February 17, 20233 yr Hi Guys, I really need to make use of the virsh snapshots because I need to do some extensive tests on an old rhel6 vm so did some digging how to manage it. I installed an oracle linux 6 vm ( is rhel 6) and after some trial and errors I could successfully create snapshots (having a new snapshot file) and revert to the base image. Is not even that complicated (thought it would be) - to make sure the snapshot is create in the ol6 directory I first cd into /mnt/user/domain/ol6 virsh snapshot-create-as ol6 snapshot0 --description "first snapshot" --disk-only virsh snapshot-current ol6 virsh snapshot-current ol6 --name On disk a file got created "vdisk1.snapshst0" - sweet. The I updated the os with the usual "yum check-update && yum update". The new file got larger during the update process. Sweet. I could easily revert with virsh snapshot-revert ol6 snapshot0. And then when I rebooted unraid virsh no longer knows about the snapshot.. I assume the snapshot information is kept in memory then rather than stored on the usb ? How can I fix this? -
March 6, 20233 yr Author anyone got a tutorial on how to handle and manage snapshots with virsh or qemu-img on unraid ?
