From 80dd5aff1b3273e0ee5bec379df62647c0b39c1c Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Wed, 13 Apr 2022 01:18:46 +0300 Subject: [PATCH 01/14] block: add 'force' parameter to 'blockdev-change-medium' command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 'blockdev-change-medium' is a convinient wrapper for the following sequence of commands: * blockdev-open-tray * blockdev-remove-medium * blockdev-insert-medium * blockdev-close-tray and should be used f.e. to change ISO image inside the CD-ROM tray. Though the guest could lock the tray and some linux guests like CentOS 8.5 actually does that. In this case the execution if this command results in the error like the following: Device 'scsi0-0-1-0' is locked and force was not specified, wait for tray to open and try again. This situation is could be resolved 'blockdev-open-tray' by passing flag 'force' inside. Thus is seems reasonable to add the same capability for 'blockdev-change-medium' too. Signed-off-by: Denis V.

QEMU tries to be as accurate as possible, and so in these test cases will include the filter that is part of the block graph in that backing file string (by virtue of making it a json:{} description of the post-commit subgraph). This makes little sense outside of QEMU, though: Specifically, the throttle node in that subgraph will dearly miss its supposedly associated throttle group object. When starting the commit job, we can specify a custom backing file string to write into said image file, so let’s use that feature to write the plain filename of the backing chain’s next actual image file there. Explicitly provide the backing file so that opening the file outside of QEMU (Where we will not have throttle groups) will succeed.

We make no effort to hide fusermount's error message (because it would be difficult, and because users might want to know about the fallback occurring), and so when allow_other does not work (primarily when /etc/fuse.conf does not contain user_allow_other), this error message will appear and break the reference output. We do not need allow_other here, though, so we can just pass allow-other=off to fix that.
