radvd is only built into libvirt if it is found during configure time; however, I don't see any BuildRequires on radvd in the specfile. Perhaps that's the issue; I'm pursuing that idea right now...

Description of problem: libvirt say radvd not installed but radvd is installed already Version-Release number of selected component (if applicable): libvirt-0.8.7-14.el6.x86_64 qemu-kvm-0.12.1.2-2.152.el6.x86_64 kernel-2.6.32-120.el6.x86_64 radvd-1.6-1.el6.x86_64 How reproducible: Everytimes Steps to Reproduce: 1. install radvd # yum install radvd ... Installed: radvd.x86_64 0:1.6-1.el6 # rpm -qa radvd radvd-1.6-1.el6.x86_64 2. define a network supporting ipv6 # virsh net-define ipv6net.xml Network ipv6net defined from ipv6net.xml # cat ipv6net.xml <network> <name>ipv6net</name> <forward mode='nat'/> <bridge name='virbr1' stp='on' delay='0' /> <ip address='192.168.100.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.100.2' end='192.168.100.254' /> </dhcp> </ip> <ip family='ipv6' address='2002:db8:ac10:fe01::1' prefix='64'> </ip> </network> 3. start the network # virsh net-start ipv6net error: Failed to start network ipv6net error: Cannot find radvd - Possibly the package isn't installed: No such file or directory Actual results: After step 3, libvirt prompt error. Expected results: After step 3, the network should be started successfully. Additional info:
