Hi 

Have anyone else tried Libvirt support in VCL 2.3? 

I'm getting this error, not sure if it's specific to my configuration (# svn up 
At revision 1347799)

During base image capture VCL creates two files per VM in "Virtual Disk Path" 
folder (I'm using qcow2 disk format): 

qemu-img convert "/var/lib/libvirt/images/Linux_CentOS_62.img" -O qcow2 
"/var/lib/libvirt/images/baseImages/centos5image-linuxkvm898-v0.qcow2"
two files created:

centos5image-linuxkvm898-v0.qcow2
centos5-linuxkvm8-98-v0.xml

The content of centos5-linuxkvm8-98-v0.xml is:

# cat centos5-linuxkvm8-98-v0.xml HASH(0x154d9a50)

When I try to reload a computer with new image, VCL is trying to use .xml file 
as disk image and reload fails. 

Once I delete .xml and rename image file, it works fine:

rm -f centos5-linuxkvm8-98-v0.xml 
mv centos5image-linuxkvm898-v0.qcow2 centos5-linuxkvm8-98-v0.qcow2
