And prior to taking the snapshot a warning in red at the bottom of the dialog (that check happens when you open the dialog, so it may not be 100% reliable) if you want to doublecheck then this is noticable in vdsm.log. First we try to take the snapshot with fsfreeze, and only when it fails we take it again without it. fsfreeze the command executed at VM OS level or any other low level command? It’s a matter of Linux and Windows implementation, they both have an API supporting that at kernel level. I’m not aware of filesystem limitations. If you use Windows and the qemu-ga, it'd call VSS, which, if supported by applications (ranging from Notepad to SQL server) will provide application consistent snapshot. Y.
