| ==Virtualization==
| | {{header|docs}} |
|
| |
|
| Virtualization in Fedora 10 includes major changes, and new features, that continue to support the Xen and KVM platforms.
| | {{Docs_beat_closed}} |
|
| |
| === Unified Kernel Image ===
| |
| The <code>kernel-xen</code> package has been obsoleted by the integration of paravirtualization operations in the upstream kernel. The <code>kernel</code> in Fedora 10 supports booting as a guest domU, but will not function as a dom0 until such support is provided upstream. The most recent Fedora release with dom0 support is Fedora 8.
| |
|
| |
|
| Booting a Xen domU guest within a Fedora 10 host requires the [http://sourceforge.net/projects/kvm KVM] based <code>[http://kraxel.fedorapeople.org/xenner/ xenner]</code>. Xenner runs the guest kernel and a small Xen emulator together as a KVM guest.

| {{Admon/important | KVM requires hardware virtualization features in the host system. Systems lacking hardware virtualization will not support Xen guests at this time. }}

| === Virtualization Storage Management ===
| |
| Advances in <code>libvirt</code> now provide the ability to list, create, and delete storage volumes on remote hosts. This includes the ability to create raw sparse & non-sparse files in a directory, allocate LVM logical volumes, partition physical disks, and attach to iSCSI targets.
| |
| | |
| This enables the <code>virt-manager</code> tool to remote provision new guest domains, and manage the storage associated with them. It provides improved SELinux integration, since the APIs will be able to ensure that all storage volumes have the correct SELinux security context when being assigned to a guest.
| |
| | |
| '''Features'''
| |
| * List storage volumes in a directory, and allocate new volumes, raw files both sparse and non-sparse, and formats supported by qemu-img (cow, qcow, qcow2, vmdk, etc)
| |
| * List partitions in a disk, and allocate new partitions from free space
| |
| * Connect to an iSCSI server and list volumes associated with an exported target
| |
| * List logical volumes in an LVM volume group, and allocate new LVM logical volumes
| |
| * Automatically assign correct SELinux security context label to all volumes when associating with a guest (ie, virt_image_t)
| |

| === Other Improvements ===
| |
| Fedora also includes the following virtualization improvements:
| |
| * storage and network paravirtual-drivers for KVM guests
| |
| * full support for monitoring network and block statistics of QEMU and KVM in <code>libvirt</code> and <code>virt-top</code>, bringing parity with statistics monitoring, previously only available to Xen guests
