RHBA-2010:0714 - Bug Fix Advisory

Topic

Updated kvm packages that resolve several issues are now available.

Description

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux
on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the
standard Red Hat Enterprise Linux kernel. KVM can run multiple unmodified,
virtualized guest Windows and Linux operating systems.

These updated kvm packages provide fixes for the following bugs:

• When a new virtual guest was created from a template, using Red Hat Enterprise

Virtualization Manager on NFS storage, which was mounted remotely, it was
handled by the qemu-img command. This operation took a considerable amount of
time, about an hour for a 5-10GB image. With this update, the convert operation
no longer results in poor performance and works as expected. (BZ#629574)

• Previously, the debug info package was missing from

kvm-qemu-img-83-164.el5_5.12. With this update, it is included. (BZ#629635)

All KVM users should upgrade to these updated packages, which contain backported
patches to resolve these issues.
