You do not need to be a member of those two groups. You need membership of libvirtd to manage the system-wide libvirtd instance (qemu:///system), and you need membership of kvm to run virtual machines as yourself (qemu:///session). If you're using virt-manager for other purposes, you don't even need to be a member of either.
For intrepid, I'll make sure the error messages are more helpful. I will not, however, be automatically adding users to any of these groups. -- virDomainCreateLinux() failed Timed out while reading console startup output https://bugs.launchpad.net/bugs/187048 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
