Improve kvm vm snapshot #5836
Description
ISSUE TYPE
- Improvement Request
COMPONENT NAME
CLOUDSTACK VERSION
CONFIGURATION
OS / ENVIRONMENT
SUMMARY
We have achieved
xenserver: volume snapshot and vm snapshot
vmware: volume snapshot and vm snapshot
KVM+NFS: volume snapshot and vm snapshot
kvm +ceph: Only support volume snapshots;
kvm+ceph primary storage, it is a very perfect combination.
But we currently do not support KVM+ceph vm snapshots, I think this is a very large feature loss;
Libvrit api does not support vm snapshot in raw format (it may be the biggest obstacle to achieving this function).
We can refer to the openstack processing method:
- suspend the vm
- use the agent to connect to the ceph api to directly create a snapshot of all the volumes on the vm
- resume vm

@div8cn, there is a PR with a similar solution, but instead of suspending the VM, it will be frozen #3724

@slavkap can you confirm if the PR #3724 fixes this issue?

Hi @nvazquez, yes, it follows the described steps, but we freeze the VM instead of suspending it. It should work and for other storages as well

Thanks @slavkap, adding it to the 4.17 milestone tentatively

Hi @div8cn - PR #3724 addresses this issue and is ready now, could you please test it?
