RHBA-2009:0401 - xen bug fix update

Synopsis

xen bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated Xen packages that fix various bugs are now available.

Description

Xen is a high performance and secure open source virtualization framework. Virtualization allows users to run guest operating systems in virtual machines on top of a host operating system.

Bugs fixed in these updated packages include:

  • Data corruption occurred on guests with virtual SCSI disks larger than 1TB. This update adds support for virtual disks larger than 1TB.

  • Various SCSI device data corruption issues occurred on fully virtualized guests with over 4GB of RAM. This update resolves the data corruption issues on fully virtualized guests with over 4GB of RAM.

  • The Xen SCSI driver scsi_write_data() system call did not verify data if was written before returning. The SCSI driver now flushes the buffer before it returns which ensures data is written to the disk.

Users of Xen are advised to upgrade to these updated packages, which fix these bugs.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
