KVM on ubuntu
Hey guys,
I'm no Ubuntu Guru, so I want to check that I have this right....
Our documentation says:
--------------------------
On Ubuntu: modify /etc/default/libvirt-bin
Add "-l" to the following line
libvirtd_opts="-d"
so it looks like:
libvirtd_opts="-d -l"
---------------------------
I've found on Ubuntu 16.04 that you seem to need:
/etc/default/libvirt-bin
to have:
libvirtd_opts="-l"
and
/etc/init/libvirt-bin.conf
to have:
env libvirtd_opts="-d -l"
Can anyone confirm/deny this and should it also be this way for Ubuntu 14.04 ?
If so I'll update the documentation...
cheers
Kind regards,

Thanks guys,
😊 I guessed that you were meaning 14.04 Özhan.
@wido are you saying that you need the -l flag in '/etc/default/libvirt-bin' for live migration or only in '/etc/init/libvirt-bin.conf' ?
Kind regards,

Indeed! Mainly the -l flag is important to make libvirtd listen on TCP
sockets which are required for live migration.

In my experience,
/etc/init/libvirt-bin.conf is used for ubuntu 12.04 (add "-d -l", any
change in /etc/default/libvirt-bin has no impact)
/etc/default/libvirt-bin is used for ubuntu 16.04. We use -l . "-d" will
cause libvirt-bin fails to restart. If libvirt-bin fails to restart, please
execute "systemctl stop libvirt-bin.socket" then restart libvirt-bin.
/etc/default/libvirtd is used for ubuntu 17.04 . same as ubuntu 16.04 (-d
is not needed).

Re: KVM on ubuntu

Hi Paul;
Ubuntu 16.04 has systemd installed and it directly controls libvirtd
process so if you add -d to /etc/default/libvirt-bin file libvirtd tries to
control to its self and then you have problem, you could not
stop/start/restart libvirtd service via systemd. Only adding -l flag to
libvirtd_opts is enough for Cloudstack.
We also make no change on /etc/init/libvirt-bin.conf file for 16.04
For Ubuntu 16.04 you need to add both -d and -l flags for
/etc/default/libvirt-bin
file.
Thanks
Özhan
