Is the logfile informativ for you? Marko Btw, on my Centos6 Boxes all is running like a charme. Am 16.01.2012 18:58, schrieb Michal Privoznik:

Hello to the list at first - i am first time here.

i setup on my gentoo box libvirt and virt-manager. when i fireup virt-manager all seems okay. when i want to create a new virtual machine it seems all okay, until the step when i want to add an iso image to the cdrom. i notcied that i cant choose to connect cdrom, also the network is not found.

i can post error codes from log when needed, just wanted to ask, if someone here had same behaviour and a solution for it.

Hi Marko,

what USE flags is your libvirt compiled with? I personally use:

debug elibc_glibc json libvirtd lxc macvtap nfs nls numa pcap policykit python qemu sasl udev virt-network

What are the error messages in libvirt log?
