#19130 obsolete screen resolution not restored at boot none Harry M
Description

Not sure if this is a vbox bug or artix bug, but maybe this can help determine which. After setting the screen resolution and rebooting, the screen comes up looking like https://www.pastepic.xyz/image/screenshot-2019-12-04-03-00-18.5tFm7.

You can see the screen resolution really is set correctly: https://www.pastepic.xyz/image/screenshot-2019-12-04-03-02-16.5tIyz.

The Guest Additions are up-to-date: https://www.pastepic.xyz/image/screenshot-2019-12-04-03-04-01.5td3P

The firefox browser can be viewed by dragging it around into the viewable area, and you can see that I was able to snapshot the monitor configuration program as well as a terminal, so the system seems to be working correctly outside of the graphics.

Please note that I disabled 3D thinking that might help, but it didn't. Video has the full 128MB. There is enough memory I think: https://www.pastepic.xyz/image/screenshot-2019-12-04-03-20-52.5tvuv

I admit this could be an issue with the particular configuration of this distro, which is artix, an arch-based distro without systemd. This is a recent issue that has only started NOTICING since the last GAs and/or the last repo updates -- I really don't know which might be contributing because I generally leave my VMs running for weeks at a time, unless there is some reason to restart them. I know I did not see this problem prior to this.

Other VMs have experienced problems in the same period, but they are of a different nature. In one case, I had to switch display managers from slim to lightdm because slim was experiencing long delays; again, that could well be a different issue.

Host is Devuan Ascii, with the latest updates applied.

Thank you for your POLITE responses. Please let me know if you need more information. I also realize that a maintenance update will probably be along in the next few weeks or so. Perhaps those will clear up my current issue.

#18724 fixed VBox 5.2.x: VBoxManage copyto --target-directory now requires an ending slash for guests => fixed in 5.2.x x>32 BP kboortz
Description

The "VBoxManage copyto" destination directory given to "--target-directory" for a Windows guest now requires an ending slash. I assume this is not an intentional change.

The error message when leaving out the ending slash in the destination "C:/tmp" is

VBoxManage: error: File copy failed VBoxManage: error: Copying file "/tmp/foo" to guest failed: VERR_ACCESS_DENIED VBoxManage: error: Details: code VBOX_E_IPRT_ERROR (0x80bb0005), component GuestSessionWrap, interface IGuestSession VBoxManage: error: Context: "int gctlCopyFileToDest(COPYCONTEXT*, const char*, const char*, gctlCopyFlags)" at line 2176 of file VBoxManageGuestCtrl.cpp VBoxManage: error: Copying file "/tmp/foo" to guest failed: VERR_ACCESS_DENIED. VBoxManage: error: Error processing "/tmp/foo", rc=VERR_GENERAL_FAILURE

#18737 fixed Linux guests: open(filename, O_CREAT|..., mode) fails inside shared folder => fixed in SVN/6.0.x x>10 BP jamesba
Description

The following C code produces a simple executable which will attempt to create and open a read only test file in a single operation.

Expected behaviour when run:

  • A newly created file called test.txt is created on disk with read only permissions
  • A read-write file-handle for the file is returned by the open call
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <errno.h>
#include <stdio.h>

int main() {
  int fd = open("test.txt", O_CREAT | O_EXCL | O_RDWR, 0444);

  if (fd < 0) {
    perror("Could not create file: ");
    return -fd;
  }

  return 0;
}

When run on other file systems this works correctly but when run on a virtualbox shared folder the file is created correctly but the program exits with the error message:

Could not create file: : Permission denied

This can be bypassed by running the command with sudo, in which case it succeeds normally.

This is not a purely hypothetical problem, since the same error occurs when attempting to use any programme that makes this system call, such as a git clone.
