	Launching the destination VM before the source VM gives us a regression test for HEAD^: The guest device causes a read from the disk image through guess_disk_lchs(). This will not work if the first sector (containing the partition table) is yet unallocated, we use COR, and the node is inactive. By launching the source VM before the destination, however, the COR filter on the source will allocate that area in the image shared between both VMs, thus the problem will not become apparent. Switching the launch order causes the sector to still be unallocated when guess_disk_lchs() runs on the inactive node in the destination VM, and thus we get our test case.

2019-08-16	iotests: Test migration with all kinds of filter nodes	Kevin Wolf	1	-0/+17
	This test case is motivated by commit 2b23f28639 ('block/copy-on-read: Fix permissions for inactive node'). Instead of just testing copy-on-read on migration, let's stack all sorts of filter nodes on top of each other and try if the resulting VM can still migrate successfully. For good measure, put everything into an iothread, because why not? Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com>
