Dear all: I ust installed Fedora16Fedora16 X86_64 on my new machine, and then I ran the commands as follows(ran as root):

yum install qemu-kvm yum install qemu yum install libvirt yum install virt-manager

then I started the libvirtd as follow: /etc/init.d/lbvirtd start

So , it ran well.

However, after a few days , when I ran the command "virt-manager" , it showed as bellow:

it seemed that ti cannot connect the hipervisor.

This list is plain-text only. Your embedded graphic (at least, I'm assuming you attempted to embed a graphic) got eaten by the list server, so we don't know what message you got. Can you paste the actual error message you got? Meanwhile, we have a wiki page for diagnosing common problems. Perhaps your issue is covered by one of the items there; and if not, it would help if you could add a new page with the steps you take in resolving the issue. http://wiki.libvirt.org/page/Troubleshooting

Then I did a little test: I ran the conmand "virsh list" , but it didnot work,either.

Again, knowing the exact output of 'virsh -c qemu:///system list', rather than just saying it didn't work, will help others in diagnosing your issue. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
