The live migrate is working as expected, but when testing the fault tolerance using the host_hook, we noticed the following error: [TM][I]:  ln -s "/dev/vg-nebula/lv-one-144" "/var/lib/one/datastores/109/393/disk.0"" failed: ln: failed to create symbolic link `/var/lib/one/datastores/109/393/disk.0': File exists [TM][E]: Error linking /dev/vg-nebula/lv-one-144 I understand the error. When I kill one node and host_hook kicks in, being the storage shared between nodes, the symlinks to the images are already there. My question is regarding the hook definition: HOST_HOOK = [     name      = "error",     on        = "ERROR",     command   = "ft/host_error.rb",     arguments = "$ID -r",     remote    = "no" ] Is it possible to configure the hook to delete the VM, and afterwards creating it? We tried combining "-d" and "-r" flags but only one flag seems to be used. Thanks in advance.
