Enter the name for the new virtual machine. If the backup was created by Agent for VMware or
Agent for Hyper-V, the software takes the name from the virtual machine configuration contained in
the backup.
Processors
Initial setting: if not contained in the backup or if the backed-up setting is not supported by the
virtualization server, it is the default server's setting.
This is the number of processors of the new virtual machine. In most cases, it is set to one. The result
of assignment of more than one processor to the machine is not guaranteed. The number of virtual
processors may be limited by the host CPU configuration, the virtualization product and the guest
operating system. Multiple virtual processors are generally available on multi-processor hosts. A
multicore host CPU or hyperthreading may enable multiple virtual processors on a single-processor
host.
6.3 Recovery to a manually created virtual machine
This section describes the conversion method (p. 131) in which you create a virtual machine yourself
and perform a recovery to it as if it were a physical machine.
6.3.1 Considerations before conversion
Converting a UEFI-based machine
If the original machine uses Unified Extensible Firmware Interface (UEFI) for booting, consider
creating a virtual machine that is also UEFI-based.
If your virtualization product does not support UEFI, you can create a BIOS-based machine, provided
that the original machine is running Windows. Acronis Backup adjusts the Windows boot mode to
the BIOS boot firmware and ensures that Windows remains bootable.
For Linux operating systems, changing the boot mode from UEFI to BIOS is not supported. Acronis
Backup can convert a UEFI-based machine running Linux only when the machine uses GRUB version 1
and the target machine is also UEFI-based. For more details, see "Support for UEFI-based machines"
(p. 34).
Choosing the disk interface
When creating the virtual machine, you may want its disks to have a different interface than those of
the original machine.

You may want to change all disk interfaces from IDE to SCSI when migrating a machine to ESX(i),
because SCSI is a default disk interface for ESX(i) and it provides better performance.

You need to change the system disk interface from SCSI to IDE when migrating a machine to
Hyper-V, because Hyper-V does not support booting from SCSI disks.
If the original machine uses a custom boot loader, either recover the system disk to a disk with the
same interface, or manually configure the boot loader. The reason is that when the interface of the
system disk changes, the name of the boot device also changes; however, the boot loader still uses
the old name. Configuring GRUB is normally not needed because Acronis Backup does this
automatically.
