		+
		+	Let's enter the management namespace of the guest (that's what -i 0 is for):
		+
		+	<source lang="sh">
		+	vnamespace -i 0 -e <guest-xid> -- /bin/bash
		+	</source>
		+
		+	Now you have access to all host devices; mount the device that contains your directory wherever you want, but you may prefer to mount it in the same location you used on the host. (Note, though, that it's not even necessary for the device to be mounted in the host namespace at all.)
		+
		+	It's likely best to use mount -n lest your host /etc/mtab get polluted with mounts from other namespaces.
		+
		+	<source lang="sh">
		+	mount -n /dev/sr0 /media/cdrom
		+	exit
		+	</source>
		+
		+	We're now back in the host namespace. vmount can now be used to bind mount /media/cdrom/foo inside a running guest (in this example, under /foo inside the vserver root):
		+	<source lang="sh">
		+	vmount guestname -- --bind /media/cdrom/foo /mnt/foo
		+	</source>
		+
		+	=Resizing tmpfs in running guest=
		+	<source lang="sh">
		+	vnamespace -e 11 chroot /data/vservers/sandbox mount -t tmpfs -o remount,size=4g none /tmp
		+	</source>
