as soon as a reverse proxy HAPROXY or nginx for example come into play, a wss:// connection will tried to be opened by the proxy, which fails (websocket not working)

Browser errors out with "cannot open connection to wss://www.example.com/socket

400 Bad websocket request

I am trying to click the open button but I get this error, what can I do? thanks

I want connect to a remote server that have multiple kvm up.
but when it start it stuck on "connecting" without any error!

what should i do?

also i'm able to connect to that server with virt-manager but it's not available on docker-virt-manager.

docker-compose:

services: 
  virt-manager:
    image: mber5/virt-manager:latest
    restart: always
    ports:
      - 8185:80
      - 7681:7681

    environment:
      HOSTS: "['qemu+ssh://[email protected]/system']"

    volumes:
      - /home/ubuntu/.ssh/id_rsa:/root/.ssh/id_rsa:ro

First of all, thank you for this project. I have been searching for such a lean solution for a long time.

The idea is as the title says. Though one can restart virt-manager through the browser-terminal, it would be more convenient to have it auto restart. Maybe this can be implemented with little effort.

I am trying to install a VM, but I am always ending up in a permission denied error for the .iso image, which I just before chose from the file browser.

Unfortunately I also can't copy the error message to the clipboard, but I took some screenshots. I guess (and hope) the error speaks for itself.

Hi,

when I connect to the graphical interface of a VM, the keyboard layout is wrong. Is it possible to change that?
In Virtmanager it is correct.

Thanks for the container! The idea is brilliant!

I have an issue, though. Container starts and I can make the connection (to qemu:///session). I can see my VMs and can start and stop them. However, when I try to open any VM I get Error connecting to graphical console: Failed to recv file descriptor: Permission denied.

I'm running Ubuntu 20.04 on the host. I can successfully connect to all my VMs via a remote virtual-manager connection from another Ubuntu machine — so my QEMU/KVM config should be fine I guess.

What could I be missing here? Pleas point me to the right direction! Thanks in advance!

Here's my docker-compose:

  virt-manager:
    container_name: virt-manager
    image: docker.io/mber5/virt-manager
    restart: unless-stopped
    environment:
      - DARK_MODE=false
      - HOSTS="['qemu:///session']"
    ports:
      - 8185:80
    volumes:
      - /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock
      - /var/lib/libvirt/images:/var/lib/libvirt/images
    devices:
      - /dev/kvm:/dev/kvm

Firstly, thanks for the container and your work here. This is a great tool, and very beneficial to all. 👏

I start the docker-compose with my normal user which is mapped to the docker group, so it has access to start the container. The container starts and I can access it via the web. I see the 3 VMs I have running on the host (the same host the container is running on). It shows the CPU graphs and they are moving, so all appears fine.

When I double click on a VM, the VM screen opens, but it shows:

Error connecting to graphical console. 
Failed to recv file descriptor: Permission denied.

It then disconnects from the host completely and I have to double click on the QEMU/KVM line to reconnect.

I can create a new VM fine. It starts and works fine too. Starting, Stopping and Deleting images works just as well, so it would appear permissions to the libvirt are working. Just when I open a VM panel, it has an issue, and kicks me out.

Running on Ubuntu.
I have privileged: "true".

Any thoughts?

Hi there,

I'm trying to connect to my server that didn't have SSH open on 22 port.

On the UI I've set manually :
qemu+ssh:///[email protected]:15052

But on the env var, When I set the var it didn't work.

-e HOSTS=['qemu+ssh:///[email protected]:15052/system']

The logs show me the following :

Thanks for the help.

Unfortunately I am unable to connect, I get following error message:

Unable to connect to libvirt qemu://root@<192.168.1.48/system.
Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory
Verify that the 'libvirtd' deamon is running on the remote host.

Running systemctl status libvirtd shows that it is active.
Any ideas?

hi @m-bers, I'm hosting VMs on OpenWRT host - https://openwrt.org/docs/guide-user/virtualization/qemu_host
I don't have libvirt, but installed the kmod-kvm-x86 package for virtualization.
what should the docker-compose be in such case?
(the first option in the README is for localhost but with libvirt volumes, while the second is for a different host)
thanks!
