Hello All, I have changed my system layout and the old disk is removed (echo 1 > /sys/block/sdX/device/delete) from OS, but UI complains when I try to remove with the following error: Error while executing action: Cannot remove Virtual Disk. At least one of the VMs is not down. Is it a limitation of oVirt ? If so, I will open an enhancement entry in bugzilla. As far as I remember KVM allowed me to make such stuff without any issues so far. Best Regards, Strahil Nikolov
