Windows 10: Problem with "quick create" Ubuntu 18.04.3 VM with enhanced mode enabled

I'm currently running Windows 2004, but this issue cropped up after the update. In Hyper-V if I "quick create" a Ubuntu 18.04, after installing, I get the error:


error: No such device: root

This just started about two days ago. After the VM is created if I enable "Enhanced Session" from the vmconnect View menu, it just keeps disconnecting the session and I wind up back at the vmconnect login screen. If I disable "Enhanced Session", I can login normally but then I don't have the benefits of an enhanced session.


Anyone experience a similar problem?

A guide how to run Ubuntu 18.04 in Enhanced Mode in Hyper-V

NOTE: This guide has been superseded. Just use Quick Create from Hyper-V, select Ubuntu.


Here is a quick guide how to run ubuntu 18.04 in enhanced mode in Hyper-V.

EDIT: This has now been modified for release version.

Please guys, do not add any comments about Virtualbox or VMware being better. Start a new thread if you wish to discuss that. The aim here is to get constructive comments about the Hyper-V mode that can be fed back to developers. I will ask @Brink to remove any such irrelevant comments.

It is actually quite easy to do.

Note: It will only work on 1803 (or Skip Ahead I believe). It will not work on FCU 1709.


It is based on this blog, but there are a couple of differences as that was based on 16.04

Sneak Peek: Taking a Spin with Enhanced Linux VMs | Virtualization Blog

Running in enhanced mode allows you to :-

a) resize screens

b) cut and paste text from host and vice versa

c) access native wndows drives

I cannot guarantee this works if the RDP default port of 3389 is changed, or if using 3rd party firewalls.

Steps are as follows:-

1) Install Ubuntu

Download Ubuntu 18.04 iso, and install it in hyper-V as generation 1 vm. I will assume install is named Ubuntu - you need name in Step 4


http://releases.ubuntu.com/18.04/ubu...ktop-amd64.iso


Be patient installing - it is very slow, even with minimal install!

-----------------------------------------------------------------------------------------

2) Modify ubuntu 18.04 to use xrdp


Code:

Now we need to edit install.sh and comment out two lines





edit it and add # in front of the two rmmod commands as so:-






Code:

Code:

Shutdown Ubuntu VM.

----------------------------------------------------------------------------------------

3) Register Ubuntu session

Run this command on host PC using powershell with admin rights

Code:

(change vmname as appropriate from Step 1). Put name in double quotes if spaces in name.

------------------------------------------------------------------------------------------

4) Start in Enhanced Mode

Restart VM, and you the get the familiar enhanced mode screen

Important:- UNCHECK Printers in local resources. There is a bug at the moment and if you leave it checked, you cannot see host drives you select.



If you forget, close down VM AND the VMCONNECT SESSION - do not restart same VMCONNECT session or else the enhanced mode screen does not pop up.

------------------------------------------------------------------------------------------------

5) Login to XRDP

You will then get the xrdp login screen, and enter username - must be lowercase.

It will now run it in enhanced mode.

Cut and Paste works now.

Shared Host Drives are now visible

 

Issues enabling Enhanced Session on 10 Pro VM

Hello guys!

This is my first post here, so go easy on me

I have been racking my brain, and have done search after search on how to solve my issue, but I have come to no suitable solution as of yet. I've seen that folks have been able to solve the problem, but no description as to what they did to solve it. It's almost like it just magically starts working I've had no such luck as of this writing.

Here is the problem:

I am attempting to install Windows 10 Pro x64 build 14393 on a Hyper-V Host which is running the same OS.

I have created the VM with no issues and installed with no issues. I can not for the life of me find out why I can not enable the features of enhanced session to be able to connect external drives, USB sticks, enable audio and enhanced graphics, etc.

So far the steps I have taken include:

1) VM created as Generation 2
2) Verified "Allow enhanced session mode" is checked in Hyper-V Enhanced Session Mode Policy server settings
3) Verified "Use enhanced session mode" is checked in Hyper-V Enhanced Session Mode user settings
4) Verified all integration services are checked under the VM settings
5) Verified Remote Desktop Services service is running on VM

Perhaps there is something I am missing? At this point, when I connect to the VM there is no ability to connect to local resources. Additionally, the "Enhanced session" option under the View menu on the VM is greyed out.

Any assistance in getting this resolved would be greatly appreciated!

 

Use Smart card in Linux VMs

Hi, I've recently enabled hyper-v on my Windows 10 pro system that's updated (June 2019). I've seen that enhanced session mode is available for both the Ubuntu 18.04 LTS and the Ubuntu 19.04 templates from the "quick create" menu. This has the ability to
access local resources from the VM when connected using enhanced session mode. By default smartcards are selected for passthrough to the Linux VMs.

My problem is that my smartcard isn't accessable by the VM. Previously I have used smartcard sharing on VMware workstation (I'm aware that full USB passthrough to a Linux VM isn't available in hyper-v), however my usual methods of using the SC for SSH authentication
- for VMware VMs and on baremetal machines - doesn't detect the card/device at all. This is either the gnupg-agent method or the PKCS11 method for public key authentication.

My SC can be used for SSH authentication on the win10 host using putty, but I really need to use it in a Linux environment.

So far my searches haven't yielded any informention on this. The last time I tested hyper-v, enhanced session mode wasn't available for Linux VMs, even if they were created from an offical template in the quick create menu. Has anyone got this working? Or
could you point me in the right direction for relavent documentation?

Thanks in advance.

(This could be in the wrong catagory...)
