Re: Concurrent scanning of same disk
...pshot, then I
resume the guest. Proof is that I can clearly analyse the memory core dump
without any problem.
Maybe I am breaking the disk's consistency once I extract the dump through
the qemu-img command?
The command is:
qemu-img convert -f qcow2 -o backing_file=guest_disk.qcow2 -O qcow2 -s
snapshot_n guest_disk.qcow2 new_disk_for_libguestfs.qcow2
Could it be that, as the backing file is pointing to the guest's disk which
will evolve in time, when guestfs tries to read the data sees
incosistencies?
The guest_disk.qcow2 is a COW clone of a base_disk.qcow2, what if I rebase
the new_disk_for_...

contains the guest's memory, so it's not relevant for consistency.

Is the guest paused when you do this? If not, then this will create
an inconsistent snapshot.
