Hi Shi,
I followed your advice and created a symbolic link to /usr/bin/kvm
--oneadmin at 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 at 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 at omii001$ id oneadmin
uid=1002(oneadmin) gid=1003(cloud) groups=1003(cloud),127(libvirtd),36(kvm)
--oneadmin at omii001$ cat /etc/group
libvirtd:x:127:root,oneadmin,cloud
cloud:x:1003:
kvm:x:36:root,oneadmin,cloud
--oneadmin at 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
srwxrwxrwx 1 root libvirtd 0 Nov 17 13:12 libvirt-sock-ro
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 at 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 "/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 at omii001$virsh -c qemu:///system list
Id Name State
----------------------------------
--oneadmin at ivanoc$virsh -c qemu:///system list
Connecting to uri: qemu:///system
Id Name State
