All the definitions of the VMs are periodically (1h) saved also on a special volume on the storage domain called OVF_STORE so you will find your existing VMs into the new engine and you will be able to start them from there. > > On Thu, Apr 11, 2019 at 6:13 PM Simone Tiraboschi <[email protected]> > wrote: > >> >> >> On Thu, Apr 11, 2019 at 9:46 AM Sakhi Hadebe <[email protected]> wrote: >> >>> Hi, >>> >>> We have a situation where the HostedEngine was cleaned up and the VMs >>> are no longer running.
