When creating a vm with a bridge network interface I get this error:

I also get the error when trying to attach the nic to an existing vm.
OpenNebula needs to be able to use
sudo without a password in order to manage some resources like networks, you can find more info here: http://docs.opennebula.org/5.8/integration/references/compile.html?configure-sudo-for-oneadmin#configure-sudo-for-oneadmin
So can you try to provide
sudo permission passwordless and try again?
You seem to be right. I initially had this sudoers file for the oneadmin user:
Defaults:oneadmin secure_path = /sbin:/bin:/usr/sbin:/usr/bin
Cmnd_Alias ONE_MISC = /sbin/mkfs, /bin/sync, /sbin/mkswap
Cmnd_Alias ONE_NET = /sbin/brctl, /sbin/ebtables, /sbin/iptables, /sbin/ip6tables, /sbin/ip, /sbin/ipset, /usr/bin/arping
Cmnd_Alias ONE_LVM = /sbin/lvcreate, /sbin/lvremove, /sbin/lvs, /sbin/vgdisplay, /sbin/lvchange, /sbin/lvscan, /sbin/lvextend
Cmnd_Alias ONE_ISCSI = /usr/bin/iscsiadm, /usr/sbin/tgt-admin, /usr/sbin/tgtadm
Cmnd_Alias ONE_OVS = /usr/bin/ovs-ofctl, /usr/bin/ovs-vsctl
Cmnd_Alias ONE_XEN = /usr/sbin/xentop, /usr/sbin/xl, /usr/sbin/xm
Cmnd_Alias ONE_CEPH = /usr/bin/rbd
Cmnd_Alias ONE_MARKET = /usr/lib/one/sh/create_container_image.sh
Cmnd_Alias ONE_HA = /bin/systemctl start opennebula-flow, /bin/systemctl stop opennebula-flow, /bin/systemctl start opennebula-gate, /bin/systemctl stop opennebula-gate, /usr/sbin/service opennebula-flow start, /usr/sbin/service opennebula-flow stop, /usr/sbin/service opennebula-gate start, /usr/sbin/service opennebula-gate stop
oneadmin ALL=(ALL) NOPASSWD: ONE_MISC, ONE_NET, ONE_LVM, ONE_ISCSI, ONE_OVS, ONE_XEN, ONE_CEPH, ONE_MARKET, ONE_HA
To test if this was the issue i changed it to
oneadmin ALL = (ALL) NOPASSWD:ALL
And the virt did deploy (aside from needing the bridge-utils package still). Can you tell if there is anything missing from my sudoers file that might be causing this?
Disregard my last post. It looks like all I needed was to install bridge-utils. For some reason I wasn’t getting a good error message about this until I changed the sudoers file.
So, is it working fine now? after changing the sudoers file and installing bridge-utils?
The sudoers file didn’t actually need to be changed. I tried on a different node that was still using the stock sudoers file and it worked after installing bridge-utils.
