Cluster HyperV – Windows 2016 – VM Network issue

I have a cluster hyper V in Windows 2016 .  In this cluster I have around 34 VM separate on two nodes

I have two nodes hyperv1 and hyperv2

One VM on hyperv1 can ping all VM on the same host and can ping the host hyperv1.  But this VM cannot ping all other VM’s on the other host hyperv2 and cannot ping hyperv2

This VM cannot ping the gateway also.  I cannot ping this VM from my PC .

Secondly I just create two new VM  but those VM cannot ping nothing . Those VM cannot ping the gateway  , all the VM and the hosts hyperv2 and hyperv2

Can you help me

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 10G connections and File Transfer speed

Hello,

for the past two weeks, I’ve been bashing my skull around configuring a working SET with a HyperV cluster, to no avail.

The systems are two Lenovo SR530 with 2x10G Intel x722 NICs, hosts are running 2016, guests are Windows 10 1809. 

The NICs FW and all other firmware is fully updated. The drivers are installed through Lenovo XClarity Essentials UpdateExpress and there are no more driver updates available. 

There is no antivirus or firewall on neither the hosts, nor the VMs.

After some pain, I decided to go to the sheer basics and configure:

  • Initial test with no vSwitch, just two NICs and a direct speed test and then everything below
  • iPerf host-to-host with no vSwitch configured, just a direct 10G link 
  • iPerf tests at 9.5 Gbps (great, so the NICs are working at 10G-ish)
  • Copying files between hosts works at ~700 MB/s 

Subsequent tests with a vSwitch (configuration):

  • A single 10G network adapter on each host (all other NICs disabled)
  • A single vSwitch on each host created through HyperV Manager with SR-IOV enabled, AllowManagementOS is Enabled.
  • All VM interfaces are with default settings, meaning VMQ and SR-IOV are enabled
  • A single VM on each host

The tests:

  • iPerf host-to-host with a vSwitch enabled, 10 streams (-P10 switch)
  • Copy a 4,5 GB ISO file host-to-host
  • iPerf guest-to-guest with a vSwitch, 10 streams (-P10 switch)
  • Copy a 4,5 GB ISO file guest-to-guest

The results are:

  • 4.5 Gbps (OK, I guess it’s VMQ doing something)
  • 260 MB/s stable transfer (not ideal, but OK)
  • 4.5 Gbps (OK, seems stable)
  • 10-60 MB/s unstable transfer (What-the-heck?!)

When I transfer all of this workload on the 1G NICs, eveything is working full-speed.

Additionally, when I transfer the same file from a VM on a 3rd host, which only has 1G network, to my VM which has 10G, everything is stable at 1G (line speed of the sender station).

That brings me to the conclusion that there is something very wrong with my 10G cards when they communicate with each other, but that’s as far as I can go, because I have no other machines to test 10G externally.

Bottom line - as soon as a vSwitch comes into play, the guest-to-guest file transfer speed drops to 0.3 Gbps.

So, please, any suggestions as to what I may be doing wrong or am missing would be highly valued.
