Hi, I am trying to create Guest OS (VM) in virtualBox throught libvirt. I installed libvirt 0.7.0 and created the template as <domain type='vbox'> <name>ubuntu</name> <os> <type>hvm</type> <boot dev='hd'/> </os> <memory>542720</memory> <vcpu>1</vcpu> <devices> <disk type='file' device='disk'> <source file='/home/santhosh/Desktop/ubuntu9.vdi'/> <target dev='hdd'/> </disk> <graphics type='rdp' port='3386'/> </devices> </domain> Then I issued this command $ virsh -c vbox:///session define /home/santhosh/Desktop/ubun.tmpl Domain ubuntu defined from /home/santhosh/Desktop/ubun.tmpl When I open VirtualBox, it has created a domain named "ubuntu". All the parameters specified in the template file are set except "Hard disks" . So, when I start the VM, I am left with boot errors 00:00:06.318 Guest Log: BIOS: int13_harddisk: function 02, unmapped device for ELDL=80 00:00:06.319 Guest Log: BIOS: Boot from Hard Disk 0 failed 00:00:06.321 Guest Log: Could not read from the boot medium! System halted. It is unable to boot from the disk image which I specified in the template and I am sure the path specified to disk image in the template is correct. I am unable to diagnize and find where is the error. Can any one help me here to know what might be the problem and what should I do. Thank you.
