ClickOS failed to run on Xen+Ubuntu 14.04.2

[shashibici]

Hi,

Recently, I am trying to make ClickOS run on Xen hypervisor with Ubuntu-14.04-64bits LTS desktop as Dom0. But I cannot work it out.

I have made it work on Debian-7.8-64bits. Seems it runs perfectly on Debian.
Just wondering whether the toolchain and clickos is compatible with Ubuntu? Did you ever make it work on Ubuntu?

A very similar problem is here: cnplab/cosmos#3
I encoutered the same thing on Debian, but I made it work by following the instructions discussed in that issue. It is the "cosmos make DOMLIB=xl" that matters.
For Ubuntu, it did not work.

In Ubuntu, I do exactly the way I did on Debian:

1. Install Ubuntu 14.04 desktop as host.
2. Download Xen-4.4.1 source code, compile and install.
3. Reboot from Ubuntu-Xen-hypervisor with Ubuntu 14.04 as Dom0.
4. Git clickos, toolchain, cosmos, minios.
5. Make toolchain.
6. Make clickos
7. Make cosmos
8. Setup bridges for Xen.
9. xl create /home/work/clickos/minios/config.xen (This point, xl list shows clickos -b----. )
10. /home/work/cosmos/dist/bin/cosmos start $DOMID /home/work/clickos/minios/rule.click (This point, xl list show clickos -b---- .)
11. xl console $DOMID ($DOMID set correctly.)

After that the output is as following:

xl list still shows clickos with status -b----.
