Hello again, sorry for mailing in so short time but I have another question about live migration.
From redhat documentation I see that the storage for a VM which has to be migrated has to be shared throught some mechanism and I have chosen iscsi.
Anyway I now would need a way to dinamically create a new virtual machine and so a virtual hard disk, note that this vm will have to be migrated too.
I though about this solution: I would share an HUGE iscsi target, this target is a logical hard drive containing many disk images which would be the VM's hard drives. I can easily clone a vm by making a simple file copy of a vm disk.
This would allow me to create a VM by specifying a path like <iscsi target path>/disk1.img.
I have two problems:
1)how to get an unique <iscsi target path>? On my phisical host it is mounted as a random uuid in the /media folder.
2)will migration work with a <file> instead of a <device> as hard disk field?
If you have any better solution, even involing the change from iscsi to another technology, you are free to propose it to me.
Sorry for bothering,
Pasquale
