I know QEMU supports that, but even those who implememted it told me it was rather redundant & a historical accident because they did not want to rename the existing 'werror' attribute when they added the 'rerror' bit. So unless someone has a compelling reason for them to be separate I think we can have a single policy. If we follow the style of the <on_reboot> <on_poweroff> elements we'd have something like <on_error>stop</on_error> My only other thought would be to do it as an attribute on the existing <driver> element in disks, where we have disk format & cache mode already Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
