Thanks for your interest.
Here are the dir/files permissions for the kvmimages dir:
# ls -ld /home /home/kvmimages /home/kvmimages/* drwxr-xr-x. 4 root root 4096 14 juin 23:05 /home drwxrwxrwx 2 root root 4096 15 juin 09:19 /home/kvmimages -rw-rw-rwx 1 root root 12884901888 14 juin 23:07 /home/kvmimages/eff1.img -rw-rw-rwx 1 root root 12884901888 14 juin 23:11 /home/kvmimages/eff2.img -rw----r-x 1 root root 12887130112 11 juin 15:51 /home/kvmimages/effi.qcow2 -rw-r--r-- 1 root root 4295884800 15 juin 09:19 /home/kvmimages/f20vm -rw-r--r-x 1 qemu qemu 4603248640 12 déc. 2013 /home/kvmimages/Fedora-20-x86_64-DVD.iso
As you can see, all are executabled by others.
Should I chown to qemu? or something else?

Always the same Failed to create chardev.
I do think it's a problem of permission as you said, but on which directory/files? Wherever your disk image is located (/home/kvmimages) QEMU should be able to access it (executable bit for 'others'). For instance, I have these permissions for my home directory where I store VM images:
$ ls -lash / | grep home 4.0K drwxr-xr-x. 7 root root 4.0K Aug 7 2013 home
Permissions on the specific directory where I store VM images (/home/kashyap/vmimages):
$ ls -lash /home/kashyap/ | grep vmimages 4.0K drwxrwxr-x. 2 kashyap kashyap 4.0K Jun 14 21:50 vmimages
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. If I'm parsing you correctly, you've SSHed into the remote machine and running virt-install. Like I said, if QEMU can access your home directory (as I noted above), where you're storing disk images, you shouldn't have any issues.
