libvirt_lxc not working in Ubuntu 16.04

Question

I installed libvirt on a fresh install of Ubuntu 16.04 desktop using apt install libvirt-bin. I then created an LXC domain named a.

When I tried virsh -c lxc:/// start a, I saw this error message:

virsh # start a error: Failed to start domain a error: internal error: guest failed to start: libvirt: error : cannot execute binary /usr/libexec/libvirt_lxc: No such file or directory

What did I do wrong?

Answer 1

Resolved. It was an environment problem with the Ubuntu libvirt-bin installation. libvirt looks for files in /usr/libexec, e.g. /usr/libexec/libvirt_lxc when starting a domain. However, /usr/libexec is non-existent even after apt install libvirt-bin.

Here's what I did:

mkdir /usr/libexec ln -s /usr/lib/libvirt/* /usr/libexec

That resolved the problem.
