Heap-based buffer overflow in the process_tx_desc function in the
e1000 emulation allows the guest to cause a denial of service (QEMU
crash) and possibly execute arbitrary code via crafted legacy mode
packets.
Bump PKGREVISION
from qemu upstream:
Fill in word 64 of IDENTIFY data to indicate support for PIO modes 3 and 4.
This allows NetBSD guests to use UltraDMA modes instead of just PIO mode 0.
With this patch I can no longer reproduce PR 42455.
Bump package revision.
* Security fixes including CVE-2011-1583 CVE-2011-1898
* Enhancements to guest introspection (VM single stepping support for very
fine-grained access control)
* Many stability improvements, such as: PV-on-HVM stability fixes (fixing
some IRQ issues), XSAVE cpu feature support for PV guests (allows safe use of
latest multimedia instructions), RAS fixes for high availability, fixes for
offlining bad pages and changes to libxc, mainly of benefit to libvirt
* Compatibility fixes for newer Linux guests, newer compilers, some old
guest savefiles, newer Python, grub2, some hardware/BIOS bugs.
- use the correct way to get the size of a disk device or partition (from
haad@NetBSD.org)
- if given a block device, use the character device instead (the block device
is already in use by the backend driver).
With this I could succeffully boot a HVMPV FreeBSD kernel using a phy:
virtual disk.
on a single physical machine. The xentools41 package contains the
tools to create, destroy and control the virtual machines.
This package contains the tools for Xen 4.1.x
Release notes:
The Xen team is pleased to announce the release of Xen 4.1.
The result of nearly 12 months of development, new features include:
* A re-architected and improved XL toolstack replacing XM/XEND
* Prototype credit2 scheduler designed for latency-sensitive workloads and
very large systems.
* CPU Pools for advanced partitioning.
* Support for large systems (>255 processors)
* Support for x86 Advanced Vector eXtension (AVX).
* New Memory Access API enabling integration of 3rd party security
solutions into Xen virtualized environments.
* Many IOMMU fixes (both Intel VT-d IOMMU and AMD IOMMU).
* Many toolstack and buildsystem fixes for Linux and NetBSD hosts.
* Thirdparty libs: libvirt driver for libxl has been merged to upstream
libvirt.
* HVM guest PXE boot enhancements, replacing gPXE with iPXE.
* Even better stability through our new automated regression tests.
