does't support revert and delete the external snapshot which the raw disk
based guest.My libvirt and qemu release are both 3.2.0.So I have a question,the
community how to solve it,if have any plans about it.Can you tell me more about
it?Thank you very much.

The plans for fixing this are indefinite though. I'll probably work on it but currently I'm working on '-blockdev'-izing of the qemu driver so I can't really tell you any time frame.
Thank you,Do you want to say the qemu does not really want to go forward with "external" snanpshots just now?Do you know why the qemu doesn't want to support it?The external snapshot is so important to our users.Thank you! ------------------ Original ------------------ From: "Peter Krempa"; Date: 2018年2月8日(星期四) 晚上11:22 To: "李杰"; Cc: "libvirt-users"; Subject: Re: [libvirt-users] Ask question On Thu, Feb 08, 2018 at 22:33:05 +0800, 李杰 wrote:> Dear > > > Recently,I am interested in libvirt,but I found the libvirt does't support revert and delete the external snapshot which the raw disk based guest.My libvirt and qemu release are both 3.2.0.So I have a question,the community how to solve it,if have any plans about it.Can you tell me more about it?Thank you very much.Adding support for deleting and reverting external snapshots is desired since qemu does not really want to go forward with internal snanpshots.
