[qemuserver.pm, proxmox.com] Subject: [pbs-devel] [PATCH qemu-server] cdrom handling: default to "none" if no physical drive is available X-BeenThere: pbs-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Backup Server development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 16 Dec 2022 15:07:55 -0000 when a vm is configured to use the physical cd rom drive but there is no such drive a cryptic "uninitialized value" error is thrown. this is due to the `$path` not being defined in `sub print_drive_commandline_full` in this case. warn that no cd rom drive is available and default back to using "none" as media instead. note that the error was basically cosmetic as the vm would start just fine. forum thread: https://forum.proxmox.com/threads/use-of-uninitialized-value-path-in-pattern-match-m-at-usr-share-perl5-pve-qemuserver-pm-line-1622.119592/ Signed-off-by: Stefan Sterz --- PVE/QemuServer.pm | 3 +++ 1 file changed, 3 insertions(+) diff --git a/PVE/QemuServer.pm b/PVE/QemuServer.pm index dd6ea3e..bc935df 100644 --- a/PVE/QemuServer.pm +++ b/PVE/QemuServer.pm @@ -1292,6 +1292,9 @@ sub get_cdrom_path { return $cdrom_path = "/dev/cdrom" if -l "/dev/cdrom"; return $cdrom_path = "/dev/cdrom1" if -l "/dev/cdrom1"; return $cdrom_path = "/dev/cdrom2" if -l "/dev/cdrom2"; + + warn "there is no physical cdrom drive that can be used. defaulting back to 'none'."; + return ''; } sub get_iso_path { -- 2.30.2
