A good thing to try is whether 'virsh -c qemu:///system list --all' shows anything; debugging a command-line test can be easier than debugging a gui not listing anything. > > I'm sure I must be doing something wrong but cannot figure out what.

When your posting expires, someone revisiting this thread in the mail list archives will have no idea what you were seeing. So I'm reproducing it here: > ./configure --target-list=x86_64-linux-user --enable-kvm --sysconfdir=/etc/libvirt --localstatedir=/var; This is not the same set of configure options as what is used by the rpm package shipped in CentOS. As a result, if you have any mismatch between the distro build and your self-build, things tend not to connect to the right server. Libvirt's autogen.sh has a --system flag that sets up the following configure arguments, which tends to work better out-of-the-box for replacing a Fedora-based distro build with a self-build: if test "x$1" = "x--system"; then shift prefix=/usr libdir=$prefix/lib sysconfdir=/etc localstatedir=/var if [ -d /usr/lib64 ]; then libdir=$prefix/lib64 fi EXTRA_ARGS="--prefix=$prefix --sysconfdir=$sysconfdir --localstatedir=$localstatedir --libdir=$libdir" > > [root@10-3-1-35 qemu_images]# lsmod > Module Size Used by > kvm_amd 41702 0 > kvm 316506 1 kvm_amd > > [root@10-3-1-35 qemu_images]# ls -l /dev/kvm > crw-rw----. 1 root root 10, 232 Jun 16 09:13 /dev/kvm This looks fishy; /dev/kvm should be 0666, not 0660. > > [root@10-3-1-35 qemu-1.7.1]# which qemu-x86_64 > /usr/local/bin/qemu-x86_64 Again, an issue of self-built binaries not being in the same location as the distro defaults, so I'm not sure if you have configured everything to work well with this location. > > [root@10-3-1-35 qemu_images]# qemu-x86_64 > usage: qemu-x86_64 [options] program [arguments...] > Linux CPU emulator (compiled for x86_64 emulation) > > [root@10-3-1-35 qemu-1.7.1]# cat /etc/redhat-release > CentOS release 6.5 (Final) -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
