<tt>Hello Jaime,<br>
<br>
qemu.conf is ok :<span class=""><br>
<br>
# grep -vE '^($|#)' /etc/libvirt/qemu.conf<br>
user = "oneadmin"<br>
group = "oneadmin"<br>
dynamic_ownership = 0<br>
<br></span>
I found that </tt><code><span>:<br>
<br>
- user qemu belongs to group 'kvm', but oneadmin doesn't<br>
- I have no libvirtd group<br>
- /etc/libvirt/libvirtd.conf had listen_tcp=1 commented<br>
- </span></code><code><span>/etc/sysconfig/libvirtd
had </span></code><code><span>LIBVIRTD_ARGS="--listen"
commented<br>
<br>
Can I restart libvirt without affecting running VMs?<br>
<br>
Thanks,<br>
regards,<br>

<div bgcolor="#FFFFFF" text="#000000"> <tt>Hello,<br>
<br>
we are using OpenNebula 4.6.2 under CentOS 6.5.<br>
<br>
We have 2 hosts, one of these has also Sunstone and
exports shared datastores (system, image and file),
named 'localhost'. <br>
We also have another system datastore using the ssh
driver.<br>
<br>
We have an issue with stopping VMs ... from sunstone
gui, powering off a VM on the ssh system datastore and
starting it again works; but stopping (option on menu
that includes undeploy and undeploy hard) deletes the
VM files and when trying to start it again, kvm cannot
find the files (i.e. checkpoint).<br>
