[Xen-devel] Problems when creating domU on FastModel Cortex-A15

[XiaoGuang Wang <xjtuwxg@xxxxxxxxx>]

Hi all,

I tried to create domU on FastModel. But it seems to have some problem when I create the domU.

root@dom0:/root# xl create domU-config
Parsing config from domU-config
Failed to unmap pfn:86cf6 rc:-2
Failed to unmap pfn:87aa5 rc:-2
Failed to unmap pfn:86cf6 rc:-2
Failed to unmap pfn:87aa5 rc:-2
Failed to unmap pfn:86cf4 rc:-2
Failed to unmap pfn:86cf3 rc:-2
Daemon running with PID 85
root@dom0:/root# xl list
Name                                        ID   Mem VCPUs    State    Time(s)
Domain-0                                     0   127     1     r-----       6.7
domU                                         1   100     1     --psc-       0.0

DomU is not actually started. After a while, domU will be disappeared from the list.


I made the domU image file by:
# cat arch/arm/boot/zImage xenvm-4.2.dtb > /mnt/root/image

The domU-config file is as follows:
kernel = "/root/image"
memory = 100
name = "domU"
vcpus = 1
disk = [ 'phy:/dev/loop0,xvda,w' ]

And setup loop device like:
$ losetup /dev/loop0 /root/domU.img

So is there something I have to do with the domU kernel configuration file? I just use the same config file as I used in dom0, from: http://xenbits.xen.org/people/sstabellini/config

And if domU is successfully started, where will I see the domU console? (same in dom0 console?)

Thanks!

Xiaoguang
