Hi,

So I git clone https://github.com/wencongyang/qemu-xen.git

but i only see branch "con-xen-v2" instead of " colo-xen-v2" so I assume I
use just use con-xen-v2.

But then the following step:

in both ~/qemu-colo and ~/qemu-xen

./configure --enable-xen --target-list=x86_64-softmmu
--extra-cflags="-I$path_to_xen_source/tools/include
-I$path_to_xen_source/tools/libxc -I$path_to_xen_source/tools/xenstore"
--extra-ldflags="-L$path_to_xen_source/tools/libxc
-L$path_to_xen_source/tools/xenstore"


I got the following error message:

"ERROR: User requested feature xen
       configure was not able to find it.
       Install xen devel"

I found out the the error came from just simply doing this:

./configure --enable-xen

I am thinking the reason is because I did this step wrong:

"path_to_xen_source=~/xen"

Do I just simply copy and paste the above command into the terminal and
execute?

Thank you!

Victor








Thank you!
