ZStack Cloud 4.7.11

On July 28, 2023, ZStack Cloud officially released its latest version, ZStack Cloud 4.7.11, covering a number of important features described in detail below.

Highlights

Enhancements of VM GuestTools: Realizes VM IPv6 info syncs and supports more operating systems.
Optimization of VM Deletion Mechanism: Provides a new global setting, VM Anti-Accidental-Deletion Mode, and a better experience when you delete/expunge VM instances in bulk.
Fine-Grained Monitoring Based on Network Categorization: Allows you to mark physical NIC ports with network types and view flow monitoring of different network types.
Optimization of Backup Job: Displays backup mode and backup capacity, allows you to cancel ongoing backup jobs, and supports enabling/disabling the backups of resources in backup jobs.

VM Instance

Enhancements of VM GuestTools

ZStack Cloud 4.7.11 makes the following enhancements on the VM GuestTools:

Realizes IPv6 Synchronization and Reading through GuestTools

In the earlier version, ZStack Cloud has realized IP address synchronizations and reading through the QGA in the VM GuestTools. However, this feature applies to IPv4 addresses only before 4.7.11.

Starting from ZStack Cloud 4.7.11, in addition to IPv4 addresses, the GuestTools realizes IPv6 syncs and reading. After assigning an IPv6 address to a VM NIC that uses a network without the DHCP service on the Cloud, you can click Synchronize Configurations on the NIC action list to sync the IPv6 to the NIC and take effect.

If you configure an IPv6 address manually in a VM instance, the IPv6 address can be read to and displayed on the Cloud. To read an IPv6 address, make sure the following points:

The IP address management is disabled for the L3 network that the VM NIC resides on.
You have not assigned an IPv6 address for the VM NIC on the Cloud.

The Cloud reads each IPv6 address satisfying the requirements only once. If you enter the VM instance to modify an IPv6 that has been read, an alarm will be triggered.

Supports More Operating Systems

Up to ZStack Cloud 4.7.11, the extension features realized through the QGA in VM GuestTools has been compatible with several mainstream Linux/Windows operating systems, including the NIC configuration sync and reading, online hostname modification, and VM internal monitoring without the DHCP service.

The following are operating systems that realize their compatibility with these features in ZStack Cloud 4.7.11: CentOS 6.5/6.8/6.9/7.3/7.5, Ubuntu 14.04/16.04/16.10, Redhat Enterprise Linux Server 7.4/7.6, Debian 9.9/10.0, Fedora 30/31, and Windows Server 2008 R2.

Optimization of VM Deletion Mechanism

ZStack Cloud 4.7.11 optimizes the VM deletion mechanism, helping reduce your risk of deleting resources wrongly and better ensure your business stability and data security. The following are optimization contents:

A New Global Setting: VM Anti-Accidental-Deletion Mode

ZStack Cloud 4.7.11 provides a new global switch: VM Anti-Accidental-Deletion Mode. You can turn on/off this switch in Settings > Global Setting > Basic > Deletion Policy.

If you turn on this switch, only VM instances in Stopped or Unknown status can be deleted. This effectively reduces the business interruption risk brought by an accidental deletion of a running VM instance. If you turn off this switch, any VM instances can be deleted no matter their status.

A Safer Double Confirmation before Deletion to Reduce Mis-Operation Risk

Starting from ZStack Cloud 4.7.11, you need to carefully read the risk notes and manually enter the text "Delete" to acknowledge these risks before you can make a VM instance deleted or expunged.

A Better User Experience When you Delete/Expunge VM Instances in Bulk

ZStack Cloud 4.7.11 provides a better user experience when you delete/expunge VM instances in bulk: After you select multiple VM instances and click Delete or Expunge, the VM information is displayed clearly in the pop-up confirmation window. You can recheck the selected VM list here and uncheck those misselected directly. The list supports a scrolling view in case you choose a large number of VM instances at once.

Optimizes Network Configuration Interaction When Creating VMs

ZStack Cloud 4.7.11 simplifies the interaction steps of selecting a network configuration when creating VM instances, which reduces operational fatigue and improves user experience.
