you assigned pCPUs 1 and 2 to VMs 1 and 2 (via the ACRN Configurator). vCPU 1
of VM 0 and vCPU 0 of VM 1 and VM 2 are running on the same physical CPU;
they are sharing the physical CPU execution time. The thread state column
shows the current states of the vCPUs. BLOCKED state means the vCPU is
waiting for an I/O operation to be completed. Once it is done, the state will
change to RUNNABLE. When this vCPU gets its pCPU execution time, its state
will change to RUNNING, then the vCPU is actually running on the pCPU.
shows the current states of the vCPUs. The BLOCKED state can occur for
different reasons, most likely the vCPU is waiting for an I/O operation to be
completed. Once it is done, the state will change to RUNNABLE. When this vCPU
gets its pCPU execution time, its state will change to RUNNING, then the vCPU
is actually running on the pCPU.
