VM Instance

Modifies Network Configuration of Running VMs

Starting from ZStack Cloud 4.6.11, you can configure static IPs for VM instances and deploy network configurations through GuestTools, which meets the network configuration needs in scenarios without DHCP services.

Integrates QGA into GuestTools

In earlier versions, ZStack Cloud provides GuestTools to integrate multiple tools and drivers that help improve the VM performance, such as internal agent and VirtIO driver (Windows VM instances only).

Starting from ZStack Cloud 4.6.11, the GuestTools further integrates Qemu Guest Agent (QGA) to deploy VM instance configurations. You can conduct O&M operations on VM instances with GuestTools installed, such as modifying VM password, syncing with host system time, and syncing NIC configurations.
Figure 1. GuestTools Integrates with QGA


Configures Static IPs for VMs Based on QGA

In earlier versions, ZStack Cloud assigns and deploys network configurations based on the DHCP service. The NIC acquires an IP address in a dynamic mode (DHCP).

Starting from ZStack Cloud 4.6.11, you can configure static IP addresses for VM instances. There is no need to enable DHCP service, and you can deploy network configurations to the NIC through the QGA in the GuestTools.

For example, if you create a VM instance using the network that is not enabled with DHCP service, you need to install the GuestTools after VM creation and manually sync the network configurations to the NIC. This way, the specified parameters on the Cloud will be deployed to the NIC and take effect.

In addition, if you attach a NIC to or change the NIC IP address for a VM instance installed with GuestTools, the configurations can be automatically deployed to the NIC by QGA. You do not need to run commands in VM console to restart its DHCP service to make configurations take effect.

Supports Domestic Linux OS

To date, the optimizations described above support some domestic Linux operating systems, including Kylin V10 SP1 (0518) and UOS V20 1050e. The above optimizations will work to be compatible with more operating systems in the future.

Note: In ZStack Cloud 4.6.11, the QGA contained in the GuestTools is used mainly to sync VM NIC configurations. Note that in this version, the VM internal monitoring still relies on the internal monitoring (responsible for catching the monitoring data) and the DHCP service (responsible for pushing the caught data to the host). If you install GuestTools out of the target of viewing the VM internal monitoring, make sure that you have enabled the DHCP service for the VM default L3 network in advance.

Supports Creating Volumes with Custom Offerings

In earlier versions, you need to create a disk offering or add a volume image before creating a data volume.

Starting from ZStack Cloud 4.6.11, you can create a data volume with a custom offering, which allows you to directly specify the volume size. The volume creation is no longer bound by preconditions of existing disk offering, which better covers the fast creation scenario.

Cloud Network

Allows to Specify IPv4/IPv6 Addresses When Attaching VPC/Public Networks to VPC vRouters

Starting from ZStack Cloud 4.6.11, you can specify IPv4 or IPv6 addresses when attaching a VPC network or public network to a VPC vRouter. The input box displays 5 recommended IP addresses by default, and if the current network has less than 5 available IP addresses, all available IP addresses will be displayed. You can either select an IP address from the drop-down list or enter an IP address.

Cryptography Security Compliance

Begins to Support FLKSEC

In earlier versions, ZStack Cloud supports third-party HSMs, for example, NetSign, to provide identity authentication and data protection.

ZStack Cloud 4.6.11 begins to support FLKSEC. You can enable the platform cryptography security compliance based on the added and enabled HSMs to provide certificate login and data protection features.

Backup Service

Automatically Deletes Temporary Images When Recovering Backup Data

In earlier versions, ZStack Cloud already supports the auto-deletion of temporary images. Starting from ZStack Cloud 4.6.11, the Temporary Image Auto Deletion in the Global Setting is set to true by default. The Cloud automatically deletes temporary images generated while cloning VM instances or recovering VM instances or volumes from backups.

Continuous Data Protection (CDP)

Optimizes Auto-Start Mechanism for Stopped CDP Tasks

ZStack Cloud 4.6.11 optimizes the auto-start mechanism for stopped CDP tasks. When the CDP task is stopped due to data latency in high I/O scenarios, ZStack Cloud will continue to start CDP tasks to ensure business continuity.

V2V Migration

Supports Displaying Names of Source VMs When Creating V2V Jobs (From KVM Platform to the Cloud)

In earlier versions, the source VM instances are displayed only by UUIDs when you create a V2V job to migrate VM instances from a KVM platform to the Cloud, which is not easy to quickly identify in large-scale scenarios. Starting from ZStack Cloud 4.6.11, the V2V job supports displaying the names of source VM instances. You can quickly select VM instances to be migrated by VM names, thus improving resource O&M efficiency.

Global Notification

Updates Browser Version Requirements for the Cloud

ZStack Cloud 4.6.11 updates the supported version of your browser. For a better experience, we recommend that you use Google Chrome 66 or above, and make sure that your screen is 1280x900 pixels or above.
