Re: [Xen-devel] [XenGT][IGVT-g] Device model creation failed

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

What does Qemu log tell you about below error?

 

libxl: error: libxl_dm.c:1531:device_model_spawn_outcome: domain 1 device model: spawn failed (rc=-3)

 

In the meantime, itâd be helpful if you can capture serial console output. If error comes from XenGT driver, there should be some useful information.

 

btw, looks this VTC-1010 is based Baytrail. Please be noted that XenGT formally supports only Core based system. Atom SoC is not the target. We do have a BYT experimental porting (âbyt-experimentâ branch) on github, which is based on old code and not maintained anymore. You may want to try that branch instead.

 

Thanks

Kevin

Subject: [XenGT][IGVT-g] Device model creation failed

 

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

Parsing config from ./a.cfg

WARNING: specifying "tsc_mode" as an integer is deprecated. Please use the named parameter variant. e.g. tsc_mode="default"

WARNING: you seem to be using "kernel" directive to override HVM guest firmware. Ignore that. Use "firmware_override" instead if you really want a non-default firmware

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

Do you have any ideas about this issue?

Thank you.
