Ubuntu 14.04.6 LTS about to reach its end of standard support (April 30, 2019). The software vendor Canonical, who maintains and releases updates and patches for Ubuntu 14.04.6 LTS, would no longer provide security and maintenance updates for the regular users of the operating system.
In general, any regular users using Ubuntu LTS (long-term support) version would only receive maintenance and other updates from Canonical up to five years from the date of the LTS version availability.
You can go through the following link to check life cycle of the other ubuntu versions :

We recommend you to launch and use new machines with Ubuntu 18.04 LTS or 16.04 LTS available in template browser.

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
KVM is open source software. The kernel component of KVM is included in mainline Linux, as of 2.6.20. The userspace component of KVM is included in mainline QEMU, as of 1.3.
Virtualizor support KVM virtualization and it is very stable.
KVM + Virtualizor can be installed on CentOS or Ubuntu

Hi,
The Virtualizor Team has released Virtualizor 2.9.9.0
In this version we have introduced some revolutionary features like HA for KVM, Backups for File based storage, etc. Here is the complete change list:
1. [Feature] Virtualizor now supports High Availability on KVM. Here is the guide for HA :
https://www.virtualizor.com/docs/admin/high-availability/
NOTE: This is in public beta.
2. [Feature] Added backup support for file based storage.
NOTE: This functionality is available on latest QEMU version (> 2.0.0)
NOTE: This is in public beta.
3. [Feature] Added option to set different path for different server in Backup Plan wizard. It will enable Admin to use the same plan on multiple servers with different configuration.
4. [Feature] Added option for controlling IO in the Backup/Restore process. This will help to control the high load in backup and restore process.
5. [Feature] Added WHMCS invoicing option for cloud billing module. If this option is enabled by admin, Cloud users invoices will be created in WHMCS as per resource usage in Virtualizor.
6. [Feature] Added Hooks to perform actions before starting VM, after starting VM and before deleting VM.
7. [Feature] Improved method for Adding and Removing HAproxy rules. Also rules on CentOS 7+ will now be handled properly.
8. [Feature] Added option to search tasks by Server on Tasks Page.
9. [Feature] Added option to Lock / Unlock multiple servers on List Server page.

12. [Task] While adding DNS record on Admin panel, Hostname field is now optional. Earlier it was a mandatory field.
13. [Task] If VM delete operation was performed when the VM was in Rescue Mode, Virtualizor was giving error to remove the VM from Rescue mode first and then proceed with the delete. Virtualizor will now remove the VM from rescue mode and delete the VM without giving any error.
14. [Task] Added ACL for “Reboot Server” option on Manage Server Page in Admin panel.
15. [Task] On XenServer 7.6+ VNC was not working as they have moved VNC from ports to sockets. Virtualizor now handles it correctly.
16. [Task] ACL added for Storage, Edit Storage wizards in Admin panel.
17. [Bugfix] If VM was created using VPS plan assigned with recipe, recipe was not getting executed if that VM was rebuilt from Rebuild VPS wizard. Fixed.
18. [Bugfix] If VM on solusvm had interface name as ‘vifvmkvm.0’ instead of ‘vifkvm.0’, Virtualizor was not able to detect the bandwidth of the imported VM. Fixed.
19. [Bugfix] Virtualizor was not able to mount windows template having multiple partitions on custom windows templates. Now it will try to check for multiple partition and try to mount it if possible.
20. [Bugfix] “noemail” option custom field was not working for WHMCS reseller module. Fixed.
21. [Bugfix] While using Admin SDK for novnc, websockify service was not getting started due to which if anyone has integrated with custom novnc client it was not showing the VM. Fixed.
22. [Bugfix] On Proxmox LXC, restore VPS was not working due to change in API call from proxmox. Fixed.

26. [Bugfix] On XenServer change of Hostname was not working if server pool was created. Fixed.
27. [Bugfix] If VPS Name was just a single or double digit, at that time Virtualizor was not able to remove ebtable rules. Fixed.
28. [Bugfix] On Manage VPS page, VPS Domain Forwarding wizard was not filling the list properly. Fixed.
29. [Bugfix] On Manage Server page Uptime was not updated. Fixed.
30. [Bugfix] VNC was not working for Xen PV machine whose VNC Ports were greater than 6000. Fixed. Now Xen PV machines will use ports below 6000 and Xen HVM will use ports above 6000.
31. [Bugfix] On LXC containers MTU settings were not getting applied. This is fixed.
32. [Bugfix] On Proxmox KVM and LXC, VMs were not getting deleted, if they were in suspended state. This is fixed.
