qemu: improve detection of UNIX path generated by libvirt Currently we consider all UNIX paths with specific prefix as generated by libvirt, but that's a wrong assumption. Let's make the detection better by actually checking whether the whole path matches one of the paths that we generate or generated in the past. The UNIX path isn't stored in config XML since libvirt-1.3.1. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1446980 Signed-off-by: Pavel Hrdina <phrdina@redhat.com>

qemu: capabilities: Move setting QEMU_CAPS_DEVICE_VIDEO_PRIMARY to virQEMUCapsInitQMPBasicArch Until we clean up and remove all capabilities which no longer make sense to have separately, we should use virQEMUCapsInitQMPBasicArch to set the defaults as it's used by qemuxml2argvtest when testing with fake capabilities. This allows us to prevent testing dead code paths with the fake capability tests.

tests: Drop more QEMU driver config overrides These are allegedly necessary to keep the output consistent, but now that we're using a privileged config for the driver we get the desired behavior out of the box, and as a bonus the paths match what you would actually see on a regular host.

qemu: Generate shorter channel target paths A <channel/> device is basically an UNIX socket into guest. Whatever is sent from the host, appears in the guest and vice versa. But because of that, the length of the path to the socket is important (underscored by fact that we derive the path from domain short name). But there are still cases where we might not fit into UNIX_PATH_MAX limit (usually 108 characters), because the path is derived also from other variables, e.g. XDG_CONFIG_HOME for session domains. There are two components though, that are needless: "/target/" and "domain-" prefix. Drop them. This is safe to do, because running domains have their path saved in status XML and even though paths are dropped on migration, they are not part of guest ABI and thus we are free to change them.

qemu: Move channelTargetDir into stateDir For historical reasons (i.e. unknown reason) we put channel sockets into a path derived from cfg->libDir which is a path that survives host reboots (e.g. /var/lib/libvirt/...). This is not necessary and in fact for session daemon creates a longer prefix: XDG_CONFIG_HOME -> /home/user/.config XDG_RUNTIME_DIR -> /run/user/1000 Worse, if host is rebooted suddenly (e.g. due to power loss) then we leave files behind and nobody will ever remove them. Therefore, place the channel target dir into state dir.

qemu: Be less aggressive when dropping channel source paths In v9.7.0-rc1~130 I've shortened the path that's generated for <channel/> source. With that, I had to adjust regex that matches all versions of paths we have ever generated so that we can drop them (see comment around qemuDomainChrDefDropDefaultPath()). But as it is usually the case with regexes - they are write only. And while I attempted to make one portion of the path optional ("/target/") I accidentally made regex accept more, which resulted in libvirt dropping the user provided path and generating our own instead.

qemu: populate <audio> element with default config Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable - VNC - set to "none", unless passthrough of host env variable is set - SPICE - always set to "spice" - SDL - always passthrough host env - No graphics - set to "none", unless passthrough of host env variable is set The setting of the QEMU_AUDIO_DRV env variable is done in the code which configures graphics. If no <audio> element is present, we now auto-populate <audio> elements to reflect this historical default config. This avoids need to set audio env when processing graphics.
