Wrong permissions on /dev/kvm after installation of qemu

Reproducible: Always

Actual Results:  
kvm@deathstar ~ $ qemu-kvm 
Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied
No accelerator found!
root@deathstar # ls -l /dev/kvm 
crw------- 1 root root 10, 232 Dec 17 18:09 /dev/kvm


Expected Results:  
kvm@deathstar ~ $ qemu-kvm

You need to run udevadm trigger && udevadm settle, this can not be reliably run by the ebuild and there's an einfo to run this.

[Comment 2 Doug Goldstein (RETIRED) 2013-01-21 20:36:59 UTC]

Either way, I recommend going to 1.2.2-r2.

I don't think so ...

# grep udevadm qemu-1.1.2-r2.ebuild  | wc -l
