7.4.1 Updating SLE 10 Virtual Machines to
Typically, the guest operating system on a virtual machine can be updated using the
same procedures as if running on a physical machine. However, SLE 10 virtual machines
created on a SLE 10 host need to be updated to SLE 11 by recreating the virtual machine
from the settings stored in the virtual machine's configuration file. For more detail, see
Section 6.1, "Updating SLE 10 VM Host Server Systems to SLE 11"
SLE 10 virtual machines created on a SLE 10 SP1 host do not need to follow the same
procedures to be updated to SLE 11. In addition, SLE 10 did not support SLE 10 fully
virtual machines.
NOTE
In SLE 10, changing the configuration of a virtual machine by editing its confi-
guration file (etc/xen/vm/vm_name) was acceptable. In SLE 10 SP1 and later,
editing the configuration file is no longer recommended. Instead, virtual machine
configuration changes should be made in Virtual Machine Manager and by
editing virtual machine settings stored in the xend database.
To update a SLE 10 virtual machine to SLE 10 SP1 or SLE 11, complete the following
procedure.
78 Virtualization with Xen
SLE 11
1 Make sure the host computer is running the most recent SLE updates. The
host computer must be running software that is more recent than the software
planned for the virtual machine update.
2 Shut down the virtual machine you want to update.
3 Prepare the virtual machine's operating system environment for the update
by completing any prerequisite tasks. It is recommended to make a copy of
the entire virtual disk.
4 View or print the virtual machine's configuration found with xm list -l
<vm_name>.
5 Use Virtual Machine Manager to create a new virtual machine.
