Hello,
Firstly, I have some confusion about the
libvirt API "virDomainDestroy" method. here is the link to API: http://libvirt.org/html/libvirt-libvirt.html#virDomainDestroy
Does this method completely removes the
domain from the system? I have confusion because the "virsh destroy"
tool option performs a forced shutdown and does not destroy/delete/remove
the domain.
So, what does "virDomainDestroy"
method do exactly? Also, if it comletely removes the domain, then is there any
other method to perform a force shutdown of the domain. I know the
"virDomainShutdown" method performs a normal shutdown.
Secondly, Is it possible to boot a domain
on a completely different physical host with the same Hypervisor
configuration?
For. E.g: if I have a domain on a host
192.168.101.1 running Xen with a Domain "test" in shutdown state. If I have to
start/boot the domain "test" on a different physical host, running Xen say
192.168.101.2, is it possible using libvirt API? If not, then is there any other
method to do it?
Thirdly, Is there a method to get the
total running time of a domain? I mean, the amount of time since the domain
had been booted. Currently, I can fetch the CPU time. But, is this the exact
amount of time the domain is ON? i.e. If the domain is in a "IDLE" state, the
CPU time does not increase. But what I want is the amount of time the domain was
ON(including the idle time). So, If I can get the start time of the domain, I
can calculate the duration.
Sorry for the long mail and
description.
Any help would be greatly
appreciated.
Thanks and Regards
