Good morning there, I compiled and installed libvirt latest version 1.2.6, previously I have apt-get install libvirt-bin, which should be virsh --version: 0.9.8. after apt-get purge libvirt-bin, I compile the libvirt 1.2.6 and installed it, when configure, I did: ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --with-esx=yes I have compiled qemu and installed too, and make a symbolic link to /usr/bin/qemu-system-x86_64 but my question is even I launch a vm in qemu, $virsh list showed nothing, further more, 1) if I use virtual machine manager, it get connection failiure, due to socket to '/var/run/libvirt/libvirt-sock'; No such file of dirctory. 2). there is missing libvirt-bin under /etc/init.d/, after compile and installed libvirt 1.2.6 3). I tried to start libvirtd daemon, sudo /usr/sbin/libvirtd/start shows "/usr/sbin/libvirtd: unexpected, non-option, command line arguments" 4). I've checked /var/log/libvirt/libvirtd.log which shows cannot find suitable emulator for x86_64 I've stuck here for whole afternoon yesterday, any help or suggestion is highly appreciated !! thanks a lot in advance !
