the Linux bonding driver aggregates multiple network interfaces into a single, local "bonded" interface. The 802.1Q specification (also known as VLAN tagging) allows multiple bridged networks to transparently share a single physical network link. When attempting to use a bonded interface and 802.1Q VLAN tagging together, the "network-bridge-bonding" networking script incorrectly called the ifdown command on interfaces other than "bond0", with the result that only the bond0 bridge became active (and not, for example, the "bond0.5" bridge). With these updated packages, using interface bonding together with 802.1Q VLAN tagging works as expected and all interfaces that are expected to become active do so, thus resolving the issue.

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.
