[Xen-users] Re: tap:aio VBD Support.
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
( cd xen && ln -sf ../../../xen/include/public/*.h . )
mkdir -p xen/hvm
( cd xen/hvm && ln -sf ../../../../xen/include/public/hvm/*.h . )
