Did you use the right configure flags? > I can't install qemu 1.0 and libvirt 0.9.10 through apt right? Ah, apt - are you on debian or ubuntu? I don't know as much about the versions that those distros are using (I'm personally using Fedora 16, along with the fedora-virt-preview repo, which gives 0.9.10 pre-built). > I assume I > had to get them from source.

There might be someone already shipping a pre-built 0.9.10 apt, but I wouldn't know where to tell you to look, so building from source is the other alternative. If you build from libvirt.git, you can use './autobuild.sh --system' to help set the ./configure options that match with the typical installation directories for at least Fedora, but again, I don't know how that fares with the debian installation layout (and patches are welcome to autobuild.sh for anyone that wants to use it on a debian layout). -- Eric Blake ebl...@redhat.com +1-919-301-3266 <tel:%2B1-919-301-3266> Libvirt virtualization library http://libvirt.org Yeah, I am using Ubuntu 11.10. I was able to uninstall the old libvirt and virsh works again but still getting this when trying to start the vm: testa@testaT4:~$ virsh list Id Name State ---------------------------------------------------- testa@testaT4:~$ virsh version Compiled against library: libvir 0.9.10 Using library: libvir 0.9.10 Using API: QEMU 0.9.10 error: failed to get the hypervisor version error: internal error Cannot find suitable emulator for x86_64 testa@testaT4:~$ virsh -c qemu:///system start Shawn error: Failed to connect socket to '/usr/local/var/run/libvirt/libvirt-sock': No such file or directory I guess you're using a old virsh with new libvirt, you may check your virsh command location, if `which virsh` says '/usr/bin/virsh' and `which libvirtd` says /usr/sbin/libvirtd, and socket is /var/run/libvirt/libvirt-sock not above socket path, it's right. It probably your virsh command path is /usr/local/bin/virsh, and your socket path is /var/run/libvirt/libvirt-sock now, if so, you may explicitly specify /usr/bin/virsh or clean up your dirty environment then directly run virsh instead of a absolute path. Good Luck! Alex error: failed to connect to the hypervisor testa@testaT4:~$ Thanks again for helping me out! I ended up starting over and reinstalled Ubuntu 11.10. I removed the exiting kvm and downloaded qemu-kvm-1.0.tar.gz and built it from source out of my Downloads directory. I then did the same thing with libvirt 0.9.10. Virsh works but still when I do the version it still says: error: failed to get the hypervisor version error: internal error Cannot find suitable emulator for x86_64 I also can't seem to start libvirtd and it is not located in /etc/init.d Sorry for the noob question but how do I configure and build qemu-kvm and libvirt so that they are all installed in the correct places? Is there a specific flag I need to use or do I need to install them from a specific directory? It looks like the files and being put all over the place. Some are in /etc and some are in /usr/local/etc. If I can get everything to install in the correct spots I should be good I would hope. Thanks!
