On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y

* Denial-of-service in VM during CPU hotplug operation.

A logic error when performing a CPU hotplug operation on a running
virtual machine can cause an internal error in KVM, resulting in a
denial-of-service to the virtual machine.

Under certain conditions, a CPU hotplug operation on a virtual machine
