Did you get any error messages? The first problem is, that it seems to be a tool to create persisten virtual machines, e.g. virtual servers, but most of the time I only want to boot a live cd, e.g. a Fedora one. But virt-manager seems to demand an virtual HD drive. I only tested it twice or so, but it looked not promising.

What I did so far was creating a new machine with a Fedora Live CD Image and booted it. When I hit the Pause button, it appeared to be pressed, but nothing happened. The machine still responded and the following error appeared on the commandline, where I started virt-manager: ------------- libvir: QEMU error : operation failed: suspend operation failed Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/console.py", line 389, in control_vm_pause self.vm.suspend() File "/usr/share/virt-manager/virtManager/domain.py", line 365, in suspend self.vm.suspend() File "/usr/lib/python2.5/site-packages/libvirt.py", line 350, in suspend if ret == -1: raise libvirtError ('virDomainSuspend() failed', dom=self) libvirt.libvirtError: virDomainSuspend() failed operation failed: suspend operation failed --------------

Then when I shut down the machine and clicked on "run", it did not boot the ISO Image I selected while creating the machine, but only complained that it could not boot from HD (which is true, because I did not install anything to the HD) Then I wanted to delete the machine, but the "Delete" button was still greyed out, even when I shut it down (Imho it should be available all the time and provide a warning that the machine needs to be shut down before it can be deleted). When I closed virt-manager and opened it again, then I was able to delete the machine. But I cannot find a way to add an iso image to the machine or make it boot the iso image I selected at creation time.

Also the network selection seems not to work, when I want to add a network interface, I can choose between virtual and shared device, but both only have an empty list, where I have to select something to be able to click on "Forward".

I guess you cannot help here very much, because it seems to me that virt-manager just needs a lot of coding, to become as userfriendly as VirtualBox is.
