Hello I've put the root-key on the authorized_key file of all the host, and reboot the cluster, but I've got the same error with the two opcion (virt-manager and virsh). I think that is sth related to the authorization on the libvirtd.conf. This is my conf at all the hosts (see libvirtd.conf attached too)., I'd appreciate a lot if someone can tell me if it right (it's a developer cluster): *unix_sock_group = "libvirtd"* *unix_sock_ro_perms = "0777"* *unix_sock_rw_perms = "0777"* The user radic that execute is member of libvirtd group. Thank you.

Hello Daniel: In the log I found that libvirt coudn't find image file. I solved that, but know I've got: *virsh # migrate scompi1 qemu+ssh://rionegro/system error: Unknown failure * The log on target (rionegro:/var/log/libvirt/qemu/scompi1.log) say: LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 4096 -smp 4 -name scompi1 -uuid 355123af-b683-9fa6-ca31-10506c9ab9da -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/scompi1.monitor,server,nowait -monitor chardev:monitor -boot c -drive file=/home/radic/mvdata/imagenes/scompi1.img,if=ide,index=0,boot=on,format=raw -drive if=ide,media=cdrom,index=2,format=raw -net nic,macaddr=52:54:00:05:d1:2a,vlan=0,model=virtio,name=virtio.0 -net tap,fd=32,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 -parallel none -usb -vnc 127.0.0.1:0 -vga cirrus -incoming tcp:0.0.0.0:49163 char device redirected to /dev/pts/1 *pci_add_option_rom: failed to find romfile "pxe-virtio.bin"* At one forum I've read that it can be solved installing the package kvm-pxe. It's ok? Thank you very much. Marcela. 2011/4/1 Daniel P. Berrange <berrange(a)redhat.com&gt;
