[Qemu-devel] qemu seabios issue with vhost-scsi

2013-05-22 Thread Badari
Hi, While testing vhost-scsi in the current qemu git, ran into an earlier issue with seabios. I had to disable scsi support in seabios to get it working. I was hoping this issue got resolved when vhost-scsi support got merged into qemu. Is this still being worked on ? Thanks, Badari [root ~]#
