Setup problems, /dev/net/tun FD in bad state
Hi all, I'm following the manual but I get the below error, and I
believe tinc is clobbering my conf file.
I've never set up VPN before, I'm just trying to connect to my work
network from home. All the following is on my work computer. Thanks in
advance for any help.

libvirt 0.9.9: could not open /dev/net/tun: Operation not permitted
Hi, I'm running the latest libvirt 0.9.9.
I'm trying to start a VIF of type "Ethernet". I know there are problems with that because you need to be root in order to control the tun/tap driver.
I changed my qemu.conf file to
user = "root"
group = "root"
clear_emulator_capabilities = 0
However, I still get an error when trying to start my VM:

Hi, All
Due to some routing rotation purpose, I use crontab to add below info:

What/why this event happens: Can't write to Linux tun/tap device (tun mode) /dev/net/tun: Input/output error
Hi, Guus
Thanks a lot for your suggestion, actually I did something else as below.
But one question here is if I don’t add "/sbin/ifconfig myvpn 10.0.0.1 netmask 255.255.255.0”, it seems the crontab wouldn’t trigger tinc-up, and then the ip addr of myvpn wouldn’t be configured, then it will prompt the error of "Can't write to Linux tun/tap device (tun mode) /dev/net/tun:

Examples request - tinc witn tun/utun mode=router
Hi Folks,
Does anyone have a set of config files handy, using tinc in routed/tun
mode (preferably DeviceType=utun)
I'm particularly interested to see what the tinc-up and tinc-down files
should look like when the vpn is not using tap mode.
I have this, from my tap (switch mode tinc) , but it doesn't work for
tun devices.

Persistent tun/tap
It is possible for tinc to made a persistent tun/tap or can I configure a persistent tun/tap by hand and tell to tinc to use that virtual interface device without starting up/shutting down tun/tap at every tincd start/stop ?

Persistent tun/tap
So we can configure a persistent tun and tinc on startup recognize this, tinc uses just present tun without problems ?
Can you point me to Tinc-RedHat best practice method to do that please ?
Thank you in advance

How to use /dev/net/tun from libvirt-lxc with user namespacing enabled
I have a container rootfs that I use to keep all work-related stuff. This
container was originally created by lxd (which creates all containers for
use with user namespacing), but now I decided to start using libvirt for
container management since I already use it for virtual machines, which
will spare me from dealing with multiple hypervisor technologies.
I managed to create a working domain xml
