Re: [libvirt] problem attaching/detaching disk
More information:
If I simply insert this in the XML and call "virsh create",
<disk type='file' device='disk'>
<driver name='file' type='qcow2'/>
<source
file='/vrstorm/cloud/PrivateAccounts/74d37709b07be4bbae228dfc273e4339/volumes/vol-126'/>
<target dev='vdb' bus='virtio'/>
</disk>
it would fail with
[cloudadmin@test2 images]$ virsh create vdb.xml
error: Failed to create domain from vdb.xml
error: internal error unsupported driver name 'file' for disk
'<diskname>'
On the other hand, if I change the driver name to 'qemu', not only "virsh
create" works, I can also call "virsh detach-disk <vmname> vdb" to
detach the disk successfully.
It seems to clear to me that this is a bug in libvirt attach-disk in terms of setting
driver name to 'file' instead of 'qemu'.
