### problem
I am attempting to migrate VMs from an external VMware cluster to CloudStack
using the Import-Export tool.
The VMware VMs are not located within the root folder of the datacenter, but
rather, they are organized into VM folders.
When the CloudStack agent attempts to run ovftool to export the VM from
VMware, it is not passing the full path of the VM to ovftool, instead it
assumes that the VM is in the root folder.
The following error is displayed in GUI:
`The convert process failed for instance vm1 from VMware to KVM on host
host1: Export OVA for the VM vm1 failed`
Logs from CloudStack Agent on the KVM host (sensitive information changed):

[resource.wrapper.LibvirtConvertInstanceCommandWrapper]
(agentRequest-Handler-1:[]) (logid:ffec67e0) Export OVA for the VM vm1 failed`
When I ran the ovftool command directly, I saw the issue. It is throwing the
error `Error: Locator does not refer to an object` because the VM at that path
does not exist.
### versions
CloudStack Management Server 4.20.0.0-1 on AlmaLinux 9.5
CloudStack Agent 4.20.0.0-1 on AlmaLinux 9.5
VMware vCenter 8.0.1 build 22088981
VMware ovftool 4.6.3 (build-24031167)
### The steps to reproduce the bug
1. Create a VM on vCenter that is located inside a VM folder.
2. Attempt to migrate the VM to CloudStack via the external vCenter server.
3. Observe that the migration fails with error
4. Check agent logs and copy/run the ovftool command, confirming that it
results in error `Error: Locator does not refer to an object`
5. Move VM to root folder of datacenter in vCenter, re-run migration,
confirming it now works OK
### What to do about it?
When CloudStack runs ovftool, it should pass the full path of the VM
including any folders or subfolders that it is in. Passing only the VM name is
not sufficient.
For example, if the VM vm1 is located in the folder Test-Folder within
datacenter DC1, the full path for ovftool would be similiar to this:
`vi://username:password@vcenter/DC1/vm/Test-Folder/vm1`
