Identify the VM disks
name = "pladm" [...] vif = [ 'bridge=vbr61,mac=zzz' ] disk = [ 'phy:/dev/vgxen_raid10/pladm_root,xvda,w', 'phy:/dev/vgxen_raid10/pladm_data0,xvdb,w', 'phy:/dev/vgxen_raid10/pladm_data1,xvdc,w', ] serial='pty'
Shut down the vm
xl shutdown pladm
Mount /var/lib/one to /mnt/one
and use the uploads directory to supply the vm image:
xyz:/xen/configs# for vbd in /dev/vgxen_raid10/pladm_* ; do dd if=$vbd bs=1024k | cp --sparse=always /proc/self/fd/0 /mnt/one/upload/$( basename $vbd) done
Including cp with --sparse=always enforces sparsifying the image, which works better than dd conv=sparse. Apparently :-)
The following blog entry is where I learned about using cp as sparsifier:
