[libvirt-users] libvirtError: internal error Domain mytest didn't show up

Hi All, I am new using libvirt. I kept on getting the following error when I try to start my VM. Can anyone give me any suggestion on what could went wrong? Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup self.vm.create() File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Domain mytest didn't show up Thanks, David
