Hi @Arnau Colldeforns ,
what does "I have lost my SQL Virtual machine"? Deleted by accident? Normally an Azure VM doesn't disappear for a sudden ;-)
First of all: Do you have a backup of the VM? If yes, just restore the VM from the latest backup.
If no backup exists please check if the disks of the VM are still existing.
Azure Portal -> Disks -> search for the disks related to the VM.
If the disk are still existing you should be able to create a new VM using the OS disk and attach the additional data disks.
If the disks are not existing there is now way to recover the VM. Sorry to say.
