[PATCH 0/3] block: Fix external snapshot with VM state |
Date: |

This fixes bdrv_invalidate_cache_all() for some kinds of graphs where
part of the nodes are active and others are inactive. This is a scenario
that happens when libvirt takes an external snapshot with VM state.
This was reported in:
https://bugzilla.redhat.com/show_bug.cgi?id=1781637
('qemu crashed when do mem and disk snapshot')
Based-on: <address@hidden>
('iotests: Remove duplicated blockdev_create()')
Kevin Wolf (3):
block: Activate recursively even for already active nodes
hmp: Allow using qdev ID for qemu-io command
iotests: Test external snapshot with VM state
