Changelog / Windows Virtio Drivers

HTML5 - New option for VM Console

By clicking on the screen icon in the column of virtual machines (VMs), the screen console of the VM is opened in a separate browser tab. Under certain circumstances, no cursor was displayed when using the QXL Videocard. The option “Show Dot when no cursor” in the advanced settings of the display console can solve the problem. Alternatively, the connection can also be called at any time via Remote Desktop Protocol (RDP).

New system state of a virtual machine / paused VM can not be woken up via the

admin GUI

Previously, the state of a virtual machine could be *on, idle *, or off. With the new release, a new state “PMSuspend” will be added so that VMs will wake up again with action wakeup (PM). Previously, VMs in the idle mode initiated by the operating system were just turned off or restarted. The actual problem that VMs are paused can be fixed by the energy settings with hibernation = never inside the guest.

Issues Fixed in this Version

Customized test e-mail

This action can be used to test the e-mail settings before saving. The test is successful if an e-mail from “Web Admin User” with the subject “E-Mail Test” arrives in the corresponding mailbox. This update customizes the sender of the test e-mail to ensure that all status e-mails are received.

Monitoring RAID state on Broadcom Controllers

Nagios’ active monitoring of RAID controllers from Broadcom (Avago / LSI) will be adapted with this release. Due to a behavior change, the code had to be adjusted to give a degraded RAID the status CRITICAL.

Important security relevant System Components

This update will also install/update the following important system components:

  • apt
  • SQLite 3.26.0
  • vim-8.0.0785
  • Spectre-v4-Schutz auf AMD Hardware gefixt

apt: content injection in http method / SQLite Release 3.26.0 / Vim Arbitrary Code Execution / Spectre v4 - Speculative Store Bypass (SSB)


Experts have discovered critical security holes. ZombieLoad refers to an attack on Intel processors, much like Meltdown and Spectre. AMD and the latest Intel processors are not vulnerable to the newly discovered side channel attack. All other Intel processors, however, have to be protected by adjustments in the operating system and an update of the CPU microcode. With this update the kernel-side protection mechanisms and the new microcode are introduced.

Assigned Common Vulnerabilities and Exposures (CVE) numbers:

CVE-2018-12126 / CVE-2018-12130 / CVE-2018-12127 / CVE-2019-11091


Netflix experts have discovered and released critical vulnerabilities in the Linux kernel network stack. Under certain conditions, a kernel panic can be provoked via TCP. This denial-of-service (DoS) attack is protected with this update.

The error message occurs if the partitions are recognized and the user clicks the button Next. The message means, that the installation CD of Windows needs to be inserted again.

Changed partition scheme for new installation since version 6.9.0 / Important

when replacing a node

If one of the nodes is defective, it can simply be exchanged via the “Add New Node” dialog. Due to a changed partition schemes take a few things into account.

  • Both nodes should have nearly identical hardware equipment - Both nodes must have the same version - An additional 10 GB of free space must be available on the storage volume “default” if the version of the existing node at installation was older than 6.9.0. Under “Virtual Disks” click on “Storage Volumes”, then right click on the storage volume “default” and check the free space specified under Size.
