Re: [libvirt-users] about guest live migration configuration changes persistence ..

Hi, Thanks for infos. My concern is the following : In order to establish datas exchanges between hosts and guest , I'll add a channel device to a running Guest ( as I learned from you that it's possible to do that without stopping the Guest). When the guest migrates to another host , this one must be able to retrieve the channel device parameters to be able to dialog with the migrated guest. I plan to use dumpxml to retrieve these infos. Will these infos be updated on the second host where the guest has migrated ? Thx.

However, by default, migrated domains are just transient (unless you pass VIR_MIGRATE_PERSIST_DEST flag, or virsh migrate --persistent ..) so the configuration XML doesn't have much effect in that case.
