Doc Type: Deprecated Functionality
Doc Text:
Cause: audio device ES1370 is available in RHEL-6, but not in RHEL-7. Consequence: guests configured with this device cannot be migrated from a RHEL-6 host to a RHEL-7 host. Workaround: reconfigure the guest to use AC97 instead of ES1370. To do this in libvirt domain XML, replace es1370 in <devices> <sound model='es1370'/> </devices> by ac97, and reboot the guest.
