Do you mean starting my domain using -d option for qemu, which dumps the
log in /tmp/qemu.log ?
I mean libvirt.log. You can start libvirtd with these environment
variables:
LIBVIRT_DEBUG=debug LIBVIRT_LOG_OUTPUTS=1:file:/tmp/libvirt.log
I am using a VM started from virt-manager.... i don't see a way
to pass
-d to it from virt-manager... I can try using a hand-coded qemu cmdline
tho'
I assume when i am using python (import libvirt) and/or virsh.. it uses
qemu-kvm
qemu-kvm version is 1.0.1
Ok.
Do i need to try with latest qemu git ?
No, I don't think so, but you can try (1.4.0 or 1.5.0 will do).
On irc.. you asked me to check if cold-plug works.. but attach-device
is
for active domain only... am i missing something here ?
You can try putting the <disk> item and start the VM. In this case the
logs in /var/log/libvirt/qemu will be helpful, because they contain the
command-line that is used to start QEMU.
