hi there, I'm following these documentations to add a file-based disk volume to a KVM guest under Centos 6.0 : http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/chap-Virtualization-Storage_Volumes.html as instructed, I created a "pool" then a "volume", file-based, e.g : mkdir /mnt/raid/kvm_pool1 virsh # pool-define-as pool1 dir - - - - "/mnt/raid/kvm_pool1" virsh # pool-autostart pool1 virsh # vol-create-as pool1 volume1 20G --allocation 15G --format qcow2 now I want to associate "volume1" to my guest OS. Following this doc: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/sect-Virtualization-Virtualized_block_devices-Adding_storage_devices_to_guests.html - why does this ask me to create a file with "dd" ? it's already been created before with the virsh pool commands, isn't it? Seems to me I'm bypassing the libvirt/virsh layer if I do that. - after that, the doc tells me to do some stuff with guest XML files. Is'nt there some specific commands provided by virsh to associate a managed Pool to a managed Guest ? - in this case, should I use the virsh "attach-disk" command ? thanks. -- Tom
