<title>Description</title>
67
<command>lxc-clone</command> Creates a new container as a copy of an existing
68
container. When the original container's rootfs is an LVM block device or
69
is on a btrfs filesystem, then a snapshotted clone can be created, taking up
70
very little initial disk space.
77
<title>Options</title>
83
<option>-o, --orig <replaceable>orig</replaceable></option>
87
The name of the original container to clone.
94
<option>-n, --new <replaceable>new</replaceable></option>
98
The name of the new container to create.
105
<option>-s, --snapshot</option>
109
The new container's rootfs should be a LVM or btrfs snapshot of the original.
116
<option>-L, --fssize <replaceable>fssize</replaceable></option>
120
In the case of a LVM-backed container, a size for the new
121
block device. By default, the new device will be made the
122
same size as the original.
129
<option>-v, --vgname <replaceable>vgname</replaceable></option>
133
For an LVM-backed container, the volume group name to use. By
141
<option>-p, --lvprefix <replaceable>lxc_lv_prefix</replaceable></option>
145
For an LVM-backed container, a string to prefix to the container name to
146
form the logical volume name. For instance, specifying
147
<command>-n c1 -p lxc_</command> will cause the container rootfs to
148
be on a logical volume called <replaceable>lxc_c1</replaceable>.
155
<option>-t, --fstype <replaceable>fstype</replaceable></option>
159
For a non-snapshot LVM clone, the file system to use for the new
160
container. Note this option is ignored when requesting a
161
snapshotted container.
