A recent hardware or software change might be the cause. However I'm stuck with a Windows Error Recovery: Windows failed to start.

Attach the newly created win2008_v2.vmdk file to a newly created guest with default settings.vmkfstools -i win2008.vmdk -d thin win2008_v2.vmdk on the VMware host.qemu-img convert -p -f qcow2 -O vmdk win2008.qcow2 win2008.vmdk using qemu v4.2.1.I tried to follow recommendations from Convert qcow2 to vmdk and make it ESXi 6.0 Compatible and steps I found on the web: I realize the Win2008 VM is old and beyond EoS but need to keep this in place for now and is in a VLAN that is not internet accessible. If you do this on the parent image of a View Pool the changes won’t be “pushed” out to the VM’s within the Pool until your next recompose.I'm trying to move an old Win2008 server from KVM to VMware ESXi 6.7. If all went well you should now have a smaller VMDK file and newly reclaimed space! Once complete, again check the size by repeating step 2.Now we’ll punch all the zeroed blocks out of the VMDK file by typing, replacing with the name of the VM VMDK file:.Power off the VM and SSH into your ESXi host and navigate to the VMDK’s datastore -> directory and check the VM’s current size by typing:.Note: In Linux VM’s you’ll want to run this command, replacing with the actual path of the storage: dd if=/dev/zero of=//zeroes bs=4096 & rm -f //zeroes Download SDelete onto the VM you want to shrink and run the following command, replacing with the actual drive letter to be reduced:.A simple way of doing this is by using a free utility called SDelete from Sysinternals. While there isn’t a simple, one click button in the View Administrator Console there is a fairly easy manual method using vmfkstools.īefore we can use “vmkfstools” to shrink the VMDK file we must zero out any unused space on the thin provisioned disk. When maintaining a Horizon View environment I like to keep my parent images as small as possible and over time a thin provision disk can start to grow on you if you don’t watch it – be it from downloading installers, updates, or even running disk defrag.
