VM Console Enhancements

ZStack Cloud 5.0.0 makes following enhancements on VM consoles.

Supports Power Management in VM Consoles

Starting from ZStack Cloud 5.0.0, VM power managements are supported on VM console pages, which effectively improves the VM O&M efficiency. Supported operations now include stopping, rebooting, resuming, pausing, and powering off VM instances.

Starting VM instances is not supported in VM consoles. You need to exercise this operation on the VM main list or on the VM details page.

Allows You to Reboot VM Instance without Interrupting the Console Connection

In previous versions, rebooting VM instance interrupts the connection to the VM console. After the rebooting, you have to manually relaunch a console page to continue your operations in the console.

Starting from ZStack Cloud 5.0.0, an existing VM console connection will automatically recover after a VM rebooting. This allows you to continue your operations in the VM console without launching a new console page and enhances your usage experience.

VM Console Page Automatically Adapts to the Browser Resolution

Starting from ZStack Cloud 5.0.0, VM console pages can adapts to the browser resolution automatically, ensuring a clear and complete console screen regardless of the browser resolution value.
