Dear ALL!

 

qcow2 format disk works well with xen for most cases;

BUT if using coroutine function such as block-stream, the qemu process crashed!

And we can found following msg from cmd dmesg

 

qemu-system-i38[20514]: segfault at 60 ip 00007f2b60dc879a sp 00007ffffcc2f000 error 4 in qemu-system-i386[7f2b60cdf000+529000]

 

Any suggestion?

 

----------------

XEN version： xen 4.4.0-rc3

guest os : centos 6.4
