<pre>Hi Shi,</pre>
<pre>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:
--oneadmin@omii001$ id root
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),127(libvirtd),36(kvm)
--oneadmin@omii001$ id oneadmin
uid=1002(oneadmin) gid=1003(cloud) groups=1003(cloud),127(libvirtd),36(kvm)
--oneadmin@omii001$ cat /etc/group
libvirtd:x:127:root,oneadmin,cloud
cloud:x:1003:
kvm:x:36:root,oneadmin,cloud
--oneadmin@omii001$ ls -la /var/run/libvirt/
total 20
drwxr-xr-x 4 root root 4096 Nov 17 13:12 .
drwxr-xr-x 16 root root 4096 Nov 17 14:32 ..
srwxrwx--- 1 root libvirtd 0 Nov 17 13:12 libvirt-sock

drwxr-xr-x 2 root root 4096 Nov 17 13:12 network
drwxr-xr-x 2 root root 4096 Sep 11 21:38 qemu
--oneadmin@omii001$ cat /etc/libvirt/libvirtd.conf
unix_sock_rw_perms = "0770"
unix_sock_group = "libvirtd"
I am not sure virsh is connecting in the right way, in fact if try "<i>virsh -c qemu:///system list</i>" 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$virsh -c qemu:///system list
Id Name State
----------------------------------
--oneadmin@ivanoc$virsh -c qemu:///system list
Connecting to uri: qemu:///system

<pre wrap="">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.

<pre wrap="">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
oneadmin@omii001$ chkconfig --list | grep qemu
