[Xen-users] blktap on debian

[Jonathan Selander <jonathan@xxxxxxxxx>]

Hello,

I run xen 3.0.3 on Debian 4.0 and so far I've got 5 guests. I've read in 
the user documentation that it's better to use blktap than loopback, 
because of performance reasons, so i decided to switch to it. However, 
the root device isn't found by the guest system. I read something about 
CONFIG_XEN_BLKDEV_TAP being needed in the kernel for it to work, is that 
true? I have
CONFIG_XEN_BLKDEV_BACKEND=y
# CONFIG_XEN_BLKDEV_TAP is not set
CONFIG_XEN_BLKDEV_FRONTEND=y

The guest config disk line looks like this:

disk    = [ 'tap:aio:/var/xen/domains/ac/disk.img,sda1,w', 
'tap:aio:/var/xen/domains/ac/swap.img,sda2,w' ]
/Jonathan
