Re: [libvirt-users] qemu-img snapshot on running virtual machine

For a running domain, you need to go through libvirt and also save the
memory of the VM - doing just the disk snapshot for a running machine
would be an equivalent of copying a physical hard drive after pulling
out the power cord.

Hi Jan, I 100% agree that taking a snapshot without dumping the memory
content would be akin to "pulling the plug" on the guest.
However, I was speaking about disk image file consistency. In other
words: does taking a snapshot of an in-use virtual disk have a chance to
corrupt the *original* disk Qcow2 image file?
Thanks.
