<div>Hello Valentin,<br>
<br>
Apparently, when creating a VM as a regular user, the only group
that is taken into account is the one that appears as 'gid'
(oneadmin in this case). So what I did to solve the problem was to
change the owner of /dev/kvm to root.oneadmin.<br>

<br>
I have recently setup OpenNebula 3.6 on 2 Debian Squeeze boxes.
Both machines function as hosts, one of them as frontend.<br>
I have followed the OpenNebula documentation [1] to setup the KVM
driver on the hosts.<br>
<br>
### Host A<br>
<br>
# kvm --version<br>
QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c)
2003-2008 Fabrice Bellard<br>
<br>
# virsh --version<br>
0.8.3<br>
<br>
# grep -vE '^($|#)' /etc/libvirt/qemu.conf<br>
user = "oneadmin"<br>
group = "oneadmin"<br>
dynamic_ownership = 0<br>
<br>
# id oneadmin<br>
uid=1001(oneadmin) gid=1001(oneadmin)
groups=1001(oneadmin),106(kvm),108(libvirt)<br>
<br>
# ls -al /dev/kvm<br>
crw-rw---- 1 root kvm 10, 232 Jul 25 11:23 /dev/kvm<br>
<br>
### Host B<br>
<br>
# kvm --version<br>
QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c)
2003-2008 Fabrice Bellard<br>
<br>
# virsh --version<br>
0.8.3<br>
<br>
# grep -vE '^($|#)' /etc/libvirt/qemu.conf<br>
user = "oneadmin"<br>
group = "oneadmin"<br>
dynamic_ownership = 0<br>
<br>
# id oneadmin <br>
uid=1001(oneadmin) gid=1001(oneadmin)
groups=1001(oneadmin),106(kvm),108(libvirt)<br>
<br>
# ls -al /dev/kvm<br>
crw-rw---- 1 root kvm 10, 232 Jul 25 11:23 /dev/kvm<br>
<br>
Doesn't matter on which host the VM gets deployed, the error is
the same. The error follows:<br>
<br>

open /dev/kvm: Permission denied<br>
Could not initialize KVM, will disable KVM support<br>
<br>
I don't have AppArmor installed or any other tool of this kind.
It's just a stock Debian Squeeze install. OpenNebula was compiled
on another machine and installed on Host A which is the frontend.
<br>
<br>
Does anyone of you have any idea about this error? I have Googled
around but could not find any answer. Everything seems correct as
per OpenNebula KVM documentation [1]. <br>
<br>
Thank you for your time invested in reading this email. Cheers and
Goodwill,<br>
