Fix libvirtd start issue#2519

WalkthroughBoth files had SR-IOV (Single Root I/O Virtualization) related checks and error handling removed. The pcicheck.php script now only performs PCI device change detection, while the qemu script removes the SR-IOV branch from its PCI checking logic. Both changes simplify their respective control flows. Changes

17-19: Avoid corrupting “yes/no” output with CLI$_SERVER['DOCUMENT_ROOT']noticesWhen run via CLI,
$_SERVER['DOCUMENT_ROOT']is commonly unset; if notices are displayed, they’ll pollute stdout and can break any consumer expecting exactlyyes/no.Proposed fix
-$docroot ??= ($_SERVER['DOCUMENT_ROOT'] ?: '/usr/local/emhttp'); +$docroot ??= (($_SERVER['DOCUMENT_ROOT'] ?? '') !== '' ? $_SERVER['DOCUMENT_ROOT'] : '/usr/local/emhttp'); require_once "$docroot/webGui/include/Helpers.php";
23-35: Make output parsing robust: drop== true, add newline, and guard$argvProposed fix
-$pci_addresses = []; -foreach ($argv as $arg) { +$pci_addresses = []; +foreach (($argv ?? []) as $arg) { if (preg_match('/"host"\s*:\s*"([^"]+)"/', $arg, $matches)) { $pci_addresses[] = $matches[1]; } } foreach($pci_addresses as $pciid) { if (isset($pci_device_changes[$pciid])) { $pcierror = true; + break; } } -echo $pcierror == true ? "yes" : "no"; +echo $pcierror ? "yes\n" : "no\n";

Learning: In the file emhttp/plugins/dynamix/include/SriovHelpers.php, the global variable $allowedPCIClass is defined and is used in emhttp/plugins/dynamix/include/SysDevs.php which includes SriovHelpers.php. This variable should not be flagged as unused.

Timestamp: 2025-12-28T15:54:58.673Z
Learning: In the unraid/webgui codebase, CSRF validation is centralized in the global auto_prepend_file (local_prepend.php) which runs before every PHP request. Do not add per-script CSRF checks in individual files like Browse.page or Control.php. If a script relies on global validation, ensure it does not duplicate CSRF logic; otherwise extend the central preface to cover the needed checks.
