I'm running Xen 4.6.1 with Alpine Linux 3.3.3 in dom0. In a HVM domU
with vga="qxl", Xorg will segfault instantly if tried started. Multiple
Linux distros have been tested and Xorg segfaults in all.
Attached are a full backtrace from domU generated by Xorg, and a
assembler dump of function 'sse2_blt'.
According to Xen IRC channel, the cause could be a bug in the x86
instruction emulator related to SSE.
Core was generated by `/usr/bin/X -nolisten tcp :0 -auth
/tmp/serverauth.J8ecNHkUxO'.
Program terminated with signal SIGSEGV, Segmentation fault.
