Could not generate persistent MAC address for vunl0_1_1: No such file or directory

[tessem]

Hello anyone. I try to install EVE-NG on KVM.

I have an issue with virtual interfaces in EVE.

If i create cisco dynamips router or switch all work fine. Virtual interface is created and cisco run regularly.

If i add Win or Nix* VM one can't run. Virtual interface is created but in log i see:

Mar 28 09:39:31 eve-ng ovs-vsctl[32701]: ovs|00001|vsctl|INFO|Called as ovs-vsctl del-port vunl0_1_1
Mar 28 09:39:31 eve-ng ovs-vsctl[32701]: ovs|00002|db_ctl_base|ERR|no port named vunl0_1_1
Mar 28 09:39:31 eve-ng systemd-udevd[32716]: Could not generate persistent MAC address for vunl0_1_1: No such file or directory

but

21: vunl0_1_1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 9000 qdisc pfifo_fast state DOWN group default qlen 1000
link/ether 8a:68:88:4d:28:56 brd ff:ff:ff:ff:ff:ff

i try to change in /etc/systemd/network/99-default.link
MACAddressPolicy=persistent
to
MACAddressPolicy=none

It does not resolve problem.

All work fine on hardware installation.


I solve it.
Problem was in OPENSTACK. I have to enable nested virtualization with vmx. There are own config section for libvirt in OpenStack.

in nova.conf have to set

[libvirt]
cpu_mode=host-passthrough

for enable VT-x in guests

I met the same issue without my platform was ESXi, but the error print is same it from /var/log/syslog

the rootcause is I forget enable hardware virtualization
