Virtualizor Launched (Stable Branch)


The Virtualizor Team has released Virtualizor
This version introduces some great improvements and bugfix.

This version has the following changes :

1) [Feature] Virtualizor now supports XEN installation on Centos 7+

2) [Feature] Added Master setting to enable HVM flag by default for the Create VPS. Admin can also uncheck the checkbox while creating the VPS.

3) [Feature] Added Two Factor Authentication for Admin Panel.

4) [Feature] Added setting for Auto Deletion of Enduser ISO. Admin can set the hours after which the enduser ISO will be deleted. Notice will be shown to the enduser after which their ISO will be deleted in enduser panel.

5) [Task] Improved enduser SDK. Now Admin API key and pass can be used in the enduser SDK to perform actions. NOTE : This is just an SDK change and not an API level change.

6) [Task] Added setting to Disable Backup emails / Set Backup Email. So that emails related will be turned off / will be sent to backup email. Error email will be sent forcefully.

7) [Task] Implemented backups as per the Service Period of VPS.

8) [Task] Now Virtuozzo KVM, Virtuozzo OpenVZ and OpenVZ will preserve the state of the container / VM after node reboot.

9) [Task] Added setting for disabling use of virt-top utility which was used to gather CPU usage of VMs. NOTE: If this setting is turned on CPU usage will not be shown on List VPS wizard.

10) [Task] Updated phpMyAdmin to latest version 4.7.5

11) [BugFix] List services wizard was not working on servers with CentOS 7 OS. This is Fixed.

12) [BugFix] Admin was not able to manage (Start, Stop or Restart) the services from Services Wizard for Slave servers. This is Fixed.

13) [BugFix] In Mail to Users wizard if Subject had apostrophe “‘” it was changed to html entity when mail was sent. This is fixed.

14) [BugFix] If in bridge file the PREFIX was specified as 32, virtnetwork was not getting started. This is fixed.

15) [BugFix] LetsEncypt was not installing SSL certificate as the agreement link was outdated. This is fixed.

16) [BugFix] If a VM had 2 Disk assigned (From Admin Panel) and if that VM was edited from Cloud User Panel, total disk space was getting calculated and added to Primary disk and second disk was getting removed. This is fixed. Now if the VM is edited from Cloud user panel the changed space will be added to primary disk without affecting the secondary disks.

17) [BugFix] There was bug for Thin Pool storage. Virtualizor was creating the snapshot outside the pool and due to that if the space was not there, backup was failing even though enough space was there inside the Thin Pool. This is fixed. Now Virtualizor will create snapshot inside the Thin Pool.

18) [BugFix] Virtualizor was not able to add ebtables rules for VMs imported from SolusVM. This is fixed.

19) [BugFix] Virtualizor was not able to detect the proper vifname for VMs imported from SolusVM for XEN virtualization. Note : The vifname will be used as per SolusVM until the VM is rebooted.

20) [BugFix] On XEN Nodes Ebatbles rules were not getting deleted even after deletion of VM. This is fixed.
NOTE: We request Admin(s) to flush ebatble rules once and recreate it from Virtualizor Admin Panel -> Virtual Server -> List VPS -> Select All VMs -> Select “Update Network Rule” from the dropdown at the bottom of the page and click on Go button. It will recreate the ebtables rules for the selected VMs.

28) [BugFix] If Backup Queue was set as more than 1, at that time Backups were failing on OpenVZ node. This is fixed.

30) [BugFix] Admin SDK was not able to get the slave servers stats and vps stats. This is fixed.

31) [BugFix] If a VM was created with more than 4 Disks and / or ISO(s), and if VirtIO disk driver was selected, at that time the VM was not able to start. This is fixed.
