=== 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)
For further details see [[Features/VirtStorage]].

New Tools

Utilities in the new virt-mem package provide access to process tables, interface information, dmesg, and uname of a guest from the host system.

Remote Installation of Virtual Machines

Detailed Description Fully support remote guest creation in virt-install and virt-manager. This entails allowing a way to specify existing managed storage on the remote connection, or provisioning new storage on an existing pool at install time. Install methods are either PXE or a managed cdrom.

Ideally coupled with this will be better remote connection support: use libvirt's avahi advertising to search for potential remote connections when adding a connection in virt-manager.

Benefit to Fedora Remote VM installation isn't for everyone but it's pretty compelling for folks managing more than one physical machine for virtualization. A central box can be used to do all provisioning, where previously an admin would have to interact directly with the host. This will also encourage interested users to manage their storage and installation media using libvirt's storage capabilities, whose benefits are outlined at the VirtStorage feature page.

For further information see Features/VirtRemoteInstall.
