Hi
I was trying out the libxl backend of xen 4.3 with libvirt, but I found it
very unstable and unusable.
I'm in xen 4.3 dom0 and starting:
1. xen stuff:
echo "Starting Xen..."
/etc/init.d/xencommons start
#/etc/init.d/xend start
. /etc/rc.d/rc.xen_bridge start
/etc/init.d/xendomains start
#libvirtd -l -d
hsflowd
2. Starting libvirt -v to see what is going on.
After that I'm using virsh to do some simple tasks:
virsh # list
Id Name State
----------------------------------------------------
Where is dom0?
virsh # create debian_pv.xml
error: Failed to create domain from debian_pv.xml
error: End of file while reading data: Input/output error
error: One or more references were leaked after disconnect from the
hypervisor
error: Failed to reconnect to the hypervisor
And log from libvirt:

Why crash?
Am I doing something wrong?
