Originally created by @cairoapcampos on GitHub (May 12, 2022).
Original GitHub issue: https://github.com/retspen/webvirtcloud/issues/499

I created a webvirtcloud container using an Ubuntu 20.04 image. I use an nginx reverse proxy in front of webvirtcloud.

I edited the file /srv/webvirtcloud/webvirtcloud/settings.py.

I changed WS_PUBLIC_PORT = 6080 to WS_PUBLIC_PORT = 443.

After this configuration I was able to access the console of Linux and Windows virtual machines.

But when I type users, passwords and commands it is slow. The digits take a long time to appear on the console screen.
On Linux the digits also do not appear correctly.

What can I do to solve this problem?

May be it is related with vm. Do you have hardware acceleration for virtualization?
İnstall virt-manager then check it if it is properly working or not, please

The machine has hardware acceleration for virtualization. Characters when using virt-manager appear normally and there is no delay.

In webvirtcloud when I type some "dirt" appears in the console and no characters. Look:

it is related with spice type console.
please convert console type to VNC. Then check again.

Where do I make this change?

My file /srv/webvirtcloud/webvirtcloud/settings.py:

#
# WebVirtCloud settings
#

# Websock port
WS_PORT = 6080

# Websock host
WS_HOST = '0.0.0.0'

# Websock public port - 80 or 443 if reverse-proxy, else 6080
WS_PUBLIC_PORT = 443

# Websock public host
WS_PUBLIC_HOST = None

# Websock public path
WS_PUBLIC_PATH = "/novncd/"

# Websock Certificate for SSL
WS_CERT = None

# List of console listen addresses
QEMU_CONSOLE_LISTEN_ADDRESSES = (
    ("127.0.0.1", "Localhost"),
    ("0.0.0.0", "All interfaces"),
)
