It is my understanding that VMs must pause during Live Snapshot creation when "Save Memory" option is selected. If you're only seeking to mitigate against issues that might arise after doing package updates then what's the advantage of going with that route? Down the road does anyone know if it will be possible for oVirt and eventually RHEV to gather snapshots without Pausing VMs? Does Docker make this a feature we likely won't see developed? -- Thanks Douglas Duckworth, MSc, LFCS Unix Administrator Tulane University Technology Services 1555 Poydras Ave NOLA -- 70112 E: duckd@tulane.edu O: 504-988-9341 F: 504-988-8505

Do you mean not using VIR_DOMAIN_SNAPSHOT_CREATE_LIVE? Francesco, do you know why we are not using this flag? Down the road does anyone know if it will be possible for oVirt and
eventually RHEV to gather snapshots without Pausing VMs? Does Docker make this a feature we likely won't see developed?
I guess we should test this flag. Do you have any issues with the current code pausing vms when saving memory? Nir
