RE: [Xen-users] Re: tap:aio VBD Support.

["Dan Kendall" <Dan.Kendall@xxxxxxxxxx>]

I've just repeated the install using xen-unstable distro and the disk images 
now appear to be working using tap:aio.  Will v3.0.3 support the blktap method? 
 Using an unstable branch for serious work does not seem especially inviting.

cheers,
Dan

I'm having the same problem, decided i would test it out.  I built my 
xen/tools/dom0/domU from source using 
http://tx.downloads.xensource.com/xen-3.0-testing.hg changeset 9763.

I have backend block drive set as a module and it's loaded..

[root@localhost /]# lsmod
Module                  Size  Used by
xenblk                 20816  0


but when trying to start a domU i get the following error..

[root@localhost vps1]# xm create -c vpsconfig
Using config file "vpsconfig".
Error: Device 2049 (vbd) could not be connected. Hotplug scripts not 
working.

I've been reading around and this blktap code sounds fairly new?  Does 
testing not have working code for it?  When trying to build blktap in tools 
i get the following

[root@localhost tools]# cd blktap/
[root@localhost blktap]# make
mkdir -p xen

mkdir -p xen/hvm
