I reinstalled the vdsm(4.9.6) in CentOS 6.,
The problem of "pty failed" disappeared.
But another problem appeared.
I create a DC and the type is "Local on host"
I add the host and create a Local storage domain to the DC.
I create VM with default values, but I failed to run the vm with
follow error message:

error : virNetClientProgramDispatchError:170 : internal error Process
exited while reading console log output: char device redirected to
/dev/pts/4
qemu-kvm: -drive
