LXD Driver LXD is a daemon which provides a REST API to drive LXC containers. Containers are lightweight OS-level Virtualization instances, they behave like Virtual Machines but don’t suffer from hardware emulation processing penalties by sharing the kernel with the host. The package provides the installation files for Microsoft USB Input Device Driver version 10.0.4. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version.
LXD supports the following network types:
- bridge: Creates an L2 bridge for connecting instances to (can provide local DHCP and DNS).
The configuration keys are namespaced with the following namespaces currently supported for all network types:
maas(MAAS network identification)
user(free form key/value for user metadata)
As one of the possible network configuration types under LXD, LXD supports creating and managing network bridges.LXD bridges can leverage underlying native Linux bridges and Open vSwitch.
Creation and management of LXD bridges is performed via the
lxc network command.A bridge created by LXD is by default 'managed' which means that LXD also will additionally set up a local
dnsmasqDHCP server and if desired also perform NAT for the bridge (this is the default.)
When a bridge is managed by LXD, configuration values under the
bridge namespace can be used to configure it.
Additionally, LXD can utilize a pre-existing Linux bridge. In this case, the bridge does not need to be created via
lxc network and can simply be referenced in an instance or profile device configuration as follows:
Network configuration properties:
A complete list of configuration settings for LXD networks can be found below.
The following configuration key namespaces are currently supported for bridge networks:
bridge(L2 interface configuration)
fan(configuration specific to the Ubuntu FAN overlay)
tunnel(cross-host tunneling configuration)
ipv4(L3 IPv4 configuration)
ipv6(L3 IPv6 configuration)
dns(DNS server and resolution configuration)
raw(raw configuration file content)
It is expected that IP addresses and subnets are given using CIDR notation (

Integration with systemd-resolved
If the system running LXD uses systemd-resolved to perform DNSlookups, it's possible to notify resolved of the domain(s) thatLXD is able to resolve. This requires telling resolved thespecific bridge(s), nameserver address(es), and dns domain(s).
For example, if LXD is using the
lxdbr0 interface, get theipv4 address with
lxc network get lxdbr0 ipv4.address command(the ipv6 can be used instead or in addition), and the domainwith
lxc network get lxdbr0 dns.domain (if unset, the domainis
lxd as shown in the table above). Then notify resolved:
lxdbr0 with the actual bridge name, and
18.104.22.168 withthe actual address of the nameserver (without the subnet netmask).
lxd with the domain name. Note the
~ before thedomain name is important; it tells resolved to use thisnameserver to look up only this domain; no matter what youractual domain name is, you should prefix it with
~. Also,since the shell may expand the
~ character, you may need toinclude it in quotes.
In newer releases of systemd, the
systemd-resolve command has beendeprecated, however it is still provided for backwards compatibility(as of this writing). The newer method to notify resolved is usingthe
resolvectl command, which would be done in two steps:
This resolved configuration will persist as long as the bridgeexists, so you must repeat this command each reboot and afterLXD is restarted. Also note this only works if the bridge
dns.mode is not
Note that depending on the
dns.domain used, you may need to disableDNSSEC in resolved to allow for DNS resolution. This can be done throughthe
DNSSEC option in
IPv6 prefix size
For optimal operation, a prefix size of 64 is preferred.Larger subnets (prefix smaller than 64) should work properly too butaren't typically that useful for SLAAC.
Smaller subnets while in theory possible when using stateful DHCPv6 forIPv6 allocation aren't properly supported by dnsmasq and may be thesource of issue. If you must use one of those, static allocation oranother standalone RA daemon be used.
Allow DHCP, DNS with Firewalld
In order to allow instances to access the DHCP and DNS server that LXD runs on the host when using firewalldyou need to add the host's bridge interface to the
trusted zone in firewalld.
To do this permanently (so that it persists after a reboot) run the following command:
E.g. for a bridged network called
lxdbr0 run the command:
This will then allow LXD's own firewall rules to take effect.
How to let Firewalld control the LXD's iptables rules
When using firewalld and LXD together, iptables rules can overlaps. For example, firewalld could erase LXD iptables rules if it is started after LXD daemon, then LXD container will not be able to do any oubound internet access.One way to fix it is to delegate to firewalld the LXD's iptables rules and to disable the LXD ones.
First step is to allow DNS and DHCP.
Then to tell to LXD totally stop to set iptables rules (because firewalld will do it):
Finally, to enable iptables firewalld's rules for LXD usecase (in this example, we suppose the bridge interface is
lxdbr0 and the associated IP range is
To check the rules are taken into account by firewalld:

There may come a time when your Windows 10-powered machine will just not recognise a USB device. This issue has existed on Windows since the days of Windows 98, and sadly, Windows 10 also seems to have inherited the quirk. Thankfully it isn’t difficult to make your device detect your USB device. Follow the below-mentioned methods to see if your computer gains senses and stars detecting your device.
As Moss and Roy famously put it in The IT Crowd TV show, a simple restart can do wonders for you. So plug out the device, reboot the computer and plug it back in to see if anything changes.
Sometimes your USB device, which is plug-and-play nature really need a set of codes, in this case known as a driver, to interact with your device. If the computer prompts you to install a driver, let it try. If it doesn’t, go to Control Panel > Printers and devices to see if there is any Unidentified USB device or Unknown device listed there. In case there is, go to its Properties and update its driver. You might again need to reboot the machine, Alternatively, you might want to visit USB device’s manufacturer website to get a driver for it.
Plug-out all other USB devices
If your newly inserted device isn’t getting read by the computer, try disconnecting other USB devices to see if anything helps. Sometimes having multiple devices on the machine may create a conflict.

Fix USB Root Hub
If the aforementioned methods still don’t make your device recognisable, you could try opening Device Manager, expanding USB Serial Bus controllers. Once there, right click on USB Root Hub and click Properties. Click on the Power Management tab and uncheck the option that says “Allow the computer to turn off this device to save power”. If there are more than one USB Root Hub listed, you will need to perform the same with every entry. Click OK and restart your computer. Plug back the USB device in and see if the computer is able to recognise it.
Try a different computer / operating system
Lxd Input Devices Driver Device
If your USB device is still not showing up on the system, you might want to try it on any other device, and also check if it works on any other operating system. In case it does, transfer all your important files onto a different device. In case it doesn’t, we’re afraid your USB device has probably gone rogue.
