|
|
* | pauses the User VM vCPU y
|
|
* | sets the state to PENDING (a)
|
|
* | fires an upcall to Service VM
|
|
* |
|
|
* | HSM:
|
|
* | scans for PENDING requests
|
|
* | sets the states to PROCESSING (b)
|
|

|
|
* V
|
|
* | client:
|

* | scans for the assigned requests
|

* | handles the requests (d)
|

* | HSM:
