Re: [libvirt] [PATCHv2 04/20] snapshot: merge pre-snapshot checks

From: Eric Blake <eblake(a)redhat.com&gt; Both system checkpoint snapshots and disk snapshots were iterating over all disks, doing a final sanity check before doing any work. But since future patches will allow offline snapshots to be either external or internal, it makes sense to share the pass over all disks, and then relax restrictions in that pass as new modes are implemented. Future patches can then handle external disks when the domain is offline, then handle offline --disk-snapshot, and finally, combine with migration to file to gain a complete external system checkpoint snapshot of an active domain without using 'savevm'. * src/qemu/qemu_driver.c (qemuDomainSnapshotDiskPrepare) (qemuDomainSnapshotIsAllowed): Merge... (qemuDomainSnapshotPrepare): ...into one function. (qemuDomainSnapshotCreateXML): Update caller. --- src/qemu/qemu_driver.c | 92 +++++++++++++++++++------------------------------- 1 file changed, 34 insertions(+), 58 deletions(-)
