question regarding the resize of vm disk
- 
 Hello, I don't understand why I can't resize me vm disk. 
 When I try I had an error vm is in use.
 anyone can explain the internal mechanism for the resizeregard

 Hi, Shutdown the VM, resize the disk, boot the VM.

 yes I undestand I must shutdown the vm but why ? 
- 
 Because the current storage stack doesn't support live resize, which is obvious after your tests.
