It can be reproduced with libvirt,and will displays error as following: virsh # change-media Server-base sdc /home/kvm_autotest_root/iso/linux/RHEL7.2-Server-x86_64.iso error: Failed to complete action update on media error: internal error: unable to execute QEMU command 'change': aio=native was specified, but it requires cache.direct=on, which was not specified. the configuration of cdrom in xml: <disk type='file' device='cdrom'> <driver name='qemu' type="aio" io='native' cache="none"/> <target dev='sdc' bus='scsi'/> <readonly/> </disk> (In reply to Xujun Ma from comment #3) > It can be reproduced with libvirt,and will displays error as following: > virsh # change-media Server-base sdc > /home/kvm_autotest_root/iso/linux/RHEL7.2-Server-x86_64.iso > error: Failed to complete action update on media > error: internal error: unable to execute QEMU command 'change': aio=native > was specified, but it requires cache.direct=on, which was not specified. > > the configuration of cdrom in xml: > > <disk type='file' device='cdrom'> > <driver name='qemu' type="aio" io='native' cache="none"/> > <target dev='sdc' bus='scsi'/> > <readonly/> > </disk> Can you post the entire domain xml?

Is there a powerpc box running rhel 7 that I can easily log on to, to see if I can reproduce there faster than it takes me to set up one locally?
