MY VM DOES NOT WORK PROPERLY WITH IPV6.
For the following steps, you need to connect to your VM using the Cyclades connection guide . If your VM cannot be reached though the Internet, we suggest you use the console, as described in the above guide.
If your VM is a Windows Server, Centos, Oracle Linux Ubuntu Server or OpenSUSE VM, you can follow the recommendations below. Else, you can contact us to look into your issue further.
If you have an Ubuntu Server VM that was created before 20 December 2013 and does not have an IPv6 address, then you have stumbled upon a Network Manager bug.
Briefly, the problem is that this version of Network Manager does not take into account the settings of the /etc/sysctl.d/10-ipv6-privacy.conf file.
To bypass this issue, copy the contents of the above file to the /etc/sysctl.conf file with the following command:
sudo grep ^net /etc/sysctl.d/10-ipv6-privacy.conf >> /etc/sysctl.conf
and then restart the Network Manager:
sudo /etc/init.d/network-manager restart
Windows Server 2008/2012
If you have a Windows Server 2008/2012 VM that was created before 24 January 2014, then the problem is that your VirtIO drivers are outdated. You can update your VirtIO drivers using our VirtIO installation guide.
All Centos/Oracle Linux VMs that are created from official ~okeanos global Images do not have IPv6 nameservers. To see how to add them, we suggest you follow this CentOS/Oracle Linux guide.
If you have an OpenSUSE VM that was created before 24 February 2014, you will need to open a port in the YaST firewall for the DHCPv6 client.
YaST has a command-line and graphical component. The following instructions are for the command line component, but roughly the same steps should apply to the graphical component too:
Type in your terminal as root:
This should open a text-based interface with various options. For the rest of the instructions, you will need to use your <Up> and <Down> arrow keys to navigate up and down, and your <Tab> key to go to different window sections. Follow the steps below:
Go to "Security and Users" and then go to "Firewall". Press <Enter> and wait.
In the new window, go to "Allowed Services" and then to "Advanced...", which is at the bottom right of the window. Press <Enter>.
A pop-up window should appear, where you should see a "UDP Ports" section. Go to this section and type:
and then choose "OK".
That's it! You can now close the window safely.
