Public bug reported: When trying to use kvm, in particular creating VM with virt-manager, i get in the GUI the error message "Error:No hypervisor options were found for this connection."
When looking into /var/log/libvirt/libvirtd.log, I see info : libvirt version: 1.2.2 error : virCommandWait:2399 : internal error: Child process (LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin /usr/bin/qemu-system-i386 -help) unexpected exit status 127: /usr/bin/qemu-system-i386: symbol lookup error: /usr/bin/qemu-system-i386: undefined symbol: libusb_get_port_numbers (see attachment for more details) when trying to identify the libusb version, I get: > ls -la $(ldd /usr/bin/qemu-system-x86_64 | grep usb) lrwxrwxrwx 1 root root 19 May 6 2014 /lib/libusb-1.0.so.0 -> libusb-1.0.so.0.1.0 lrwxrwxrwx 1 root root 26 Jan 3 2014 /usr/lib/x86_64-linux-gnu/libusbredirparser.so.1 -> libusbredirparser.so.1.0.0 >apt-cache policy libusb-1.0-0 libusb-1.0-0: Installed: 2:1.0.17-1ubuntu2 Candidate: 2:1.0.17-1ubuntu2 Version table: *** 2:1.0.17-1ubuntu2 0 500 http://ch.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status I got the same with an Ubuntu Server 14.04LTS.
