nics) I try to add these to a team but I see an invalid parameter error.

I checked on this message, and this was caused by trying to team the ethernet adaptors which had already been associated with a virtual switch, which cannot be done. 

This implies the procedure shown in the article is incorrect.

What is the correct way to set this up ?

Thanks

Tony

Copy text from Guest to Host

I am using Windows 8 Pro (with Hyper-V Role) and have created a Guest Virtual Machine for Windows 2012. 

I am surprised to see that the Guest Virtual Machine Connection only has one way to send Clipboard text.  Wish the Clipboard menu was complete to support copy/paste both ways.

How does one transfer clipboard text from guest to Host.  Please note that I have not setup networking on my Guest.

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?

How to monitor performance for a specific VM in Hyper-V

Hi guys, 

I have two Hyper-V hosts bundled in a failover cluster.

The storage for virtual machines files is a fiber channel SAN.

There is a tenant on that cluster that who complains about server performance.

I increased the amount of memory now I can see that memory demand (memory pressure) is lower than the assigned amount of RAM. 

However, I'm still getting complaints from that tenants regarding performance.

Below are CPU and memory configurations. 

Is it possible to monitor a specific VM?

Thank you.

Hyper-V more than 8 NIC for VM

Hello,

I have Hyper-V host machine connected to the switch with trunk port. There is VM with Windows Server 2012r2 and it's Domain Controller with DHCP and DNS role.

There are 12 VLANs in our company. I added 8 NICs to the VM and configured 8 vlans on them just by configuring ip for each NIC in WS 2012r2 and everything works as expected. Then I reached dead end and there is no way to add more NICs to the VM...

I tried to delete all unnecessary NICs and leave only one and change it to work as trunk with powershell command: 

Set-VMNetworkAdapterVlan -Trunk -AllowedVlanIdList 1-10 -NativeVlanId 100

but I don't know what to do after that - how to add virtual NICs inside VM to handle VLANs.

Also, there is no option to provide VLAN ID in device manager in VM. Probably Hyper-V NIC driver doesn't support it.

What I'm trying to do is to configure VM-DC to work as DHCP for 12 VLANs. I googled for 3 hours and I didn't find any solution for similar scenario, maybe my questions to google was bad ;) Can anyone be so kind and help me?

Thanks in advance!

Hyper-V Virtual Switch Causing 20% Usage Of CPU For System Interrupts

February 10, 2019, 2:25 am

Every time I create a virtual switch in Hyper-V it causes a 20% increase in CPU from System Interrupts. I know it is the virtual switch because I have tried it a few times now and every time I create the new virtual switch then I get the above problem.

I have windows 10 pro, which is kept updated on a regular basis. I just follow the normal (default) steps to create the virtual switch:

  1. click on virtual switch manager, create virtual switch(external)
  2. add a name to the virtual switch
  3. External network checked with my laptops Qualcomm Atheros AR9485WB-EG Wireless Network Adapter, Allow management operating system to share this network adapter, checked.
  4. Then I click apply.
  5. Then in the virtual machine I go to settings and make sure it is using this virtual switch.

I would be extremely grateful if someone would be so kind as to help me figure out how to resolve the problem of this causing  a 20% increase in CPU from System Interrupts.

Windows Server 2019 Datacenter boot loops after enabling Hyper-V

I took my Windows Server 2016 Datacenter test server in my home lab (Dell R710 with two X5650s and 32GB of RAM) and installed Server 2019 Datacenter on it to try out the new features that are centered around VMs (Hyper-V) and data deduplication. The OS install went fine, but after enabling Hyper-V in Server Manager, the system goes through its normal reboot that occurs during Hyper-V enablement, then it proceeds to boot loop. Windows Server 2019 install media's boot repair does not fix the issue, and I cannot get in via Safe Mode. Any advice would be greatly appreciated.

HyperV Cluster Replica Broker error - "object could not be found" from Enable-VMReplication Powershell

November 18, 2016, 11:18 am

Ok I admit it. This one is driving me crazy ;)

1) I have two Server2016 (Standard) HyperV Clusters - Source01 and DR01. Both part of same forest/domain.

2) Both Source01 and DR01 clusters have a HyperV Replica Broker installed and replication settings configured for Kerberos, Port80 and allow from any server.

3) I can initiate VM Replica successfully in both directions using the FailoverClusterManager UI. It creates the replica, transfers the initial data and everything appears to work.

However....

I need to create the replica using Powershell, but when I try to do it using the Enable-VMReplication powershell command it fails with:

I must be doing something wrong as the UI works. Perhaps some remote permissions not enabled? Remote WMI? something? hopefully some rookie mistake...

1) I've turned the firewall of DR01 off (just in case, just until figure out this issue)

2) The hyperV virtual machine management service is running correctly on both Source01 and DR01

3) the HyperV console on Source01 can correctly connect to DR01 and view/manage the VMs in the console - and vice versa.

Anyone got any ideas? Or seen this behaviour before?

thanks

Joe.

hi there i would like to connect iscsi volume to one of my guest vms

my question is about the networking.....

my iscsi is on vlan 10 and my normal vm traffic on vlan 1

i have dedicated iscsi nics on my hyper-v hosts (using 10 GIG)

my vm traffic is on 2 x 1 G NICs (teamed) . but only 1G. 

Do i create a new virtual switch or just trunk the existing virtual switch even tho its 1G ?

I don't see anyway to create a new virtual switch and utilize my 10G iscsi interfaces

When i delete a checkpoint, virtual server crashed and also the host crashed

Hello

I have a server 2012 R2 host with hyper-v.

In the hyper-v i have 1 virtual machine that is 1.6 TB in a SSD disk of 2TB (1.81 TB) which left me with 168GB available.

i did checkpoint to the virtual machine, and the checkpoint growth a lot. So from 168 GB free space, it turned to 40 GB free space. i then  , wanted to remove the checkpoint. and the minute i deleted the checkpoint, the virtual server crashed and so the host was also crashed. when the host turn on and start up, i got blue screens and crashed again. then i got heart attack, cause its a production server... after i myself recoverd , i try to start up with Last Known good configuration, and somehow a miracale happend and the server turn on and startup correctly. now again i have 168 GB free space. and no checkpoints of course.

After a few days, i tried to install backup software, which did somekind of snapshot before the backup started, and the server crashed again with blue screens. again i started the server with Last known good configuration and now it's fine.

My question is why the checkpoint get the server crashed ? is it because of low disk space ? maybe hard disk fault ?

I also can tell that in the event viewer i see sometimes (every couple of days) some disk warning - The IO operation at logical block address 0x1b241d60 for Disk 0 (PDO name: \Device\Ide\IdeDeviceP0T0L0-0) was retried.

 Please assist.
