If your server has LVM partitioning then you can setup a thin LVM partition to contain your VPS.
In the example below your Volume Group is called vg1
lvcreate -l 100%FREE --thinpool thin_vg1 vg1
Now you can add the disk path
lvmthin:vg1 to your server's settings inside VirtPanel.
I started using VirtPanel in March 2015, the support and service is excellent. The panel is always having new features for server admins and customers added at no extra fees. If I have any server issues VirtPanel are always on hand to offer advice on resolving the issues. I highly recommend VirtPanel to anyone.John E. - xHosts.uk
I mitigated from SolusVM to VirtPanel in early 2015 because of how simple it looked compared to other control panels that are available, including SolusVM. Since they understand networking better than SolusVM it saves me a lot of time installing nodes which I can use to help grow my business further. Any complaints I have had have been corrected and it is working well for myself, my vps customers and my resellers.Lewis B. - HostSavor.com
