try

disk = [ 'tap:aio:/var/lib/xen/test.img,xvda1,w', 'tap:aio:/var/lib/xen/test.swap,xvda2,w' ]

this does not help

Subject: [Xen-users] blktap howto


hi,

i'm trying move from file: based disk to tap:aio but things don't work

i have centos4 dom0 with centos4 domU
xen 3.0.4-testing changeset:   13138:d401cb96d8a0 self compiled

[root@xen linux-2.6.16.38-xen]# grep XEN_BLKDEV_TAP .config
CONFIG_XEN_BLKDEV_TAP=m

config
disk = [ 'file:/var/lib/xen/test.img,hda1,w', 'file:/var/lib/xen/test.swap,hda2,w' ]
changed to
disk = [ 'tap:aio:/var/lib/xen/test.img,hda1,w', 'tap:aio:/var/lib/xen/test.swap,hda2,w' ]

blktapctrl do nothing

domU cannot start, fail when mounting root

what i'm doing wrong?
i dont have any kernel module for blktap, is this ok?
