Hi Laine,
The setting will be ignored after "virsh define" or when you
save after "virsh edit".
Do you think it is a bug?
Details:
SC1: define
# cat rhel.xml | grep /interface -B6
# virsh define rhel.xml
Domain 'rhel' defined from rhel.xml
# virsh

Fix a typo and update the setting in the example. The documentation

Hi,
Just a gentle ping on this patch.
Any feedback would be appreciated.
Thanks!

mapped-ram can be enabled by setting the 'save_image_format'

To use mapped-ram with QEMU:
- The 'mapped-ram' migration capability must be set to true
- The 'multifd' migration capability must be set to
