Developers of XCP-ng
Those having the 8.0 RC1 running, does live migration from shared storage to local storage (on the same host that is currently running the VM) work for you?
The new kernel has the same version, except that it has been patched for a security issue. All good.
There's no such thing as XCP-ng 8.0.0-12 either. 12 is the release number of the xcp-ng-release RPM package, version is 8.0.0.
I think it's somewhere in the topic I linked. @pdonias is the lead dev on this
