Bug

When a VM is stopped and then started again, chvm start-vm fails with:

   ERROR: Storage error: cp failed: cp: cannot stat '/root/.chvm/vms/<vm_id>/rootfs.img/.': Not a directory

Steps to reproduce

  1. Create a VM: chvm create-vm --id test --image ubuntu:latest --cpu 1 --mem 4096MB
  2. Start the VM: chvm start-vm --id test — works
  3. Stop the VM: chvm stop-vm --id test — works
  4. Start again: chvm start-vm --id test — fails

Expected behavior

start-vm should start the existing VM without re-copying the rootfs image.

Actual behavior

The start-vm code path runs a cp command that appends /. to the rootfs.img file path, treating it as a directory:

   cp: cannot stat '/root/.chvm/vms/<vm_id>/rootfs.img/.': Not a directory

Environment

  • hero_compute_server calling chvm via chvm create-vm / chvm start-vm
  • VM was deployed with deploy_vm(slice_count=1), started, stopped, then start fails on retry

Workaround

Delete and redeploy the VM instead of stop+start cycling.

Changes made:
1- skip re-creating the block image if it already exists
2- Remove stale API socket so a subsequent start doesn't get EADDRINUSE
3- added integration test to cover this part
