Vm won't start with vgt=1 i3-4130

hello... i am looking to get xengt running but i cant start it... got this in dmesg

which platform are you using? XenGT only supports HSW formally now.

what do u mean by HSW? i am using h81 and i3 4130... haswell?

in pdf guide it says only 4th gen intel processor is requirment?

i changed source devtable.c or smth to include my chip number... now it almost works...

i tried in ubuntu 12.04 and when i enable VGT=1 this happens.... but i cant get screen on output, only brief windows green loading bar / or 0x0000003B BSOD on SDL or VNC,.... nothing on native screen.

thx

here is dmesg:

yes, it’s Haswell the 4th processor.

Looks your box is not included in current device list, so adding your device ID is right way to go, but it also means not validated so some trouble may be caused by hardware difference. Better to find a platform with device ID in existing list.

I didn’t see below log in your full log in another mail, so not sure whether it has all the information there. By default a new VM is in the background after it’s created. So it may already boot but you didn’t note it. One way is to add a boot option “hvm_boot_foreground”, or use sysfs control interface to switch foreground/background VM. You can check setup guide for detail.

thx for response... i have been struggling for 2 days...yeah... i tried with “hvm_boot_foreground”... or sysfs .... it says display not ready. and in xl list it says that vm is blocked. same on 12.04 and 14.04

here is full dmesg... http://paste.ubuntu.com/8315157/ (starting vm is at the end of the log, its spammed with bridge goin up down)

to me this looks strange:

[ 3.230753] vGT warning:(vgt_emulate_read:351) vGT: untracked MMIO read: vm_id(0), offset=0x651b4,len=4, val=0x0!!! and [ 1552.475228] vGT: write to MSI capa(92) with val (0)

so it only depends on processor/gpu? not mbo? still can't belive that my i3 is not on the list lol

what processor do u suggest that works? i am looking for cheap desktop one... thx again.

[slis]

i just got 4770k and i got same problem... so it's me... or smth is missing in pdf

sorry to bother you

[l1viathan]

Hi Slis, did you copy vgt_mgr to your /usr/bin, as well as copy vgt.rules to /etc/udev/rules.d/ ?

Thanks, Jike

Hi, i think i did... i installed it twice (12.04 and 14.04), now i go 3rd time with graphic stack on 12.04. i'll report back later when it's done. thx

btw there is error in pdf at building kernel last line "cp vgt_mgt /usr/bin" it should be "cp vgt_mgr /usr/bin"

and program "bc" is missing form kernel build deps

[slis]

WORKING now :) i think keymap was problem.. now i go do some tests :P

thank you

one more question... if i want use 2 vm's with 2 monitors, i should use indirect mode? and write monitor.conf for each vm with specific output port? is that even possible? using 2 vms at same time on 2 monitors?

[slis]

I can confirm it works only with i7 4770k, but NOT with i3 4130 (0x041e id added to devtable.h)...

With i3 there is no sdl bios screen, only green "safe mode" windows loading, then black screen with only windows arrow on vnc or bsod 0x00000003B.

Here is full dmesg from i3 http://paste.ubuntu.com/8320970/

but if i can't use 2 separate vm's on 2 monitors at same time, my setup is doomed anyway :)

[l1viathan]

Hi Slis:

"cp vgt_mgt /usr/bin" it should be "cp vgt_mgr /usr/bin"

Thanks for reporting this! I fixed that doc and update the repo :)
