...protecting against name and UUID changes? Then compile my own libvirt... The comment in the code says name can be changed, but I'm guessing I would have to change the UUID too. Does anyone see how that would create issues? I'm not sure how libvirt uses the UUID internally. -- Regards Jonas Finnemann Jensen.

...ble with libvirt, or am I better off using QEMU directly? and how? I couldn't do internal snapshots with --live, and snapshot-revert says it can't revert to external snapshots yet :) (using QEMU directly would certainly leave me with a lot of manual network configuration) -- Regards Jonas Finnemann Jensen. 2016-04-19 2:23 GMT-07:00 Martin Kletzander <mkletzan@redhat.com>: > On Mon, Apr 18, 2016 at 10:05:02PM +0300, Michael Ravits wrote: > >> Hi Jonas, >> >> I asked a similar question here last week.

...ter management. I'm not sure why it couldn't be done. But honestly hacking libvirt to violate a core invariant is probably asking for trouble :) Den 19. apr. 2016 11.17 PM skrev "Martin Kletzander" <mkletzan@redhat.com>: > On Tue, Apr 19, 2016 at 03:22:18PM -0700, Jonas Finnemann Jensen wrote: > >> >>> You'll also need to change the name and uuid of the domain at the very >>> least. >>> >> >> Agree, but is that possible with libvirt? >> >> > Not in a supported way.

...d a similar question here last week. You could find it by searching for this topic in the mailing list archives: "Clone VM with saved state". That being said I'd be very glad if you could update here when you find a complete solution. - Michael On Mon, Apr 18, 2016 at 9:49 PM, Jonas Finnemann Jensen <jonasfj@mozilla.com > wrote: > Hi, > > I would like to save a running domain (ie. disk + memory) and be able to > restore it multiple times creating duplicates of the orignal domain all > starting from the same state. > Use case: > I'm building a task-process...

...rk cable before I save the VM memory, and plugging it back in after I load the VM, then DHCP would run immediately. As an added benefit any guest program I have talking to my meta-data service would be able to detect that the VM has been loaded, by looking for network connection. -- Regards Jonas Finnemann Jensen. 2016-04-19 14:26 GMT-07:00 Laine Stump <laine@laine.org>: > (please don't top-post.
