Hi Xen-ARM,

You will find it on "git://xenbits.xen.org/people/jm77ryu/linux-xen.git"


extract root filesytem contents as following(This requires the root
privilege)
sudo tar -xvpf rootfs_dom0.tar.bz2.

By the way do you have a working Xen-ARM Code?
If so, please mention it, I mean the version/commit etc..

Alongside the Fast Models download you can also download a "3rd party
IP" pack which includes a Linux rootfs. On my system this ended up
installed as
FastModels/FastModelsPortfolio_7.0/images/RTSM_VE_Linux/filesystems/armv5t_min_VE_V7.image

Thanks, that's helpful.

Can I not attach this image directly to the emulator as MMC card? E.g.
my parameters contain

-C motherboard.mmc.p_mmc_file=~/ARM/FastModelsPortfolio_7.0/images/RTSM_VE_Linux/filesystems/armv5t_min_VE_V7.image

When Dom0 boots I get the following error:

Any ideas?

BTW, I've added xen-devel@. xen-arm list is more for the Xen PV ARM port
so I've bcc'd it.

That basically what I do but I use the full path and not ~ since I
wasn't sure model_shell interprets "~". I guess based on this evidence
it does...

So it looks like the FS was mounted OK but for some reason /sbin/init
didn't run. Maybe try adding "init=/bin/sh" to your command line as a
first test?

Does "-C cluster.cpu0.vfp-enable_at_reset=1" help?
