Hi Kyle,
Thanks so much for your time and advice, I must say it's been far much helpful and I appreciate it.
I have upgraded to the most recent version of libvirt for AMD64 architecture which is 0.9.2-7
root@neutrino:~# virsh version
Compiled against library: libvir 0.9.2
Using library: libvir 0.9.2
Using API: Xen 3.0.1
Running hypervisor: Xen 4.1.0
root@neutrino:~#
The UNIX socket interface is enabled: (xend-unix-server yes). No clue about the Xen API line yet.
Here is a new phenomenon though:
root@neutrino:~# virsh -c xen:/// domxml-from-native xen-xm winxp.cfg > config.xml
error: An error occurred, but the cause is unknown
root@neutrino:~#
As you've perfectly described I can actually start the domain using: #xm create winxp.cfg. And again, the control is managed by
xm and # virsh list --all doesn't show anything. Virsh cannot create the domain since it is not in an XML format nor can it start it
because it is not a libvirt managed domain.
There are no last entries either in /var/log/messages or /var/log/libvirt/libvirtd.log. Virsh and virt-manager are working fine and can
indeed connect to the hypervisor.
And just one last question: remus (for HA), is independent of all the libvirt management and workarounds? I mean, can I use both things
at the same time?, because I see virsh / virt-manager can in fact migrate domains, but it is just live-migration and not intended for HA.
Thank you once again!
Tony.
