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
