Improve this question. Add a comment. Active Oldest Votes. In the past, I've had to convert them first to raw images, concatenate them together, and then convert the resulting raw image to qcow2: qemu-img convert guest-s It may be possible to do this all at once too, but I haven't tried this: qemu-img convert guest-s Changes the cluster size must be power-of-2 between 4K and 64K.
There is normally no need to change this value but this option can between used for performance benchmarking. Old QEMU image format with support for backing files, compact image files, encryption and compression.
This encryption format is considered to be flawed by modern cryptography standards, suffering from a number of design problems enumerated previously against the qcow2 image format. Users requiring native encryption should use the qcow2 format instead with encrypt. Provides the ID of a secret object that contains the encryption key encrypt.
Provides the ID of a secret object that contains the passphrase. If this option is set to on , the image is created with metadata preallocation. Specifies which VMDK subformat to use. Specifies which VHD subformat to use. Valid options are dynamic default and fixed. Specifies which VHDX subformat to use. Can be set to on default or off. Bochs images of growing type. In addition to disk image files, QEMU can directly access host devices. On Linux, you can directly use the host device filename instead of a disk image filename provided you have enough privileges to access it.
The preferred syntax is the drive letter e. Currently there is no specific code to handle removable media, so it is better to use the change or eject monitor commands to change or eject media. In order to use it, just type:. The default access is read-only. Floppies can be emulated with the :floppy: option:. If the NBD server is located on the same host, you can use an unix socket instead of an inet socket:.
In this case, the block device must be exported using qemu-nbd :. The use of qemu-nbd allows sharing of a disk between several guests:. If the nbd-server uses named exports supported since NBD 2. An alternative syntax is also available. Here are some example of the older syntax:. How to do this differs between host OSes. Username and password are optional and only used if your target is set up using CHAP authentication for access control.
Alternatively the username and password can also be set via environment variables to have these not show up in the process list:. TYPE specifies the transport type used to connect to gluster management daemon glusterd. Valid transport types are tcp and unix. HOST specifies the server where the volume file specification for the given volume resides. This can be either a hostname or an ipv4 address.
If transport type is unix, then HOST field should not be specified. Instead socket field needs to be populated with the path to unix domain socket. PORT is the port number on which glusterd is listening. This is optional and if not specified, it defaults to port If the transport type is unix, then PORT should not be specified.
Debug levels are , with 9 being the most verbose, and 0 representing no debugging output. The default level is 4. The default is stderr. Any ssh server can be used, but it must implement the sftp-server protocol.
PORT is the port number on which sshd is listening. By default the standard ssh port 22 is used. The default is yes which means to use the local. Setting this to no turns off known-hosts checking. Currently authentication must be done using ssh-agent.
