Unable to automatically download the systemvm template in a multihypervisor cluster/environment

### problem

Unable to automatically download the systemvm template in a multihypervisor cluster/environment

### versions

ACS 4.22 , vmware 8 and kvm 24.0.4

### The steps to reproduce the bug

1. Create a Cloudstack environment with 2 clusters ( vmware )

2. Launch systemvm's on the vmware cluster, make sure they are in running state

3. Create a KVM cluster , make sure add a KVM host and a primary storage

4. The systemvm-template for the kvm cluster will not get downloaded automatically , it will be struck in Not ready state

Workaround

login to the running ssvm on the vmware cluster and restart the cloud-service

service cloud restart

This will trigger the download of the systemvm template for kvm

### What to do about it?

Cloudstack should automatically download the systemvm template for the kvm cluster and manually restart of the cloud service should not be needed

使用 ACS 4.22，按照列出的步驟在 VMware 和 KVM 叢集中重現此問題，並觀察 KVM 的 systemvm-template 仍為 Not ready。調查系統 VM 範本的下載流程，並驗證 KVM 範本是否會在執行中的 VMware 系統 VM 上無需重新啟動 cloud-service 即自動下載。
