10:01 a.m.
Add a new parameter to virsh domstate, --info, to report additional
information for the domain state, e.g. for a QEMU guest running a S390
domain:
virsh # domstate --info guest-1
crashed (panicked)
s390.core = 0
s390.psw-mask = 0x0002000180000000
s390.psw-addr = 0x000000000010f146
s390.reason = disabled-wait
When the --info parameter is specified and the new API
virDomainGetStateParams is not available for the server or not supported
by the hypervisor driver an error is reported.
The --info parameter implies the --reason parameter and if additional
information is not available, the output is identical.
