Re: [libvirt-users] Rollback to running VM

  Thanks! The vanilla snapshot-create-as and revert commands work just exactly the way I’d want them to. I’d gotten a bit confused by the documentation and went down a rabbit hole with external snapshots.   Is there any way to make the snapshot and restore faster, like maybe by a decimal order of magnitude? For example, will PXE booting the VM and running it entirely off of a RAM disk and also using a RAM disk for the backing store help?   --  Gary Jackson   *From: *Doug Hughes <doug.hughes(a)keystonenap.com&gt; *Date: *Tuesday, September 19, 2017 at 11:25 AM *To: *"Jackson, Gary L." <Gary.Jackson(a)jhuapl.edu&gt;, &quot;libvirt-users(a)redhat.com&quot; <libvirt-users(a)redhat.com&gt; *Subject: *Re: [libvirt-users] Rollback to running VM   According to this page: https://wiki.libvirt.org/page/Snapshots <https://wiki.libvirt.org/page/Snapshots> It saves complete memory state, or crash-consistent disk state, but not both. You probably want to test it thoroughly and see how it does.  I only use the disk-consistent snapshots.
