Hi, Thanks Kashyap for your answer. I am trying to give more data: virt-install invokation: # virt-install --name eff1 --disk /home/kvmimages/eff1.img --cdrom /home/kvmimages/Fedora-20-x86_64-DVD.iso --memory 4096 WARNING CDROM media does not print to the text console by default, so you likely will not see text install output.

ERROR internal error: process exited while connecting to monitor: Failed to create chardev L'installation du domaine ne semble pas s'être terminée avec succès. Si c'est bon, vous pouvez démarrer le domaine en lançant : virsh --connect qemu:///system start f20vm sinon, recommencez l'installation. Always the same Failed to create chardev. I do think it's a problem of permission as you said, but on which directory/files? I am connected as root on my remote server, as simple user on my local computer. Both are running F20. When I create/run a F20 VM on my local computer, it's OK. I have verified rpm versions, seem OK. I have rsynced /etc/libvirt dir from local computer to remote server. It works on my local like on yours,but not on my remote. I need the remote to run VMs. Thanks for your help. Patrick Le 15/06/2014 09:51, Kashyap Chamarthy a écrit :

When tyring to create new VM with virt-install, I am getting:

Début d'installation... ERROR internal error: process exited while connecting to monitor: Failed to create chardev I just tested on my Fedora-20 machine, trying to boot a Fedora-19 VM it works for me:
$ qemu-img create -f qcow2 -o preallocation=metadata \ /export/vmimages/f19vm 4G
$ virt-install --name f19vm --disk /export/vmimages/f19vm \ --cdrom /export/Fedora-Live-Desktop-x86_64-19-1.iso \ --memory 2048

But, I should mention that I'm using virt packages from Rawhide:
$ rpm -q virt-install libvirt-daemon-kvm qemu-system-x86 virt-install-1.0.1-3.fc21.noarch libvirt-daemon-kvm-1.2.6-1.fc20.x86_64 qemu-system-x86-2.0.0-1.fc21.x86_64
When trying to run with virt-manager a VM created on another F20 server:

What is this chardev error? Ensure you have correct permissions to allow QEMU to access disk images in your $HOME directory:
$ chmod o+rx $HOME
I guess that should resolve it.
