Bridged VirtFusion Setup (Debian 12)
I fixed up the config I linked in https://lowendtalk.com/discussion/comment/3923186 somewhat, and decided to create a thread for it for others to use since I've seen a lot of questions of how to install VirtFusion with bridged networking (and also for myself since I often don't remember to backup my shit and so this will be my backup.) This will work without issues on MAC-filtered networks like OVH, just make sure to add the respective MAC-addresses to the IP's in the VirtFusion UI once done.

Bridged VirtFusion Setup (Debian 12)
Prerequisites
First, execute the following commands in your terminal:
apt-get update apt-get install ifupdown2 bridge-utils curl unzip nano cron at -y
apt-get purge cloud-init netplan.io -y
apt-get autoremove -y
rm -rf /etc/cloud/
rm -rf /var/lib/cloud/
Install VirtFusuion
curl https://install.virtfusion.net/install-hypervisor-kvm-debian-12.sh | sh -s -- --verbose
Files to Edit
You will need to edit the following files:
/etc/network/interfaces/etc/systemd/resolved.conf
/etc/network/interfaces
This file configures your network interfaces. Here's the complete content for the file:
# The loopback network interface
auto lo
iface lo inet loopback
# Raw network port
auto enp1s0f0
iface enp1s0f0
# Uplink
auto br0
iface br0
address [Your primary IP]
gateway [Your gateway IP]
dns-nameservers 1.1.1.1 1.0.0.1
hwaddress [Your MAC address]
bridge-ports [Your network interface name]
bridge-stp off
bridge-waitport 0
bridge-fd 0
/etc/systemd/resolved.conf
This file is for systemd's network name resolution service. Here's the complete content for the file:
[Resolve]
DNS=1.1.1.1 1.0.0.1
Restart Services
After editing the files, restart the network services with these commands:
systemctl restart networking
systemctl restart systemd-networkd
systemctl restart systemd-resolved
Add to VirtFusion
The hypervisor can now be added to VirtFusion.
Optional: AWS CLI
cd /tmp
curl https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip -o awscliv2.zip
unzip awscliv2.zip
./aws/install
rm -rf /tmp/aws
rm -f /tmp/awscliv2.zip
mkdir -p /root/.aws
/root/.aws/config
- Create the file
nano -w /root/.aws/config - Configure it
Sample:
[profile virtfusion]
aws_access_key_id=[S3 Key ID]
aws_secret_access_key=[S3 Secret Key]
retry_mode = standard
max_attempts = 3
s3 =
addressing_style = path
/home/vf-data/conf/dr.json
- Create the file
nano -w /home/vf-data/conf/dr.json - Configure it
Sample (backups daily at 02:00 and prunes thereafter):
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
0 2 * * * root /usr/bin/vfcli-hv dr:backup >/dev/null 2>&1 && /usr/bin/vfcli-hv dr:prune >/dev/null 2>&1
/etc/cron.d/virtfusion_dr
- Create the file
nano -w /etc/cron.d/virtfusion_dr - Configure it
Sample (change settings to your liking):
{
"type": "S3",
"storeDirType": "Y-M-D",
"tmpDir": "home/vf-data/tmp",
"threads": 2,
"S3": {
"endpoint": "[Your S3 endpoint, such as https://s3.eu-central-003.backblazeb2.com]",
"region": "[Your S3 region, such as eu-central-003]",
"bucket": "[Your S3 bucket name]",
"compress": true,
"compressLevel": 8,
"prune": {
"enabled": true,
"keepLast": 13
}
}
}
Replace brackets.

Comments
Instead of explicitly specifying the MAC on the bridge, you can use
bridge_hw [Your network interface name]Is it Possible to Setup on Almalinux?
Debian pls
Update - i did NAT on Almalinux 8 - its working
Update - Almalinux still sucks and Virtfusion clearly recommends Debian in their docs
@emgh any tutorials for setting up IPv6?
Yeah sure, run standard Debian without netplan etc so that /etc/network/interfaces is the sole config, then, proceed to remove that file completely and finally run shutdown -r now.
You’ll be left with no internet access but it’s about the same as IPv6 practically anyway.
Thanks sempai. You should do some teaching videos on YT to share your wisdom and skillset.
Thank you, yeah I just might.
Don't forget to mention about the discounts you got from that specific provider. Maybe they can even sponsor your videos.
😡
netplan better
Depends on what you’re trying to do.
Complex networking across systems, yeah, sure.
Basic minimal networking setup for just creating a bridge for VM’s? No, not really better
@emgh @VirtFusion Virtfusion meant for VPS host companies? I see it has license cost, but I do homelab with 4 servers, thinking proxmox or cockpit or Kubernetes Virt module. Right now, just using Docker with compose, need to distribute VMs across machine. We see VirtFusion name by few providers, possibly providers adapting VirtFusion for cost and functionalities?
Proxmox will be better for homelabbing, unless you want to pay for 4x licenses (if you meant 4x bare metal).
Thanks. I meant 4x bare metal servers.
