Hi Osier, >From the actual bug messages like fowllowing Actual results: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/createvol.py", line 191, in _async_vol_create poolobj = self.vol.install(meter=meter) File "/usr/lib/python2.5/site-packages/virtinst/Storage.py", line 893, in install (self.name, str(e))) RuntimeError: Couldn't create storage volume 'virt-stor-dir-bochs.img': '/usr/bin/qemu-img exited with non-zero status 1 and signal 0' It seems that libvirt calls command 'qemu-img' to create a volume of bochs but it failed. So the problem may no matter with Libvirt itself. I am not sure if qemu supports to create a volume of bochs. Or something wrong with QEMU? -- Thanks Harry Wei -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
