#9057 obsolete Dos slow. >10x compared to other host. VBox GUI slow. Charlie
Description

i have a boot floppy that simply boots to dos. it includes an archive of utilities in a CAB file. it extracts the contents to a ram drive. i did have a USB HDD connected, and a CD image from the network connected - same if not connected.

the decompression runs slow on vbox, like 10x or more slower compared to:

i ran same images on a windows 2000 machine (old vbox), although the dos USB drivers caused old vbox to hang, the other FDD image without USB ran fine and faster. 4s for a file compared to >40s.

CPU is close to 50%, system is vista ultimate, 4.0.8 vbox

also when opening things, ie going to change if the USB HDD is connected or not also causes the lag, so not specifically a virtualization problem. same for choosing the CD or HDD images. the frame appears, the CPU is 50% for a short time then the contents of the "settings" appears.

windows XP emulated system seems to run fine. cannot remember if i saw the gui problems earlier, but now i do because DOS is so slow. simply entering C: (return) did nothing and i gave up.

#9061 obsolete 3 VM servers all became unresponsive Jordie
Description

All three virtual machines were running on Win7 Host with 16 Gig of RAM:

VM Primary Domain Controller VM SQL Server 2008R2 VM SharePoint 2010 Foundation WFE Pod 0

  • I switched to VM SharePoint 2010 Foundation WFE Pod 0 server
  • I mounted an ISO disk - the virtual system became unresponsive
  • I waited close to 15 minutes - no change in response
  • I switched to VM SQL Server 2008R2, and "saved the machine state" - then this virtual system began not responding
  • I switched to the VM Primary Domain Controller to "pause it".
  • It Paused ok
  • Then un-paused VM Primary Domain Controller
  • This system then became unresponsive.
  • Attempted go to the Oracle VM Box Manager - it became unresponsive.

#9067 obsolete Linux kernel warnings when trying to remount a shared folder Eugene
Description

When I try to remount a shared folder on a Linux guest, it fails and the guest kernel issues several warnings that may indicate that some problem has occured. The steps to reproduce are as follows:

First I mount a shared folder "vbshare" to /mnt/shared:

#> mount -t vboxsf vbshare /mnt/shared

So far so good. Now I try to remount it read only:

#> mount -t vboxsf -o remount,ro vbshare /mnt/shared 
/sbin/mount.vboxsf: mounting failed with the error: Invalid argument

In the system log on the guest there are several warnings triggered in the kernel during the execution of sf_read_super_26() (see the attached system.log file for details):

  • WARNING: at /build/buildd/linux-2.6.38/fs/sysfs/dir.c:455 sysfs_add_one+0xc8/0xf0()

Hardware name: VirtualBox sysfs: cannot create duplicate filename '/devices/virtual/bdi/vboxsf-vbshare'

  • kobject_add_internal failed for vboxsf-vbshare with -EEXIST, don't try to register things with the same name in the same directory.
  • And 3 more.

At the end, the log shows that sf_read_super_aux() returned -EINVAL (-22) and mounting failed indeed.

Guest: Ubuntu 11.04 x64, kernel 2.6.38-8-generic, this problem showed up on other systems too.
Host: Windows XP SP3
