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

| === Improved Storage Management ===
| |
| Previously/ Fedora introduced the ability to manage existing guest domains remotely using <code>libvirt</code>. It was not possible to create new guests due to the lack of storage management capabilities. There is now a new storage management capability that can create and delete storage volumes from a remote host using <code>libvirt</code>.
| |
|
| |
| === PolicyKit Integration ===
| |
| Previously, the <code>virt-manager</code> application ran as <code>root</code> when managing a local hypervisor, and used <code>consolehelper</code> to authenticate from a desktop session. Running GTK applications as root is bad practice. PolicyKit integration now permits running <code>virt-manager</code> as a regular user.
| |
| | |
| === 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
