Proxmox is a pretty nice virtualisation solution for the medium enterprise. It’s bigger than Virtualbox, smaller than Openstack, and easy to implement on both as single machine or a whole cluster. Unfortunately, the developers are struggling to pay the bills. So with the 3.1 release they have followed the path of “Subscription versus Community.” Users without a subscription are now treated to this dialog every time they login:
You do not have a valid subscription for this server. Please visit www.proxmox.com to get a list of available options.
Thankfully, this is easily fixed. Apply this patch to
/usr/share/pve-manager/ext4/pvemanagerlib.js. Then logout from Proxmox, clear your browser’s cache, and login again.
If you trust me (ha ha!), just run this from your server:
wget http://www.tolaris.com/blog/wp-content/uploads/2013/08/no_subscription_popup_pvemanagerlib.js-3.1.patch -O - | patch -p0
Update 2013-08-28: I posted this to the Proxmox forums. A staff member edited it to remove the patch.
