From a2faa7d57ea997e4194e95a5ccdf2b9e41376f55 Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Tue, 6 Aug 2024 08:51:29 +0100 Subject: [PATCH] Update common submodule Considerable changes have been made in virt-v2v to how powershell scripts are run in Windows guests, and to qemu-ga installation (also for Windows). This pulls in the following commits: Richard W.M. Jones (10): mlcustomize: firstboot: Use Linux path for Powershell script path mlcustomize: firstboot: Use powershell.exe instead of path mlcustomize: firstboot: Use Powershell -NoProfile flag mlcustomize: Revert delay installation of qemu-ga MSI mldrivers/linux_kernels.ml: Prefix general information with ^info: mlcustomize: Use Start-Process -Wait to run qemu-ga installer mlcustomize: Add Firstboot.firstboot_dir function mlcustomize: Place powershell scripts into \Temp mlcustomize: Inject qemu-ga & blnsvr into /Temp mlcustomize: Write qemu-ga log file name to log.txt (cherry picked from commit b8d57760ea9c9d3ec7a21ee41d74731ab81173df) --- common | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) Submodule common 830cbdcf4..7b84a370e: diff --git a/common/mlcustomize/firstboot.ml b/common/mlcustomize/firstboot.ml index 5dc012340..3bbba714d 100644 --- a/common/mlcustomize/firstboot.ml +++ b/common/mlcustomize/firstboot.ml @@ -239,7 +239,22 @@ WantedBy=%s end module Windows = struct - let rec install_service (g : Guestfs.guestfs) root = + (* Create and return the firstboot directory. *) + let create_firstboot_dir (g : Guestfs.guestfs) = + let rec loop firstboot_dir firstboot_dir_win = function + | [] -> firstboot_dir, firstboot_dir_win + | dir :: path -> + let firstboot_dir = + if firstboot_dir = "" then "/" ^ dir else firstboot_dir // dir in + let firstboot_dir_win = firstboot_dir_win ^ "\\" ^ dir in + let firstboot_dir = g#case_sensitive_path firstboot_dir in + g#mkdir_p firstboot_dir; + loop firstboot_dir firstboot_dir_win path + in + loop "" "C:" ["Program Files"; "Guestfs"; "Firstboot"] + + let rec install_service (g : Guestfs.guestfs) root + firstboot_dir firstboot_dir_win = (* Either rhsrvany.exe or pvvxsvc.exe must exist. * * (Check also that it's not a dangling symlink but a real file). @@ -254,20 +269,7 @@ module Windows = struct error (f_"One of rhsrvany.exe or pvvxsvc.exe is missing in %s.
