[pve-devel] [PATCH qemu-server v2 44/49] live import/restore: query which node to use for operation

[Fiona Ebner]

In preparation for the switch to -blockdev.

Otherwise, there would be an error:
> An error occurred during live-restore: VM 103 qmp command
> 'block-stream' failed - Permission conflict on node
> 'a25d9b2028b5a364dddbb033603b68c': permissions 'write' are both
> required by node 'drive-ide0' (uses node
> 'a25d9b2028b5a364dddbb033603b68c' as 'file' child) and unshared
> by stream job 'restore-drive-ide0' (uses node
> 'a25d9b2028b5a364dddbb033603b68c' as 'intermediate node' child).
