Hi i have a issue again with the local storage, i will move a vm to another host but it say,
Moving KVM system from to …
The host system is not suitable : An extra 808.87 MiB free disk space is needed to create this system (the vm is 99GB)
But the host disk usage says: 302.24 GiB of 558.45 GiB local storage
The vm is moved to the other host in the nfs storage, but default storage is local

when i remove a vm the diskspace is not reloading for localstorage (for the specific server)
so the 98.89 are not correct
the same when the default is shared (nfs) storage for the host
