Novell LINUX ENTERPRISE SERVER 10 SP2 - VIRTUALIZATION WITH XEN Manual page 70

SLE 10 virtual machines created on a SLE 10 SP1 host do not need to follow the same
procedures to be updated to SP1. 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, complete the following procedure.
64 Virtualization with Xen
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 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.
3 Shut down the virtual machine you want to update.
4 View or print the virtual machine's configuration file located at etc/xen/
vm/vm_name.
5 On Domain0, use Virtual Machine Manager to create a new virtual machine.
6 Choose the selection to install an operating system.
7 Specify the settings for the new virtual machine as the same settings specified
in the VM's configuration file.
Make sure the following settings in Virtual Machine Manager match those in
the VM's configuration file.
• Network MAC address
• Memory size
