XOA
XOA is the Xen Orchestra Appliance. XOA is a Debian VM with:
- Xen Orchestra already installed (nothing to do!)
- Tested with all bundled dependencies (QA)
- The web updater (update in one click)
- Support (+SSH support, tooling)
- Secured system (sudo, firewall)
Specifications
By default, the VM is configured with:
- 2 vCPUs
- 2GB of RAM
- 15GB of disk (10GB for
/and 5GB for/var)
For use on huge infrastructure (more than 500+ VMs), feel free to increase the RAM.
Deployment
The quickest way
The fastest and most secure way to install Xen Orchestra is to use our web deploy page. Go on https://xen-orchestra.com/#!/xoa and follow instructions.
Note: no data will be sent to our servers, it's running only between your browser and your host!
Via a bash script
Alternatively, you can deploy it by connecting to your XenServer host and executing the following:
bash -c "$(curl -s http://xoa.io/deploy)"
Note: This won't write or modify anything on your XenServer host: it will just import the XOA VM into your default storage repository.
Follow the instructions:
- Your IP configuration will be requested: it's set to DHCP by default, otherwise you can enter a fixed IP address (eg
192.168.0.10) - If DHCP is selected, the script will continue automatically. Otherwise a netmask, gateway, and DNS should be provided.
- XOA will be deployed on your default storage repository. You can move it elsewhere anytime after.
Via download the XVA
Download XOA from xen-orchestra.com. Once you've got the XVA file, you can import it with xe vm-import filename=xoa_unified.xva or via XenCenter.
After the VM is imported, you just need to start it with xe vm-start vm="XOA" or with XenCenter.
First Login
Once you have started the VM, you can access the web UI by putting the IP you configured during deployment into your web browser. If you did not configure an IP or are unsure, try one of the following methods to find it:
- Run
xe vm-list params=name-label,networks | grep -A 1 XOAon your host - Check your router's DHCP leases for an
xoalease
Note: The default Web UI credentials are admin@admin.net / admin
Registration
The first thing you need to do with your XOA is register. Read the documentation on the page dedicated to the updater/register inferface.
First console connection
If you connect via SSH or console, the default credentials are:
- user: xoa
- password: xoa
During your first connection, the system will ask you to:
- enter the current password again (
xoa) - enter your new password
- retype your new password
When it's done, you'll be disconnected, so reconnect again with your new password.
Here is an example when you connect via SSH for the first time:
$ ssh xoa@192.168.100.146
Warning: Permanently added '192.168.100.146' (ECDSA) to the list of known hosts.

Using sudo
To avoid typing sudo for any admin command, you can have a root shell with sudo -s:
[05:24 27] xoa@xoa:~$ sudo -s
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
[sudo] password for xoa:
[05:24 27] xoa:xoa$
Network configuration
XOA uses DHCP by default, so if you need to configure the IP address, please run the command xoa network static. It will ask you network details:
$ xoa network static
? Static IP for this machine 192.168.100.120
? Network mask (eg 255.255.255.0) 255.255.255.0
? Gateway 192.168.100.254
? IP of the DNS server 192.168.100.254
Xen Orchestra is now accessible in your browser at https://your-vm-ip.
You can access the VM console through XenCenter or using VNC through a SSH tunnel.
If you want to go back in DHCP, just run xoa network dhcp
SSH Pro Support
By default, if you need support, there is a dedicated user named xoa-support. We are the only one with the private key. If you want our assistance on your XOA, you can open a private tunnel with the command xoa support tunnel like below:
$ xoa support tunnel
The support tunnel has been created.
Do not stop this command before the intervention is over!
Give this id to the support: 40713
Give us this number, we'll be able to access your XOA in a secure manner. Then, close the tunnel with Ctrl+C after your issue has been solved by support.
If you want to deactivate this bundled user, you can type
chage -E 0 xoa-support. To re-activate this account, you must use thechage -E 1 xoa-support.
Firewall
By default XOA is firewalled, with only ports 22, 80 and 443 opened. You can see the current status of the firewall using the sudo ufw status verbose command:
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing)
New profiles: skip
To Action From
-- ------ ----
22 ALLOW IN Anywhere
80 ALLOW IN Anywhere

22 ALLOW IN Anywhere (v6)
80 ALLOW IN Anywhere (v6)
443 ALLOW IN Anywhere (v6)
22/tcp LIMIT IN Anywhere (v6)
If you want to open or close ports, please check the documentation of UFW.
Default XO admin account
Default user is admin@admin.net with admin as a password.
SECURITY NOTICE: create a new admin account and remove this one.
In any case, if you lose your password, you can reset the database and get the default credentials back.
Timezone
You can verify that your time is correctly set with the date command. To set XOA to your current timezone, use sudo dpkg-reconfigure tzdata.
Restart the service
You can restart Xen Orchestra by accessing XOA via SSH (or console) and running systemctl restart xo-server.service.
To check the status of xo-server, use systemctl status xo-server.service, it should display something like this:
xo-server.service - XO Server
Loaded: loaded (/etc/systemd/system/xo-server.service; enabled)

Migrate from an older XOA
If you still use the first XOA (which was not the "unified" version), you can easily migrate all your settings (ACLs, users, servers, etc) to the new version painlessly.
To do so, go into "Settings/Config" of your old XOA. Export the configuration: you'll download a config.json file.
Now go to your new unified XOA, "Settings/Config" and import the config.json file you downloaded previously, by doing a drag and drop:
That's it!
