Re: [libvirt-users] Fedora 19/20 new install :Unable to create vcpu cgroup
Hi, I sill need some help. I tried to remove cdrom and USB controllers from qemu xml definition file. It doesn't help. Still same Failed to create chardev when trying to run a Vms that run on my local Fedora 20 computer. Any idea?

Also, please try `virt-builder` tool to create a VM as I noted in my first reply to this thread. -- /kashyap
