Re: [libvirt] Fail to import available VM image



Hi Jun,
I assume you haven't changed libvirt default URI, it may be a issue,
I want to know whether it works for you if you explicitly specify 
--connect qemu:///system with virt-install? I think a root reason
probably is your disk image location, the log said it can't find 
storage volume, if you put img.winp under the /var/lib/libvirt/images, 
then give a disk absolute path to virt-install, Does it work for you?

Regards,
Alex

yes, below is the log content.

also, one thing i dont understand: why it says "Hypervisor name is
'vbox'" in the log? i dont specify any hypervisor name in my command,
and i want to use KVM for my image.

thanks.
