After make finishes I have compiled 1.2.0 libvirt in the source tree, and if I

//Using API: QEMU 1.2.0//
//Running hypervisor: QEMU 1.5.0/
(/note that now I need to run virsh with sudo, I don't know exactly why/)
When run as root, virsh connects to the system libvirt daemon by default (URI
qemu:///system). As a non-privileged user, qemu:///session is used and the
daemon is run as the user.
See http://libvirt.org/uri.html#URI_qemu
Based on this, if I execute regular 1.1.1 'virsh uri' as a non-root I
would read qemu:///session, but instead I get qemu:///system in my computer.
So far, so good. I guess that, with --system flag, 1.2.0 custom libvirt uses
config files from standard directories such as /etc/libvirt/libvirtd.conf, and
if I used a custom directory instead, I would have to redefine my VMs, am I right?
Problems come when I want to use custom 1.2.0 daemon. If I execute "sudo
service libvirt-bin stop" followed by "./daemon/libvirtd -d", then custom
virsh gives me this error:
/error: failed to connect to the hypervisor//
//error: no valid connection//
//error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such
file or directory/
You need to run the daemon as root if you want it to listen on
/var/run/libvirt/libvirt-sock
Got it. Running both custom 1.2.0 daemon and virsh tool as root works
like a charm. :-)
And I need to kill custom daemon and restart 1.1.1 libvirtd to recover from
this. Any advice?
Finally (sorry about this large mail), there is one thing that does bother me
quite a lot.
Using custom virsh, command history seems to vanish, as I press Arrow-UP and I
get "^[[A" in the screen, instead of last command used. Tell me, please, that
this is just some silly config I need to adjust... :_(
Do you have the develompent headers for readline installed?
Jan
Ok, I've been missing the -dev package... When I installed it and then
made ./configure, I got 'READLINE_LIBS = -lreadline' which then enabled
the history in my custom virsh.
I don't know if this is related, but when I do a migrate command, it
turns down the password I enter, as if it's wrong written (and I trued
several times). I'll try to work through this.
Thank you for your time. :-)
