This would normally allow you to change the disk from thick to thin, when that is done you could opt to change it to lazy zeroed later.<br />

Eager zero and lazy zero needs some sort of thin provisioning in underlying storage, invisible to vmware. If on ISCSI there is no difference in consumed size, just that blank spaces are either zeroed while copying or left unwritten. in later case obviously thin provisioning on storage backing LUN has a chance to do something.

one can do vmotion without converter and convert disk format.

<div class="content wysiwyg-content">
I have a vmware virtual machine/template that is currenly set as eager zero. I am trying to convert it over to lazy zero however it does not seem to be taking. <br />
<br />
So far I have tried<br />
<br />
1. Storage Vmotion selecting thick lazy zero as the format. (The vmotion completes however the disk is still eager zero)<br />
2. I have tried cloning the VM and setting the format as lazy zero (the clone completed however the disk is still eager zero)<br />
<br />
Is there any way to get this vm/template to lazy zero?

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.
