------------------------------------------------------------------------------
Virtualization in Fedora [[GetVal(DocsDict,BeatsVer)]] supports both Xen and KVM
virtualization platforms. The {{{libvirt}}} API and its corresponding tools,
{{{virt-manager}}} and {{{virsh}}}, have been updated to support both KVM and Xen. Users
can choose which virtualization platform to install, and use the same tools without regard
to that choice.
- Xen in Fedora [[GetVal(DocsDict,BeatsVer)]] is based on version 3.1.0.
+ Xen in Fedora [[GetVal(DocsDict,BeatsVer)]] is based on version ??
- KVM in Fedora [[GetVal(DocsDict,BeatsVer)]] is based on version 19-1.
+ KVM in Fedora [[GetVal(DocsDict,BeatsVer)]] is based on version ??

- === Types of Virtualization ===
-
- Using Xen, both paravirtualization and full virtualization can be implemented. Under
KVM, only full virtualization is supported. Full virtualization requires a VT-capable
processor. Paravirtualization does not require special hardware, but does require the
guest OS to be modified.
-
- === Guest Operating Systems ===
-
- The Fedora [[GetVal(DocsDict,BeatsVer)]] development team has tested Xen and KVM with
Fedora Core 6, Fedora 7 and Red Hat Enterprise Linux versions 4.5 and 5.0 guests. Other
guests have not been tested. With full virtualization, users can expect reasonable success
with a large variety of operating systems, including some proprietary operating systems.
=== Changes to the Virtualization Packages ===
The following improvements have been made in the Virtualization packages in Fedora
[[GetVal(DocsDict,BeatsVer)]]:
+ * Secure remote management of guest domains
- * The applications {{{virt-manager}}} and {{{virsh}}} can now work with inactive
domains. Previously, only {{{xm}}} could handle inactive domains.
- * The mouse cursor problems with the virtual frame buffer have been fixed, for a better
user experience in GUI modes.
- * Miscellaneous other small improvements and fixes have been made.
- * 32-bit paravirtualized guests can run on a 64-bit hypervisor.
- * Fully virtualized guests support save, restore, and migration.
- * When migrating guests, the guest config is saved on the destinaton host.
- * The Xen `network-bridge` script does not use the `netloop` kernel module anymore. The
default bridge device is now called `eth0` instead of `xenbr0`. The physical device is
still renamed to `peth0`.
- * The `virt-manager` utility provides a virtual networks enabling NAT for guests on
laptops, instead of the Xen `network-bridge` script.
- * The `virt-manager` utility is translated into more languages.
- * The `virt-manager` can add and remove disks and interfaces to existing guests.
- * The `virt-manager` utility provides progress feedback when downloading images,
creating disks, and starting guests
