Public bug reported: libvirt driver
Login a deployed VM and write some files, for example: ``` [lynn@host-172-26-105-43 ~]$ ls -lrt ... -rw-rw-r--. 1 lynn lynn 677 Jun 29 06:30 sum -rw-rw-r--. 1 lynn lynn 38 Jun 29 06:30 sum3.md5 [lynn@host-172-26-105-38 ~]$ ``` then *right* after the file created, trigger the snapshot action of the VM after that, deploy a new VM through the created image found some files missing (e.g sum3.md5 file) ``` [lynn@host-172-26-105-43 ~]$ ls -lrt ... -rw-rw-r--. 1 lynn lynn 648 Jun 29 06:30 sum [lynn@host-172-26-105-43 ~]$ ``` I checked the code and seems no flush operation in live or cold snapshot (cold seems suspend the VM only) https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L2952 is it by design or best practice ? ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
