Incorrect Disk Size Applied When Creating VM using Instance Type and Bootable Volume Sourced from Volume Snapshot. 

4.18.27, 4.19.21

100 %

1. Create a Snapshot from VM.

2. Create a bootable Volume. Go to "Bootable Volumes" --> Add Volume —> With Form —> Source Type “Volume Snapshot” —> Select the Volume Snapshot name recently created —> Adjust the disk size as the Original VM disk --> Save

3. Create New VM from Instance Type —> Under Select Volume to boot from —> Select the New Bootable Volume from list —> The disk size is take correctly under “VirtualMachine detail”. However when we create VM it changes back to 30GB.  

Disk size not honoured and it changes back to 30GiB after the VM is created.

Disk Size should be retained as it is on the Bootable volume selected
