Hi all,

I have a strange problem with qemu img disks allocated in a nfs share on a CentOS 6.4 host. Every time when I try to start a vm this error appears:

char device redirected to /dev/pts/1 qemu-kvm: -drive

file=/data/vmachines/win2k12adsrv/win2k12vol01.img,if=none,id=drive-virtio-disk0,format=qcow2,cache=none:

...

could not open disk image /data/vmachines/win2k12adsrv/win2k12vol01.img: Permission denied

Obviously, qemu disk exists:

[root@c64kvm qemu]# ls -la /data/vmachines/win2k12adsrv/win2k12vol01.img -rw-r--r-- 1 root root 262144 Mar 16 16:11 /data/vmachines/win2k12adsrv/win2k12vol01.img

If I change this qemu disk stored in a nfs share by another stored on local disk, all works ok.

Mount permissions in this kvm host:

sansrv:/ on /exports type nfs4

(rw,rsize=32768,wsize=32768,hard,intr,addr=172.25.60.1,clientaddr=172.25.60.2)

...

and selinux is disabled ... Any idea??

Ok, problem fixed. I've edited the "/etc/libvirt/qemu.conf" file and add the lines:

user = "root" group = "root"

Not a wise idea.

default is to execute as a qemu user ...

Why not fiddle with group ownership and make it so the qemu user will suffice.
