If not, could it be considered? There are plans to add support for virtio-scsi - still paravirtualized but providing a pv scsi controller that gives us more features - such as passing scsi commands to luns, allowing more disks per vm etc. > Thanks. > _______________________________________________ > Users mailing list > [email protected] > http://lists.ovirt.org/mailman/listinfo/users _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
