<pre>Hi Shi,
I changed the name of the Ethernet device inside of the configuration file as you suggest, using br0 instead of eth0, but it didn't help.
Now, I have a doubt:
if I use the hook scripts (the ones in one/share/hooks/ in the last opennebula release) (as actually I'm trying to do)
have I to set-up a bridged network? I mean more than what is written here <span
class="moz-txt-citetags"></span><a class="moz-txt-link-freetext"
href="http://www.opennebula.org/doku.php?id=documentation:rel1.4:nm">http://www.opennebula.org/doku.php?id=documentation:rel1.4:nm</a>
<span class="moz-txt-citetags"></span>or I have only to change some of the setups, that I have already done following the guide? I wouldn't interferer with the scripts changing the network topology.
Many tanks,
Gianni.

<pre wrap="">My pleasure.
I think the problem is that you have to setup brdiged network on the
host properlly.
Instead of using eth0 as the network device in the VM, you should use br0.
You can google how to setup bridged network for virtualization for
your Linux distribution.
Hope this helps.

Thank you Fernando for the information,
Anyway I forget to say I have already changed that lines.

I would try to add/uncomment the following lines in the file /etc/libvirt/libvirtd.conf:
auth_unix_ro = "none"

Why? I had to do it in my Fedora 11, and I think you are using Scientific Linux, which must be similar to Fedora.
Hope this helps.

<pre wrap="">Hi Shi,
I followed your advice and created a symbolic link to /usr/bin/kvm
--oneadmin@omii001$ ln -s /usr/libexec/qemu-kvm /usr/bin/kvm
So I was able to solve that problem, thank you very much.
Anyway now I have another issue when I try do deploy my VM:
libvir: QEMU error :internal error Failed to add tap interface 'vnet%d' to
bridge 'eth0' : Permission denied
This are the settings on omii001 host that I should be related with the
issue:

unix_sock_rw_perms = "0770"
unix_sock_group = "libvirtd"
I am not sure virsh is connecting in the right way, in fact if try "virsh -c
qemu:///system list" in the omii001 host
I obtain a different output to the one from another host (that actually
works), maybe have I to set the connection uri?
--oneadmin@omii001$virsh -c qemu:///system list

Maybe kvm is not located at /usr/bin/kvm in your host distribution?
A quick and dirty way might be to create a symbolic link. Not sure if
it would help.

Hi all,
I configured an OpenNebula (v 1.3.80) front-end in my pc "solaris" (Ubuntu
9.04) and installed a cluster node "omii001" (Scientific Linux CERN SLC
release 2.6.18-164.6.1.el5 x86_64).
I need to access my VM through ssh, so I used the Bridged networking
("shared physical device") following this instructions:
<a class="moz-txt-link-freetext" href="http://www.opennebula.org/doku.php?id=documentation:rel1.4:nm">http://www.opennebula.org/doku.php?id=documentation:rel1.4:nm</a>
And I used the kvm-hook-script taken from v. 1.3.85
When I try do deploy my VM I have a failure.
from the log file seems that I have a problem with KVM configuration:
"Cannot find QEMU binary /usr/bin/kvm: No such file or directory"
I'm not sure my kvm installation was done properly, so maybe is my fault..
anyway I follow the steps in the documentation and I can't find a
solution.
Here some information about my configuration:
I should have the kvm module loaded on my node:
oneadmin@omii001$/sbin/lsmod | grep kvm
kvm_intel 86248 0
kvm 223264 2 ksm,kvm_intel
But I have no kvm service running... (Is that my problem?)
oneadmin@omii001$ chkconfig --list | grep kvm
oneadmin@omii001$ chkconfig --list | grep libvirtd
libvirtd 0:off 1:off 2:off 3:on 4:on 5:on 6:off
