So I should be able to follow this guide: https://xcp-ng.org/docs/compute.html#pci-passthrough and blacklist the GPU from Dom0 without any issues.

I am planning on adding a graphics card to my server. I have currently been looking at AMD but was wondering how to setup NVIDIA Quadro. I know that consumer cards don't work but I do know that the Quadro should work.

I have installed XO in Ubuntu and have setup https. But I want http to redirect to https so to make life easier but I have no idea how to configure this. Below is my current configuration. The redirectToHTTPs doesn't appear to work.

# It may be necessary to run XO-Server as a privileged user (e.g. `root`) for
# instance to allow the HTTP server to listen on a
# [privileged ports](http://www.w3.org/Daemon/User/Installation/PrivilegedPorts.html).
#
# To avoid security issues, XO-Server can drop its privileges by changing the
# user and the group is running with.
#
# Note: XO-Server will change them just after reading the configuration.

# User to run XO-Server as.
#
# Note: The user can be specified using either its name or its numeric
# identifier.
#
# Default: undefined
#user = 'nobody'

# Group to run XO-Server as.
#
# Note: The group can be specified using either its name or its numeric
# identifier.
#
# Default: undefined
# group = 'nogroup'

# Configuration of the embedded HTTP server.
[http]
redirectToHttps = true

[http.cookies]
#sameSite = true
#secure = true

# Basic HTTP.
#[[http.listen]]
# Address on which the server is listening on.
#
# Sets it to 'localhost' for IP to listen only on the local host.
#
# Default: all IPv6 addresses if available, otherwise all IPv4 addresses.
# hostname = 'localhost'

# Port on which the server is listening on.
#
# Default: undefined
#port = 80

# Instead of `host` and `port` a path to a UNIX socket may be specified
# (overrides `host` and `port`).
#
# Default: undefined
# socket = './http.sock'

# # Basic HTTPS.
# #
# # You can find the list of possible options there
# # https://nodejs.org/docs/latest/api/tls.html#tls.createServer
# #
# # The only difference is the presence of the certificate and the key.
[[http.listen]]
port = 443
#
# # File containing the certificate (PEM format).
# #
# # If a chain of certificates authorities is needed, you may bundle them
# # directly in the certificate.
# #
# # Note: the order of certificates does matter, your certificate should come
# # first followed by the certificate of the above
# # certificate authority up to the root.
# #
# # Default: undefined
cert = '/opt/xen-orchestra/ssl/xosystem.pem'
#
# # File containing the private key (PEM format).
# #
# # If the key is encrypted, the passphrase will be asked at
# # server startup.
# #
# # Default: undefined
key = '/opt/xen-orchestra/ssl/xosystem.key'

# List of files/directories which will be served.
[http.mounts]
#'/any/url' = '/path/to/directory'

# List of proxied URLs (HTTP & WebSockets).
[http.proxies]

# Connection to the Redis server.
