Preparation

Configuring an NFS export domain

1. Make sure that an NFS export domain is attached to the data center where you want to save the virtual machine.
2. For RHEV Manager to be able to import the resulting virtual machine to the data center, the virtual machine files must have the same owner (vdsm:kvm) as the NFS export directory.

   This can be achieved by adding the following NFS export settings:

   • Map all users to the anonymous account.
   • Set the user ID of the anonymous account to 36 (vdsm).
   • Set the group ID of the anonymous account to 36 (kvm).

   With these settings, files written to the directory by any user will be owned by vdsm:kvm. After the migration is finished, you may revert the NFS export settings to the original values.

   Example. In Linux, NFS exports are controlled by the /etc/exports configuration file. In this file, the line corresponding to the export directory can look as follows:

   /opt/export *(rw,sync,all_squash,anonuid=36,anongid=36)

   where /opt/export is the export path; all_squash maps all user IDs and group IDs to the anonymous account; anonuid and anongid explicitly set the user ID and group ID of the anonymous account to the specified values.

Getting bootable media

If you have installed Acronis Backup & Recovery 11.5 in the trial mode, do the following:

• Download the ISO of "Migration to RHEV media" from the Acronis Web site. Burn the ISO to a CD or DVD by using a third-party tool.

If you have installed Acronis Backup & Recovery 11.5 in the full mode, do either of the following:

• Download the ISO of either "Migration to RHEV media" or regular "Bootable media" from the Acronis Web site. Burn the ISO to a CD or DVD by using a third-party tool.

  OR

• Create the regular bootable media by using Acronis Media Builder.

Booting the machine

1. Boot the physical machine using the bootable media.
2. In the boot menu, click Acronis Backup & Recovery 11.5 or Migration to RHEV (depending on the media you have).
3. [Optional] Click Configure network... to check the network settings and to change them if necessary. These settings are used as long as the machine is booted from the media.
4. Click Manage this machine locally.
5. On the Tools menu, click Change volume representation. If the machine's operating system is Linux, make sure that the media is in the "Linux-style volume representation" mode. If the machine's operating system is Windows, make sure that the media is in the "Windows-style volume representation" mode.
