[Xen-users] python: how do I know if domainU was rebooted.

[Wensheng Wang <wenshengwang@xxxxxxxxx>]

Hi,
I want to write a script to monitor domain U's,  and take note if a domain was rebooted.
I noticed if a domain is shutdown (halt) and then started again I have
a record. However if a domain was just rebooted(either by type 'reboot'
from inside domain or type 'xm shutdown -R' from outside), I have no
record.

I found out what caused it. If a domain was rebooted, its uptime, start_time will not be reset.
for example, xen.sv.util.getDomInfoHash('sarge1') will give up_time, start_time etc. for domain "sarge1"
now after I rebooted sarge1,
xen.sv.util.getDomInfoHash('sarge1')['up_time'] will continue grow, and start_time doesn't change!

same thing if I use xen.xend.XendClient.server.xend_domain('sarge1')

So how can I determine if a domain was rebooted or rnot?

I use xen-devel 3.0 from fedora core 4.

Thanks
