69but should be used with extreme caution. Note that this command only
70resizes image files, it can not resize block devices like LVM volumes.

101Remove host block device. The result is that guest generated IO is no longer
102submitted against the host device underlying the disk. Once a drive has
103been deleted, the QEMU Block layer returns -EIO which results in IO
104errors in the guest for applications that are reading/writing to the device.
