Add `Hypervisor default` as cache mode for disk offerings by hsato03 · Pull Request #10282 · apache/cloudstack

hsato03 · 2025-01-27T15:30:12Z

Description

Currently, ACS provides none, write-back and write-through options as cache mode when creating disk offerings.

This PR adds the option Hypervisor default as an alternative to cache mode. By using this option, the KVM hypervisor will choose the cache mode to be used by the disk.

Disk offering creation

Compute offering with compute only disk offering creation

How Has This Been Tested?

I created a disk offering and a compute offering with compute only disk offering using the Hypervisor default as cache mode;
I deployed a VM for each offering from step 1;
I verified through virt-manager that the disk of both VMs was using the Hypervisor default cache mode, as in the screenshot below.

@hsato03 the diagnostics errors are due to shortage on storage that we are suffering but the network error:
