oeqa/runqemu: Support RUNQEMU_TMPFS_DIR as a location to copy snapshot images to
We have a working theory that IO queues on the autobuilder are impacting runtime testing under qemu, particularly async writes which inice does not influence. We already pass the snapshot option to qemu which copies the image and runs out of the copy. Add in the ability to copy the image to a specificed location which can be a tmpfs. This means that writes to the image would no longer be blocked by other writes to disk in the system. Preliminary tests show that this does improve the qemu errors at the expense of sometimes showing qemu startup timeouts as on a loaded system with a large test image, it can take longer than 120s to copy the image to tmpfs. Having a most consistent failure mode for loaded tests is probably desireable though. (From OE-Core rev: fd1c26ab426c3699ffd8082b83d65a84c8eb8bff) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
