Xen project Mailing List

Hello!

We are going to use XenGT on Intel Atom based board(VTC-1010, with 4GB RAM).

For this purpose we use next repos:

xen - https://github.com/01org/Igvtg-xen

dom0 (ubuntu linux, 1024MB or 2048MB ) - https://github.com/01org/Igvtg-kernel

domU (android-x86, rest memory excluding xen heap, xen, about 1.7GB RAM ) - same kernel, with some config changes

Guest domain are going to be started in HVM mode.

We follow iGVT-g setup guide (https://github.com/01org/Igvtg-kernel/blob/2015q3-3.18.0/iGVT-g_Setup_Guide.txt) and successfully setup dom0 with iGVT.

But, when we are going to start domU (with enabled vgt=1 switch) domain creation failed with follow log:

vtc@vtc-VTC1010:~$ sudo xl -vvv create -c ./a.cfg

Without this flag - are all ok, domain created and running normally.

Do you have any ideas about this issue?

Thank you.
