A domain can be in one of six states. States are shown in virsh list displays.
For example:
# virsh list ID Name State ------------------------- 0 Domain-0 running 2 sxc18 paused |
The states are:
The domain is currently running on a CPU.
The domain is blocked, and not running or able to be run. This can be caused because the domain is waiting on IO (a traditional wait state) or it has gone to sleep because there was nothing running in it.
The domain has been paused, usually through the administrator running virsh suspend. When in a paused state, the domain still consumes allocated resources like memory, but is not eligible for scheduling by the hypervisor. Run resume domain to place the domain in the running state.
The domain is in process of shutting down, but has not completely shutdown or crashed.
The domain is shut down.
The domain has crashed. Usually this state can only occur if the domain has been configured not to restart on crash. See xmdomain.cfg(5) for more information.
