[Bug 1908383] [NEW] Resume accelerator guest state when a host is booted

 

Public bug reported:

When we resume guest state with accelerator bound, we should pass
the accel_info when the guest hard reboot[1]. otherwise, the vm will lost connection with accelerator because the new vm xml not includes the accelerator hostdev.
