I initially had the problem posted here: https://bbs.archlinux.org/viewtopic.php?id=159159
and resolved it as indicated there.
However, a problem I had before (https://bbs.archlinux.org/viewtopic.php?id=157203) has returned.
user/group are set to root/kvm or my_username/kvm in qemu.conf, both have the following result:
virsh # list --all
Id Name State
----------------------------------------------------
- win7imo shut off
virsh # start win7imo
error: Failed to start domain win7imo
error: internal error process exited while connecting to monitor: chardev: opening backend "pty" failed
I am in group kvm.
Help appriciated, thanks in advance.

Check if your user is in the kvm group, if not, re-add your user to the km group.

I double checked, and yes, the user is in group kvm

Ok, found my problem. I don't have a /dev/pty on my host (anymore??). So after removal of the serial device from the guest machine, I could start it again.

I am getting this same issue trying to create a new VM

Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
virsh --connect qemu:///system start Fedora
otherwise, please restart your installation.
My user is also in the kvm group and I don't have a /dev/pty device on the host. I am not defining a serial device for the guest and have no clue how/where the device is coming from.
