Re: [Users] Unable to run VM with ”opening backend ‘pyt’ failed”

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 file=/rhev/data-center/2d7df94d-738d-4d7d-97a4-dd5027a4bf25/d3267b58-cbbd-4e6e-8685-8acd152d49a1/images/7e1011e0-d0ac-4c1f-bd09-a19e450c3259/9c728c1d-762e-4670-9076-9ca5a37b6354,if=none,id=drive-virtio-disk0,format=raw,serial=7e1011e0-d0ac-4c1f-bd09-a19e450c3259,cache=none,werror=stop,rerror=stop,aio=threads: could not open disk image /rhev/data-center/2d7df94d-738d-4d7d-97a4-dd5027a4bf25/d3267b58-cbbd-4e6e-8685-8acd152d49a1/images/7e1011e0-d0ac-4c1f-bd09-a19e450c3259/9c728c1d-762e-4670-9076-9ca5a37b6354: Permission denied Best wishes, Xuejie Chen 2012/7/12 Dan Kenigsberg <danken(a)redhat.com&gt;: > On Wed, Jul 11, 2012 at 05:23:18PM +0800, xuejie chen wrote: >> Hi everyone, >> >> I installed the vdsm(4.9.6) in CentOS 6, > > > >> the libvirt version is 0.9.4 and the qemu-kvm's version is 0.12.1.2. >> I create a VM with all default values, >> But, when I run the vm, it returns failure with the follow error >> message in WebAdmin. >> "internal error Process exited while reading console log output: >> chardev: opening backend "pty" failed. >> >> There are logs file in attachment >> >> If you want other info, please tell me. >> >> Best wishes, >> Xuejie Chen
