The setup script in Dom0 probably can't work.
Could you execute DPDK application on Dom0 as follows:
1. insmod igb_uio.ko
2. insmod rte_dom0_mm.ko
Before compiling DPDK, you should set CONFIG_RTE_LIBRTE_XEN_DOM0=y
(#
#Compile Xen domain0 support
#
CONFIG_RTE_LIBRTE_XEN_DOM0=y
)
3. echo 2048 > /sys/kernel/mm/dom0-mm/memsize-mB/mem_size
4. start DPDK application with --xen-dom0 option.
./testpmd -c f -n 3 --xen-dom0 -- -i --portmask=0x3
For more details how use DPDK application on Dom0, please look at DPDK Getting Start Guide document .

Hi,
New to the dpdk and just downloaded 1.7. I attempting to execute the test application (17) in Dom0 through the setup script.
It hangs during or just after setting up memory. I know I'm doing something wrong, I just can't quickly figure out it is.. need some help !!
I have UIO and KNI modules loaded and 64 pages NUMA shared memory. (I also tried 64 pages non-numa with the same result.)
See:
Option: 17
Enter hex bitmask of cores to execute test app on
Example: to execute app on cores 0 to 7, enter 0xff
bitmask: 0x01
Launching app

Using debian jessie 3.14-1-amd64 #1 SMP Debian 3.14.4-1 (2014-05-13) x86_64 GNU/Linux with XEN 4.3.0
Any suggestions ?
