help: |
Create a KVM/LibVirt virtual machine during Morph's deployment.
Parameters:
* location: a custom URL scheme of the form `kvm+ssh://HOST/GUEST/PATH`,
where:
* HOST is the name of the host on which KVM/LibVirt is running
* GUEST is the name of the guest VM on that host
* PATH is the path to the disk image that should be created,
on that host. For example,
`kvm+ssh://alice@192.168.122.1/testsys/home/alice/testys.img` where
* `alice@192.168.122.1` is the target host as given to ssh,
**from within the development host** (which may be
different from the target host's normal address);
* `testsys` is the name of the new guest VM';
* `/home/alice/testys.img` is the pathname of the disk image files
on the target host.
* HOSTNAME=name: the hostname of the **guest** VM within the network into
which it is being deployed
* DISK_SIZE=X: the size of the VM's primary virtual hard disk. `X` should
use a suffix of `K`, `M`, or `G` (in upper or lower case) to indicate
kilo-, mega-, or gigabytes. For example, `DISK_SIZE=100G` would create a
100 gigabyte disk image. **This parameter is mandatory**.
* RAM_SIZE=X: The amount of RAM that the virtual machine should allocate for
itself from the host. `X` is interpreted in the same was as for
DISK_SIZE`, and defaults to `1G`
* VCPUS=n: the number of virtual CPUs for the VM. Allowed values 1-32. Do
not use more CPU cores than you have available physically (real cores, no
hyperthreads)
* INITRAMFS_PATH=path: the location of an initramfs for the bootloader to
tell Linux to use, rather than booting the rootfs directly.
* AUTOSTART=<VALUE>` - allowed values are `yes` and `no` (default). If the
value is 'yes', the VM will be started when it has been deployed
