ZStack Cloud 4.6.21

On April 20, 2023, ZStack Cloud officially released its latest version, ZStack Cloud 4.6.21, covering a number of important features described in detail below.

Highlights

  • Flat Network Supports Disabling IP Address Management: You can self-allocate and self-manage the IP address of VM instances that are created from the flat network with IPAM disabled.
  • Supports Displaying QEMU State and Alarms in VM/Cluster: Displays QEMU state in VM/Cluster so that users can update the QEMU versions in a timely manner to avoid missing security patches or incomplete functions.
  • Optimizations of Single Sign On: The Cloud supports unified identity authentication and seamless password-free login from third-party applications.

Supports Displaying QEMU State and Alarms in VM/Cluster

Starting form ZStack Cloud 4.6.21, the Cloud supports displaying the QEMU state of resources and alerts in VM instance/cluster to help users to avoid missing security patches or incomplete functions caused by QEMU version inconsistency.

On Cluster Level

ZStack Cloud 4.6.21 supports monitoring the QEMU state of hosts in a cluster. You can timely get the information about the QEMU version of hosts through the cluster details page or an event alarm, and update the corresponding host QEMU.

Adds Alert of QEMU Version on Cluster Details Page

ZStack Cloud 4.6.21 adds an alert of QEMU version on the cluster details page. When the QEMU version of hosts in a cluster is inconsistent with the recommended version, an alert message will appear on the top of the cluster details page, advising users to check and update the host QEMU version to timely avoid security or functional use problems.

Adds Event Alarm: QEMU Version of Hosts in Cluster Needs to be Updated

In addition to the alert on details page, ZStack Cloud 4.6.21 adds a default event alarm: QEMU Version of Hosts in Cluster Needs to be Updated, which monitors and alarms the QEMU state of hosts in a cluster. You can quickly locate the corresponding cluster based on alarm messages and efficiently fix problems related to the host QEMU version.

On VM Instance Level

When the host QEMU version is updated, you need to update the VM instances on the host to make the QEMU configuration take effect. ZStack Cloud 4.6.21 supports displaying the QEMU state of VM instances/VPC vRouters/LB instances, helping users to quickly locate VM instance whose QEMU version need to be updated.

Supports Displaying and Filtering QEMU State on VM/VPC vRouter Lists

Starting from ZStack Cloud 4.6.21, a new QEMU state column is added to the VM instance/VPC vRouter list to display the QEMU version information. When the QEMU version of a VM instance/VPC vRouter is inconsistent with that of the host it resides on, the QEMU state is displayed as To be Updated. You can reboot or migrate the VM instance/VPC vRouter to update the QEMU version.

You can also filter VM instances/VPC vRouters by QEMU state. When you filter all resources whose QEMU state is To be updated, you can migrate or reboot these resources with one click to batch update the QEMU version.

Supports Displaying QEMU State on LB Instance Details Page

In addition to VM instances/VPC vRouters, ZStack Cloud 4.6.21 supports displaying the QEMU state of an LB instance. On the details page of a load balancer, click the LB instance tab and you can view the QEMU state. When the LB instance QEMU version is inconsistent with that of the host it resides on, the QEMU state is displayed as To be updated. You can reboot or migrate the instance to update its QEMU version.

Optimizations of VM Instance Hot Migration

ZStack Cloud 4.6.21 makes optimizations on the VM instance hot migration.

Supports Displaying Migration Rate and Data Migrated When Hot Migrate VM Instance

Starting from ZStack Cloud 4.6.21, when you hot migrate a VM instance (change host, change primary storage, or change host and primary storage), ZStack Cloud dynamically displays the real-time migration rate and the data migrated.

You can hover over the progress bar of Data Migrated to view the Total Data Volume, Data Migrated, and Remaining Data Volume, so as to visualize the migration progress and make business adjustment as needed.

Supports Canceling VM Hot Migration Task

When hot migrating a VM instance (change host), you can cancel the task at any time as needed and the cancellation process is business-unaware.
