Hello.
Can someone shed some light on the copy-storage-all feature? There are
many hits on google. My current questions are.
1. is it possible to do a migrate --live --copy-storage-all .... without
shared storage?
Yes, that's the point of --copy-storage-all.
2. Do i need to have a preexisting image on the destination node?
I know there has been some work to get to the point of not having to
pre-create images on the destination, but am not sure of the current
state of that work. Fastest might be to just try it and see; the error
message should be sane if it still isn't implemented.
3. Is this still true:
The current implementation of --copy-storage-all uses a qemu interface
that upstream qemu developers are reluctant to support, and risks
running into problems. We have patches under review to use a new NBD
server for migration when targeting qemu 1.4 with libvirt 1.0.2, with
much less risk
What version of libvirt and qemu are you using? Newer libvirt is indeed
able to use NBD migration for a much cleaner result.
