xe pool-restore-database do not restore the system properly

xe pool-restore-database do not restore the server state compeletely

After installing Xenserver with one VM, creating snapshot for VM, setup autostart for server and VM to "enabled" and setup network configurations and bonding I run

xe pool-dump-database file-name=pool.dump
service xapi stop
BackUpXenPath "/etc/xensource"
BackUpXenPath "/var/lib/xcp"

After restoring the configuration by

rm -rf /var/xapi/networkd.db
RestoreXenPath "/etc/xensource"
RestoreXenPath "/var/lib/xcp"
xe-reset-networking --master=$IP --device=$NIC --mode=static --ip=$IP \
   --netmask=$NETMASK --gateway=$GW --dns=$DNS

-- the host reboots --

xe pool-restore-database file-name=pool.dump --force

BackupXenPath and RestoreXenPath is shell functions to save/restore files from the folder

I found some problem:

1. VM lost all its disks though the disks are still on the storage. I have to restore VM from snapshot to make it working and remove orphan disk images.
2. Sometimes network bonding do not restore or existing bonds remove
3. Autostart for the host and for VM becomes 'disabled' and I have to enable it by hands.

I use the same save/restore sequence in XenServer 6.5 without any problem
