Improve check_device_status to handle HA cases
|
|
|
|
In HA environment, sometimes xenstore status has changed but ev.wait() cannot
|
|
get the signal, it will wait until timeout, thus incorrect device status is
|
|
returned. To fix this problem, we do not depend on ev.wait() result, but read
|
|
xenstore directly to get correct device status.
