Hello,


Hello,

I have seen this e-mail posted a couple of times. I will only answer to this 
e-mail.

First of all, I would recommend to CC people that might be interested with the 
topic, so the thread get flagged in our inbox. Otherwise, you may have to wait 
longer for an answer. Don't worry if you don't get the right people, they will 
CC relevant people.




  * We are using XEN-4.12.


Xen 4.12 is not yet released. So what is the commit used?


  * Linux 4.14 as dom0 and Linux4.19 as domU.


Please provide more details such as the hardware you use, the guest 
configuration, the full log (Xen + Dom0 + DomU).




When domU is create getting below log.
qemu-system-i38[3478]: unhandled level 1 translation fault (11) at 0x0010, 
esr 0x9205, in libxengnttab.so.1.2[7faf9cd000+3000]


What PV drivers are you using?



Also  p2m is failing .
(XEN) p2m.c:1456: d2v4: gvirt_to_maddr failed va=0x80001dfa1090 flags=0x1 
par=0x80


I think this is unrelated, this is more likely related to KPTI and a known issue 
that needs to be fixed. It is in my TODO list, not sure when it is going to be 
resolved though. Any help would be welcomed here.


Best regards,
