[SECURITY] Fedora 7 Update: xen-3.1.0-6.fc7



--------------------------------------------------------------------------------
Fedora Update Notification
FEDORA-2007-2270
2007-10-03 21:11:03
--------------------------------------------------------------------------------

Name        : xen
Product     : Fedora 7
Version     : 3.1.0
Release     : 6.fc7
URL         : http://www.cl.cam.ac.uk/Research/SRG/netos/xen/index.html
Summary     : Xen is a virtual machine monitor
Description :
This package contains the Xen hypervisor and Xen tools, needed to
run virtual machines on x86 systems, together with the kernel-xen*
packages.  Information on how to use Xen can be found at the Xen
project pages.

Virtualisation can be used to run multiple versions or multiple
Linux distributions on one system, or to test untrusted applications
in a sandboxed environment.

--------------------------------------------------------------------------------
Update Information:

Fixes a security flaw in pygrub handling of config files and a denial-of-service case in ne2k NIC for QEMU.

Fixes the case of disappearing network cards in fully-virtualized guests. NB, it only fixes it for guests created after this errata is installed & XenD restarted. Any pre-existing guests may continue to have problems. To fix existing guests, first ensure XenD has been restarted (service xend restart), then use virt-manager/virsh to remove the network card, and then add it back. This will correct the configuration stored in XenD permanently.
