Maybe the line:
exclude disk 'ide0' (backup=no) ?
In my opinion the vzdump process seem too fast ...may be it exclude some disk ?

But he can't find the boot disk !

Thanks
 
No error on the shell:
qm start 303
303 IMPA03 running 4096 32.00 7711

But if i open the console:
No bootable devices ...
 
You exclude the boot disk from the backup and wonder, the boot disk is not in the backup.

If you want to be able to restore, you have to include the boot disk ide0 in the backup.
 
I have used the web interface ( Backup now button ).
Have i to use vzdump from command line with some addition par to include boot disk ?
Thanks

Click to expand...

In your VM hardware tab, the IDE0 disk is excluded.
 
I have modify the restored conf file:
-----------------------------------------------------------------------------------------------

boot: c
bootdisk: ide0
cores: 2
ide0: local-zfs:vm-303-disk-1,cache=writethrough,size=42G

ide2: local:iso/CentOS-7-x86_64-DVD-1503-01.iso,media=cdrom

But it still fail .. can't find the boot disk.
How can include ide0 using vzdump ?

Thanks!
 
funny idea but changing on the restored config file cannot magically include data.

you need to include the boot disk, and create a NEW backup.
 
Thanks for the funny idea ;-)
But how can i include it ?
hav i to modify something on the source vm conf file ?
The default vzdump can't include it
Thanks!
 
You created a backup without the boot disk.
Therefore, you cannot restore it.

What is your real question?
