The Create WizardThe Create Wizard helps you gather the information necessary to create
new virtual machines. All the information in each screen is retained and can
- be backed-up-to and modified until you click Finish
+ be backed-up-to and modified until you click OK
on the last screen.
-
- The System Name screen
- Choose a name for your virtual system. The name must be non-blank,
- alphanumeric (plus underscores), contain at least one letter, and be less
- than 50 characters.
-
-
-
- The Virtualization Method screen
- Choose a virtualization method for your new system. The choices
- are:
-
- ParavirtualizedA
- paravirtualized system typically performs better than a fully virtualized
- system because certain operations — disk and network access, for
- example — have direct access to the hardware. However a
- paravirtualized VM requires a specially modified kernel. If you
- choose paravirtualized, you must make sure this specially modified kernel
- is available for the operating system you wish to install.
-
-
- Fully Virtualized
-
- A fully virtualized system simulates all the hardware for the VM,
- permitting no direct access. It allows for a greater range of operating
- systems, but generally will not perform as well as a paravirtualized
- system. Note that for some hypervisor types, full virtualization requires
- hardware support. In addition if your hardware allows it, you can
- enable hardware acceleration for your fully virtualized guest (this
- item will be grayed out unless your hardware is acceleration-capable).

-
- The Installation Media screens
- The Installation Media screens let you specify where the physical or
- virtual install media for your VM are located, so that the installer can
- find them. There are two screens, one for each type of virtual
- machine.
-
- Paravirtualized installation media
-
- A paravirtualized VM requires an install tree that follows the
- pattern of the Fedora install tree (e.g.
- this tree). The Install Media URL box lets
- you enter a URL for a tree like this. When you then go to install the
- guest, the installer will check to see if the URL you entered is
- readable, and if so download the paravirtualized install kernel and
- initrd that it will need to start the install. You can use the following
- URL types:
-
- http:
- e.g. http://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os/
-
-
- ftp:
- e.g. ftp://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os/
-
-
- nfs:
- e.g. nfs:myfileserver:/images/linux/core/6/i386/os/
-
-
- local file:
- e.g. /tmp/paravirttrees/fedora/os
-
-
-
-
- You can specify a kickstart URL for your paravirtualized VM in
- exactly the same way as the install tree described
- above. &app; will remember the last 5 URLs you
- enter in these windows, so if you are installing multiple VMs you will
- not have to type the URLs more than once.
-
-
-
- Fully Virtualized Installation Media
-
- A fully virtualized VM requires the standard installation media that
- the same non-virtualized OS would require: either an actual CD or DVD, or
- a corresponding ISO image. On the Installation Media screen for a fully
- virtualized VM, you can therefore choose the path to your CD or DVD from
- the pull-down list, or you can enter or browse to the path of the ISO
- image you have saved in your local filesystem.
- For fully virtualized VMs, &app; also
- asks for the operating system type and variant you are installing. The
- installer uses this to set the acpi and
- apic flags according to the OS type (other
- parameters may be added to this list in the future).
-
-
-
-
- Assigning Storage Space
-
-
- Designate the primary storage device for your VM. You may choose an
- existing physical or LVM partition in the Partition
- box; or, you may choose to use a file on the local filesystem. If you
- choose to use a file that does not already exist, you may specify the size
- of the file in megabytes. If you choose an existing file, that file's size
- will not change. If you use a file for your primary storage device, you
- may also choose whether to allocate the entire file
- at creation time, or whether to allow it to grow to its maximum over
- time.
-
- Sparse files can be dangerous
- You may be tempted not to allocate your entire file when your VM is
- created; filling a 5- to 10-GB file with 0s can take quite a while, and
- you will avoid this wait by not allocating the entire file and instead using a
- "sparse" file. However, be aware that this will slow down your VM's disk
- performance significantly, as the underlying OS must keep allocating more
- storage space as your VM runs. In addition, if the disk your sparse file
- is on runs out of space, your VM may crash and lose data. You may
- therefore only want to use a sparse file when testing, where guest
- creation speed could be at a premium.

-
- Allocate Memory And CPU
-
- The Memory section of this screen lets you set
- two parameters, VM Max Memory and VM
- Startup Memory. These settings work as follows:
-
- VM Max MemoryVM Max
- Memory sets the maximum memory your VM can have unless you
- reboot it with a higher setting. For paravirtualized VMs, the maximum
- memory is a boot-time kernel setting; for fully virtualized VMs, the
- maximum memory appears to the VM to be the amount of physical memory
- available.
-
-
- VM Startup Memory
- For paravirtualized VMs, VM Startup
- Memory sets the amount of memory to start the VM with. The
- VM's available memory can then be changed from &app;
- while the VM is running. For fully virtualized guests, this setting has
- no effect.
-
-
-
- The virtual CPU section of this screen lets you set the number of
- vCPUs your VM starts up with. For paravirtualized guests, this number can
- be changed while the guest is running (although never to more than the VM
- started with). For fully virtualized guests, this number can only be
- changed while the guest is not running.
-
-
-
- Validation
- The Validation screen lets you verify the setup for your new
- system. If you need to, you can back up and
- make changes. Clicking "Finish" will begin creating your virtual
- machine. If you have the &app; preferences set
- to automatically open consoles, a Console window will pop up
- as soon as the installer has downloaded the necessary images and booted
- the VM's installer.
