my servers are in sync using only the libvirt API and ignoring the config files. I think I
am still a little unclear on exactly how transient transient is. In my mind only the
persistent and defined objects would actually have their configuration saved in a file and
persist across reboots. It's surprising to me that so-called transient objects are
also saved in config files and can persist across reboots.
Transient data is saved so that it can survive libvirtd restarts; but it
should not survive host restarts. Contents in /var/libvirt should not
survive a reboot.
I should probably add that part of the confusion to me seems to be related to the fact
that I can't find a way to have virsh tell me if something is persistent or transient,
at least with respect to a network object. There are specific flags for domains but not
for other object types.
[Your mailer doesn't wrap long lines, which makes it a bit harder to read]
# dump the persistent definition:
virsh net-dumpxml $net --inactive
# dump the transient definition, if the network is running:
virsh net-dumpxml $net
# determine which networks are persistent vs. transient:
virsh net-list --all
This design mirrors the same things done for domains.
